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: 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.
Use this whirlpool only for its intended purpose 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 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.
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.
IMPORTANT! Flush your whirlpool system twice a month or more depending upon usage, as described
in the ″Flushing Your Whirlpool System″section of this manual.
Do not allow the water temperature in the whirlpool to exceed 104°F (40°C).
Keep small objects such as bath toys and bathing accessories out of the whirlpool while the unit is running.
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:
Bath - Acts as a reservoir for water, and provides a location for the hydro-massage action.
User Keypad - Located within easy reach, the keypad 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.
Pump Motor - Provides quiet, variable speed power to circulate the water and create the soothing
hydro-massage action.
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 - Designed to automatically help maintain the temperature of the water up to 104°F (40°C) to
enhance your hydro-massage experience. The heater turns on automatically when the whirlpool is
operating, and turns off when the pump motor is turned off. The heater may be turned off, through
the keypad, at any time while the pump is operating.
Neckjets and Pillow - Delivers 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. Neckjet operation is controlled through the
user keypad.
Backjets - Delivers 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.

Troubleshooting Procedures
Remove the Jets
NOTE: A special tool is provided with the jets that will allow you to remove them from the whirlpool.
This tool is also supplied with each trim kit.
Position the jet ball nozzle so it is pointing upward.
NOTE: The nozzle must remain pointed up or the tool will slip off.
Insert the removal tool, hooked end up, into the opening of the jet and hook the inside top of the
nozzle.
Grasp the tool firmly and place your thumb against the whirlpool wall. Pull steadily on the tool
until the jet assembly pulls free of the hole. Be careful not to lose the O-ring.
Reinstall the Jets
NOTE: The jet O-ring must be correctly positioned, must be lubricated, and must be in good condition to
permit easy rotation and proper operation of the jet.
Install the O-ring onto the first shoulder of the jet. Lubricate the O-ring with silicone lubricant to
prevent noisy operation of the jet.
Carefully insert the jet into the housing, and lightly push and rotate the jet until it snaps into
position. Do not force the jet.
NOTE: When installed correctly, the jet should turn smoothly both clockwise and counterclockwise.
