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
havetheproblemcorrectedby aqualifiedlicensed
electrician.
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.
DANGER: RISK OF INJURY.

temperatureofthebodyreachesalevelseveraldegrees
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
impendinghazard,(4)fetal damageinpregnantwomen,
(5) physical inability to exit the bath, and (6)
unconsciousness resulting in the danger of drowning.
Warning: Theuseofalcohol,drugs,orothermedication
can greatly increase the risk of fatal hyperthermia.

Construct a minimum 2x4 recess designed for your
particular installation. Make sure you allow for access to
the pump in the event the unit requires service. When
constructing the framing, allow for the thickness of sub
and finish wall materials.
If an apron wall without a ledge is desired, the finished
apron wall surface must be 1/16” under the bath rim.
The whirlpool can be installed in a corner. Recess or
sunken installations are also possible. Steps 1. through
3. below illustrate suggested stud construction.
Modifications may be needed for other types of
construction.
1. Corner Installation: The suggested stud
construction is illustrated.
2. Recess Installation: The suggested stud
construction is illustrated.

B. PARTIALLY INSTALLBATHDRAIN
Install the whirlpool drain according to the drain
manufacturer’s instructions. Do not connect the trap at
this time.
C. PROTECT WHIRLPOOL UNIT
Position a drop cloth or similar material in the bottom of
the unit. Be careful not to scratch the surface of the
product.
7. INSTALL THE WHIRLPOOL
A. WHIRLPOOL SET-IN
CAUTION: Risk of product damage.Donotuse
the piping or pump for structural support or
positioning.
Option For Corner or Recessed Installation: Slide
the new whirlpool into position. Insert the drain tailpiece
into the trap. Level the whirlpool by placing metal shims
under the whirlpool feet, as needed. The whirlpool must
belevelandrestingonallfourfeet.Checkforlevelalong

Option For Sunken Installation: Set the bath into the
sunken installation. Make sure the unit is level and
resting on all support feet. Insert the drain tailpiece into
the trap. Apply a bead of silicone sealant under the rim
of the unit.
CAUTION: Risk of product damage. Do not
hang the unit by the rim. Whirlpool Rim

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

3. To minimize bath noise and vibration, be sure the
pump is not in direct contact with the shipping
bracket after the banding straps are cut. The pump

drain to the trap.
NOTE: An access panel will simplify future mainte-
nance. Connect Here
2. Install the faucet valving and spout tee. Open the
hot and cold water valves, and check the supply
connections for leaks.
3. Run water into the bath, and check the drain
connections for leaks.
8. INSTALL GRIP RAILS
Refer to the installation instructions packed with thegrip
rail kit when installing the grip rails.
9. ELECTRICAL CONNECTIONS
A. IDENTIFY ELECTRICAL REQUIREMENTS
The model number is printed on a label at the pump end
of the whirlpool.
The label identifies electrical rating.

bath surface. Use warm water and a liquid detergent to
clean the surface.
Stubborn stains, paint, or tar can be removed with
turpentine or paint thinner. Do not allow cleaners
containing petroleum distillates to remain in
contact with whirlpool surfaces for long periods of
time. Plaster can be removed by scraping with a wood
edge. Do not use metal scrapers, wire brushes, or other
metal tools. A powder-type detergent may be used on a
dampclothtoprovidemildabrasiveactiontotheresidual
