ATTENTION INSTALLER: INSTRUCTIONS PERTAINING TO RISK OF FIRE, ELECTRIC
SHOCK, OR INJURY TO PERSONS
READ AND FOLLOW ALL INSTRUCTIONS
SAVE THESE INSTRUCTIONS
WARNING: When using this unit, always follow basic precautions, including the following:
WARNING: RISK OF ELECTRICAL SHOCK.
The unit must be connected only to a 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, there is a
ground current flowing or the GFCI is defective.
The possibility of an electric shock may exist.
DO NOT use this unit. Disconnect the unit and
have the problem corrected by a qualified licensed
electrician.
DANGER: RISK OF INJURY.
Hot whirlpool baths can put certain stresses on the body ,
as do any hot bath, shower, sauna, or steam bath.
Prolonged immersions 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. The
symptoms of hyperthermia include an increase in the
internal body temperature, dizziness, lethargy,
drowsiness, and fainting. The effects of hyperthermia
include: (1) failure to perceive heat, (2) failure to
recognize the need to exit the bath, (3) unawareness of
impending hazard, (4) fetal damage in pregnant women,
(5) physical inability to exit the bath, and (6)
unconsciousness resulting in the danger of drowning.
Warning: The use of alcohol, drugs, or other medication
can greatly increase the risk of fatal hyperthermia.
Grounding is required. The unit should be installed
and grounded by a qualified service representative.
A pressure wire connector is provided on the pump to
permit connection of a solid copper bonding conductor
between this unit and all other electrical equipment and
exposed metal in the vicinity, as needed to comply with
local requirements.
DO NOT operate this unit without the guard on the
suction fitting.
Never drop or insert any object into any opening.
Use this unit only for its intended use as denoted in this
manual. DO NOT use attachments not recommended
by the Kohler Co.

B. PUMP BANDING STRAP CUT
NOTICE: This step is necessary to make your
Kohler whirlpool operate more quietly.
1. Use tin snips to cut the two banding straps. These
banding straps secure the pump to the
whirlpool-mounted shipping bracket. When the
banding straps are cut, the pump base and pump
will drop about 1/2” until they rest on the subfloor . If
the pump drops more than 1/2”, be sure the proper
pitch is maintained (with shims under the motor) to
allow the pump to drain through the suction line
when the whirlpool is drained.
2. If the subfloor is level, no adjustments to the pump
are necessary . Proceed to Step 3. If the subfloor is
not level, slide plywood shims between the pump
base and the subfloor, but only high enough to allow
water to drain out the suction line when the bath is
drained.
NOTE: Do not raise the pump higher than it was before
you cut the banding straps. If the pump is raised too high,
it may not prime properly.
