C. 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
bath-mounted shipping bracket. When thebanding
straps are cut, the support bracket 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
notlevel,slide plywood shims between the support
bracket 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

D. INSTALL PLUMBING
CAUTION: Risk of damage to bath bottom and
subfloor. Ensure a watertight seal on the bath
drain connections.
1. When the bath is securely positioned, connect the
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.
12. 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.
B. WIRING INFORMATION – 120 V, 60 HZ –
1-SPEED PUMP (UL LISTED) MODELS
WARNING: Risk of electrical shock. To reduce
theriskofelectricshock,connectonlytoaproperly
grounded, grounding-type receptacle, protected
by a Ground-Fault Circuit-Interrupter (GFCI). Do
not remove the plug’s grounding pin. Do not usea
grounding adapter.
Your Kohler whirlpool bath is equipped with a cord and
plug. All wiring of the pump and control has been
completed at the factory. A licensed electrician must
install a GFCI-protected, 120 V, 15 A, grounded outlet.
Your whirlpool may then be plugged into this outlet. No
other load should be on this circuit. Locate the outlet
behind the whirlpool, and within 24” of the pump.
NOTE: Be sure the air actuator tubing is securely
attached to the pump. Ensure that it is not kinked or
damaged.

15. COMPLETE INSTALLATION
A. INSTALL HANDLES AND SPOUT
Install the faucet handles and spout according to the
manufacturer’s instructions. Seal around the plumbing
fittings.
16. CLEAN-UP AFTER INSTALLATION
When cleaning up after installation, do not use
abrasive cleansers as they may scratch and dull the
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
plaster.
17. CONFIRM PROPER OPERATION

A. FLEXJET INSTALLATION
NOTE: The Flexjet O-ring must be correctly positioned,
must be lubricated, and must be in good condition to
permit easy rotation and proper operation.
1. Install the O-ring onto the first shoulder of the
Flexjet. Lubricate the O-ring with silicone lubricant
to prevent noisy operation of the Flexjet.
2. Insert the Flexjet into the housing, and lightly push
androtatethe Flexjetuntil itsnapsintoposition.Do
not force the Flexjet.
NOTE: When installed correctly, the Flexjet should turn
smoothly both clockwise and counterclockwise.
