B. Electrical Requirements

'

'''

The installation must have two Class A Ground-Fault
Circuit-Interrupters (GFCI s) or Earth-Leakage Circuit­Breakers (ELCB s). The GFCI s or ELCB s protect
against line-to-ground shock hazard.

Do not relocate
the whirlpool pumps, or make other modifications
to the whirlpool system, as this could adversely
affect the performance and safe operation of the
whirlpool. Kohler Co. shall not be liable under its
warranty or otherwise for personal injury or
damage caused by any such unauthorized
modification.

Use two 220-240
V, 20 A, 50/60 Hz dedicated services; one for each
pump/control/heater system.

WARNING: Unauthorized modification may
cause unsafe operation and poor
performance of the whirlpool.

CUT THE PUMP BANDING STRAPSCUT THE PUMP BANDING STRAPS

IMPORTANT! This step is necessary to make your
Kohler whirlpool operate more quietly.

NOTE:

Use tin snips to cut the two pump banding straps
from each whirlpool pump.

Do not raise the pumps higher than they were
before you cut the pump banding straps. If the pumps
are raised too high, they will not prime properly. Make
sure the rubber isolation feet are in place.

To minimize whirlpool noise and vibration, be sure
the pumps are not in direct contact with the
whirlpool after the pump banding straps are cut. The
pump controls contain rubber isolation feet to
reduce pump noise.

To reduce
the risk of electrical shock, connect the pump to
a properly grounded Ground-Fault Circuit­Interrupter (GFCI) or Earth-Leakage Circuit­Breaker (ELCB). This will provide additional
protection against line-to-ground shock hazard. A
208-240 V, 20 A, 50/60 Hz dedicated circuit is
required.

lubricated, and be in good condition to permit easy
rotation and proper operation of the jet.

Lubricate the O-ring with silicone lubricant to
prevent noisy operation of the jet.
Install the O-ring onto of the jet.
Carefully insert the jet into the housing, and lightly
push and rotate the jet until it snaps into position.

When cleaning up after installation, do not use
abrasive cleansers, as they may scratch and dull the
whirlpool surface. If necessary, use warm water and
a liquid detergent to clean the surface of the
whirlpool, user keypad and remote control.
Remove stubborn stains, paint, or tar with turpentine
or paint thinner.

Remove plaster by carefully scraping with a wood
edge. Do not use metal scrapers, wire brushes, or
other metal tools. Use a powder-type detergent on a
damp cloth to provide mild abrasive action to any
residual plaster.

Do not allow cleaners containing
petroleum distillates to remain in contact with
any whirlpool surfaces for long periods of time.

CAUTION: Risk of product damage.

NOTE:

Do not
submerge the pillows underwater or use them as
seat cushions.

For best attachment to the whirlpool surface,
moisten the back surface of the pillows at the suction
cup locations.

Clean the whirlpool surface of any soap film or oils.
Moisten the suction cups located on the back side of
the pillows. Position the small pillows above the
backjets and above the waterline by pressing down
firmly with the heel of your hand. Check to make
sure that the pillows are attached firmly to the
whirlpool.
Detach the pillows by lifting them off the whirlpool

CONFIRM PROPER OPERATIONCONFIRM PROPER OPERATION

Your whirlpool is equipped with two keypads, each
controlled by its own operating system. Follow the
steps below to confirm the keypads are operating
correctly.

A built-in heater automatically helps to maintain
the water temperature when the whirlpool is running, as
long as the water temperature does not exceed 104 F
