Install the Bath
CAUTION: Risk of damage to the product. The weight of the bath must be supported by the adjustable feet of the bath.
IMPORTANT!
- Do not lift the bath by the fittings, drain, and pipe. Lift only by the metal frame.
- Do not damage the adjustable feet by dragging or sliding the bath across the floor.
- To prevent product damage while moving the bath, verify that the adjustable feet are fully extended to raise the bottom of the bath apron off the floor. Use a wrench to fully extend the adjustable feet, if necessary.
NOTE: To prevent the apron plate from directly touching the ground and being pressed, the height of the apron plate above the ground must be at least 5 mm.
- If the subfloor is not level, make repairs as necessary. Verify that the subfloor is level.
- Unpack the bath, and check for any transit damage before installation.
- Place the bath in an appropriate position.
- Adjust the leveling feet at the bottom of the bath, and verify that the bath is level.
- Tighten the nuts of the leveling feet to set the height of the bath.
Install the Drain Hose
CAUTION: Risk of property damage. Verify that a watertight seal is installed on the bath drain.
NOTE: Use the kit flexible hose if the drain outlet is close to the drain; if the drain outlet is far from the drain, use the kit flexible hose extend.
- Install the recommended faucet (23490T-4-CP or 31236T-4-CP) according to the manufacturer’s instructions.
- Install the drain (supplied) according to the manufacturer’s instructions.
- Determine the length of the drain hose based on the location of the bath and the floor drain, then select kit flexible hose or kit flexible hose extends and seal the connection with silicon.

Clean-up after Installation
When cleaning up after installation, do not use abrasive cleaners as they may
scratch and dull the surface. Use warm water and liquid, nonabrasive detergent
to clean the surface.
Stubborn stains, paint, or tar can be removed with mineral spirits. Do not use
cleaners containing solvent. Plaster can be removed by scraping with wood
edge. Do not use metal scrapers, wire brushes, or other metal tools. One of
the powder-type detergents may be used on a damp cloth to provide mild
abrasive action to the residual plaster.

Important Safety Instructions
READ AND FOLLOW ALL INSTRUCTIONS
SAVE THESE INSTRUCTIONS
INSTRUCTIONS PERTAINING TO A RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO
PERSONS
WARNING: When using electrical products, basic precautions should always be followed, including the following:
DANGER: Risk of accidental injury or drowning. To reduce the risk of injury, do not permit children to use this unit unless they are closely supervised at all times.
WARNING:
- Risk of personal injury. To avoid injury, exercise care when entering or exiting the bath.
- Risk of electric shock. Do not permit electric appliances (such as a hair dryer, lamp, telephone, radio, or television) within 5’ (1.5 m) of this bath.
- The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia. 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 an increase in the internal temperature of the body, dizziness, lethargy, drowsiness, and fainting. The effects of hyperthermia include: (a) failure to perceive heat, (b) failure to recognize the need to exit the bath, (c) unawareness of impending hazard, (d) fetal damage in pregnant women, (e) physical inability to exit the bath, and (f) unconsciousness resulting in the danger of drowning.
- Risk of fetal injury. Pregnant or possibly pregnant women should consult a physician before using the bath.
- Risk of hyperthermia or drowning. Do not use the bath immediately following strenuous exercise.
- Risk of hyperthermia or drowning. Water temperature in excess of 100°F (38°C) may cause injury. Test and adjust the water temperature before use.
- Risk of personal injury. Never drop or insert any object into any opening.
- Risk of hyperthermia. People using medications and/or having an adverse medical history should consult a physician before using a whirlpool equipped with a heater.
CAUTION: Risk of personal injury. To reduce the risk of injury, people with infirmities should not be allowed to use this product without close, continuous supervision.
- Use this bath only for its intended purpose as described in this guide. Do not use attachments not recommended by KOHLER Co.
- The bath must be connected only to a supply circuit that is protected by a Residual Current Device (RCD). Such an RCD should be provided by the installer and should be tested on a routine basis. To test the RCD, press the test button. The RCD should interrupt power. Press the reset button. Power should be restored. If the RCD fails to operate in this manner, the RCD is defective. If the RCD interrupts power to the bath without the test button being pressed, a ground current is flowing, indicating the possibility of an electric shock. Do not use this bath. Disconnect the bath and have the problem corrected by a qualified service representative before using.
- Flush your whirlpool system twice a month or more depending upon usage, as described in the “Flush the System” section of this guide.
- Do not operate this unit without the guard (cover) over the suction fitting.
- Repeated use of personal care products containing oils can damage plastic whirlpool components. Avoid using bath oils.
- Whirlpool hydromassage action can cause even a small amount of bubble bath, bath soap, shampoo, or bath oil to foam excessively. For this reason, do not use these products during whirlpool operation.
Operating the Air System
- Press once for high flow.
- Press a second time for medium flow.
- Press a third time for low, “Back Only” flow.

- Run the whirlpool system for 5 to 10 minutes.
- Turn off the whirlpool system and drain.
- Rinse the surfaces of the bath, jets, faucet, handrails, and drain. Wipe dry with a soft cloth.
Care and Cleaning
For best results, keep the following in mind when caring for your KOHLER bath:
- Always test your cleaning solution on an inconspicuous area before applying to the entire surface.
- Wipe surfaces clean and rinse completely with water immediately after applying cleaner. Rinse and dry any overspray that lands on nearby surfaces.
- Do not allow cleaners to soak on surfaces.
- Use a soft, dampened sponge or cloth. Never use an abrasive material such as a brush or scouring pad to clean surfaces.
- The ideal cleaning technique is to rinse thoroughly and blot dry any water from the surface after each use.
- Use a soft nylon brush on slip-resistant surfaces. Be sure to use a water-soluble cleaner (dissolves 100% in water).
- Do not use powdered cleaners unless the cleaner is fully dissolved in water. Solid substances can block the airjets.
- Do not use full strength bleach or ammonia cleaning solutions. Chemically active cleaning solutions can damage the surface.
- Do not use abrasive cleansers or solvents on airjet surfaces. Abrasive cleaners and solvents can damage the airjet surface.
Maintaining the Airjets
- If cleaning the airjets is required due to hard water deposits, use a small between-the-teeth dental brush and white vinegar. Dip the brush in the vinegar, brush the hole, rinse the brush in clean water, and then use the wet rinsed brush to rinse the hole.
- Fill the bath with water to the top row of airjets. Drain the bath, and press the air system button to purge retained water from the air system. Press the air switch button three more times to turn off the air system.
Important Consumer Information
Consumer Responsibilities
Cleaning Acrylic Surfaces: Do not use abrasive cleansers on any acrylic
surfaces, as they will scratch and dull the surface. Wipe out the bath after
each use to prevent a build-up of soap and scum. If the acrylic surface
becomes dull, an automotive type rubbing compound may be used on the unit,
followed by an application of paste wax.
- KOHLER Co. recommend: Rubbing compound Mequiars Mirror Glaze 28 metal polish (import product) or “green oil.”
