Important Safety Instructions

Safety Instructions
All electrical work must be performed by a licensed electrician and conform to all national, state, and local codes. When installing and using this electrical equipment, basic safety precautions should always be followed, including the following:

DANGER
To reduce the risk of injury, do not remove the suction fittings of your spa or hot tub. Never operate a spa or hot tub if the suction fittings are broken or missing. Never replace a suction fitting with one rated less than the flow rate marked on the equipment assembly.

WARNING
When mixing acid with water, ALWAYS ADD ACID TO WATER. NEVER ADD WATER TO ACID.

WARNING
To reduce the risk of electric shock, fire or injury, service should only be attempted by a qualified Pool Service Professional.

WARNING
Do not operate electrolytic cell without proper flow or water circulation. A buildup of flammable gases would result in hazardous conditions.

WARNING

RISK OF ELECTRIC SHOCK, FIRE, PERSONAL INJURY, OR DEATH

• Installation must be done in accordance with the National Electrical Code® (NEC®, NFPA-70) and/or any other applicable local and national installation codes.
• A green-colored terminal (or a wire connector marked “G”, “GR”, “Ground” or “Grounding”) is provided within the terminal compartment. To reduce risk of electric shock, connect this terminal or connector to the grounding terminal of your electric service or supply panel with a conductor equivalent in size to the circuit conductors supplying this equipment.
• Power supply must be interconnected with pool pump motor power source. This insures the chlorinator and pool pump will turn on and off together.
• Use of chemicals other than those recommended may be hazardous. Follow the chemical manufacturers’ instructions.
• If the Flow/Temp/Salinity sensor is not installed in the electrolytic cell then it is recommended that it is installed in the same piping as the cell, up stream from the cell, and without any valves or diverters between them.
• The Flow/Temp/Salinity sensor must be mounted as shown in Figure 3.

TO REDUCE THE RISK OF INJURY

• The water in a spa should never exceed 104°F (40°C). Water temperatures between 100°F (38°C) and 104°F (40°C) are considered safe for a healthy adult. Lower water temperatures are recommended for young children and when spa use exceeds 10 minutes.
• Since excessive water temperatures have a high potential for causing fetal damage during the early months of pregnancy, pregnant or possibly pregnant women should limit spa water temperatures to 100°F (38°C).
• Before entering a spa or hot tub, the user should measure the water temperature with an accurate thermometer since the tolerance of water temperature-regulating devices varies.
• The use of alcohol, drugs, or medication before or during spa or hot tub use may lead to unconsciousness with the possibility of drowning.
• Obese persons and persons with a history of heart disease, low or high blood pressure, circulatory system problems, or diabetes should consult a physician before using a spa.
• Persons using medication should consult a physician before using a spa or hot tub since some medication may induce drowsiness while other medication may affect heart rate, blood pressure, and circulation.

WARNING
Prolonged immersion in hot water may induce hyperthermia. Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above the normal body temperature of 98.6°F (37°C). The symptoms of hyperthermia include dizziness, fainting, drowsiness, lethargy, and an increase in the internal temperature of the body. The effects of hyperthermia include: 1) unawareness of impending danger; 2) failure to perceive heat; 3) failure to recognize the need to exit spa; 4) physical inability to exit spa; 5) fetal damage in pregnant women; 6) unconsciousness resulting in a danger of drowning.

RISK OF ELECTRIC SHOCK
Install the power center at least five (5) feet (1.52 m) from the inside wall of the pool and/ or hot tub using non-metallic plumbing. Canadian installations
must be at least three (3) meters from the water.
Children should not use spas or hot tubs without adult supervision.
Do not use spas or hot tubs unless all suction guards are installed to prevent body and hair entrapment.
People using medications and/or having an adverse medical history should consult a physician before using a spa or hot tub.

WARNING

• People with infectious diseases should not use a spa or hot tub.
• To avoid injury, exercise care when entering or exiting the spa or hot tub.
• Do not use drugs or alcohol before or during the use of a spa or hot tub to avoid unconsciousness and possible drowning.
• Do not use a spa or hot tub immediately following strenuous exercise. Prolonged immersion in a spa or hot tub may be injurious to your health.
• Do not permit any electric appliance (such as a light, telephone, radio, or television) within 5 feet (1.52 m) of a spa or hot tub.
• The use of alcohol, drugs or medication can greatly increase the risk of fatal hyperthermia in hot tubs and spas.
• To avoid injury ensure that you use this control system to control only packaged pool/spa heaters which have built- in operating and high limit controls to limit water temperature for pool/spa applications. This device should not be relied upon as a safety limit control.
• A terminal bar marked “GROUND” is provided within the power center. To reduce the risk of electrical shock, connect this terminal bar to the grounding terminal of your electric service or supply panel with a continuous copper conductor having green insulation and one that is equivalent in size to the circuit conductors supplying this equipment, but no smaller than no. 12 AWG (3.3 mm). In addition, a second wire connector should be bonded with a no. 8 AWG (4.115mm) copper wire to any metal ladders, water pipes, or other metal within five (5) feet (1.52 m) of the pool, spa, or hot tub.

ATTENTION
INSTALLER: Install to provide drainage of compartment for electrical components.

CAUTION
It is important to note that certain materials used in and around swimming pools and spas may not be compatible with chemicals commonly used to purify pool and spa water (e.g. acids, chlorine, salt, stabilizers, etc.).
As such, Zodiac Pool Systems LLC does not warrant or guarantee that the chlorinated water generated by the salt water chlorinator will not damage or destroy certain types of plants, decking, coping and other materials in and around your pool and/or spa. Before selecting materials to be used in and around your pool and/or spa, please discuss all options with your contractor to assess the compatibility of such materials and chemicals.

Some helpful considerations may include:

• Choosing plants that can withstand splash out of pool water containing chlorine and/or salt and other water purification chemicals.
• All metal components used in and around a pool should be of a high grade, quality stainless steel.
• Careful selection of masonry products. The porosity and hardness of natural stones varies greatly. Therefore we recommend you consult with your builder or stone contractor on the best choice for stone materials around your pool or spa.
• Sealing all masonry products. Professionals in the stone industry specify that even natural stone, especially when used outdoors, be sealed to prevent weathering, staining, and premature degradation. Consult with your stone or deck contractor for the proper sealer for the masonry products you have selected to use around your pool or spa.
• For the optimal results, sealers should be reapplied on a regular basis. Reapply the protective sealer on a schedule per the manufacturer’s instructions.

Product Description
The salt chlorinator system use a process known as electrolysis to produce sodium hypochlorite (liquid chlorine) from a low concentration of salt added to the pool water. Hypochlorite kills bacteria, oxidizes organic material, and kills algae then reverts back to salt. The system then reuses the salt and the process starts over again.

Installation Instructions

WARNING
When using electrical products, basic precautions should always be followed, including the following:

• RISK OF ELECTRIC SHOCK WHICH CAN RESULT IN SERIOUS INJURY OR DEATH. Before attempting installation or service, ensure that all power to the device is disconnected/turned off at the circuit breaker.
• Grounding is required. The unit should be installed by a qualified service representative and should be properly grounded.
• Install to permit access for servicing.
• Read the Important Safety Instructions section. Before attempting any electrical wiring, be sure to read and follow Safety Instructions. Wiring should only be attempted by a qualified professional.

Installation of Power Supply
Always install the power supply of the salt electrolysis systems VERTICALLY on a solid and rigid surface (wall) as shown in the recommended installation diagrams. In order to guarantee a good state of conservation, the power supply should be installed in a well-ventilated dry place. Due to IP degree of the power supply, the salt electrolysis systems should not be installed outdoors. The power supply should be installed a bit distant from the electrolysis cell so that it cannot accidentally suffer water splashes.

Beware of corrosive atmosphere formation due to pH decreasing solutions (specially, those ones based on hydrochloric acid “HCl”). Do not install the salt electrolysis systems near to any stores of these chemicals. We strongly recommend the use of chemicals based on sodium bisulphate or diluted sulphuric acid.

Power supply must be connected to the electrical control box of the pool, so that the pump and the salt electrolysis systems are turned on (and off) simultaneously.

IMPORTANT
Circuit breaker curve specification should be “D” or “K”.

Installation of the Electrolysis Cell
The electrolysis cell is made of polypropylene in whose interior the electrodes are placed.
The electrolysis cell must be always installed indoors and after the pool filter, and after any other equipment that may be present (heat pumps, control systems, etc.).

The installation of the cell should allow easy access to the installed electrodes by the user.
The electrolysis cell should be installed VERTICALLY in a place of the pipe that can be easily isolated from the rest of the installation by two valves, so that the tasks of maintenance can be carried out with no need of partial or total draining of the swimming pool.

Where the cell is installed on a by-pass (recommended option), a valve to regulate the flow must be introduced.

1. Flow direction marked in the cell must be respected. Recirculation system must guarantee the minimum flow stated in the Technical Specifications Table.
2. The system flow detector activates if there is no recirculation (flow) of water through the cell or if flow is very low, whenever the cell entry valves are open.

WARNING
A pressure switch or mechanical flow detector palette is additionally supplied with the unit which provides a redundant security in absence of water flow through the cell.
The flow detector must be revised periodically as it is a mechanical element.

Installing Control/Power Centers

NOTE: The control/power center should be located at or near the equipment pad.

CAUTION
The control/power center is not to be considered as suitable for use as service equipment. Therefore, it is required to have the appropriate means of disconnection, circuit isolation, and/or branch circuit protection installed upstream of the power center.
Locate the control/power center at least five (5) feet or more away from pool/spa and five (5) feet off the ground. All national, state, and local codes are applicable.

NOTE: For Canadian installations, the control/power center must be at least three (3) meters (9.8 feet) away from the pool/spa and 1.5 meters (5 feet) above the ground.

Pool Water Preparation

ATTENTION

INSTALLER: Various application notes (including more detailed instructions) are available from the Dealer covering installation, operation, maintenance, and plumbing of the chlorinator system.

Determining Pool Size
(Liters of Water in Your Pool)

• Rectangular Pools
  Average length (meters) x average width (meters) x average depth (meters) = m3 capacity m3 capacity x 1000 = liters.

• Circular Pools
  Diameter (meters) x diameter (meters) x average depth (meters) x 0.79 = m3 capacity m3 capacity x 1000 = liters

• Oval Pools
  Long diameter (meters) x short diameter (meters) x average depth (meters) x 0.79 = m3 capacity m3 capacity x 1000 = liters

• Sloping Sides
  Multiply total m3 by 0.85 = m3 capacity m3 capacity x 1000 = liters

Determining Pool Size
(Gallons of Water in Your Pool)

• Rectangular Pools
  Average length (feet) x average width (feet) x average depth (feet) x 7.5 = gallon capacity

• Circular Pools
  Diameter (feet) x diameter (feet) x average depth (feet) x 5.9 = gallon capacity

• Oval Pools
  Long diameter (feet) x short diameter (feet) x average depth (feet) x 5.9 = gallon capacity

• Sloping Sides
  Multiply total gallons by 0.85 = gallon capacity

Selecting Model Size
When sizing a chlorinator system for a pool or spa, one should consider the typical and worst-case loads on the pool/spa disinfection system. One should account for relevant variables which impact disinfectant demand and consumption. Following are some common variables which affects demand for disinfectant (such as chlorine or bromine):

• Local code requirements should be consulted to know the target level (typically in ppm such as 1 ppm free chlorine) and ensure compliance with the minimum level of residual disinfectant in the water.

• Bather load. The sanitizer demand increases as the number of bathers increase.

• Exposure to vegetation and airborne debris.
  Dense landscaping increases nitrates which introduce nitrogen. These nitrogen compoundsreact with chlorine and consume it, thereby reducing chlorine available for disinfection and maintenance of sanitation.

• Aeration, splashing, straying of water, and features such as waterfalls. These things increase the demand for sanitizer by creating very high and air mixing.

• Surface area. A larger surface area enables more disinfectant consumption. Use of a pool or spa covers help to minimize air/water mixing and introduction of debris.

• Volume. Greater volume dilutes the disinfectants.

• Average water temperature. The demand for sanitizer changes as the temperature increases or decreases.

• Amount of direct sunlight/UV exposure.
  Sunlight exposure increases the rate at which sanitizer is consumed; indoor pools may be unaffected by this factor.

• Level of cyanuric acid (CYA) in water.
  CYA slows down the destruction of chlorine by the sun’s ultraviolet rays, but excessive CYA levels negatively affect the oxidation ability of chlorine.

• Chemical dilution due to rainfall, backwashing, etc. The loss of water containing sanitizer also creates loss of sanitizer.

• Pump and filter runtime. Sanitizer is only introduced when the pump is running and water is being circulated, otherwise no disinfectant is being circulated into the body of water.

• Circulation patterns and speeds within the pool, spa, or wave pool. If the pump speed is reduced (or turned off) to save electrical energy the is a decreased or elimination of filtration and introduction of disinfectant into the water. When the pump speed is increased or turned on, chlorine demand may be increased.
  If the disinfectant level falls below that which is required by the local jurisdiction having authority, the operator may need to manually add disinfectant and other adjustment chemicals to quickly adjustment chemicals to quickly adjust the water chemistry levels to meet the requirement.
  General guidelines for Pool Size
  Chlorine generators should be capable of supplying no less than 3 lbs. (1.4 kg) of chlorine per day, per 10,000 gallons (37,8 KL).
  General guidelines for Spa Size
  Chlorine generators should be capable of supplying no less than 3 lbs. (1.4 kg) of chlorine per day, per 1,000 gallons (3.8 KL).
  ** These guidelines are provided as general guidelines only. Every pool and spa system is unique, and all considerations described in the New Installation section must be considered when sizing a chlorinator for your pool or spa system.

Chemistry You Need to Know

• Chlorine Stabilizer (cyanuric acid) may be needed to maintain proper levels of chlorine.
  Most unstable chlorine is destroyed by the UV radiation from the sun within 2 hours. When used, cyanuric acid levels shall not exceed 100 ppm. Follow all local, State, and Federal code requirements for minimum and maximum chlorine residual levels when using cyanuric acid.

• Metals (some metals) can cause loss of chlorine. Also, metals can stain your pool.
  Have your local pool professional check for metals and recommend methods of removal.

• Chloramines should not be present in pool water. When organic materials combine with free chlorine, chloramines are formed. This ties up the free chlorine in your pool and does not allow the chlorine in your pool to disinfect.
  Chloramines also cloud pool water and burn the eyes. [Shock to remove chloramines at the initial startup of the pool.

• Shocking (Superoxidation) is also a means of burning out the organic material that has combined with chlorine. This method involves the manual addition of chemicals to quickly raise the level of chlorine. When the chlorine level is quickly raised to 5 – 15 ppm the pool water is said to have been shocked.
  NOTE: On initial startup of a pool, it is best to shock from an outside source, i.e., use a shock treatment available at your local pool supplier.
  CAUTION
  Never use dry acid to adjust pH in arid geographic areas with excessive evaporation and minimal dilution of pool water with fresh water. A buildup of by-products can damage the electrolytic cell.

• Total Dissolved Solids (TDS) adding salt to pool water will raise the TDS level. While this does not adversely affect the pool water chemistry or clarity, the pool water professional testing for TDS must be made aware salt has been added for the sanitizing system. The individual performing the TDS test will then subtract the salinity level to arrive at the correct TDS level.

• New pool water in a recently filled or newly refinished pool may contain undesirable matter. This undesirable matter could interfere with the salt water chlorinator’s ability to sanitize properly. Make sure the water is tested by a pool professional and properly balanced before turning on the chlorinator system.

• Sequestering Agents in some areas the total hardness of your source water may be unusually high. High total hardness can contribute to scale formation in the pool.
  Sequestering agents will help keep minerals in solution and under some conditions can prevent this from happening. Consult your pool professional about the use of a sequestering agent.

Optimum Pool Water Conditions
In accordance with Association of Pool and Spa
Professionals® (APSP®) standards, we recommend the following water balance conditions be maintained on an on-going basis to protect the pool finish and equipment and ensure the pleasing appearance of the water. This Salt Water Chlorinator is warranted to operate properly only if these conditions are met.

Free Chlorine| 1.0 – 3.0 ppm. Continuous exposure to levels above

3.0 ppm may cause corrosion of pool metals.

---|---
Combined Chlorine (Chloramines)| None (Super Chlorinate to remove all chloramines).
pH| 7.4 – 7.6 (USE MURIATIC ACID to lower pH and Soda Ash to raise pH).
Chlorine Stabilizer (Cyanuric Acid)| 50 – 75 ppm
Total Alkalinity| 80 – 120 ppm
Calcium Hardness| 175 – 400 ppm
Metals (Copper, Iron, Manganese)| None
Nitrates| None

Chlorine Testing

Use a home test kit or ask your pool professional to test your water. It is recommended that chlorine test samples be taken from two (2) places, described below. Compare the two (2) samples. A higher level should be found at the pool return line. The higher level at the pool return line indicates the salt water chlorinator system is producing chlorine.

Take test samples:

1. At the pool return line.
2. Eighteen (18) inches (457 mm) below the surface and well away from the pool return line.

CAUTION
It is important to note that certain materials used in and around swimming pools and spas may not be compatible with chemicals commonly used to purify pool and spa water (e.g. acids, chlorine, salt, stabilizers, etc.).
As such, Zodiac Pool Systems LLC does not warrant or guarantee that the chlorinated water generated by the salt water chlorinator will not damage or destroy certain types of plants, decking, coping and other materials in and around your pool and/or spa. Before selecting materials to be used in and around your pool and/or spa, please discuss all options with your contractor to assess the compatibility of such materials and chemicals.

Some helpful considerations may include:

• Choosing plants that can withstand splash out of pool water containing chlorine and/or salt and other water purification chemicals.

• All metal components used in and around a pool should be of a high grade, quality stainless steel.

• Careful selection of masonry products. The porosity and hardness of natural stones varies greatly. Therefore, we recommend you consult with your builder or stone contractor on the best choice for stone materials around your pool or spa.

• Sealing all masonry products. Professionals in the stone industry specify that even natural stone, especially when used outdoors, be sealed to prevent weathering, staining, and premature degradation.
  Consult with your stone or deck contractor for the proper sealer for the masonry products you have selected to use around your pool or spa.

• For the optimal results, sealers should be reapplied on a regular basis. Reapply the protective sealer on a schedule per the manufacturer’s instructions.

Salt (NaCl Sodium Chloride)

When to Add Salt
For a new concrete pool or newly resurfaced pool it is recommended to wait 30 days (surface should be completely cured) before adding salt. Follow the pool surface manufacturer’s guidelines for your particular pool. For vinyl and fiberglass pools, salt can be added at start up. After start up add salt as necessary to maintain proper level

What Type of Salt to Use

• The purer the salt the better the life and performance of the electrolytic cell. Use a salt that is at least 44% pure NaCl. The salt is an evaporated, granulated, non-iodized salt. Consult your salt supplier.

• Avoid using salt with anti-caking agents (sodium ferrocyanide, also known as YPS or yellow prussiate of soda) that could cause some discoloration of fittings and surface finishes in pool.

• Water conditioning salt pellets are compressed forms of evaporated salt and may be used but will take longer to dissolve.

• Do not use calcium chloride as a source of salt.
  (Use sodium chloride only).

• Do not use rock salt (insoluble impurities mixed with the rock salt can shorten the life of the unit).

How Much Salt to Use
Use Table 2 to determine how much salt will be needed. Most pools contain some salt depending on the water source and chemicals used for sanitizing.
If the salt water chlorinator has not been wired and turned on yet, a salt test strip or a hand held meter calibrated for NaCl (salt) can be used to determine the existing salt concentration of the water. If the unit is wired (connected), use it to determine the salinity.
Water temperature can affect the salinity readout, always test salinity at the equipment locations.

• 3.0 to 3.5 gpl of salt is recommended for optimum water conditions.
• Low salt concentration below 2.0 gpl will cause premature cell failure.
• High salt concentration above 6.0 gpl may cause corrosion damage to pool fixtures.
  NOTE: Should too much salt be inadvertently added to the pool see the Troubleshooting section.
  NOTE: To convert gpl (grams per liter) of a salt solution to ppm (parts per million) of a salt solution multiply by 1000, i.e., 3.0 gpl salt X 1000 = 3000 ppm salt.

How to Add Salt to the Pool

1. Turn on pump to circulate pool water.
2. IMPORTANT – Turn the chlorine production off by pressing the arrow button A and setting CHLORINE PRODUCTION Rate to 00%.
3. Determine the salt concentration using a portable test meter (test ship, conductivity meter).
4. Broadcast or spread the salt into the outer perimeter of the pool, or into the shallow end of the pool for quick and even distribution.
5. To avoid clogging the filter or damaging power center and pump, do not add salt through either the skimmer, main drain, or surge tank.
6. Brush the pool bottom and allow water to circulate for 24 hours to dissolve completely and mix evenly with the pool water.
7. After 24 hours, verify correct salt reading with the test meter.
8. Turn on the system and set to desired chlorine production rate (pressing the arrow buttons A or B).
   NOTE: For a new concrete pool or newly resurfaced pool it is recommended to wait 30 days (surface should be completely cured) before adding salt. Follow the pool surface manufacturers guidelines for your particular pool. For vinyl and fiberglass pools, salt can be added at start up.

  The power supply includes a safety system that acts in the absence of flow in the cell, the power supply will stop production in the event of insufficient flow and will reset when the flow is restored.

Operation

CAUTION
Before attempting to operate, refer to the Pool Water Preparation part of the New Installation section. Also, do not adjust chlorine production above 00% until it is certain that salt has been dissolved in pool.
Operating without salt will damage the electrolytic cell.
NOTE: The chlorinating system only operates when the pump is running. During hot weather months you may need to increase pump run time to allow sufficient chlorine production.
Try initially setting the pool pump run-time to 12 hours per day. It will take a few days to get just the right pool pump operating time.

The key points are:

• Check chlorine level on a regular basis and adjust the chlorine production rate (%) accordingly.
• Operate pool pump at least the minimum time needed for good filtration.
• The pool pump timer reduces energy consumption.

NOTE: Exception – for cold weather operation:
If the salt water chlorinator is set to run 24 hours a day through the winter, extremely cold water temperatures can contribute to a reduction in the operating life of the electrolytic cell. Sometimes it will be necessary to run the chlorinator at a very low production rate (10-20%) or to turn the unit off.

Start-Up

Shocking
Shock (superoxidation) the pool water from an outside source at the time of pool startup to burn off contaminates. During normal operating conditions the chlorinator is capable of generating a sufficient level of chlorine for sanitation within several hours. However, if the pool water has a high chlorine demand due to startup conditions then the chlorinator will not be able to produce enough chlorine to reach break-point chlorination. Shocking involves the manual addition of chemicals to quickly raise the level of chlorine. When the chlorine level is quickly raised to 5 – 15 ppm the pool water is said to have been shocked Wait until the chlorine level has returned to 1 – 3 ppm before turning on the salt water chlorinating system.

Apply Power

1. Check that the filter is 100% clean, and ensure that the swimming pool and the installation do not contain copper, iron or algae. Ensure that any heating equipment on the pool is suitable for use in salt water.

2. Ensure that the swimming pool water is balanced, because like that the chlorine produced is used more efficiently and effectively, and ensures that the life of the electrodes is prolonged, as well lower scale build-up in the pool. Water should be maintained within the parameters shown below.

3. pH must be in the range 7.2-7.6

4. total alkalinity must be in the range 0.059-0.12 ppm

5. Although the electrolysis system can operate within a salinity range of 4–6 g/l, the minimum recommended level of salt, 5-6 g/l, should be maintained adding 5-6 kg per m3 of water if the water did not previously contain salt. In the case of LS models, the range of recommended salinity is 2 g/l. Always use common salt (sodium chloride), without additives like iodides,that is “apt for human consumption”. Never add the salt through the electrolysis cell. Add it directly to the swimming pool or into the balance tank.

6. When adding the salt, and in case the swimming pool is going to be used immediately, carry out a treatment with chlorine. An initial dose of 2 g/m3 of trichloroisocyanuric acid may be added.

7. Prior to starting up the salt chlorinator,disconnect the power supply to the salt chlorinator and run the pump for 24 hours to ensure that the salt is completely dissolved.

8. Next, reconnect the power supply and turn on the salt chlorinator, locating the production level so that free chlorine concentration stays within the recommended range (0.5 – 1.5 ppm).
   NOTE: In order to establish the free chlorine level you will need to use a test kit.

9. In outdoor swimming pools it is advisable to maintain a level of 50-75 ppm of chlorine stabilizer (cyanuric acid) in the water. This will help to stop the chlorine that is in the water from being destroyed by the sun.

Recommendations

DO List

• Read and keep your manual in a safe place.
• Increase chlorine production rate before a large number of bathers enter the pool and return to normal afterwards.
• Increase chlorine production rate when temperature goes up.
• Increase chlorine production rate when the number of bathers goes up.
• Use stabilizer (cyanuric acid) to stabilize chlorine in pool.
• Mount power center in shade or out of the direct sunlight whenever possible.
• Decrease production rate when temperature goes down (for example, in the Fall and Winter seasons).
• Take pool water sample to pool professional once per month.

DON’T List

• Do not get fertilizer in your pool. Fertilizers contain nitrates which cause a high chlorine demand on pool water.
• Never use dry acid to adjust pH in arid geographic areas with excessive evaporation and minimal dilution of pool water with fresh water. A build up of by products can damage the electrolytic cell.
• Do not add chemicals or salt to the pool unless the chlorinator is turned off.
• Do not let chlorine stabilizer (cyanuric acid) drop below 50 ppm.
• Do not add salt without first checking the pool salinity level. Too much salt can disable and possibly damage the chlorinator.

User Maintenance

Instructions
The following information describes how to care for your sanitizing system.

IMPORTANT
Always test the chlorine levels of your pool before each use.

Daily

• Chlorine Test. Test pool water chlorine level with a reliable test kit. Maintain ideal range by adjusting the chlorine production rate.
  Recommended free chlorine is 1 – 3 ppm.
  NOTE: It is recommended that chlorine test samples be taken from two (2) places, one at the pool return line, the other well away from the pool return line. Compare the samples. A higher level should be found at the pool return line. The higher level at the pool return line indicates the system is producing chlorine.

• pH Level Test. Test the pH level of your pool with a test kit. If necessary, adjust to maintain a pH level of 7.4 – 7.6.

CAUTION
Never use dry acid to adjust pH in arid geographic areas with excessive evaporation and minimal dilution of pool water with fresh water. A build up of by products can damage the electrolytic cell.

• Total Alkalinity Test. Test pool water for total alkalinity with a test kit. Take steps necessary to maintain an alkalinity of 80 – 120 ppm.

Monthly

• Salt Level Test. Test pool water salt level with a portable test meter (conductivity meter).
  Maintain the ideal range of 3.0 – 3.5 gpl for optimum performance. If additional salt is required, follow the procedures and charts described in the New Installation section. If salt level does not rise after 24 hours, see the
  Troubleshooting section.

• Pool Water Sample. Take water sample to local pool store for testing.

• Stabilizer (Cyanuric Acid). Test pool water  stabilizer (cyanuric acid) level using a test kit or by having a water sample tested by a pool professional. Maintain ideal range of 50 – 75 ppm. Follow your pool professional’s recommendations.

• Metals Test. It is recommended that the pool water be tested periodically for the presence of metals such as copper, iron, and manganese.
  These metals should not be present in the pool water. If those metals are present, contact your local pool professional.

• Electrolytic Cell Cleaning – As Needed

• Automatic Cleaning. The chlorinator control system has an automatic cleaning feature (cell reversing) that removes scale deposits from the electrolytic cell.
  NOTE: Automatic Cleaning does not interrupt Chlorine Production.
  “Scale” is a white crusty deposit that forms in excessively hard water or from pool water that is out of balance and in a scaling condition. Following the installation of the salt water chlorinator system, check the cell once a month for several months. If the cell is clean, replace and re-check at the end of each swimming season. If the cell shows excessive scaling, go on to Acid Wash Cleaning.

WARNING
Always turn pump off prior to installing or removing any components from the pool’s plumbing. Your pump/filter system is operated under pressure and pressure must be released before you begin to avoid system damage or personal injury. Open the air relief valve on your pool filter to release the pressure in the system.

• Acid Wash Cleaning. If the electrolytic cell has a tendency to scale, it is recommended that every two (2) months the cell be removed and inspected for scale formation and/or debris.
  Some filters allow debris to pass through to the cell which could lodge between the plates in the cell. A small amount of scale formation is normal. If by looking through the cell it is observed that there is excessive scale formation between the plates or debris is present, the cell must be cleaned as follows:

1. Use a high pressure jet of water from a garden hose. If the cell cannot be reasonably cleaned in this manner, acid cleaning is necessary.

2. Remove the cell from the plumbing. If necessary, replace the cell with the spool piece (sold separately). Remove the sensor from the port.
   WARNING
   Inhalation of muriatic acid vapor or contact with skin or eyes can cause serious injury or death. Wear goggles and rubber gloves, and perform cleaning in a well-ventilated area. Add acid to the water, do not add water to the acid as splashing could result.

3. Pour the acid/water mixture inside the cell. A foaming action will begin, which is caused by scale (calcium carbonate) being dissolved from the plates. If rigorous foaming action does not begin, the cell does not need to be cleaned (STOP THE CLEANING PROCESS – go on to step “5”). Otherwise, allow the cell to remain in the solution until the foaming has stopped.
   However, do not leave in acid for more than 1/2 hour.
   IMPORTANT
   Excessive acid washing will damage electrolytic cell.

4. Rinse the cell thoroughly with clean tap water and inspect. If deposits are still visible, repeat the cleaning procedure. Additional acid may need to be added to the solution.

5. Rinse the cell again with clean tap water and inspect. If clean, replace the cell and resume normal operation.

6. If the acid wash procedure is necessary, it is recommended that a sample of pool water be analyzed by an authorized Zodiac service representative for excessive hardness and/or improper water balance.

7. If no scale or debris deposits are observed in the cell after two (2) bimonthly inspections, it is not necessary to continue bimonthly inspections.
   However, due to possible changes in pool water chemistry and filtering effectiveness, it is recommended that the cell be removed for inspection at least twice a year.

Winterizing
Very little chlorine is needed in cold water. Below 51°F (11°C), operating the chlorinator in cold water might result in over-chlorinated pool water.
If preventative measures are not taken, freezing water may cause severe damage to the cell and flow/ temp/salinity sensor. Prevent freeze damage to the cell and flow/temp/salinity sensor by running pump continuously or winterize pool by draining water from pump, filter, and all intake and return lines. Remove the cell, clean and store it.

When a FREEZE CONTROLLER is used on pump equipment and the chlorinator is run through the winter, turn the CHLORINE PRODUCTION down to 10 – 20%. Otherwise, chlorine production will exceed the recommended level of 1 – 3 ppm.

NOTE: A chlorine level above 3 ppm may cause corrosion of pool metals and possibly cause damage to associated pool equipment.

Troubleshooting

NOTE: Turn off power to unit prior to attempting service or repair.

The production indicator always shows “0” at any selected production level

| –     Check the electrodes

–     Check the output connections between power supply and the electrolysis cell

–     Check the salt concentration

The power supply doesn’t switch on

| –     Check the input connections are properly connected to the mains

–     Check the fuse status located at the bottom of the device

The chlorine level into the water is very low

| –     Check the chlorine measurement on the nozzles

–     Check the chemical parameters into the water (pH, combined chlorine, isocyanuric acid) are correct

–     Increase filtration time

–     Add chlorine stabilizer (isocyanuric acid) until reach 50-75 ppm
