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:
WARNING: Risk of personal 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 bath with airjets.
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.
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 bath with airjets.
A pressure wire connector is provided on the exterior of the blower motor 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 bath with airjets 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.
The bath with airjets 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 bath. Disconnect the bath and have the problem corrected by a qualified
service representative before using.
Your new Kohler bath with airjets has been listed by Underwriter’s Laboratories, thus ensuring safety for
you and your family. Your new bath with airjets also conforms to rigid ANSI and IAPMO standards set
within the plumbing industry.

solutions can damage the bath surface.
Do not use abrasive cleansers or solvents on acrylic surfaces. Abrasive cleaners and solvents can
damage the bath surface.
Wipe out your acrylic bath with a soft cloth after each use.
Avoid detergents, disinfectants, or cleaning products in aerosol cans.
NOTE: To restore dull or scratched units: Apply white automotive polishing compound with a clean rag.
Rub scratches and dull areas vigorously. Wipe off residue. Follow with a coat of white automotive paste
wax. Do not wax areas where you walk or stand.
Cleaning Your User Keypad and Remote Control
Use a soft cloth to wipe the keypad and remote control after each use. If the surface becomes dirty,
use a non-abrasive soap and warm water to clean.
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.
