Important Information
INSTRUCTIONS PERTAINING TO A RISK OF FIRE,
ELECTRICAL SHOCK, OR INJURY TO PERSONS
READ AND FOLLOW ALL INSTRUCTIONS
SAVE THESE INSTRUCTIONS
WARNING: When using electrical products, basic precautions should always be followed,
including the following:
DANGER: Risk of personal injury. 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
whirlpool.
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 whirlpool.
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 hyperthermia. People using medications and/or having an adverse medical
history should consult a physician before using a whirlpool equipped with a heater.
WARNING: Risk of scalding. Do not allow the water temperature in the whirlpool to exceed 104°F
(40°C).
The heater will automatically maintain the water temperature when the whirlpool is running, as long as the
water temperature does not exceed 104°F (40°C). The heater will disengage at higher temperatures.
An equipment grounding terminal is provided in the field wiring compartment. To reduce the risk of electric
shock, this terminal must be connected to the grounding means provided in the electric supply panel with a
conductor equivalent in size to the circuit conductors supplying this whirlpool.
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.
Use this whirlpool only for its intended purpose as described in this guide. Do not use attachments not
recommended by the manufacturer.
Never drop or insert any object into any opening. Keep small objects such as bath toys and bathing
accessories out of the whirlpool while the unit is running.
Do not operate this unit without the guard (cover) over the suction fitting.
The whirlpool must be connected only to a supply circuit that is protected by a Ground-Fault
Circuit-Interrupter (GFCI) or Residual Current Device (RCD). Such a GFCI or RCD should be provided by
the installer and should be tested on a routine basis. To test the GFCI or RCD, press the test button. The
GFCI or RCD should interrupt power. Press the reset button. Power should be restored. If the GFCI or RCD
fails to operate in this manner, the GFCI or RCD is defective. If the GFCI or 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 whirlpool bath. Disconnect the whirlpool 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
System″section of this guide.
Repeated use of personal care products containing oils can damage plastic whirlpool components. Do not use
heavy, vegetable-based shampoos or bath oils.
Whirlpool hydro-massage action can cause even a small amount of bubble bath, bath soap, shampoo, or bath
oil to foam excessively. For this reason, please don’t use these products during whirlpool operation.

Your Kohler Whirlpool
Your new whirlpool is designed to stimulate, invigorate, and energize your body with comforting
hydro-massage therapy. The whirlpool consists of the following components:
Lighted User Keypad - Located within easy reach, allows you to turn the whirlpool on and off. It
also allows you to access all the whirlpool modes and regulate the water flow or pulse speed.
Remote Control - Places the whirlpool functions at your fingertips to further enhance your bathing
experience. The functions of the remote control are identical to the lighted user keypad.
Pump Motor - Provides quiet, variable speed power to circulate the water.
Adjustable Jets - Positioned to optimize their hydro-massage effect, the jets allow you to adjust the
air and water flow and control the flow direction as you desire.
Heater - Automatically helps maintain a 104°F (40°C) water temperature, turns on when the
whirlpool is operating, and turns off when the pump motor is turned off. Using the lighted user
keypad, the heater may be turned off at any time while the pump is operating.
Effervescence - Eight effervescent ports emit thousands of champagne-like bubbles which provides a
relaxing, soothing experience.
Chromatherapy - Promotes relaxation and delivers a full spectrum of color. Chromatherapy may be
used with all modes of operation, even when the pump is not operating.
Neckjets and Pillow - Controlled through the user keypad, the neckjets deliver massaging water to
the back of your neck. The pillow provides a comfortable place to rest your head as you relax. To
prevent water spills, a built-in switch stops the neckjet action if the pillow is removed during
operation.
Backjets - Controlled through the user keypad, the backjets deliver massaging water to your back.
The backjets pulse from the bottom of the whirlpool toward the top, with water flow and pulse
action occurring from two backjets at a time.
