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

your particular installation. Provide for a 1/16” (2mm) gap between the bottom of the whirlpool rim and

the stud framing. 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” (5cm) 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.

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.

5. Cut the Pump Banding Straps — Models With Support Blocks

NOTE: For models with a whirlpool base, 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” (1.3cm) until they rest on the subﬂoor. If the pump drops more

than 1/2” (1.3cm), shim under the pump support bracket so there is a 1/2” (1.3cm) 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).

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.

Kohler Co. 9 1010564-2-B

7. Install a Rim-Mounted Faucet

Measure and cut a piece of 1/2″exterior grade plywood 4″(10.2cm) x 11-1/2″(29.2cm) for the K-1226, or

4″(10.2cm) x 15-1/2″(39.4cm) for the K-1231.

The faucet should be located in the center of the ﬂat area of the rim. Refer to the faucet manufacturer’s

instructions. Use a pencil to mark the faucet centerlines for drilling.

NOTE: The K-1226 will accept faucets with 4″centers, and the K-1231 will accept faucets with 4″or 6″

centers.

CAUTION: Risk of product damage. Position a thin piece of cardboard on the ﬁnished surface of the

whirlpool before clamping the plywood in place. Make sure the clamps do not make direct contact

with the ﬁnished surface of the whirlpool.

Set a thin piece of cardboard on the ﬁnished surface of the whirlpool rim. Position the plywood on the

bottom of the rim, and carefully clamp the plywood in place. Make sure the clamps are in contact with the

cardboard, not the ﬁnished surface of the whirlpool.

Carefully drill the faucet holes to the size required by the faucet manufacturer. Remove the clamps and

cardboard.

Install the faucet to the rim and plywood according to the faucet manufacturer’s instructions.

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.

Measure, cut, and drill a piece o

1/2” exterior grade plywood 4”

(10.2cm) x 11-1/2” (29.2cm) for

the K-1226, or 4” (10.2cm) x
