1. Prepare the Site

NOTICE: Unless otherwise speciﬁed, ﬂoor support under the whirlpool must provide for a minimum of

80 lbs/square foot (390 kg/square meter) loading.

NOTICE: 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 a drop-in, ﬂush, or tiled ledge installation. Construct 2x4 or 2x6

stud framing designed for your particular installation. Provide for a 1/16″(2 mm) gap between the

bottom of the whirlpool rim and the stud framing for drop-in installations. Frame the ﬂoor, or

construct a frame for a raised installation in accordance with the roughing-in information packed

with the whirlpool.

Carefully lay out and cut the rough deck material. Use the cut-out template if one is provided, or

refer to the roughing-in cut-out information.

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.

3. Secure the Unit — Models With Support Blocks

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.

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

appropriate instructions.

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

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.

Insert the drain tailpiece into the trap. Make sure 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.

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.

Position the rough

plumbing.

Frame the floor

according to the

roughing-in information.

Verify that the subfloor

offers adequate support,

and is flat and level.

Provide a 1/16" (2 mm) gap

between the whirlpool rim

and framing.

Construct 2x4 or 2x6

stud framing according

to the roughing-in

information.

4. Secure the Whirlpool to the Stud Framing

Option for Integral Flange Models

Drill a small pilot hole through the nailing-in ﬂange at each stud. Add shims between the nailing-in

ﬂange and the studs as needed to eliminate gaps.

Nail 1/4” (6 mm) thick furring strips to the studs to shim out to the edge of the nailing-in ﬂange.

Use #6 large-head galvanized nails to secure the nailing-in ﬂange to the studs.

For tile ledge installations, size and install a pressure-treated wood batten along the nailing-in

ﬂange. Pre-drill nail holes through the wood batten and nailing-in ﬂange before securing with

galvanized nails.

Nail 1/4" (6 mm) furring

strips to the studs.

6. Cut the Pump Banding Straps

NOTE: If your pump model does not have banding straps, proceed to the next section.

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

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.

Use tin snips to cut the two pump banding straps. When the banding straps are cut, the pump

support bracket and pump will drop about 1/2″(1.3 cm) until they rest on the subﬂoor. If the pump

drops more than 1/2″(1.3 cm), shim under the pump support bracket so there is a 1/2″(1.3 cm)

gap between the pump and bracket to allow for proper drainage.

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.

Secure the pump support bracket to the subﬂoor with screws or lag bolts (not provided).

7. 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.
