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.
WARNING: 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.
WARNING: 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.
WARNING: Risk of fetal injury. Pregnant or possibly pregnant women should consult a physician
before using the bath.
WARNING: Risk of hyperthermia or drowning. Do not use the bath immediately following
strenuous exercise.
WARNING: 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.
WARNING: Risk of personal injury. Never drop or insert any object into any opening.
Use this bath only for its intended purpose as described in this manual. Do not use attachments not
recommended by the manufacturer.
The bath must be connected only to a supply circuit that is protected by a Ground-Fault Circuit-Interrupter
(GFCI)*. Such a GFCI should be provided by the installer and should be tested on a routine basis. To test the
GFCI, press the test button. The GFCI should interrupt power. Press the reset button. Power should be
restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the GFCI 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.
Your new Kohler bath has been listed by Underwriter’s Laboratories, thus ensuring safety for you and your
family. Your new bath also conforms to rigid ANSI and IAPMO standards set within the plumbing industry.
* Outside North America, this device may be known as a Residual Current Device (RCD).

Bath Features
Door Switch - Used to open the side wall drain. Push the door switch once and the water will
automatically begin to drain after bathing. For faster water removal the toe tap must also be
manually opened. Pushing the switch a second time closes the drain.
Controller - Provides power to the door assembly, switches, level sensors and drain valve.
Handle - Squeeze the handle to lower the door after the seal has fully deflated.
Door - Raise and lower to permit easy movement in and out of the bath. The door also contains an
inflatable seal and electronics to make the bath watertight when the door is raised.
Access Panel - Removable panel that allows access to serviceable components from the front of the
bath.
Receptor Tray - The drip tray collects water from the accumulator drain line and excess water that
escapes over the top of the seal in the door, removing the water through a dedicated drain.
Drain Valve - The drain valve is connected to the side wall drain and is designed to quickly empty
the water from the bath. The bath can be emptied in approximately 2 minutes or less when used
along with the toe tap drain.
Grab Bar - The grab bar is a handhold to assist the bather when entering and exiting the bath.
Toe Tap Drain - Secondary drain that is manually controlled. When used at the same time as the
drain valve, the bath can be emptied in approximately 2 minutes or less.
Overflow - Helps prevent bath from overfilling.
Footwell - Used to temper the water before entering the bath or washing feet with the door
lowered.

Bath Features (cont.)
Accumulator - A small tank located on the back of the bath that produces the sheet flow action
observed while the bath is filling. A small drain line empties the tank to the receptor after every use.
Level Sensors - The sensors monitor the water level in the bath. When the water level is above the
sensors, the door seal will not deflate and the door will not lower.
Heated Surface (if equipped) - Warms your back and neck with adjustable heat.

Operating Your Bath
Using the Bath
NOTE: A removable label is included with the literature packet. It should be applied over the door switch
as a reminder on how to operate the bath.
With the door lowered, turn on the water and adjust it to the desired temperature. The water will
run into the footwell and exit through the sidewall drain and toe tap drain (if open) until the door
is closed.
Enter the bath and close the toe tap drain located in the footwell.
Lightly grasp the handle recess and raise it until the latches on each side of the door engage. The
drain valve will close and the seal will begin inflating.
IMPORTANT! If water does not cover the level sensors within 2 minutes, the drain valve will open
automatically.
Immediately add water to the bath until it is above the level sensors.
Fill the bath until the water is just below the overflow drain.
Exiting the Bath
Push the door switch and open the toe tap drain. The water will drain from the bath in
approximately 2 minutes.
When the water level is below the level sensors, the door seals will automatically deflate. Periodic
cleaning of the sensors will improve response time.
To lower the door, grasp the handle and squeeze while lightly pushing down.
If the bath does not function properly, please refer to the ″Troubleshooting″section.

Maintenance
For best results, perform the following maintenance steps periodically.
•Use a can of compressed air to clean off the seal surface.
•Apply a drop or two of oil to the lower face of the striker plate mounted on either side of the bath.
This is the surface that the latch pins strike when the door is raised. Light oiling will help improve
performance.
•Occasionally wipe off the level probes to keep them clean. This will help improve the system
response time as the water drains from the bath.
•For commercial applications, Kohler Co. recommends periodic maintenance of the door seal by a
Kohler Co. Authorized Service Representative (ASR) or a qualified installer every 3 to 4 years or if
any of the symptoms in the ″Troubleshooting″section occur.
Care and Cleaning
For best results, keep the following in mind when caring for your KOHLER product:
•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.

Normal Operation Includes:
While filling the bath with water, some water is routed to the drip tray and drain through
the accumulator drain hose. It is normal to see or hear a trickle of water either during or
immediately after filling. The accumulator is draining into the drip tray.
It is normal to hear the compressor run for up to 90 seconds after the door is raised. The
compressor is located inside the door and is inflating the door seal.
If the door is fully raised for more than 20 minutes when there is no water in the bath,
the seals will automatically deflate.
It is normal to hear the solenoid valve, located inside the door, open and expel air when
the water level falls below the sensors. The valve is deflating the door seal.
Water coming from the bottom of the door and entering the drip tray is normal when it is
caused by the bather moving about in the bath when it is completely full. Excessive
splashing will cause water to run over the top of the inflated seals into the drip tray.
Water dripping into the drip tray as the seals deflate is normal. Water collects on the seal
during use and runs into the drip tray when the seals deflate.
