This will help secure, level, and support the unit. Clear all the material away from the pump control
and support block locations.
NOTE: Do not use gypsum cement or drywall compound for this application, as they will not provide an
acceptable, durable bond.
NOTE: The pump control (when the pump banding straps are cut) and support blocks must rest
directly on the subfloor.
Position a piece of plastic drop cloth material on top of the cement or mortar bed. With help,
carefully lift the whirlpool into place, and make sure the pump control and support blocks do not

5. Cut the Pump Banding Straps
IMPORTANT! This step is necessary to make your Kohler whirlpool operate more quietly.
Use tin snips to cut the two pump banding straps from the whirlpool pump.
NOTE: Do not raise the pump higher than it was before you cut the pump banding straps. If the pump is
raised too high, it will not prime properly. Make sure the rubber isolation feet are in place.
To minimize whirlpool noise and vibration, be sure the pump is not in direct contact with the
shipping bracket after the pump banding straps are cut. The pump control contains rubber isolation
feet to reduce pump noise.
6. Install the Plumbing
CAUTION: Risk of property damage. Ensure a watertight seal on the whirlpool drain.
Connect the drain to the trap according to the drain manufacturer’s instructions.
NOTICE: An access panel will simplify future maintenance.
Install the faucet valving according to the faucet manufacturer’s instructions. Do not install the
faucet trim until instructed. Open the hot and cold water supplies, and check the supply

7. Make Electrical Connections
NOTE: The whirlpool model number is printed on a label near the whirlpool pump. This label also
identifies the electrical rating of the whirlpool. All whirlpools come equipped with a wiring junction box
and will only operate at 220 V through 240 V and at 50 Hz or 60 Hz.
WARNING: Risk of electric shock. To reduce the risk of electric shock, connect the pump to a
properly grounded Ground-Fault Circuit-Interrupter (GFCI) or Earth-Leakage Circuit-Breaker (ELCB).
This will provide additional protection against line-to-ground shock hazard. A 220 - 240 V, 20 A, 50/60
Hz dedicated circuit is required.
WARNING: Risk of electric shock. Make sure the power has been disconnected before performing the
following procedures.
The whirlpool controls and system have been prewired at the factory. A licensed electrician should
make a routine service connection to the junction box.
Connect service to the junction box. The junction box contains blue, brown and green with a yellow
stripe colored wires and a ground lug.
Provide a separate equipment earthing conductor for the earth lug located inside the junction box.
The earthing conductor must not be connected to any current-carrying conductor. Follow local
electrical codes. Bond in accordance with national and local codes.
A wiring harness has been prewired at the factory, allowing communication between the keypad, all
features, and the control. No additional wiring is required, but ensure that all wires are securely
fastened.
NOTE: Your wiring harness includes an antenna for the optional remote control. Do not alter or damage
this antenna during installation.

8. Install the Whirlpool Trim Kit
Install the whirlpool trim kit according to the instructions packed with the trim kit. Pay particular
attention to the jet installation steps below - they are very important and are included here to help
you obtain smooth, trouble-free jet operation.
NOTE: The jet O-ring must be correctly positioned, must be lubricated, and must be in good condition to
permit easy rotation and proper operation of the jet.
Install the O-ring onto the first shoulder of the jet. Lubricate the O-ring with silicone lubricant to
prevent noisy operation of the jet.
Carefully insert the jet into the housing, and lightly push and rotate the jet until it snaps into
position. Do not force the jet.
NOTE: When installed correctly, the jet should turn smoothly both clockwise and counterclockwise.
9. Install the Neckjet Pillow (if Equipped)
The whirlpool is supplied with one pillow and two slip covers. The pillow includes a built-in
magnetic reed switch. The neckjets will not operate unless the pillow is installed. Always use a slip
cover to prevent water from spraying from the whirlpool.
Choose a slip cover, and fit it over the pillow.
Carefully slide the pillow down onto the neckjet body grooves until it is secure. The neckjets are
now ready for use.
We recommend periodic cleaning of the slip cover. Follow the cleaning instructions on the label
attached to the slip cover.
10. Test Run the Whirlpool
Check all electrical connections, and make sure the electrical power to the whirlpool is turned on.
Make sure all union connections to the pump and heater are securely hand tightened.
Verify that the pump banding straps have been cut, and that the pump control is resting directly on
the subfloor. Ensure that the rubber isolation feet are in place.
Fill the whirlpool until the water level sensors (if equipped) are submerged. If your whirlpool does
not have sensors, fill the whirlpool to a level at least 2″(5.1 cm) above the highest jet.
Operate the whirlpool for 5 minutes (refer to the ″Operating Sequence″section) and check all
whirlpool piping connections, on the back side, for leaks.
