4. Secure the Unit — 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

base as needed.

With help, carefully lift the whirlpool into position.
