flat and level.
For Whirlpools without Apron:
NOTICE: The whirlpool should be installed in a drop-in installation.
Construct 2x4 or 2x6 stud framing for your installation.
NOTICE: When planning the construction of the site, take into consideration that the whirlpool must be
supported by its feet or base to avoid product damage. 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. This includes whirlpools placed in alcove installations.
For a raised installation: Frame the floor or construct a frame 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.
For Whirlpools with Integral or Optional Apron:

chosen. Construct 2x4 or 2x6 stud framing designed for your particular installation. Construct a
frame in accordance with the roughing-in information packed with the whirlpool.
For All Installations:
Position the plumbing according to the roughing-in information packed. Cap the supplies, and
check for leaks.

2. Prepare the Whirlpool

3. Secure the Whirlpool — Models With Support Blocks
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.
Insert the drain tailpiece into the trap. Make sure 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. Make sure the whirlpool is level and resting on all support
blocks.
Clear space for pump.

4. Secure the Whirlpool — Models With Whirlpool Base
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.
Choose the installation option that best applies to your particular installation. Follow the appropriate
instructions.
If the subfloor is not level, shim the whirlpool base 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.
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.
Position a piece of plastic drop cloth material on top of the cement or mortar bed. With help,
carefully lift the whirlpool into place.
Insert the drain tailpiece into the trap. Make sure the whirlpool is level. Use screws or lag bolts (not
provided) to secure the whirlpool base to the floor. Drill small pilot holes through the whirlpool
base as needed.

5. Secure the Whirlpool to the Stud Framing
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.
6. Cut the Pump Banding Straps
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. 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.
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.
