IMPORTANT SAFETY INSTRUCTIONS

WARNING – WHEN USING ELECTRICAL PRODUCTS, BASIC PRECAUTIONS SHOULD BE FOLLOWED, INCLUDING THE FOLLOWING:
This manual contains information and instructions for proper operation and maintenance of your MTI bath. Failure to follow these instructions could result in personal injury, electrical shock or fire. INSTRUCTIONS PERTAINING TO RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS.

READ AND FOLLOW ALL INSTRUCTIONS

Do not permit children to use this unit unless they are closely supervised by an adult at all
Use this unit only for its intended use as described in this manual. Do not use attachments
Do not operate this unit without guard over the suction fitting.
The water in a whirlpool should never exceed 40˚ C (104˚ F). Water temperatures between 38˚ C (100˚ F) and 40˚ C (104˚ F) are considered safe for a healthy adult. Use time should be limited to approximately 10 minutes, followed by a shower to cool down. Longer exposures may result in hyperthermia, which can be fatal. The symptoms of this condition are nausea, dizziness and fainting. Lower water temperatures are recommended for extended use (exceeding 10 – 15 minutes) and for young children.
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 bath water temperatures to 38˚ C (100˚ F).
The use of drugs or alcoholic beverages before or during hydrotherapy bath use may lead to unconsciousness with the possibility of drowning. Never use the hydrotherapy bath while under the influence of alcohol, anticoagulants, stimulants, antihistamines, vasoconstrictors, vasodilators, hypnotics, narcotics or tranquilizers.
Persons with a medical history of heart disease, low or high blood pressure, circulatory system problems, or diabetes should consult a physician before using a hydrotherapy bath.
Persons using medication should consult a physician before using a hydrotherapy bath since medication may induce drowsiness, affect heart rate, blood pressure and circulation.
DANGER: To reduce the risk of injury, enter and exit the bath slowly.
WARNING: Never operate electrically connected devices in or within 5′ of the bath. Never drop or insert any object into any opening within the hydrotherapy bath.
DANGER: Risk of electric shock. Connect only to circuits protected by a Ground Fault Circuit Interrupter (GFCI). Such a device should be installed by a licensed electrician and should be tested on a regular basis (at least monthly). To test the GFCI push the TEST button. The GFCl should interrupt the power. Push the RESET button and the power should be restored. lf the GFCI fails to operate in this manner there is the possibility of an electric shock. DO NOT USE. Disconnect the unit and have the problem corrected by a qualified service technician. To avoid the possibility of personal injury and discoloration of the acrylic surface, the inlet water temperature should not exceed 60˚ C (140˚ F).
DANGER: Disconnect power before servicing.
A pressure wire connector is provided on the exterior of the pump or control within this unit to permit connection of a bonding conductor between this unit and all other exposed metal in the vicinity, as needed to comply with local requirements.

ATTENTION INSTALLER!
Access must be provided to each pump and/ or electrical component on your tub. The access panel must have a minimum size of 16” x 14” for installation and future servicing of the equipment. MTI Baths, Inc. will not authorize any service unless clear access is available. Access from a crawlspace or incomplete access to all equipment may result in warranty claims being denied.

INSTALLATION INSTRUCTIONS

Read all instructions before installing tub.

BEFORE INSTALLING:
Inspect tub thoroughly.

Damage from shipping or delivery must be reported to carrier immediately. Do not install damaged tub. MTI is not responsible for damage occurring in transit.
Factory defect must be reported to factory before tub is installed. Defects or damage claimed after installation will be excluded from warranty.
Important – Measure tub on site carefully before framing or cutting any deck materials. Specifications are subject to change without notice. MTI Baths is NOT responsible for any preparatory labor or materials.

CAUTION: DO NOT LIFT TUB BY PIPING OR PUMP DO NOT RUN PUMP DRY T o Do So May Cause Damage Not Covered By the Warranty

ATTENTION INSTALLER!
This tub must be tested for leaks and proper operation prior to enclosure of surrounding areas. Failure to do so will void the warranty. This tub was water tested at the factory and found to be leak free and fully operational prior to shipping. Freight handling and job site exposure may have deteriorated the condition of the product. It is the responsibility of the installer to thoroughly test the unit prior to installation. Tubs are warrantied for indoor use only. Alcove soaker and whirlpool tub models with integrated skirt and tile flange do not come standard with factory installed pre-leveled foam base and will ship with support blocks adhered to the bottom of the tub to protect the integrated skirt during shipment, handling, and storage of the product. Blocks must be removed prior to installation, and the tub leveled at the rim and supported by a proper bedding compound upon installation. See detailed installation instructions for more information.

Place the tub on a flat surface such as the driveway.
Seal the drain with tape.
Fill tub to overflow and allow tub to stand for five minutes without the pump running. Examine all fittings carefully for leaks. NOTE: The overflow is a plumbing device designed to prevent water from reaching a certain level in your tub. DO NOT, under any circumstances, tape off or block the overflow in any way. Any controls located above the normal water line are designed to be water-resistant, not water-proof. The controls will not leak under normal usage, however, they are not warranted against leaks when improperly used or subjected to conditions for which they were not designed.
Plug the pump, blower and/or in-line heater into a 110v GFCI outlet. Start the pump, blower and/or in-line heater, and check all fittings for leaks. Hand tighten if necessary.
Check that all optional equipment is functioning properly and that the features on the tub match exactly what was ordered.
If any leaks or operating problems are discovered, do not complete installation until prob-lems are resolved. MTI will not be responsible for any costs involved with removing or reinstalling the tub, or for the costs of any surrounding materials.

See troubleshooting section of this manual or call for assistance: 800-783-8827 Always protect tub from construction damage by using a protective cover. Damage, including chips and scratches, incurred at the jobsite is excluded from warranty. Do not store tub in tem-peratures below 32 degrees Fahrenheit. Proper waste and overflow installation is the responsibility of the installer. MTI does not warrant leaks associated with improper waste and overflow installation.

WARNING: Certain cleaning products will permanently damage the acrylic surface. Read product label carefully before applying any cleaning product. Never use anything abrasive, aerosol sprays or any product that is described as “scrubbing bubbles”. Never leave a full or filling bath unattended.

There are many possible ways to install your new MTI tub, and some may require different framing than the following instructions. Keep in mind that the framing should always provide a level surface for the rim of the tub and sufficient space below the tub for bedding compound. Access must be pro-vided to each pump and/or electrical component on your tub. The access panels must have a minimum size of 16” x 14” for installation and future servicing of the pump and/or electrical equipment. MTI will not authorize any service unless clear access is available. Access from a crawlspace or incomplete access to all equipment may result in warranty claims being denied. Additional access to plumbing fixtures is strongly recommended. It is the responsibility of the installer to comply with local plumbing codes regarding pump and plumbing access. Note: Do not allow any mate-rial such as insulation within 8” of pump. Pump must have sufficient air space surrounding it for circula-tion and proper operation.

GENERAL INSTALLATION GUIDELINES

Take all final installation dimensions from your tub. All printed specifications for MTI tubs have +/- ½” tolerance AND ARE SUBJECT TO CHANGE AT ANY TIME. Note: add approximately 2-3 inches to the over-all tub height for drop-in tubs equipped with pre-leveled foam base and/or pre-leveled frame. The bolts/screws through the mounting feet on the pump may be loosened or removed once the tub is in place, if necessary for future servicing. MTI tubs are not equipped with leveling feet! Wooden blocks under must be removed prior to installation. The tub must be leveled from the top flange in both directions.MTI recommends Quikrete #1103 sand/topping mix for bedding the tub. Plaster, sheet rock mud and sand are NOT sufficient bedding compounds! Determine the final height of the tub rim by measuring from the underside of the rim to the floor on the drain side and add ½” to allow for bedding compound, unless your tub has our factory installed pre-leveled foam base. The tub must be leveled by the rim, and supported by the bedding (or MTI foam base) under the full length of the tub bottom. It is recommended to use a plastic sheet barrier on top of and underneath the bedding compound. Carefully lower tub into place. Shift tub side to side to settle into compound. The tub will not drain properly if not level both front to back and side to side. Use care not to damage any plumbing, wiring or other options when bedding the tub. Let compound harden over-night before use. Failure to properly bed the tub will void any warranty on the tub shell.

NOTE: Pre-leveled frame eliminates the need to frame the walls or use bedding compound to level the tub, assuming the floor is perfectly level. If not, some bedding compound may be needed to achieve level. The pre-leveled frame adds ½ to 3 inches of height, depending on the specific model of tub.

ALCOVE

Mark a level line on the stud walls using the measurement determined above. A 2” x 2” or similar stringer will be attached to the studs touch-ing this line. All mounting surfaces must be level to allow for proper drainage. Framing of the same height should be constructed across the front of the tub for skirt, tile or other material. Remember to allow for access to each pump, blower and/or electrical component.

DROP IN
Use the above dimension as the finished deck height from the floor. The drop in opening should be approximately 1 ½ inches smaller than the outside dimensions of the tub. This will create a ¾ inch ledge to support the entire rim of the tub. It is best to have as large an opening as possible in the deck to clear the plumbing and other tub accessories during install while still pro-viding full support for the rim. Full size templates for oval tubs can be purchased through your distributor.

NOTE: Most MTI BASICS tubs are NOT undermountable. See individual tub specification sheets.

Have tub at jobsite and measure or template very carefully before cutting any decking materials. MTI is not responsible for any preparatory labor or materials. If your application calls for solid surface material covering only the width of the tub flange, additional support for the solid surface material is not necessary.

PRE-LEVELED FRAME
Place tub into proper location and attach to floor with 2” screws drilled through frame. This system does not require bedding compound unless subfloor is not level. A self leveling compound can be used to level the subfloor. Read and follow all manufacturers directions.The pre-leveled frame adds approximately 2”-3” to the height of the bath.

WOOD SKIRT
Prime and paint front and back of skirt to seal wood before attempting installation. Secure to floor cleat and wall supports using 4d finish nails.

TILE FLANGE – FACTORY INSTALLED

Mark flange of tub where it aligns with wall studs
Drill a minimum of three holes on each side of the tub flange to align with selected wall studs. Place enough bedding compound (MTI recommends Quickrete Sand Mix) to fill void between the bottom of the tub and floor. If your tub was ordered with the pre-leveled foam option, no bedding compound is necessary. Note: If your floor is not completely level, use enough bedding compound to achieve level.
Work tub into bedding compound.
Ensure that tub is level, both front to back and side to side.
Attach tub to wall studs using the pre-drilled holes in the flange.
Fill the void between the tile flange and tub with clear silicone.

TILE FLANGE KIT – FIELD INSTALLATION.

Clean tub flange.
Apply supplied adhesive to tub flange and tile flange with brush, being careful not to get adhesive on top of tub.
Position tub 2-3” from wall.
Apply tile flange to tub flange.
Position the tub against the walls. Adhesive will set in five minutes.
Seal / fill the void between the tile flange and tub with clear silicone.
Trim any excess flange.

INSTALLATION INSTRUCTIONS FOR AIR BATHS

Never handle the bath by the blower, piping or other equipment.
Make sure the manifold and airlines are protected when moving the tub into the house.
An access panel of at least 16” x 14” must be provided for the blower for any future servicing.
The blower must not be insulated and must have sufficient air space to permit proper operation. Surrounding ambient air temperature should be between 72º F and 86º F.
The heating element on your blower heats the air blown into the tub to prevent the water from cooling too quickly. It will not, under any circumstances, reheat or maintain the temperature of the bath water.
The area underneath and around the tub must be cleaned thoroughly before finalizing installation to prevent any particles from entering the blower or being blown into the air jets.
Before filling the tub, clean installation debris and dirt from the interior of the tub. If necessary, use the soft brush attachment of a vacuum cleaner.
Fill tub and test for proper operation and leaks. Note: The blower must be plugged into a GFCI protected outlet.

Note: All air baths are equipped with an automatic drying cycle. The blower will turn on for 1-2 minutes approximately 20 minutes after the air system is turned off. This drying cycle cannot be cancelled. Any attempt to cancel this cycle only resets the countdown timer.

INSTALLATION INSTRUCTIONS FOR INTEGRAL SKIRTED TUBS

All MTI BASICS Integral Skirted tubs include an integral molded front skirt and integral three-sided tile flange. These tubs are designed to be installed in a three-wall alcove.

Remove wooden blocks that may be attached to the bottom of the tub, then set tub into installation location. Do NOT drag tub on floor! Level tub at the rim to allow for proper drainage and mark studs at the height indicating level. Provide proper support and maintain level of tub with use of Quikrete, #1103 as a bedding compound. Plaster, sheet rock mud and sand are NOT acceptable wet bedding compounds and will void warranty!
A pre-leveled foam base comes standard on all MTI air baths and is optional for soaker and whirlpools tubs. Pre-leveled foam base negates the need to wet bed on a flat and level surface. Check the sub-floor and tub for level before installing. Quikrete may be used to even out any portion of the sub-floor that is not flat or level.
Carefully drill 1/8” holes through the tile flange at each pre-marked stud location. Secure to stud with screws, being careful not to over-tighten as this might cause the acrylic to crack or chip. Do not attempt to drive nails throught the integral flange. See images below.

FREESTANDING BATH GENERAL GUIDELINES

IMPORTANT: Do not attempt to remove the foam from the bottom of the tub. Doing so may cause damage and will void the warranty. Rough in Dimensions – For critical dimensions, we suggest taking the measurements of the actual tub on site. All printed specifications are +/- ½ inch and subject to change without notice.

Model #	Measurement A	Measurement B
MBCRFS6632	3-3/4”	10”
MBOFS6636	2-3/4”	8”
MBOFSX6636	5-1/2”	11-3/4”
MBXFSX6636	5”	11-3/4”
MBRFSX6636	6”	11-3/4”

Access panel
A removable access panel is located on the drain side of the bath, unless specified without a panel. It provides access for installation of the waste and overflow. It is held in place by covered stainless steel screws.

Fixtures
No fixtures can be mounted on the tub deck of MTI BASICS freestanding tubs. Floor- or wall-mounted fixtures are required. (Except MBOFSX6636, which has an extended deck for mounting a faucet and/or handshower.)

Wall-Mounted
The position of the tub and the reach of the spout are critical. Ensure the spout will extend out far enough to clear the tub flange and the falling water will not hit too high up on the side wall of the tub and splash.

Floor-Mounted
Some freestanding fixtures must be anchored to the tub drain for stabilization. The drain and overflow is concealed under the access cover so anchoring to the overflow pipe (or tub structure) is not possible. Many kits (with minor modification) can be mounted to the wall (rather than the drain pipe) for stabilization.

Virtual Spout
If your tub was ordered with the Virtual Spout tub filler, the tub will fill through the small port on the inner wall of the tub. Incoming water is connected to mixing valves mounted on the wall, or a small platform built adjacent to the tub. Output from the mixing valves must then be tied into the brass Wilkins double check valve, located behind the access panel by the drain. Please check local codes for specific backflow requirements.

INSTALLATION INSTRUCTIONS FOR FREESTANDING TUBS

Determine final location of tub. The tub will sit on top of the finished floor, however, the drain will sit approximately 1/2” – 1 1/2” below the finished floor. Tubs installed on a slab foundation may require extra effort to gain clearance for the drain.
Ensure location is structurally sound, flat and level. See individual specification sheets for tub weights and water capacity.
Remove access panel on rear of tub. Save the screws and screw cap covers for reinstalling later.
Roll tub onto front face being careful not to damage the acrylic finish. Use packing blanket or other suitable material to protect the finish of the tub.
Install waste and overflow. Use 100% clear silicone to seal. Do not use plumbers putty as it may discolor the acrylic or drain finish over time. Plumbers putty can dry and crack, leaving open the opportunity for leaking. Many silicone products will be set in 30 minutes – check product label.
Apply a 3/8” bead of construction adhesive or clear silicone to the bottom of the tub to adhere it to the floor and carefully lower the tub so the drain drops through the floor. The size of the cutout in the floor must allow for the entire drain to clear.
Use care not to allow silicone to get on the outside wall of the tub or surrounding floor area. Wipe any excess immediately with a soft, damp cloth.
From below, connect the drain to the P-trap.
Re-install the access panel using the screws and screw caps saved from step 3.
Water test to ensure bath is leak free. Allow 24 hours before use.

COMPLETING INSTALLATION WITHOUT ACCESS FROM BELOW

Use two 2x4s to elevate the tub above the floor and align the drain with the P-trap. DO NOT LET THE TUB REST ON THE DRAIN PLUMBING.
Apply a 3/8” bead of clear silicone to the underside of the tub to adhere it to the floor. Use care not to allow silicone to get on the outside wall of the tub or surrounding floor area. Wipe off any excess immediately with a soft, damp cloth.
Carefully remove the 2×4 supports and lower the tub so the drain drops into the P-trap adapter. Secure the adapter and re-install the access cover using the screws and screw covers saved from step 3 on previous page.
Water test to ensure bath is leak free. Allow 24 hours before use.

ELECTRICAL INSTALLATION INSTRUCTIONS

Warning: When installing or using electrical products, basic precautions should always be followed, including:

All MTI BASICS whirlpool and air baths require a separate 15 amp 110VAC circuit for each pump or air system blower. The inline heater for whirlpools adds 5.3 amps. The inline heater for air baths and soakers (HTISOAK) will require an additional 20 amp circuit. This circuit must be connected to a supply that is protected by a ground fault circuit interrupter (GFCI). Such a GFCI should be provided by the installer and tested on a routine basis. To test the GFCI, push the test button. The GFCI should interrupt power. Push the reset button. Power should be restored. If the GFCI fails to operate in this manner, there is a ground current flowing, indi-cating the possibility of electric shock. Do not use this unit. Disconnect the unit and have the problem corrected by a qualified electrician before using.
Every MTI BASICS whirlpool or air bath is supplied with a 29” grounded plug on each pump, inline heater or air blower to be plugged into a standard grounded receptacle. Do not remove this plug. If a wall mount switch is desired to control use of the unit, the switch should control the receptacle. Under no circumstance should you alter the provided supply cord.
A pressure wire connector is supplied on the exterior of the pump to permit connection of a No.8AWG (8.4mm) solid copper bonding conductor between this unit and all other electrical equipment and exposed metal in the vicinity as needed to comply with local requirements. NOTE: air blowers do not require a bonding conductor.

IMPORTANT SAFETY INSTRUCTIONS

Pertaining to a Risk of Fire, Electric Shock, or Injury to Persons

DANGER: To reduce the risk of injury, do not allow children or infirmed persons to use this product unless they are supervised at all times.
This MTI BASICS hydrotherapy unit is designed for use only as described in this manual. Do not use attachments not recommended by the manufacturer.
Do not drop or insert any object into any opening.
Do not operate this tub without the guard over the suction fitting (water intake). The guard is a safety device that reduces the potential hazard of hair or body entrapment. Keep hair and body away from suction guard when pump is running.
Anyone under doctor’s care, pregnant, or whose health is poor should check with a physician before using any whirlpool bath system.
Recommended length of hydrotherapy bath is 10 minutes. However, if you become dizzy or nauseous or develop a headache, get out at once and cool down. Get medical attention if symptoms persist. Also check with your physician before using this system again.
Do not use immediately after eating or while under the influence of drugs or alcohol.
Before servicing unit, shut off all electrical outlets as more than one outlet may be energized.

TROUBLESHOOTING Q & A

Q: The pump or blower will not turn on. What should I check first?
A: Check the electrical connections. Test the outlet for power by plugging in a small lamp or hair dryer. Check to make sure the breaker is not tripped. Replace GFCI outlet or breaker if necessary.
Q: There is a leak at the pump when it’s turned on. How do we stop the leak?
A: Check the rubber “O” rings for proper seating. Tighten the large union nut rings on the pump. These may have loosened during shipping or installation. Do not over tighten.
Q: The whirlpool jets do not seem to have much force. How can I adjust?
A: Open the air volume control on the top or side wall of the tub to all for greater air flow through the jets.
Q: One or two of my whirlpool jets are not working. What could be the problem?
A: Each jet can be opened and closed individually. Check each jet by turning the jet escutcheon to ensure it’s open.
Q: How can I check that my in-line heater is working?
A: The in-line heater has a separate power cord. Make sure the pump and heater are both plugged into working receptacles. The indicator light on the top of the heater will glow, indicating it is functioning properly. Keep in mind, the in-line heater will not heat your water; it will just maintain the water temperature up to 103 degrees.
Q: There is a rust colored, greasy ring in my bath tub. What causes this?
A: The condition results from sediment in the water heater of the home. Drain and flush the heater according to the manufacturer’s instructions, and then clean the interior of the tub with a mild, grease cutting dish soap.
Q: The air jets on my tub are not blowing air bubbles. What could be the problem?
A: The on/off control may have been unplugged during installation. Check that the on/off control is connected to the blower, and the blower is plugged into a working receptacle. Check that the grey air hose from the air blower to the manifold is properly connected. If necessary, reconnect and tighten clamps.
Q. My MTI air bath appears to just turn on even if we are not in the tub.
A. Each MTI BASICS air bath is designed to purge 20 minutes after the system is turned off. This is normal, and helps keep the bath dry and sanitary.
Q. I understand the purge cycle, however my tub is now purging in the middle of the night. How can I stop this from happening?
A. Small, barely detectable power fluctuations may have disrupted the purge cycle. Turn the breaker off (or unplug the blower), wait for ten seconds, then plug back in. The blower should now follow the normal purge cycle.
Q: The air bubbles seem cool. How do I check that the blower is warming the air?
A: To verify, turn the air system on high for 4-5 minutes (you do not need to have water in the tub). Carefully feel the grey air hose where it exits the blower. It should be warm to the touch. If it is cold, please contact MTI for service. Please note that some skin sensitive people might experience the so- called “cold air effect”, which is caused by the actual sensation of air bubbles running along the skin, giving the bather a “shivering” sensation. Note: Even if the air entering the tub was hot enough to burn the skin, this shivering effect would still persist. The heated blower is not designed to heat your bath water, just to preheat the incoming air.
If your tub is installed against an outside wall(s), it is recommended to adequately insulate the wall(s) to minimize heat loss. Do not insulate the blower itself; the blower needs sufficient air space surrounding it for proper circulation and operation.
Q: Several of the air jets in my tub are not working. What could be the problem?
A: Some of the air jets may be clogged from normal construction debris, possibly sheet rock dust. To correct: Fill the tub with several inches of warm water. Add 3-4 ounces of CLR. Use only the CLR in the yellow bottle, not the gray bottle. Allow to work for 30 minutes. Using a small brush, such as an old toothbrush, gently brush around each non-functioning jet. Caution! Do not turn the air system on while you have cleaning solution in the tub! Drain and rinse tub. Repeat if necessary.
Q. Can I relocate the pump and/or blower?
A. The whirlpool pump cannot be relocated once the tub is built. The air blower can be relocated on-site up to eight feet away from the bath.
Q. Is it safe to use bath salts or bath oils in my whirlpool?
A. Water soluble products such as bath salts are fine to use, however, MTI does not recommend the use of heavy bath oils. If bath oil is used, refer to the cleaning section of your manual for proper after care and cleaning instructions. Products containing strong natural or chemical dyes may discolor the jets and/or controls on your tub. Check the label to ensure the products are safe for acrylic or plastics, and always use according to the product recommendations.
Q. How can I get scratches out of my acrylic tub?
A. Most scratches can be buffed out using an automotive polish. Any polish suitable for use on “clear coated” automobile paint is fine. Deeper scratches and chips may require the services of a professional acrylic repair technician.
Q. My bath’s hydrotherapy system has been working great for years, and now has stopped working. What should I check first?
A. The problem is most likely the breaker or the GFCI outlet under the tub. Check your breaker box first, and then use a hairdryer to test the outlet under your bath where the equipment is plugged in. This should identify the problem. If both these items check out fine, please have your registration number available and contact our technical service department.
Q. How do I find the serial or registration number on my bath?
A. The registration number can be found on a silver sticker attached to the outside wall of your bath. It is typically placed 3-4 inches over the pump and /or air blower.

WHIRLPOOL AND AIRBATH OPERATING INSTRUCTIONS

WHIRLPOOL

1. MTI BASICS whirlpool baths are equipped with a factory installed on/off device. This eliminates the need for an external switch, although one may have been provided by your install- er. Check with your installer for location of switch. Starting motor with no water in the tub could result in damage to the pump and internal seals and could void your warranty.
Fill tub approximately 1” above highest jet. Do not start pump until tub has been filled to specified level.
When you are ready to use the hydrotherapy system, activate the on/off device on the deck of the tub.
Adjust the amount of air mixed with the water using the master air volume control located on the deck or sidewall of the tub. Rotate the control counter-clockwise to increase the amount of air and pressure in the system.
All jets on MTI BASICS whirlpool baths are designed to operate individually. Open or close jets by twisting the outer ring.
Hydrotherapy jets can also be adjusted directionally.
Bath oils or other petroleum based products are not recommended for use in MTI whirlpool baths. These products have been shown to increase the possibility of bacteria growth within the system.
Bubble bath should only be used sparingly. The action of the system will greatly increase the amount of bubbles. The system must also be cleaned after each use as described in “Cleaning Instructions.”

AIR BATH

MTI BASICS air baths are equipped with a factory-installed on/off device so an external switch is not required. Simply press the on/off button located on the tub to start the air blower.
The air blower has three speeds. The start up speed is high. Pressing the on/off button a second and third time activates the medium and low speeds respectively. The next press will turn the air blower off and activate the delayed purge cycle. The purge cycle will start 20 minutes after the blower is turned off and run for approximately 1-2 minutes. The purge system is designed to dry out the air jets and keep the system clean.

NOTE: The delayed automatic purge is only activated by turning the blower on and off. If the tub is frequently used as a shower or the air system is not used while bathing, it is recommended to manually purge the system. After using the tub and draining completely, briefly turn the system on, then turn off. This will activate the 20 minute delayed purge cycle and keep the system clean and sanitary. Do not touch the on/off button during the purge cycle. Pressing the button will reset the cycle.

CLEANING INSTRUCTIONS

CLEANING INSTRUCTIONS FOR THE ACRYLIC SHELL
The cross-linked cast acrylic surface of all MTI BASICS whirlpools, air baths and soaking baths is among the glossiest, highest quality surfaces available. Its hard, non-porous surface prevents dirt from accumulating and resists stains better than other materials. With normal use, cast acrylic will retain its beauty with only a minimal amount of care. To maintain the high gloss, elegant look of the cast acrylic surface, follow these simple steps:

Use common household, non-abrasive cleaners for most cleaning jobs (for example: a mild dishwashing detergent such as Ivory Liquid). Follow manufacturer’s directions and precau-tions. Rinse well and dry with a soft, clean cloth. Be sure to check the product label. Some products, although not containing abrasives, WILL damage the acrylic over time. Never use any type of “scrubbing bubbles” on your acrylic product unless it specifically states that it is safe for use on acrylic!
Never use abrasive cleansers. If any product feels gritty when rubbed between your fingers, do not use on the acrylic surface or controls as permanent damage will occur.
Do not allow your cast acrylic surface to come into contact with nail polish, nail polish remover, Wintergreen oil, dry cleaning solution, lacquer thinners, gasoline, pine oil, etc.
Remove dust and dry dirt with a soft, damp cloth.
Clean grease, oil, paint or ink stains with isopropyl (rubbing) alcohol. Dry with a clean, soft cloth.
Avoid using razor blades or other sharp objects that might scratch the surface. Small scratch-es can be removed by applying a thin coat of automotive paste wax and buffing lightly with a clean cloth. For deeper scratches, sand the surface lightly with a 400 grit “wet or dry” paper and buff with a fine grit buffing compound.

CLEANING INSTRUCTIONS FOR WHIRLPOOL SYSTEMS

THE WHIRLPOOL SYSTEM SHOULD BE CLEANED PERIODICALLY. MTI WHIRLPOOLS RECOMMENDS CLEANING AT LEAST ONCE A MONTH, NOT TO EXCEED 90 DAYS BETWEEN CLEANINGS.
