Product Information

Electrical Requirements

The installation must have a Class A Ground-Fault Circuit-Interrupter (GFCI) or Residual Current Device (RCD). The GFCI or RCD protects against line-to-ground shock hazard. Use a 120 V, 15 A, 60 Hz dedicated service for the whirlpool.

″H″ models require a separate 120 V, 15 A, 60 Hz dedicated circuit for the in-line heater.

NOTE: If the pump supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualiﬁed persons in order to avoid a hazard. The heater supply cord cannot be replaced. If the cord is damaged the heater should be replaced.

according to the roughing-in information.

Verify that the subfloor offers adequate support, and is flat and level.

1. Prepare the Site

NOTICE: Refer to the Roughing-in Guide packed with your whirlpool for the required minimum lb/square foot (kg/square meter) ﬂoor support loading.

Make sure the ﬂooring offers adequate support for your whirlpool, and verify that the subﬂoor is ﬂat and level.

NOTICE: The whirlpool should be installed in a drop-in installation.

Construct 2x4 or 2x6 stud framing for your installation.

NOTICE: The whirlpool must be supported by its feet or base. Do not support the load weight of the whirlpool by the perimeter of the rim.

For a raised installation: Frame the ﬂoor or construct a frame in accordance with the roughing-in information packed with the whirlpool.

Position the plumbing according to the roughing-in information packed. Cap the supplies, and check for leaks.

2. Prepare the Whirlpool

Install the drain to the whirlpool according to the drain manufacturer’s instructions. Do not connect the trap at this time.

Position a clean drop cloth or similar material in the bottom of the whirlpool. Be careful not to scratch the surface of the whirlpool.

1010997-2-F 4 Kohler Co.

Spread a 2" (5.1 cm) layer of cement or mortar bed material.

Apply a bead of silicone sealant around the entire rim.

Clear space for pump.

Clear spaces for support blocks.

Apply construction adhesive to the support blocks.

3. Secure the Unit

NOTICE: Do not lift the whirlpool by the piping or pump, or use the piping or pump for structural support of the whirlpool. To avoid damage to the whirlpool, lift at the sides of the whirlpool.

NOTICE: Do not support the load weight of the whirlpool by the perimeter of the rim. The rim perimeter must be adequately supported, but must not support the load weight of the whirlpool.

If the subﬂoor is not level, shim the whirlpool support blocks as necessary.

Choose the installation option that best applies to your particular installation. Follow the appropriate instructions.

Option Using a Cement or Mortar Bed

NOTE: Do not use gypsum cement or drywall compound for this application, as they will not provide an acceptable, durable bond.

NOTE: The pump support bracket (when the pump banding straps are cut) and support blocks must rest directly on the subﬂoor.

Spread a 2″ (5.1 cm) thick layer of cement or mortar on the subﬂoor where the whirlpool will be set. This will help secure, level, and support the unit. Clear all the material away from the pump support bracket and support block locations.

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 support bracket and support blocks do not rest in the bed material.

Secure the drain tailpiece to the trap. Ensure the whirlpool is level and resting on all support blocks.

Option Using Construction Adhesive

Apply a generous amount of high-quality construction adhesive to the bottom of the support blocks. With help, carefully lift the whirlpool into position.

Insert the drain tailpiece into the trap. Ensure the whirlpool is level and resting on all support blocks.

Option Using Silicone Sealant

With help, carefully lift the whirlpool into position. Insert the drain tailpiece into the trap. Ensure the whirlpool is level and resting on all support

blocks. Remove the protective tape from the rim. Apply a continuous bead of high-quality silicone sealant

around the entire rim of the whirlpool.

4. 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. 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. Remove and discard the straps.

5. Install the Plumbing

CAUTION: Risk of property damage. A watertight seal must exist on the whirlpool drain. The watertight seal will prevent property damage.

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. Test Run the Whirlpool

Check all electrical connections, and make sure the electrical power to the whirlpool and heater (if equipped) is on.

Make sure all union connections to the pump and heater are securely hand tightened. Verify that the pump banding straps have been cut (if applicable), and that the pump is resting

directly on the subﬂoor or whirlpool base. Fill the whirlpool to a level at least 2″ (5.1 cm) above the top of the highest jet. Refer to ″Conﬁrm

edge and the water-resistant deck material with silicone sealant. Tape and mud the water-resistant deck material. Install the ﬁnished deck to the water-resistant deck

material. Seal the joints between the whirlpool rim and the ﬁnished deck material with silicone sealant.

Install the faucet trim according to the trim manufacturer’s instructions.

9. Clean-Up After Installation

When cleaning up after installation, do not use abrasive cleansers, as they may scratch and dull the whirlpool surface. Use warm water and a liquid detergent to clean the surface.

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.
