In most cities and counties, permits will be required for the installation of electrical circuits or the construction of exterior surfaces (decks and gazebos). In addition, some communities have adopted residential barrier codes which may require fencing and/or self-closing gates on the property to prevent unsupervised access to a pool (or spa) by children under 5 years of age. Your CALDERA spa is equipped with a locking cover that meets the ASTM F1346-91 Standard for Safety Covers, and as a result, is usually exempt from most barrier requirements. As a general practice, your local Building Department will inform you of any applicable barrier requirements at the time a permit is obtained for the installation of an electrical circuit. Your CALDERA dealer can provide information on which permits may be required.

Safety Information

IMPORTANT SAFETY INSTRUCTIONS (READ AND FOLLOW ALL INSTRUCTIONS)
AVOIDING THE RISK TO CHILDREN DANGER – RISK OF CHILD DROWNING
Extreme caution must be exercised to prevent unauthorized access by children. To avoid accidents, ensure that children cannot use a spa unless they are supervised at all times.
WARNING
To reduce the risk of injury, do not permit children to use this spa unless they are closely supervised at all times.

• To reduce the risk of injury, lower water temperatures are recommended for young children. Children are especially sensitive to hot water.

• Extreme caution must be exercised to prevent unauthorized access by children. To avoid accidents, ensure that children cannot use a spa unless they are supervised at all times.
  DO:

• Make sure you always lock the child resistant locks after using the spa for your children’s safety. Every CALDERA spa is equipped with a locking cover that meets the ASTM F1346-91 Standard for Safety Covers.

• Test the water temperature with your hand before allowing children to enter the spa to be sure that it’s comfortable. Children are especially sensitive to hot water.

• Remind children that wet surfaces can be very slippery. Make sure that children are careful when entering or exiting the spa.
  DON’T:

• Allow children to climb onto the spa cover.

• Allow children to have unsupervised access to the spa.
  AVOIDINGTHE RISK OF ELECTROCUTION
  DANGER – RISK OF ELECTROCUTION

• Connect only to a grounded source.

• Do not bury the power cord. A buried power cord may result in death, or serious personal injury due to electrocution if direct burial-type cable is not used, or if improper digging occurs.

• A ground terminal (pressure wire connector) is provided on the control box inside the unit to permit connection of a minimum No. 8 AWG solid copper bonding conductor between this point and any metal equipment, metal water pipe, metal enclosures of electrical equipment, or conduit within 5 feet (1.5 m) of the unit as needed to comply with local requirements.

• Do not operate the audio main controls while inside the spa (if spa is equipped with an audio component).

• Do not connect any auxiliary components (for example, cable additional speakers, headphones, additional audio components) to the audio system unless approved by Watkins Wellness .

• Do not self service audio component by opening spa door as this may expose dangerous voltage or other risk of injury. Refer all servicing to qualified service personnel.

• Do not attach an external antennae to a spa audio system unless installed by a licensed electrician in accordance with Article 810 of the National Electric Code, ANSI/NFPA 70.

WARNING

• To reduce the risk of electrical shock, replace a damaged cord immediately. Failure to do so may result in death or serious personal injury due to electrocution.
• Your spa is provided with a Ground Fault Circuit Interrupter (GFCI) for user and equipment protection. To ensure proper operation of this important safety device, test according to the following instructions per electrical configuration.
• Cord-Connected 115 volt, 20 amp models: The GFCI is located at the end of the power cord. Before each use, with the unit operating, push the TEST button. The unit should stop operating and the GFCI power indicator will go out. Wait 30 seconds and then reset the GFCI by pushing the RESET button. The GFCI power indicator will turn on, restoring power to the spa. If the interrupter does not perform in this manner, there may be an electrical malfunction and with it, the possibility of an electric shock. Disconnect the power until the problem has been corrected.
• 230 volt permanently installed or converted models:
• A ground terminal is provided on the terminal block (TB-1, system ground terminal) located inside the control box. To reduce the risk of electric shock, connect this terminal to the grounding terminal of your electrical service or supply panel with a continuous green, insulated copper wire. The wire must be equivalent in size to the circuit conductors supplying the equipment. In addition, a bonding terminal (pressure wire connector) is provided on the outside of the control box for bonding to local ground points. To reduce the risk of electric shock, this connector should be bonded with a No. 8 AWG solid copper wire to any metal ladders, water pipes, or other metal within 5 feet (1.5 m) of the spa to comply with local requirements. The means of disconnection must be readily accessible, but must be installed at least 5 feet (1.5 m) from the spa.
• Your spa is provided with a suitably rated circuit breaker to open all ungrounded supply conductors.
• Your spa uses ground fault circuit interrupters in the electrical subpanel. Before each use of the spa and with the unit operating, push the TEST button on each breaker. The switch should click over to the “Trip” position. Wait 30 seconds and reset each GFCI breaker by switching it completely off and then completely on. The switch should then stay on. If either of the interrupters does not perform in this manner, it is an indication of an electrical malfunction and the possibility of an electric shock. Disconnect the power until the fault has been identified and corrected. IMPORTANT: Failure to wait 30 seconds before resetting the GFCI may cause the spa’s Power Indicator (on the control panel) to blink. If this occurs, repeat the GFCI test procedure.

DANGER – RISK OF ELECTRICAL SHOCK

• Install at least 5 feet (1.5 m) from all metal surfaces. A spa may be installed within 5 feet (1.5 m) of a metal surface if each metal surface is permanently connected by a minimum No. 8 AWG solid copper conductor attached to the wire ground connector on the terminal box that is provided for this purpose if in accordance with National Electrical Code ANSI/NMFPA70-1993.
• Do not permit any electrical appliances, such as a light, telephone, radio, or television within 5 feet (1.5 m) of a spa. Failure to maintain a safe distance may result in death, or serious personal injury due to electrocution, if the appliance should fall into the spa.
• Install your spa is such a way that drainage is away from the electrical compartment and from all electrical components.

DO:

• Be sure your spa is connected to the power supply correctly – use a licensed electrical contractor.

• Disconnect the spa from the power supply before draining the spa or servicing the electrical components.

• Test the Ground Fault Circuit Interrupter before each use.

• Replace audio components only with identical components (if your spa is equipped with an audio component).
  DON’T:

• Use the spa with the equipment compartment door removed.

• Place electrical appliances within 5 feet (1.5m) of the spa.

• Use an extension cord to connect the spa to its power source. Thecord may not be properly grounded and the connection is a shock hazard. An extension cord may cause a voltage drop, which will cause overheating of the jet pump motor and motor damage.

• Attempt to open the electrical control box. There are no user serviceable parts inside.

RISKS TO AVOID
DANGER – RISK OF INJURY

• To reduce the risk of injury to persons, DO NOT remove suction fittings (filter standpipes) located in the filter compartment.
• The suction fittings in the spa are sized to match the specific water flow created by the pump. Never replace a suction fitting with one rated less than the flow rate marked on the original suction fitting.
• There is a danger of slipping and falling. Remember that wet surfaces can be very slippery. Take care when entering or exiting the spa.
• Never operate spa if the suction fittings are broken or missing.
• People with infectious diseases should not use the spa.
• Keep any loose articles of clothing, long hair, or hanging jewelry away from rotating jets or other moving components.

INCREASED SIDE EFFECTS OF MEDICATION

• The use of drugs, alcohol may cause unconsciousness with the possibility of drowning.
• Persons using medications should consult a physician before using a spa; some medication may cause a user to become drowsy, while other medication may affect heart rate, blood pressure, and circulation.
• Persons taking medications which induce drowsiness, such as tranquilizers, antihistamines, or anticoagulants should not use the spa.

HEALTH PROBLEMS AFFECTED BY SPA USE

• Pregnant women should consult a physician before using spa.
• Persons suffering from obesity, or with a medical history of heart disease, low or high blood pressure, circulatory system problems, or diabetes should consult a physician before using spa.

UNCLEAN WATER
Keep the water clean and sanitized with correct chemical care. The recommended levels for your CALDERA spa are:

With @ease Free Available Chlorine: 0.5-1.0 ppm| Without @ease Free Available Chlorine: 3.0-5.0 ppm| Total Alkalinity: 40-120 ppm
---|---|---
Water pH: 7.2-7.8| Calcium Hardness: 75-150 ppm|

Refer to Water Quality and Maintenance section for complete  instructions.
IMPORTANT: Turn on the jet pump for a least ten minutes after adding
ANY spa water chemicals into the filter compartment.
Clean the filter cartridges monthly to remove debris and mineral buildup which may affect the performance of the hydromassage jets, limit the flow, or trip the high limit thermostat, which will turn off the entire spa.
AVOIDING THE RISK OF HYPERTHERMIA
Prolonged immersion in hot water can result in HYPERTHERMIA, a dangerous condition which occurs when the internal temperature of the body reaches a level above normal 98.6°F (37°C). The symptoms of hyperthermia include unawareness of impending hazard, failure to perceive heat, failure to recognize the need to exit the spa, physical inability to exit the spa, fetal damage in pregnant women, and unconsciousness resulting in a danger of drowning.
WARNING
The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia in hot tubs and spas.
TO REDUCE THE RISK OF INJURY

• The water in the spa should never exceed 104°F (40°C). Water temperatures between 100°F and 104°F (36°C and 40°C) are considered safe for a healthy adult. Lower water temperatures are recommended for extended use (exceeding ten minutes) and for young children. Extended use can cause hyperthermia.
• Pregnant or possibly pregnant women should limit spa water temperatures to 100°F (36°C). Failure to do so may result in permanent injury to your baby.
• Do not use spa immediately following strenuous exercise.

AVOIDING THE RISK OF SKIN BURNS

• To reduce the risk of injury, before entering a spa the user should measure the water temperature with an accurate thermometer.
• Test the water with your hand before entering the spa to be sure it’s comfortable.

SAFETY SIGN
Each CALDERA spa is shipped with a SAFETY SIGN in the owner’s package. The sign, which is required as a condition of Product Listing, should be permanently installed where it is visible to the users of the spa. To obtain additional SAFETY SIGNS, contact your CALDERA dealer and request Part #70798.
IMPORTANT SPA INSTRUCTIONS
The following contains important spa information, and we strongly encourage you to read and apply them.
DO:

• Use and lock the vinyl cover when the spa is not in use, whether it is empty or full.

• Follow the Spa Care and Maintenance recommendations stated in this manual.

• Use only approved accessories and recommended spa chemicals and cleaners.
  DON’T

• Leave the CALDERA spa exposed to the sun without water or the cover in place. Exposure to direct sunlight can cause solar distress of the shell material.

• Roll or slide the spa on its side. This will damage the siding.

• Lift or drag the vinyl cover by using the cover lock straps; always lift or carry the cover by using the handles.

• Attempt to open the electrical control box. There are no user serviceable parts inside. Opening of the control box by the spa owner will void the warranty. If you have an operational problem, carefully go through the steps outlined in the Troubleshooting section. If you are not able to resolve the problem, contact your authorized CALDERA dealer. Many problems can easily be diagnosed over the telephone by an Authorized Service Technician.

SPA SHELL
Your CALDERA spa has an acrylic shell. Stains and dirt generally will not adhere to your spa’s surface. A soft rag should easily remove most dirt. Most household chemicals are harmful to your spa’s shell (see below for detailed information on cleaning agents). Always rinse off any spa shell cleaning agent with fresh water.
IMPORTANT:

1. The following products are the ONLY approved cleaning agents for your CALDERA spa shell: plain water, CALDERA Spa Shine, Brillianize® or Soft Scrub®  . The use of alcohol or any other household cleaner other than those listed to clean the spa shell
   surface is NOT recommended. DO NOT use any cleaning products containing abrasives or solvents since they may damage the shell surface, specifically: Simple Green® , Windex® or Spa Mitt. NEVER
   USE HARSH CHEMICALS! Damage to the shell by use of harsh chemicals is not covered under the warranty. Always rinse off any spa shell cleaning agent with fresh water.

2. Iron and copper in the water can stain the spa shell if allowed to go unchecked. Ask your CALDERA dealer about a Stain and Scale Inhibitor to use if your spa has a high concentration of dissolved minerals. (Watkins recommends Stain & Scale Defense.)

3. Keep all cleaners out of the reach of children and use care when applying.

Electrical Requirements

ELECTRICAL REQUIREMENTS AND PRECAUTIONS

QUICK START-UP INSTRUCTIONS
BEFORE YOU FILL YOUR SPA
Make sure your spa has been properly installed per all local codes, this includes the location of the spa, the foundation of the spa as well as the electrical installation of the spa. Installation instructions in the form of a Pre-Delivery Instruction booklet can be obtained from either your CALDERA dealer or online.
DO:

• Know which water treatment system you will be using and make sure you have necessary chemicals available. Read all of the instructions that come with the system.

• Have 5-way Test Strips Available.

• Have pH/Alkalinity Up & Down available.

•  Know the “Hardness” of your water, contact your dealer to help you with this information. See Water Quality and Maintenance for more information.
  IMPORTANT: Watkins Wellness does not recommend that the spa be filled with “softened” water, as this may damage the spa’s equipment.

• Purchase the Clean Screen® pre-filter to remove unwanted contaminants from the tap water. This is recommended, not required.
  DON’T:

• Power up the spa until it has been filled with water! Power to the spa automatically activates critical components within the spa, such as controls, heater, circulation pump, and other systems. If power is supplied to these components prior to the spa being filled, the components will be damaged, and this may result in a non-warranty component failure.

• Fill the spa with hot water or cold water with cold water temperature below 50º F (10º C)! Tripping of the high-limit thermostat may result causing your spa to stop functioning.

• Use your spa after filling until all of the steps listed below START-UP are completed!

• Add chlorine if treating your spa with polyhexamethylene biguanide (Biguanide, PHMB, eg. BaquaSpa® ) sanitizer.

START-UP
Your CALDERA spa has been thoroughly tested during the manufacturing process to ensure reliability and long-term customer satisfaction. A small amount of water may have remained in the plumbing after testing and, as a result, may have spotted the spa shell
or the spa siding prior to delivery. Before filling the spa, wipe the spa shell clean with a soft rag. The following instructions must be read and followed exactly to ensure a successful start-up or refill.
CAUTIONS

• Do NOT fill the spa with hot water, as tripping of the high-limit thermostat may result.
• DO NOT CONNECT POWER TO AN EMPTY SPA. Power to the spa automatically activates critical components within the spa, such as controls, heater, and other systems. If power is supplied to these components prior to the spa being filled, the components will be damaged, and this may result in a non-warranty component failure.
• DO NOT use your spa after filling until all of the steps listed below are completed.
• DO NOT add chlorine if treating your spa with polyhexamethylene biguanide (Biguanide, PHMB, eg. BaquaSpa® ) sanitizer.
•  Before filling your spa for the first time, remove the equipment compartment door and check to ensure that the unions on either sideof the pump(s) and heater are hand-tight.

Door Removal – see page 28:
a. Remove the 2 screws on the bottom of each corner.
b. Find notches in bottom of panel, place fingers on one side and center notch. Slightly pull on bottom side panel to release 1st clip.
Move over to other side and center notch and pull on bottom to release 2nd clip, then lower and remove panel.

1. CLOSE DRAIN, remove the filter compartment cover, skimmer basket, weir, and filter. Fill your spa through the filter compartment using the CleanScreen pre-filter that attaches to your garden hose.
   The water level of your spa should be maintained at a level one inch above the highest jet in the spa. Reinstall the filter and then the skimmer basket, and weir once the spa is filled.
   IMPORTANT: Watkins Wellness does not recommend that the spa be filled with “softened” water, as this may damage the spa’s equipment.™

2. AFTER THE SPA HAS BEEN FILLED with water and the equipment compartment door is secured, power must be applied to the spa.
   • 115 volt models: Connect the GFCI to the waterproof receptacle and push the RESET button on the GFCI.
   • 230 volt models: Open the door of the electrical subpanel, reset the GFCI breaker, verify the system is primed. Close and secure the subpanel door.

3. TO CHECK THE OPERATION OF THE JET SYSTEM and to purge any remaining air from the heating system:
   • Push the JETS button 3 times (twice for TARINO, CELIO & AVENTINE models) to run pump(s) on high speed, run for one minute.
   Weak or surging jets are an indication of a low water level condition or clogged filter cartridges.
   IMPORTANT: Be sure the air Lever (see illustration in Spa Features section) is open by turning clockwise until it stops. Combination jet faces can be turned to completely shut off jet flow, these jets should be open as well.

4. USING A TEST STRIP AND APPLICABLE CHEMICALS, adjust Total Alkalinity (TA) to 80 ppm, Calcium Hardness (CH) to 100 ppm, then spa water pH to between 7.2 and 7.8. Theseprocedures are listed in the “Water Quality and Maintenance” section.
   IMPORTANT: Always add spa water chemicals directly into the filter compartment with the jet pump on high speed for at least ten minutes. Adjusting the Total Alkalinity (TA) as the first step is important, as out-of-balance TA will affect your ability to adjust the pH correctly and will prevent the sanitizer from operating effectively.

5. IF USING FROG: Dial the mineral cartridge to setting 6 and snap into the top space of the cartridge holder. Dial the bromine cartridge to setting 3 and snap into the bottom space of the cartridge holder.
   For @ease Chlorine, see table on page 4 of @ease Operating Instructions.

6. IF NOT USING @ease SMARTCHLOR SYSTEM, SUPERCHLORINATE THE SPA WATER by adding 1½ teaspoons of chlorine (sodium dichlor) per 250 gallons (950 liters) of spa water, then activate the Clean cycle by pressing the soft button next to CLEAN on the home screen.

7. IF NOT USING @ease SMARTCHLOR SYSTEM, TEST THE SPA WATER FOR CHLORINE RESIDUAL. If the residual is between 3 and 5 ppm on the test strips, go on to the next step. If the residual is less than 3 ppm, activate the Clean cycle, and then retest, add more chlorine as necessary.
   IMPORTANT: For Canada, if you are only using the FROG bromine cartridge, your bromine levels should be between 3.0 – 5.0 ppm.
   WARNING: High sanitizer levels can cause discomfort to the user’s eyes, lungs and skin. Always allow the sanitizer level to fall to the recommended range before using the spa.
   IMPORTANT: Each time the spa is filled with water, you must remove and reinstall the FROG cap, even if you are not replacing the cartridge, in order to properly prime the jet pumps.

8. RECHECK the Total Alkalinity (TA) 40 – 120 ppm, Calcium Hardness (CH) 75 – 150 ppm, then spa water pH at between 7.2 and 7.8.
   OPERATION NOTE: Make sure you adjust your Total Alkalinity and pH correctly, this will affect the sanitizers effectiveness.

The spa is ready for use when the spa water has circulated and the bromine level remains between 1 and 2 ppm or chlorine level remains between 0.5 and 1 ppm with @ease, or 3-5 ppm with regular chlorine.
OPERATION NOTE: For proper water circulation during the tenminute Clean cycle the following steps should be performed.

• Place the diverter valve in the middle (split flow) position
• Place air control levers in OFF position by rotating clockwise

PRIMING THE PUMP(S)
Upon filling or refilling the spa, if a pump is operating and water is not flowing from any of its jets, the pump may not be properly primed. To correct, refer to the illustration below and perform the following procedures:

• Turn off power to the spa at the breaker and remove the equipment compartment door.
• Loosen the union on the top of the pump(s) to allow the air to escape. When water is present, hand-tighten the union.
• Turn power back on, activate the pump and check to make sure union is tight enough to keep it from leaking. Re-install equipment door.

NOTE: Equipment compartment illustrated below will vary depending on spa model. IMPORTANT
THE DRAIN CAP AND UNION FITTINGS IN THE EQUIPMENT COMPARTMENT MAY LOOSEN DURING TRANSPORTATION. TO AVOID LEAKS, PLEASE CHECK TO MAKE SURE THESE ARE HAND-TIGHT PRIOR TO FILLING YOUR SPA.

SLEEP MODE
The Sleep Mode operation is a feature that minimizes pump operation during quiet evening hours. For example, if Filter Cycle 1 (F1) is set to activate at 8:00 a.m., by default, Filter Cycle 2 (F2) will activate at 8:00 p.m. (12 hours later). During 8:00 p.m. to 8:00 a.m., if the spa should call for heat, the pump and heater will activate to heat the spa under normal temperature demand. However, when in Sleep Mode, should the spa call for heat, the pump and heater will be suspended after Filter Cycle 2 (F2) until the activation of Filter Cycle 1 (F1), at 8:00 a.m. to minimize pump activation during quiet evening hours.
Important: Power-up of the spa starts the F1 sequence. In order for the sleep mode to work in the evening hours, the spa must be powered up in the early morning hours. The Sleep Mode will always be active the 6-12 hours between the end of (F2) and the beginning of (F1) depending on how the filter cycle program is set.
Note: If temperature drops below 80º F (27º C), heater will automatically activate to prevent spa from freezing.

Water Quality and Maintenance

BASIC INFORMATION
It’s important to have clean water. Water maintenance is one of the leastunderstood, yet most important, areas of spa ownership. Your dealer can guide you through the process of achieving and maintaining perfectwater in your spa, given your local conditions.
IMPORTANT: Water Terminology can be found at the end of this section.

• Always read & refer to the owner’s manual for complete information.
• Test your water with a test strip once a week, or each time the spa is used.
• Add chemicals in frequent small amounts to prevent overdosing the spa.
• Use the spa only when the chlorine level is between 0.5 – 1.0 ppm with @ease system, or 1 – 5 ppm with regular chlorine or manually add chlorine as needed.
• It is the spa owner’s responsibility to prevent over or under chlorination.

IMPORTANT: Remember to change your water every three to four months.
Check with your CALDERA dealer to determine if water in your region has unique qualities – such as high metal or mineral content – that should be addressed.
Your program will depend on your water’s mineral content, how often you use your spa, and how many people use it.
WATER QUALITY CHART

Maintaining the water quality and the cleanliness of the filter in your spa is your responsibility. Keeping the spa water balanced prolongs the life of the spa components and will make the water more comfortable. Your dealer can guide you through the process of achieving and maintaining perfect water in your spa, given your local conditions. Your program will depend on your water’s mineral content, how often you use your spa, and how many people use it. Watkins Wellness has developed several water care systems and products to simplify water care which are available from authorized CALDERA dealers.

CHEMICAL SAFETY
When using chemicals, read the labels carefully and follow directions precisely. Though chemicals protect you and your spa when used correctly, they can be hazardous in concentrated form. Always observe the following guidelines:

• Allow only a responsible person to handle spa chemicals. Keep them out of the reach of children.
• Accurately measure the exact quantities specified, never more. Do not overdose your spa.
• Handle all containers with care. Store in a cool, dry, well ventilated place.
• Always keep chemical containers closed when not in use. Replace caps on their proper containers.
• Don’t inhale fumes, or allow chemicals to come in contact with your eyes, nose, or mouth. Wash your hands immediately after use.
• Follow the emergency advice on the product label in case of accidental contact, or if the chemical is swallowed. Call a doctor or the local Poison Control Center. If a doctor is needed, take the product container along with you so that the substance can be identified.
• Don’t let chemicals get on surrounding surfaces or landscaping. Don’t use a vacuum cleaner to clean up chemical spills.
• Never smoke around chemicals. Some fumes can be highly flammable.
• Don’t store any chemicals in the spa equipment compartment.

HOW TO ADD CHEMICALS TO THE WATER
IMPORTANT: All spa water chemicals (other than FROG cartridges), must always be added directly into or in front of the filter compartment while a jet pump is running, and it must run for a minimum of ten minutes.
To Administer Spa Water Chemicals:

1. Fold back the cover. Carefully remove and set aside the filter compartment cover.

2. On your Control Panel:
   Push the MODE ( ) button several times until the CLEAN menu is displayed. Press the (+) button to activate the CLEAN mode feature.

3. Carefully measure the recommended amount of chemical and slowly pour it into the filter compartment. Use care not to splash chemicals on your hands, in your eyes, on the spa shell surface, or on the spa cabinet.

4. Replace the filter compartment cover. After ten minutes, the jet pump will automatically shut off to complete the procedure. Close and secure the cover.

DANGER: Risk of Drowning: Never leave an open spa unattended!
IMPORTANT: After administering a super chlorination treatment or non- chlorine shock to your spa, leave the cover open for a minimum of 20 minutes to allow the oxidizer gas to vent. A high concentration of trapped oxidizer gas which may exist as a result of the shock treatment (not daily sanitation) may eventually cause discoloration or vinyl degradation to the bottom of the cover. This type of damage is considered chemical abuse and is not covered under the terms of the limited warranty.
FUNDAMENTALS OF WATER MAINTENANCE

• Testing: Test the water weekly or each time the spa is used with convenient 5-way test strips or more accurate liquid/tablet reagent test kit per instructions. Critical parameters: sanitizer level, pH, Calcium Hardness (CH), and Total Alkalinity (TA). Store test equipment in a dark,cool, dry place to maintain potency.

• Water Filtration: The filtration used in CALDERA spas helps keep water clean by circulating sanitizer and removing waste from the spa.
  Regularly inspect and clean filters for peak performance.

• Chemical Balance/pH Control: It is important to adjust the primary water parameters (Total Alkalinity, Calcium hardness, pH) into the recommended ranges so that they are stabilized or balanced. Balance the water chemistry every time you fill the spa with new water and then during the life of that body of water. Keeping the water in balance prevents damage by holding the pH in a safe range and preventing calcium scale formation on spa equipment.
  A low pH can damage metal components whereas a high pH can cause high levels of calcium to form scale. Your dealer should provide a detailedwater chemistry orientation soon after your new spa is filled for the very first time.

• The following three water components must be kept in balance to avoid damage to the spa. Do balance these components in the order they are listed here as each will help you balance the next using a minimum amount of chemicals.
  1. Calcium Hardness (CH) – CH is the measure of the amount of dissolved calcium in the water. Low levels can make the water corrosive and high levels cause scale formation of spa components. The recommended CH reading is between 75 – 150 ppm. If the CH level is too high, lower it with the VANISHING ACT calcium remover per instructions. Once in balance, the CH reading normally remains stable until new water is added. Great care must be taken when filling the spa from a water softener to ensure that the calcium remains in balance and avoid damage to the spa.
  2. Total Alkalinity (TA) – TA is a measure of the water’s ability to resist changes of pH or buffer capacity. A low TA allows the pH to fluctuate easily. The recommended TA reading is between 40 – 120 ppm. To raise the TA, use pH/Alkalinity Up (sodium hydrogen carbonate). To lower the TA, use pH/Alkalinity Down (sodium bisulfate). Once the TA is balanced, it normally remains stable until the next drain/refill. We recommend you check the TA reading once per month. Raising/lowering the TA may cause the pH readings to fluctuate widely. Ignore the pH readings on the test strip while you are balancing the TA.
  3. pH – The pH is the measure of the acidity and alkalinity. Maintaining the proper pH level will optimize the effectiveness of the sanitizer, preventing damage to the spa and physical discomfort for spa users. A low pH dissipates sanitizer, causes corrosion, and irritates spa users. A high pH level will neutralize sanitizer, promote scaling and cloud water. The recommended pH reading is between 7.2 – 7.8. To lower the pH level, use pH/Alkalinity Down (sodium bisulfate). To raise the pH level, use pH/Alkalinity Up (sodium carbonate).

• Water Conditioners: Spa fill water varies from location to location and user to user, therefore it is important to consult with your dealer for an appropriate program.
  a. VANISHING ACT – High levels of calcium and some minerals can be removed from the water with the single use VANISHING ACT. High calcium levels can cause scale formation on the spa equipment and shell.
  b. CLEAN SCREEN pre-filter –The CLEAN SCREEN pre-flter should be used at every fill and top-off to remove contaminants from the fill water, especially iron, copper, and manganese. Many water sources including well water contain high concentrations of minerals that can cause staining of the shell and plastics.
  c. Stain and Scale control – For water high in calcium and minerals, it may be necessary to use an anti-scalant like Stain and Scale control. As water evaporates from your spa and new water is added, the amount of dissolved minerals like calcium, copper, iron, and manganese will increase. (Minimize evaporation by keeping the cover on the spa whenever possible.) High iron or copper content in the water may produce green or brown stains on the spa.
  d. Foam Inhibitors – Soap is introduced into the spa water from users’ bodies and swimming apparel and can cause the spa water to foam when the jets are used. Low levels of calcium hardness (soft water) can increase foaming. Although ozone can oxidize soap residual, it may become necessary to add Foam Inhibitors to suppress the foam. Excessive soap in the water may require a water change to resolve.

• Oxidizers: Ozone and Monopersulfate (MPS) are oxidizers used to prevent the buildup of contaminants, maximize sanitizer efficiency, minimize combined chlorine, and improve water clarity. They are to be used in conjunction with EPA registered sanitizers. The high output ozone system uses a Corona Discharge technology to produce a high concentration of ozone which is injected into the spa water 24 hours per day. Chlorine-Free Oxidizer, Monopersulfate (MPS) is a granular oxidizing chemical.

• Sanitizers: Maintaining the recommended residual level of an EPA registered sanitizer at all times will decrease the occurrence of unsafe bacteria and viruses in your spa water. The recommended Free Available Chlorine (FAC), the amount of available chlorine sanitizer, is 3.0 – 5.0 ppm or 0.5 – 1.0 ppm with @ease SmartChlor Chlorine System. A low FAC can allow bacteria and viruses to grow rapidly in the warm water, and a high FAC can cause discomfort to the user’s eyes, lungs, and skin. Each sanitizer carries its own instructions regarding how much to use and when to add it to the spa water.
  Consult your dealer for their recommendations and instructions on proper sanitizing of the spa.
  Watkins recommends the following sanitizers:

• FROG sanitizing systems (mineral and bromine) or (mineral and chlorine)

Watkins also approves the following sanitizers:

• Sodium Dichloro-s-Triazinetrione (sodium dichlor or chlorine)
• Biguanide

IMPORTANT: DO NOT use tri-chlor chlorine, bromo-chloro-dimethyl- hydantoin (BCDMH), or any type of compressed bromine or chlorine, acid or any type of sanitizer which is not recommended by Watkins Wellness and will void the warranty.
FROG WATER CARE SYSTEM
The FROG In-Line Water Care system is comprised of the following products:
THE FROG MINERAL CARTRIDGE. This cartridge introduces minerals into the spa water, inhibiting bacteria growth.
THE FROG @ease SMARTCHLOR CARTRIDGE. The recommended chlorine sanitizer that works in conjunction with the FROG Mineral cartridge to maintain softer, crystal clear water with up to 75% less chlorine than ordinary dichlor systems.
THE FROG BROMINE CARTRIDGE (BCDMH). The recommended sanitizer for those users who prefer bromine as an alternative to chlorine.
It is important that in addition to regularly testing and balancing your spa water, a weekly “shock treatment” is required. The shock treatment quickly destroys any remaining contaminants while revitalizing the bromine in the water.
To weekly “shock treat” your spa, we recommend that you use either MPS Plus or sodium dichlor (chlorine). Sodium dichlor may be a more appropriate weekly shock for those users that experience heavy bather load conditions.
The following optional products can be used in conjunction with the FROG Water Care system:
MPS PLUS NON-CHLORINE SHOCK (MPS/Monopersulfate) is an oxidizing chemical used to prevent the buildup of contaminants, maximize sanitizer efficiency, and improve water clarity. When used in conjunction with the FROG system it oxidizes particulates in the spa water.
IMPORTANT NOTE: MPS Plus is an oxidizer, not a sanitizer. CORONA DISCHARGE (CD) OZONE is a high output ozone system and is the only ozone purification system approved for installation in your CALDERA Spa. The ozone system utilizes CD technology to produce a higher concentration of ozone than is produced by a competing chip style CD or ultraviolet light ozone systems.
NOTE: Refer to the Start-Up instructions on page 2 of your FROG @ease SmartChlor owner’s manual, (for FROG Bromine see page 4).
The owner’s manual can be found with your FROG starter kit.
It is important to follow the recommended application and maintenance programs outlined for each product’s use. If the spa is being used over an extended period or time, such as a whole afternoon or evening, additional sanitizer will be needed.
NOTE: The FROG Mineral Cartridge or @ease Chlorine Cartridge are not approved for use in Canada.
NOTE: For Canada, if you are only using the bromine cartridge, your bromine levels should be between 3.0 – 5.0 ppm.

FROG CARTRIDGE REPLACEMENT INSTRUCTIONS
The FROG bromine or @ease Chlorine cartridge should be replaced every 2-4 weeks, depending on User Load. The FROG mineral cartridge should be replaced every 4 months. When replacing the mineral cartridge, it is highly recommended that the spa be drained and refilled at the same time. After refilling the spa with water, balance the Total Alkalinity (TA), Calcium Hardness (CH) and pH to the recommended levels. Shock the spa by adding MPS Plus non-chlorine shock shock or sodium dichlor (chlorine).

To replace FROG cartridges, follow these steps:

1. Turn off power to the spa.

2. Unscrew FROG cap on top edge of spa.

3. Turn handle counter-clockwise.

4. Lift cartridge holder up and out of spa.

5. Remove and discard old cartridges.

6. Turn top cap of new Mineral cartridge to setting #6 (evaluate water in 1 week and adjust as necessary).

7. Turn top cap of new bromine cartridge to setting #6 (measure bromine with bromine Test Strip in 1 week and adjust as necessary).

8. For @ease chlorine cartridge setting, see table below:
   @ease SmartChlor| VACANZA Series Models
   ---|---
   AVENTINE| ALL MODELS EXCEPT AVENTINE
   Setting| 1| 2

9. Snap bromine or @ease Chlorine cartridge into the bottom of holder and snap mineral cartridge into the top.
   IMPORTANT: It is important that the bromine cartridge is on the bottom; otherwise, the bromine cartridge could dispense prematurely.

10. Reinstall cartridge holder into spa, push down, and twist clockwise.

11. Replace FROG cap.

12. Reconnect power to the spa.

IMPORTANT NOTE: Adjust bromine cartridge setting down by one setting each day until a residual of 1.0 – 2.0 ppm level of bromine is established.
WARNING: High sanitizer levels can cause discomfort to the user’s eyes, lungs and skin. Always allow the sanitizer level to fall to the recommended range before using the spa.

THE CALDERA SPA WATER MAINTENANCE PROGRAM
FILLING THE SPA WITH WATER
Use the CLEAN SCREEN pre-filter to remove unwanted contaminants such as rust, dirt, detergents, and algae from the fill water. Dissolved metals, copper, iron, and manganese are also removed. Instructions are included with the CLEAN SCREEN pre-filter. Always fill the spa through the filter compartment. Do not fill your spa using water from a swimming pool as pool chemicals are very different from those used in a spa and can damage your spa.

ADDING CHEMICALS TO THE WATER
All spa water chemicals, including granulated dichlor, MPS, granulated pH increaser or decreaser, granulated total alkalinity increaser, liquid stain and scale inhibitor, and liquid defoamer must always be added directly into the filter compartment while the jet pump is running in its high speed mode, and it must run for a minimum of ten minutes with the cover off. Use the Clean button/feature to ensure that the chemicals are properly mixed when adding.
BUILDING A SANITIZER ROUTINE
During the first month of ownership, measure the sanitizer residual daily in order to establish a baseline of sanitizer needed vs. spa usage.
Sanitizer needed is the amount of Free Available Chlorine needed to accommodate the number of users and their combined usage time. For example, two spa users for twenty minutes every day creates regular demand on the sanitizer that is used to determine how much sanitizer to add in order to maintain the proper residual. If the usage pattern increases dramatically with invited guests, the amount and frequency of sanitizer required increases dramatically.
PERFORMING SUPER CHLORINATIONNON-CHLORINE SHOCK TREATMENT
A weekly or monthly super chlorination (1.5 tsp dichlor/250 gal (950 lit)) or shock (4tbs mps/250 gal (950 liters)) may be required of your chosen sanitation program. Increasing chlorine to 5 ppm for 24-48 hoursremoves excess waste and chloramines from the water. Sodium dichloris 6x stronger than MPS and may be a more appropriate for those usersthat experience heavy bather load conditions. Operate all jets and leavethe cover open for a minimum of 20 minutes to allow the oxidizer gasto vent to prevent damage and discoloration to the cover and pillowsafter administering a super chlorination or shock to your spa. This typeof damage is considered chemical abuse and is not covered under theterms of the limited warranty.
IMPORTANT: Always allow the Free Available Chlorine to fall below 5 ppm before using your spa.
DANGER: Never leave an open spa unattended, especially if there are children present!
MANUAL CHLORINE (SODIUM DICHLOR)
Watkins Wellness recommends the use of Concentrated Chlorinating Granules (sodium dichlor) for sanitizing the water. Sodium dichlor is preferred because it is totally soluble, dissolves quickly, and is nearly pH neutral. The recommended Free Available Chlorine (FAC), the amount of available chlorine sanitize the spa, 1.0-5.0 ppm.
If the FAC is too low: Increase the FAC by adding granulated sodium dichlor.
If the FAC is too high: Allow time to pass and the FAC level will naturally drop over time.
If the spa smells of chlorine: super chlorinate or shock the spa FAC chlorine does not have an odor whereas combined spent chlorine (chloramines) has a strong chlorine odor that can be eliminated by shocking the water.
IMPORTANT: There are several forms of stabilized chlorine available for use in spas and swimming pools. It is extremely important to choose one specifically designed for spas. Use of an incorrect product such as tri-chlor which has a very low pH (2.6) and dissolves too quickly in hot water, results in extremely high levels of chlorine that WILL cause damage to your spa. Use of a liquid or compressed bromine/chlorine or unapproved sanitizer WILL damage your spa and is specifically not covered under the terms of the limited warranty.

DO:

• Add all chemicals slowly into the filter compartment with the jet pump operating for ten minutes.
• Use special care if using baking soda to clean either the interior or exterior plastic surfaces.

IMPORTANT: Watkins Wellness DOES NOT recommend the use of any floating chemical dispenser. Damage to the spa shell or components caused by a floating chemical dispenser is specifically not covered under the terms of the limited warranty. Floating dispensers can become trapped in one area and cause an over-sanitization or release large chunks of sanitizer that very quickly chemically burn the shell and cover.

DON’T:

• Use compressed sanitizers.
• Use a floater type sanitization system as a low or no maintenance solution to your spa maintenance program.
• Use a sanitizer which is not designed for spas.
• Use swimming pool (muriatic) acid to lower pH.
• Broadcast or sprinkle the chemicals onto the water surface. This method may cause chemically-induced spa surface blistering (chemical abuse).

OZONE MAINTENANCE
If Reduced or no ozone bubbles are coming from the heater return (clogged ozone injector) or no ozone, clean the injector:
DANGER: Nitric acid accumulates in the air lines of the ozonator and injector, and will cause severe chemical burns if direct skin contact is made. Always wear protective gloves, glasses and clothing when working on the ozonator or injector lines. To prevent inhalation or ingestion of the nitric acid, DO NOT blow or inhale with your mouth to any of the adapters, fittings or tubing of the ozonator or injector air lines.

1. Place 16 ounces (.5 liters) of white vinegar into a cup or bucket.
2. Carefully loosen the long tubing attached to the bottom of the ozonator, located in the equipment compartment.
3. Place the end of the tubing into the vinegar, making certain that the end of the tubing sits at the bottom of the container.
4. Run the spa until all 16 ounces (.5 liters) of the vinegar are gone. This should allow an ample flow of vinegar to be run through the injector and clear the blockage.
5. Reinstall the tubing to the bottom of the ozonator.

Water chemistry damage is not covered by the warranty. The chemical levels and water quality in the spa are under your direct control.
With proper basic care, the spa will provide many years of hot water relaxation. If you are unsure about any chemical or its usage in the spa, contact your Authorized Dealer, or Watkins Wellness.
If you are unsure about any chemical or its usage in the spa, contact your Authorized Dealer, or Watkins Wellness.
VACATION WATER CARE INSTRUCTIONS
If you plan to be away from home, follow these instructions to ensure that the water quality of your spa is maintained:

SHORT TIME PERIODS (3-5 DAYS)

1. Adjust the pH by following the instructions outlined in the Water Quality and Maintenance section.
2. Sanitize the water by following the shock procedures also listed in the Water Quality and Maintenance section.
3. Lock your cover in place using the coverlocks.
4. Upon your return, sanitize the water by following the shock procedures, and balance the pH.

LONG TIME PERIODS (5-14 DAYS)
Prior to leaving:

1. At least one day before you leave, set the temperature to its lowest level. This setting should represent an approximate water temperature of 80°F (27°C)
   IMPORTANT: Spa water oxidizers such as sodium dichlor (chlorine) maintain their level of effectiveness substantially longer in warm water 80°F (27°C) than in hot water 101°F to 104°F (38°C – 40°C).

2. Adjust the pH as required. Sanitize the water by following the shock procedures.
   Upon your return:

3. Sanitize the water by following the shock procedures. Return the set temperature to its original setting. The spa water will be safe for you to use once the Free Available Chlorine residual level has dropped below 5.0 ppm.

IMPORTANT: If you will not be using your spa for an extended period of time (in excess of 14 days) and an outside maintenance service (or neighbor) is not available to assist with the water maintenance, draining or winterizing of the spa is recommended.

SUPPLEMENTAL WATER MAINTENANCE
Proper water sanitation and mineral balance (pH control) are absolutely essential for a complete spa water maintenance program. Here are two other popular water additives that are optional:

Mineral Deposit Inhibitors
As water evaporates from your spa and new water is added, the amount of dissolved minerals will increase. (Minimize evaporation by keeping the cover on the spa whenever possible.) The spa water may eventually become “hard” (Calcium Hardness too high) enough to damage the heater by calcifying its surface. Proper pH control can minimize this.
Normal soap build-up will require water replacement regularly enough that mineral deposits normally are not a problem.
Occasionally, high iron or copper content in the water may produce green or brown stains on the spa. A stain and scale inhibitor may help to reduce these metals.
IMPORTANT: Well water may contain high concentrations of minerals.
The use of a low water volume, extra-fine pore water filter (in-line prefilter such as the CLEAN SCREEN pre-filter) will help to remove many of the larger particles during the filling of the spa. In-line pre-filters can be purchased at your local CALDERA dealer.

Foam Inhibitors
Spa water requires changing due to the buildup of soap in the water.
Typically, soap will cause the spa water to foam when the jets are used.
Soap is introduced into the spa water from two sources: users’ bodies, which retain a soap residual after showering, and swimming apparel, which retains soap after washing.
Foam inhibitors can suppress foam, but cannot remove soap from the water. Soap is very difficult to remove from the water because soap is not oxidized by any chemical added to the spa. Only ozone can oxidize soap. Eventually the soap build-up in the water will be concentrated, resulting in an unclean feeling on the bather’s skin, which is impossible to remedy. When this occurs, it’s time to drain and refill the spa.
Depending on the soap input, the water should last about four months before needing to be drained.

WATER TERMINOLOGY
The following chemical terms are used in this Water Quality and Maintenance section. Understanding their meaning will help you to better understand the water maintenance process.
Bromamines: Compounds formed when bromine combines with nitrogen from body oils, urine, perspiration, etc. Unlike chloramines, bromamines have no pungent odor, and are effective sanitizers.
Bromine: A halogen sanitizer (in the same chemical family as chlorine).
Bromine is commonly used in stick, tablet, or granular form.
Calcium Hardness: The amount of dissolved calcium in the spa water.
This should be approximately 75 -150 ppm. High levels of calcium can cause cloudy water and scaling. Low levels can cause harm to the spa equipment.
Chloramines: Compounds formed when chlorine combines with nitrogen from body oils, urine, perspiration, etc. Chloramines can cause eye irritation as well as having a strong odor. Unlike bromamines, chloramines are weaker, slower sanitizers.
Chlorine: An efficient sanitizing chemical for spas. Watkins Wellness recommends the use of sodium dichlor-type granulated chlorine. This type is preferred because it is totally soluble and nearly pH neutral.
Chlorine (or Bromine) Residual: The amount of chlorine or bromine remaining after chlorine or bromine demand has been satisfied. The residual is, therefore, the amount of sanitizer which is chemically available to kill bacteria, viruses and algae.
Corrosion: The gradual wearing away of metal and plastic spa parts, usually caused by chemical action. Generally, corrosion is caused by low pH or by water with levels of TA, CH, pH or sanitizer which are outside the recommended ranges.
Halogen: Any one of these five elements: fluorine, chlorine, bromine, iodine, and astatine.
MPS: Monopersulfate is the non-chlorine oxidizer used with the FRESHWATER Ag+ silver ion purification system. Not a sanitizer.
Nitric Acid: The formulation of nitric acid, a highly corrosive chemical, is a byproduct of the ozone generating process. Nitric acid is produced in very small quantities and is readily dissolved in the water stream with ozone.
Oxidizer: The use of an oxidizing chemical is to prevent the buildup of contaminants, maximize sanitizer efficiency, minimize combined chlorine and improve water clarity. See MPS and Ozone.
Ozone: Ozone is a powerful oxidizing agent which is produced in nature and artificially by man. Ozone forms no byproducts, oxidizes chloramines, and will not alter the water’s pH.
pH: The measure of the spa water’s acidity and alkalinity. The recommended pH for the spa water is 7.2 to 7.8. Below 7.0 (considered neutral), the spa water is too acidic and can damage the heating system.
Above 7.8, the water is too alkaline and can result in cloudy water, and scale formation on the shell and heater.
ppm: The abbreviation of “parts per million”, the standard measurement of chemical concentration in water. Identical to mg/l (milligrams per liter).
Reagent: A chemical material in liquid, powder, or tablet form for use in chemical testing.
Sanitizer: Sanitizers are added and maintained at recommended residuals to protect bathers against pathogenic organisms which can cause disease and infection in spa water.
Scale: Rough calcium-bearing deposits that can coat spa surfaces, heaters, plumbing lines, and clog filters. Generally, scaling is caused by mineral content combined with high pH. Additionally, scale forms more readily at higher water temperatures.
Sodium Hypochlorite (Liquid chlorine/bleach): Unstabilized (without cyanuric acid) chlorine in liquid form. Very effective however it has a very high pH and requires acid adjustment to maintain water parameters.
Never add acid directly to chlorine.
Super-Chlorination: Also known as “shock treatment.” SuperChlorination is a process of adding significant doses of a quick dissolving sanitizer (“dichlor” is recommended) to oxidize non-filterable organic waste and to remove chloramines and bromamines.
Total Alkalinity (TA): The amount of bicarbonates, carbonates, and hydroxides present in spa water. Proper total alkalinity is important for pH control. If the TA is too high, the pH is difficult to adjust. If the TA is too low, the pH will be difficult to hold at the proper level. The desired range of TA in spa water is 40 to 120 ppm.

Spa Care and Maintenance

Your CALDERA spa is manufactured from the highest quality, most durable materials available. Even so, the spa care and maintenance program you develop will ultimately determine how long your spa, andits individual components, will last. Regular maintenance and followingthe advice in this section will help you to protect your investment.
DRAIN & REFILL INSTRUCTIONS
IMPORTANT: It is NOT recommended to refill your spa when the ambient temperature goes below 50°F (10°C).

1. Disconnect the spa from the power supply by tripping both of the GFCI breakers located in the subpanel. Unplug power cord for 115Vmodels.

2. Locate the drain valve for the spa (lower front of the spa) and remove the drain cap. Attach the inlet of a garden hose to the drain valve and route the outlet of the hose to an appropriate draining area. Spa water with a high sanitizer level may harm plants and grass.

3. Open the drain valve by turning the knob. The spa will drain by gravitational flow.
   IMPORTANT: All Caldera spa models will drain to the bottom of thesuction fitting, use vacuum side of shop vac to remove remaining water. Any water remaining within the plumbing or equipment after draining will only need to be removed if the spa is being winterized.

4. When empty, inspect the spa shell and clean as required. (Follow the Care of the Exterior instructions.)

5. Close the drain valve and reinstall the drain cap.

6. Install new filter or clean existing with filter cleaner.

7. Refill the spa through the filter compartment using the CLEAN SCREEN pre-filter.
   IMPORTANT: Refill water temperature must be between 50° – 70°F (10° – 21°C) to avoid high-limit tripping.

8. Follow the Quick Start-Up instructions on page 8.

COLD WATER REFILL
Should it be necessary to drain and refill your spa in temperatures below 50° F (10° C), the spa may go into a High Limit Protection mode (causing your spa to stop functioning) if the tap water is below 50°F (10°C). Blending warm water with the cold tap water so it exceeds 50°F (10°C) during the refilling process will prevent the spa from going into the High Limit Protection mode if that is an option for you.
PREVENTION OF FREEZING
Your spa has been designed and engineered for year-round use in any climate. In some areas, extremely cold temperatures below 10°F (-12°C) combined with strong wind, may cause partial freezing of the jet pump, even though the water inside the spa remains at the selected temperature. The energy efficiency of the spa may also decrease during these cold periods, as the heater will cycle more frequently. As an additional precaution against partial freezing of some of the components, the equipment compartment can be insulated with an insulating kit (available from your local dealer). This insulating kit will also help to maximize the spa’s energy efficiency.
NOTE: When warmer weather returns (approx. 60-70°F (16°-21°C)), the insulating kit must be removed to prevent overheating of the jet pump.

WINTERIZING YOUR SPA
If you leave the spa unused for a long period of time in severely cold weather, you should drain the spa and winterize it to avoid accidental freezing due to a power or equipment failure.
DANGER: Use only Propylene Glycol as your anti-freeze (available at most RV or marine supply stores). This is non-toxic. Never use an automobile anti- freeze (Ethylene Glycol) since it is toxic!
WARNING: Failure to follow these instructions correctly can lead to freeze damage not covered by warranty. It is strongly recommended that you contact your local CALDERA dealer to perform this service

1. Drain your spa following the Drain & Refill Instructions. Open waterfall valve.

2. Remove the filter cartridge, clean and store in a dry place.
   IMPORTANT: These additional instructions must be utilized when draining and winterizing your spa in climates where the temperature falls below 32°F (0°C). A 5 gallon (19 liters) combination (vacuum/blower) wet/dry shop vac must be used to
   effectively remove water that is trapped inside the plumbing lines.

3. Attach the vacuum hose to the vacuum side of the shop vac. Vacuum all openings and orifices as follows:
   a. Jet openings: start with the jets at the top and move downward (if suction is coming from another jet, block off the other jet using a large rag this will help pull out the water that is trapped deeper inside the main line).
   b. Filter suction fittings and filter compartment.
   c. Main drain outlet (it may be necessary to cover the drain grate tightly with a rag when vacuuming the main drain to ensure water is drawn completely from the internal plumbing system).

4. Thoroughly dry the spa shell with a clean towel.

5. Replace the main drain cap.
   CAUTION: Use only Propylene Glycol as your anti-freeze. This is non- toxic. Never use an automobile anti-freeze (Ethylene Glycol) since it is toxic!

6. Using a long-extension funnel, pour anti-freeze into all standpipes, filter suction fittings, jet orifices and water feature orifices. Add enough anti-freeze to ensure adequate protection – in many cases, you will see the liquid in the orifice, or coming out of another location.

7. Close the spa cover and fasten the cover tie downs. Cover the spa cover with two pieces of plywood to evenly distribute the weight of snow and ice. Secure a plastic sheet, or tarp, over the spa cover and plywood.

8. Replace the equipment access door, if removed.

OPENING INSTRUCTIONS:

1. Remove plywood and plastic sheet. Open the spa cover by unfastening the cover tie downs.

2. Follow the Start-up and Refill Procedures in the Operating
   Instructions section of the Owner’s Manual. Do not install filters to prevent them from exposure to the anti-freeze.

3. As part of this process, superchlorinate the spa water by adding three teaspoons of chlorine (sodium dichlor) per 250 gallons (950 liters) of spa water into the filter compartment. This is twice the normal amount of chlorine needed for superclorination. This extra amount of chlorine is needed to destroy the anti-freeze.
   NOTE: A defoamer may be needed to decrease the amount of foam caused by the anti-freeze.

4. Drain your spa to ensure removal of anti-freeze. Do not drain water on grass or plants due to excessive chlorine level.

5. After the spa has completely drained, re-install your filter and follow the Start-up and Refill Procedures in the Operating Instructions section of the Owner’s Manual.

IMPORTANT: Always keep spa covered when not in use, whether it is empty or full.
FILTER SYSTEM
The filter lid on the spa is NOT designed to support heavy weight loads and should not be used as a seat. In extreme cases, the lid could crack and break. This occurrence is considered abuse and is not covered under the warranty.
CALDERA spas are equipped with one filter cartridge, sized to meet the needs of the jet pump system.
At least once a week, check and clean the skimmer basket and weir to ensure proper filter flow. Remove leaves, foreign matter, and debris. It is very important to keep your spa filter cartridge clean and free of particles to ensure proper water flow. A clean filter permits the hydrotherapy system to function properly and also allows more efficient filter cycles.
Depending on how frequently your spa is used, we recommend cleaning the spa filter cartridge every four weeks. If this is not done, the filter may clog and restrict water flow, which causes improper filtration and poor jet performance.
WARNING: To reduce the risk of injury to persons using the spa, DO NOT remove the suction fittings (filter standpipes) located in the filter compartment and do not sit on the filter lid, in extreme cases the lid could crack and break. This occurrence is considered abuse and is not covered under warranty.

FILTER CARTRIDGES REMOVAL & CLEANING (ALL MODELS EXCEPT AVENTINE)

1. Disconnect the spa from the power supply by turning the power to the spa OFF.

2. Remove any floating items from within the filter compartment.

3. Turn the filter retainer handle (located on the top of the filter cartridge) counterclockwise until the retainer can be removed from the filter standpipe.

4. Remove the filter retainer, cover and cartridge.
   SERVICE NOTE: Never remove the filter standpipe when debris is present in the filter compartment. Debris may find its way into the internal plumbing which may result in blockage. NEVER REMOVE SUCTION FITTINGS!

5. Always clean the filter using afilter degreaser, such as Filter Cleaner, to remove mineral and oil build-up.Simply soak the filter in the degreaser according to the package directions, then place the filter on a clean surface and spray until cleanusing a garden  hose. It may be necessary to rotate the filter while spraying to remove any debris lodged between the filter pleats.

6. To reinstall the filter cartridge, reverse the order of steps in which it was removed. Do not overtighten.

WARNING: Do not use the spa with the filter cartridge, or filter standpipe removed!
FILTER CARTRIDGES REMOVAL & CLEANING FOR AVENTINE MODEL

1. Turn the power to the spa OFF, then proceed as follows:
2. Push down slightly and turn filter basket counterclockwise to unlock, then pull the basket and weir out.
3. Carefully pull up the filter cartridge and bring it out of the spa.
4. Rinse cartridge using a garden hose. Rotate and separate filter pleats while spraying water to remove all debris possible. Let the filter dry and then look for calcium deposits (scaling) or an oil film. If you find these, you will need to deep clean your filter cartridge with a “spa filter cleaning” solution to break down and remove mineral deposits and oils.
5. Install filter then replace basket and weir by inserting and rotating clockwise to lock into position.

CARE OF THE SPA PILLOWS
The spa pillows will provide years of comfort if treated with care. They have been positioned above the water level to minimize the bleaching effects of chlorinated water, and other spa water chemicals. To extend their life, whenever the spa shell is being cleaned, the spa pillows should be removed and cleaned. Body oils can be removed with a mild soap and water solution. ALWAYS rinse off the spa pillows thoroughly to remove any soap residue. If the spa is not going to be used for a long period of time (that is during a vacation, or if the spa is winterized), or when the spa water is being super-chlorinated, the spa pillows should be removed until the next spa use.

To remove and replace the spa pillows:

1. Carefully lift one end of the pillow away from the spa shell.

2. Continue lifting one end until all pillow retainers are released from the pillow.
   IMPORTANT: Just pulling the pillow straight up and out of the shell recess will eventually damage the pillow. This abuse is not covered under warranty.

3. To reinstall the spa pillow, carefully bend the pillow slightly to allow one of the pillow retainers to slip into the recess in the back of the pillow.

4. Keeping the pillow slightly bent, slide the other pillow retainer into the recess in the back of the pillow.

5. After all the pillow retainers are in place, press the pillow down into the recess in the spa shell.

CARE OF THE INTERIOR SPA SHELL
Your CALDERA spa has an acrylic shell. Stains and dirt generally will not adhere to your spa’s surface. A soft rag or a nylon scrubber should easily remove most dirt. Most household chemicals are harmful to your spa’s shell (see below for detailed information on cleaning agents).
Always rinse off any spa shell cleaning agent with fresh water.

IMPORTANT:

1. The following products are the ONLY approved cleaning agents for your CALDERA spa shell: plain water, CALDERA Spa Shine, Brillianize® or Soft Scrub® . The use of alcohol or any other household cleaner other than those listed to clean the spa shell
   surface is NOT recommended. DO NOT use any cleaning products containing abrasives or solvents since they may damage the shell surface, specifically: Simple Green® , Windex® or Spa Mitt. NEVER USE HARSH CHEMICALS! Damage to the shell by use of harsh chemicals is not covered under the warranty. Always rinse off any spa shell cleaning agent with fresh water.

2. Iron and copper in the water can stain the spa shell if allowed to go unchecked. Ask your CALDERA dealer about a Stain and Scale Inhibitor to use if your spa has a high concentration of dissolved minerals. (Watkins Wellness recommends Stain & Scale Defense.)

3. Keep all cleaners out of the reach of children and use care when applying.

CARE OF THE ECOTECH CABINET
The ECOTECH cabinet consists of rigid polymers that combine the durability of plastic, with the beauty of wood.
Cleaning your ECOTECH cabinet is as easy as spraying the cabinet with a mild soap and water solution to remove any stains and residue.
COVER CARE
The cover is made with a solution dyed polyester fabric and is an attractive, durable foam insulation product. Monthly cleaning is recommended to maintain its beauty and a longer fabric life.

To clean and condition the polyester cover:

1. Remove and gently lean against a wall or fence. If a cover lifter has been installed keep cover closed and make sure all seams are closed to prevent any soap from entering the spa.
2. With a garden hose, spray the cover to loosen and rinse away dirt or debris.
3. Add four tablespoons of mild soap or mild dishwashing liquid with one gallon (4 liters) of lukewarm water. Clean using a soft bristle brush. Rinse thoroughly with cold water and air dry. IMPORTANT: Do not let the polyester dry with a soap film on it before it can be rinsed clean.
4. Scrub the cover’s perimeter and side flaps. Rinse clean with water.
5. Rinse off the underside of the cover with water only (use no soap), and wipe it clean with a dry rag.

DO:

• Remove snow buildup to avoid breakage of the foam core from the additional weight of the snow.
• Lock cover lock straps to secure the cover when the spa is not in use.

DON’T:

• Drag or lift the spa cover using either the flaps, or the cover lock straps.
• Walk, stand, or sit on the cover.
• Place any metal or heat transferring object on the cover or place any type of plastic tarp or drop cloth over the cover as this may result in a melted foam core, which would not be covered under the warranty.
• Use any lifting mechanisms, chemicals, or cleaners except those recommended by Watkins Wellness, or its Authorized Sales and Service Dealer.

Service Information

GENERAL INFORMATION
Your CALDERA spa has been designed to provide years of troublefree use. As with any appliance, problems may occasionally occur that require the expertise of a qualified service person. Though such simple repairs as resetting a GFCI switch or breaker, high limit thermostat, or pressure switch, or replacing a light bulb may not require a service call, they may indicate that a more serious condition exists. These conditions may require an experienced service person. Before calling for service, please refer to the Troubleshooting Guide.
NOTE: Always retain your original sales receipt for future reference.
GFCI AND HIGH LIMIT THERMOSTAT
If your spa fails to operate at any time, the following items should be checked:

1. Check the power supply to the spa.
2. Check the GFCI (located at the end of the cord in standard models or in the electrical subpanel in 30 or 50 amp converted models) and see if it has tripped. If a GFCI has tripped, reset it. If it will not reset, this may be an indication of a ground fault (short circuit) within the electrical components. Contact an Authorized Service Technician for a complete diagnosis.
3. If, upon checking the GFCI you find it has not tripped, check the house breaker panel and ensure the main breaker for the electrical circuit supplying the spa has not tripped. If it has, this is an indication that either the circuit was overloaded or a ground fault exists between the breaker panel and the spa receptacle. Contact a qualified electrician.
4. If, upon checking the main house breaker, you find no failures, the heater high-limit thermostat should be checked. Tripping of the heater high-limit thermostat is normally a result of one or a combination of any of these problems: 1) blockage within the system plumbing, 2) switch malfunction in the heater circuit, or 3) the low speed mode of the jet pump is not functioning.
5. If the heater high-limit has tripped, the control panel display will display – – – – -. Reset the heater high-limit by allowing the water to cool and disconnecting power to the spa for at least thirty seconds. If the heater high-limit continues to trip, contact an Authorized Service Technician for a complete diagnosis.

If the spa does not function and the GFCI or GFCI breaker and heater high- limit have not tripped, then the problem should be referred to an Authorized Service Technician. Refer to the Troubleshooting Guide for additional service information.
MISCELLANEOUS SERVICE INFORMATION
The jet pump is equipped with an overload cut-off switch, which is designed to protect the pump from overheating. If the pump shuts itself off in a new spa, it is usually the result of one, or a combination of, the following factors:
High Temperature: During the summer months, especially in warmer climates, the ambient temperature contributes to excessively high temperatures within the equipment compartment.
Improper House Wiring: If the spa is not connected to a dedicated circuit, or is connected to an extension cord, or the house wiring is undersized, the pump may starve for voltage and therefore may draw more amperage and generate excessive heat. This will often cause the circuit breaker to trip repeatedly.
IMPORTANT:

1. If the pump is shutting down due to excessive heat, make sure the equipment compartment has adequate ventilation. The air gap at the bottom and the jet pump vent at the bottom left corner must not be blocked. Should your jet pump continue to shut off after short periods of use, contact a qualified service technician.
2. The VACANZA spa is equipped with a safety suction spring valve which will break the prime of the jet pump if both suction fittings are obstructed.

ACTS INVALIDATING WARRANTY
The limited warranty is void if the CALDERA Spa has been subjected to alteration, misuse or abuse, or if any repairs on the spa are attempted by anyone other than an authorized representative of Watkins Wellness.
Alteration is defined as any component or plumbing change, electrical conversion, or the addition of any non-approved sanitation, or water purification device, or heating system which contributes to a component failure, unit failure, or unsafe operating condition. Misuse and abuse shall include any operation of the spa other than in accordance with Watkins Wellness printed instructions, or use of the spa in an application for which it is not designed; specifically: use of the spa in a nonresidential application; damage caused by operation of the spa at water temperatures outside the range of 35°F and 120°F (2°C and 49°C); damage caused by a dirty, clogged, or calcified filter cartridge; damage to the spa surface caused by the use of Tri-Chloro Chlorine, BCDMH, chemical tablets in a floater, acid, or any other spa chemicals, or spa surface cleaners which are not recommended by Watkins Wellness; damage caused by allowing undissolved spa sanitizing chemicals to lie on the spa surface (no spa surface material can withstand this kind of abuse); damage to components or spa surface caused by improper water chemistry maintenance; and damage to the spa surface caused by leaving the spa uncovered while empty of water and in direct exposure to sunlight (this may cause solar heating distress in warm weather regions). These are considered abuses and may invalidate this warranty.
Operation of the spa DOES NOT mean “use” of the spa! Watkins Wellness does not recommend using the spa if the water temperature is above or below the spa’s control panel temperature range.

DISCLAIMERS
Watkins Wellness shall not be liable for loss of use of the CALDERA spa or other incidental or consequential costs, expenses, or damages, which may include but are not limited to, the removal of a permanent deck or other custom fixture. Any implied warranty shall have a duration equal to the duration of the applicable warranty stated above. Under no circumstances shall Watkins Wellness, or any of its representatives, be held liable for injury to any person, or damage to any property, however arising.
