4. Secure the Whirlpool to the Subfloor
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.
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 for Using a Cement or Mortar Bed
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 control
and support block locations.
NOTE: Do not use gypsum cement or drywall compound for this application, as they will not provide an
acceptable, durable bond.
NOTE: The pump control (when the pump banding straps are cut) and support blocks must rest
directly on the subfloor.
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 control 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 for 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.
Option for Using Silicone Sealant
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.
Apply a continuous bead of high-quality silicone sealant around the entire rim of the whirlpool.
