Wood Construction
NOTICE: Adequate floor support must be provided. Consult the roughing-in sheet packed with your
whirlpool for specific floor loading requirements.
CAUTION: Risk of product damage. Do not support the whirlpool by the rim.
Make sure the flooring offers adequate support for your whirlpool, and verify that the subfloor is
flat and level.
The whirlpool should be installed in an alcove installation. Construct 2x4 stud framing designed for
your particular installation in accordance with the roughing-in information packed with the
whirlpool.

4. Install the Whirlpool
WARNING: Risk of personal injury. This cast iron whirlpool is extremely heavy. Obtain sufficient help
to carefully lift and move it.
CAUTION: Risk of product damage. Do not lift the whirlpool by the piping or pump, or use the
piping or pump for structural support of the whirlpool.
CAUTION: Risk of product damage. Do not support the whirlpool by the rim.
Carefully move the whirlpool into position. Insert the drain tailpiece into the trap.
Level the whirlpool by fitting metal shims under the whirlpool feet as needed. Check for level along
the top of the whirlpool, and across the drain side. If the feet are not accessible from the back or
side, move the whirlpool in and out of position to shim it properly. Make sure the whirlpool is
resting on all four feet.
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
connections for leakage.
Run water into the whirlpool, and check the drain connections for leakage.
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. 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 to a level at least 2″(5.1 cm) above the top of 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.
For additional information on whirlpool operation, see ″Confirm Proper Operation″section.
Slide the O-Ring
onto the first
shoulder of the jet.
Inspect and
lubricate the
O-Ring.
Insert the jet into the housing,
and lightly push and rotate
until it snaps in position.

10. Complete the Finished Wall
If you have not already done so, carefully remove any protective tape from the whirlpool rim.
Cover the framing with water-resistant wall material. Seal the joints between the whirlpool rim edge
and the water-resistant wall material with silicone sealant.
Tape and mud the water-resistant wall material. Install the finished wall to the water-resistant wall
material so it is 1/16″(2 mm) above the enameled surface. Seal the joints between the whirlpool rim
and the finished wall material with silicone sealant.
Install the faucet trim according to the instructions packed with the trim.
11. Complete the Concrete Installation
If you have not already done so, carefully remove the protective tape from the whirlpool rim.
Apply mortar and tile to the wall, deck and surround material as needed.
Apply a bead of sealant where the tile meets the whirlpool surface.
Install the faucet trim according to the instructions packed with the trim.
12. Clean-Up After Installation
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. Do not allow cleaners
containing petroleum distillates to remain in contact with any whirlpool surfaces for long periods
of time. 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.
