Installation and Operational Manual·Reliance® Tubs
Important Safety Instructions
This manual contains information and instructions for proper handling, operation and maintenance of your MTI bathtub. Failure to follow these instructions could result in personal injury, electrical shock or fire.
WARNING: When using electrical products, basic precautions should be followed, including the following:
· Do not permit children to use this unit unless they are closely supervised by an adult at all times. Supervision is also required when bath is used by an elderly or handicapped individual.
· Never leave a full or filling bath unattended. · Use this unit only for its intended use as described in this manual. Do not use attachments not recommended by the manufacturer.
Never drop or insert any object into any opening. · Do not operate this unit without guard over the suction fitting. · The water in a bath 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. Usage 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. If symptoms are experienced, get out immediately and cool down. Seek medical attention if symptoms persist, and check with physician before using the system again. 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 water temperatures to 38° C (100° F). · The use of drugs or alcoholic beverages before or during bathing may lead to unconsciousness with the possibility of drowning. Never use the bath while under the influence of alcohol, anticoagulants, stimulants, antihistamines, vasoconstrictors, vasodilators, hypnotics, narcotics or tranquilizers. · Persons using medication or that have a medical history of heart disease, have had a recent surgical procedure, and/or have low or high blood pressure, circulatory system problems, or diabetes should consult a physician before using a bath or hydrotherapy tub. Medication may induce drowsiness while other medications may affect heart rate, blood pressure and circulation.
DANGER
· To reduce the risk of injury, enter and exit the bath slowly. · Never operate electrically connected devices in or within 5' of the bath. Never drop or insert any object into any opening within the bath. · 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 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. If 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 material surface, the inlet water temperature should not exceed 60° C (140° F). · Disconnect power before servicing as more than one outlet may be energized.
A pressure wire connector is provided on the exterior of the pump or control with 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.
INSTALLER/OWNER BEARS ALL RESPONSIBILITY TO COMPLY WITH ALL STATE AND LOCAL CODES WHEN INSTALLING THIS PRODUCT.

Below are instructions for drain installation of any Reliance® tub. Freestanding tubs are designed to install on top of the finished floor. Many freestanding models come with an access panel behind the waste and overflow for ease of installation. Most tub models, whether freestanding or drop-in, require access from below to finalize drain installation. If there is no access from below, the installation can be more difficult. Some Reliance tubs are designed to accommodate an above-the-floor drain installation. Check product specification sheet for details.

With Access From Below (Recommended)
1. Install drain on tub. Dry fit to properly-sized drain pipe. Apply clear silicone under waste flange.
2. Set tub² and connect drain from below floor. Make sure tub drain aligns with rough-in and secure to P-trap.1
3. Fill tub to overflow, allowing water to stand for 30 minutes. Check carefully for any leaks.
NOTE: Allow time for silicone to cure before water testing. Many products are ready to test in as little as 30 minutes. Refer to product label for details.
4. Allow silicone to dry 24 hours before regular use.

Without Access From Below
1. Stub out drain and P-trap with 1 1/2 schedule 40 PVC pipe at least 1" above finished floor. Trim waste pipe to proper height.
2. Box out around the pipe to allow trimming this pipe below grade upon installation.
WARNING: DO NOT let tub rest on drain plumbing.
3. Before setting tub, prepare waste pipe and drain fitting with PVC cement. Make sure tub drain, gasket and flange align with rough-in.
4. Set tub² and connect drain.1
NOTE: 2x4s may be used to lower freestanding tub to finished floor.
5. Fill tub to overflow, allowing water to stand for 30 minutes. Check carefully for any leaks.
6. Allow silicone to dry 24 hours before use.

Installation and Operational Manual·Reliance® Tubs
Plumbing Installation Instructions
Access panel comes standard on tub models with integral faucet deck and optional virtual spout.
Deck Mounted Valves
1. Tub material may be drilled using carbide hole saw. 2. Mark the planned location of each valve on the faucet deck. 3. On freestanding tubs, install valves on integral faucet deck through access panel. See valve manufacturer's installation instructions.
If the freestanding tub has an integral faucet deck and does not have an access panel, tub is designed for valve installation from underneath. Be sure to protect the tub shell when gaining access to the underside of the tub.
BEFORE DRILLING: Dry fit valve trim to ensure proper fit and clearance.
4. MTI recommends the use of braided stainless steel supply lines for best fit between the walls of a freestanding tub. 5. Water test all supply line and valve connections for leaks prior to final installation.¹
Virtual Spout Connection
Optional Virtual Spout is factory installed in the tub wall and intended for use as a tub filler in lieu of a traditional faucet or filling spout. Mixing valves are not supplied with the Virtual Spout. The Virtual Spout is installed below the water level of the tub. Special consideration is needed to prevent backflow into the fresh water supply. The Virtual Spout comes with a Wilkins Dual Check Valve² installed inline to prevent backflow (Fig. 2). A Cash Acme® in-wall vacuum breaker³ ships with all tubs ordered with the Virtual Spout. The provided vacuum breaker requires access through the wall and a spill tray. Some areas of the country require additional backflow prevention above the water line of the tub (Fig. 3). Check local codes, as some areas of the country require a deck-mounted backflow prevention device. 1. MTI recommends the use of braided stainless steel supply lines between the walls of a freestanding tub for best fit of customer-
supplied mixing valves. 2. Tee the hot and cold supply lines before connecting to the stub out on the tub 3. Connect mixed supply line to the Wilkins dual check valve that is factory installed between the walls of the tub. Access panel behind
drain location on freestanding tubs facilitates connection to Virtual Spout stubout. If the freestanding tub does not have an access panel, stubout is accessible underneath the tub. Be sure to protect the tub shell when gaining access to the underside of the tub. 4. Water test for leaks all supply line and valve connections prior to final installation.

Drop-In / Undermount / Alcove Installation Guidelines
Measure actual tub prior to building any structure(s) for the tub. All printed specifications for MTI tubs have ± ½" tolerance and are subject to change at any time. MTI Baths, Inc. is not responsible for any preparatory labor or material charges. Additional access to plumbing fixtures is strongly recommended. It is the responsibility of the installer to provide access to pump and plumbing in compliance with local plumbing codes.

Important Tub Measurements

Some installations may require different methods than the following instructions. However, framing should always provide a level surface for the rim of the tub in both directions and sufficient space for bedding compound underneath the full length of the tub (G). Never let the rim of the tub bear the weight of the tub.

MTI tubs are not equipped with leveling feet. MTI recommends Quikrete #1103 sand/topping mix or equivalent as bedding compound.¹ Plaster or sheet rock mud are NOT sufficient bedding compounds.

NOTE: Airbaths and tubs equipped with optional pre-leveled frame and foam base negate the need to wet bed when installing on a flat and level surface. Foam base adds 2"-3" to the overall height of a drop-in/undermount tub (F).

IMPORTANT: Plan for access to each pump, blower and/or electrical component. DO NOT allow any material such as insulation within 8" of pump. Pump and blower must have sufficient air space surrounding them for circulation.

Alcove / Skirted Tub Installation
1. Remove any wooden blocks from under tub prior to install.
2. Level tub at the rim in both directions (front-to-back and side-to-side), leaving 1/2"-1" void under tub for bedding compound.
3. Mark level line on stud walls at tub height (C).
4. Install top of stringer at the marked line. Construct frame across the front of the tub at the same height as the stingers for skirt, tile or other material.
5. Install drain components per manufacturer's instructions. General drain installation guidelines can be found in this manual on pg. 8.
6. Prepare wet bed, unless tub is equipped with optional factory-installed foam base and is being installed on a flat and level surface (a small amount of thin-set is recommended to level uneven floor).
7. Before bedding sets, carefully work tub into it, shifting side-to-side, until tub is in planned level position. Use care not to damage any plumbing, electrical components or wiring when moving and bedding the tub. NOTE: Tub will not drain properly if not leveled at the rim.
8. Drill 1/8" pilot holes through the tile flange at each stud location. Shim as needed. Secure tile flange to stud wall with screws. DO NOT use nails.

Leveling Stringers

Provide an opening of at least 16" x 14" for pump access. Font access available on select MTI skirt styles.

Drop-In / Undermount / Alcove Installation Guidelines (continued)
IMPORTANT: Plan for access to each pump, blower and/or electrical component. DO NOT allow any material such as insulation within 8" of pump. Pump and blower must have sufficient air space surrounding them for circulation.
Drop-In / Framed Box Installation
Opening should be no less than 1"-1½" smaller than the exterior dimensions (A) and (B) of the tub deck.
NOTE: It is best to have as large an opening as possible to clear the plumbing and other system components. Full size templates available from MTI for oval and odd shaped tubs.
1. Construct level framing at proper drop-in tub height plus ½"1" for wet bedding compound (C). If tub is equipped with factory-installed pre-leveled foam base, use height (D).¹
IMPORTANT: The bottom of the tub must be fully supported with bedding compound (G). Under no circumstances should the tub "hang" by the top flange.
2. Level subfloor with floor leveling compound or thin-set before installing frame.
3. When floor leveling compound is dry, secure frame to the floor and any surrounding stud walls before setting tub.
4. Install drain components per manufacturer's instructions. Drain installation guidelines can be found in this manual on pg. 8.
5. Prepare wet bed for entire length of tub (G), unless tub is equipped with factory-installed foam base.
6. Set tub, shifting side-to-side, until it is in planned level position. Use care not to damage any plumbing, electrical components or wiring when moving and bedding the tub. NOTE: Tub will not drain properly if not leveled at the rim.

Undermount / Framed Box Installation

MTI does not make recommendations as to the size and shape of the opening for undermount installation. Do NOT use
any templates supplied by MTI for undermounting. Template actual tub bowl dimensions very carefully before building or
cutting any deck materials. MTI Baths, Inc. is not responsible for any preparatory labor or material charges.
1. Construct level framing at overall tub height plus ½"1" for wet bedding compound (E). If tub is equipped with factory-installed pre-leveled foam base, add 2"3" for foam base to measurement (F). At the proper height, the top of the frame will be even with the tub deck on a level surface.¹

2. Construct additional framing around the tub to support the weight

of overhanging tile/deck material. If using solid surface material

that covers only the width of the tub flange, additional support is

not necessary. 3. Level subfloor with floor leveling compound or thin-set before

Measure from the top of the tub deck to level floor for frame height

Care and Cleaning Instructions -- Acrylic CXLTM
About the Acrylic Shell
Cast acrylic is a stain-resistant, non-porous material. With normal use, the acrylic will retain its inherently glossy appearance with only a minimal amount of care.
When Cleaning
· Remove dust and dry dirt with a soft, damp cloth. · Apply common household, non-abrasive cleaner in accordance with manufacturer's directions and precautions.
(i.e., a mild dishwashing detergent such as Ivory Liquid). Do not use unless the product label specifically states that it is safe for acrylic. · Rinse well and dry with a soft, clean cloth. Scouring pads will deteriorate the finish. · Never use any type of "scrubbing bubbles" or aerosol spray cleaners on your acrylic product. · Harsh chemicals, such as bleach and ammonia, will deteriorate the finish. · Never use abrasive cleansers. If any product feels gritty when rubbed between your fingers, do not use on the acrylic surface or
system controls as permanent damage will occur. WARNING: Check cleaning and bathing product labels. Do not use unless the product label specifically states that it is safe for acrylic.
Some non-abrasive products damage the acrylic over time.
General Care
· 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.
· Avoid using razor blades or other sharp objects that might scratch the surface. · Small scratches can be removed by applying a thin coat of automotive polishing liquid 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. · MTI strongly recommends a professional surface repair person for deep scratches, chips or gouges. · Damage occurring to the unit during installation is the responsibility of the installer, and after installation, the responsibility of the user.

Installation and Operational Manual·Reliance® Tubs
Troubleshooting
Q: The pump or blower will not turn on. What should I check first? A: Check the breaker and reset GFCI receptacle. A hairdryer or low-voltage lamp may be used to test the outlet. If operation is not restored, contact MTI for support. 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 nuts on the pump. Do not over tighten. Q: The whirlpool jets do not seem to have much force. How can I adjust? A: Twist open the air volume control on the top or side wall of the tub. Q: How can I check that my in-line heater is working? A: The indicator light on the top of the heater will glow when it is functioning properly. The in-line heater is designed to maintain bathing water temperature (not to exeed 104ºF) and will not heat cold or cool water. 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: Some or all of the air jets on my tub are not blowing air bubbles. What could be the problem? A: Some of the air jets can become clogged from construction debris, such as sheet rock dust, during installation. Fill the tub with several inches of warm water. Add 34 ounces of CLR. Use only the CLR Bath Cleaner, not other CLR products. Let stand for 30 minutes. Using a small soft brush, gently clean each non-functioning jet. DANGER! Rinse thoroughly. Do not turn on the air system with cleaning solution in tub. Always wear proper eye protection when using caustic chemicals. Follow product label safety precautions. Q: The air bubbles seem cool. How do I check that the blower is warming the air? A: The heated blower is designed to preheat the incoming air and will not heat the bath water. It is recommended to adequately insulate the wall(s) against which the tub is installed in order to minimize heat loss. Do not insulate the blower; sufficient air space is required for proper circulation and operation. Turn the air system on high for 45 minutes to verify the air is warm (you do not need to have water in the tub). Carefully feel the PVC pipe at the blower nozzle. It should be warm to the touch. If it is cold, contact MTI for support. Q: Is it safe to use bath salts or bath oils in my air bath? A: Water soluble products such as bath salts are fine to use. Avoid bath bombs that contain glitter. Use of bath oils is not recommended. If bath oil is used, refer to the cleaning section of the manual for proper cleaning instructions. Products containing natural or chemical dyes may discolor the jets and controls. Always use bath products according to the product label. Q: How can I get scratches out of my tub? A: Most scratches can be buffed out using readily-available and easy-to-use products (see Care and Cleaning section for more repair information). Deeper scratches and chips may require the services of a professional repair technician. Q: How do I find the serial or registration number on my bath? A: The registration number can be found on a silver sticker adhered to the backrest 3-4 inches above the motor location.
