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.

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.
Clear space for pump.
Spread a 2" (5.1 cm) layer of
cement or mortar bed material.
Clear spaces for
support blocks.
Apply a bead of silicone
sealant around the entire rim.
