4. Secure the Unit
CAUTION: Risk of product damage. Do not lift the bath with airjets by the air channels or blower
motor, or use the air channels or blower motor for structural support of the bath.
CAUTION: Risk of product damage. Do not support the bath by the rim.
Choose the installation option that best applies to your particular installation. Follow the
appropriate instructions.
If the subfloor is not level, shim the bath support blocks 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 cm) thick layer of cement or mortar on the subfloor where the bath will be set. This
will help secure, level, and support the unit. Clear all the material away from the support block
locations.
Position a piece of plastic drop cloth material on top of the cement or mortar bed.
With help, carefully lift the bath into place, and make sure the support blocks do not rest in the bed
material.
Insert the drain tailpiece into the trap. Make sure the bath 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 bath.
Allow the sealant to cure according to the manufacturer's instructions.
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 bath into position.
Insert the drain tailpiece into the trap. Make sure the bath 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 bath.
Allow the sealant to cure according to the manufacturer's instructions.
