Clear space for pump.
3. Secure the Unit
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.
Position a clean drop cloth or similar material in the bottom of the whirlpool. Be careful not to
scratch the surface of the product.
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.
The whirlpool should be shimmed no more than 1/2" (1.3 cm).
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.
Secure the whirlpool to the studding using the nailing-in flange and screws. Holes should be
pre-drilled from the acrylic side.
Fasten a plywood board under the pump to the subfloor using wood shims as necessary. Use
anchors if the subfloor is concrete. The board must be securely fastened to the floor.
