IMPORTANT SAFETY INSTRUCTIONS
ATTENTION INSTALLER: INSTRUCTIONS PERTAINING TO RISK OF FIRE, ELECTRIC
SHOCK OR INJURY TO PERSONS
READ AND FOLLOW ALL INSTRUCTIONS
WARNING: When using this unit, always follow basic precautions, including the following:
DANGER: RISK OF ELECTRICAL SHOCK.
The installation must have a Class A
Ground-Fault Circuit-Interrupter (GFCI) for the
whirlpool system.
This will provide additional protection against
line-to-ground shock hazard.
Such a GFCI should be provided by the installer and
should be tested on a routine basis.
T o 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.
DO NOT operate this unit without the guard on the
suction fitting.
Never drop or insert any object into any opening.
For -J1 and -JA models only: A green colored terminal
(or a wire connector marked “G”, “GR”, “GROUND”, or
“Grounding”) is provided within the terminal
compartment. To reduce the risk of electric shock,
connect this terminal or connector to the grounding
terminal of your electric service or supply panel with a
conductor equivalent in size to the circuit conductors
supplying this equipment.
All models: A pressure wire connector is provided on
the exterior of the pump or control box within this unit to
permit connection of a No. 8 AWG (8.4 mm2) 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.
Use this unit only for its intended use as denoted in this
manual. DO NOT use attachments not recommended
by the Kohler Co.

11. INSTALL WHIRLPOOL
A. WHIRLPOOL SET -IN
Choose one of the three recommended options below
that is best for your particular installation as described in
1., 2., or 3. Follow the appropriate instructions.
If subfloor is not level, some shimming of the bath and
pump will be necessary. See 11.B. for height
adjustment.
1. Sunken Installation: Set unit into sunken
installation. Make sure the bath/whirlpool is level
and is resting on all blocks. Insert the tailpiece into
the trap. Apply a bead of RTV sealant under rim of
the bath unit.
2. Install Using Gypsum: Place a 2” thick layer of
gypsum cement (such as Gyp-Crete 2000) on the
floor where the whirlpool is to be set. This will help
secure, level and support the bath. Set bath into
position. Clear any excess cement from vicinity of
the pump.
NOTE: Pump bracket must sit flat on the floor.
Insert tailpiece into trap. Make sure bath is level
and resting on all supporting blocks.
3. Install Using 1 x 2 Strips: Set whirlpool in desired
location and level. Nail 1 x 2 wood strips around
blocks under the whirlpool to firmly hold it in
position. It is not necessary to use strips on all
blocks. They are only needed on blocks that are to
the outside edges of your installation.
Insert tailpiece into trap. Make sure bath is level and
resting on all supporting blocks.

Shim if necessary, using 5” x 7”
(minimum) plywood
C. SECURE WHIRLPOOL
Using four 1/4” x 1” lag screws, secure pump bracket to
subfloor. Predrilling is recommended.
CAUTION: Risk of product damage. Do not
use the piping or pump for structural support or
positioning of whirlpools.
Use a 1/2” wrench to remove the long bolt securing the
bracket to the bath.
D. INST ALL PLUMBING
CAUTION: Risk of damage to whirlpool
bottom and subfloor. Ensure watertight seal on
bath drain connections.
1. When whirlpool is securely positioned, connect
drain into trap. An access panel will simplify future
maintenance.
2. Install the faucet valving and spout tee. If faucets
are deck-mounted, the deck must be finished
before handle trim and spout can be installed. Open
hot and cold valves and check all supply
connections for leaks.
