INSTALLATION AND FRAMING INSTRUCTIONS
Locate studs as required. Ensure roughing-in dimensions are proper, plumb and square. Access to Pump/Motor may be
made through the access opening in the apron panel. It is strongly recommended that an additional opening be provided for
access to the drain components.
NOTE: The apron may be used as the primary access opening.
1. As shown in Fig. 1, mark the position of the underside of the deck by tracing a line onto the studs, using a level or other
suitable straight edge.
2. With the top of the stringer touching the traced line, attach the stringer to the studs.
3. Install drain components to the whirlpool or bath following the manufacturers instructions. See the roughing-in drawing for
suggested opening size and location dimensions.
4. THIS BATH MUST BE SUPPORTED ALONG ITS ENTIRE BOTTOM. We recommend the use of mortar as bedding
material (sand is not recommended). Apply enough bedding to support the complete bottom of the bath. After the bedding
has been poured, and before it sets, position whirlpool or bath within recess until the rim is leveled against the leveling
stringers (see "Typical Recess Installation") shown below. The rim of the bath MUST NOT support weight. Allow the
bedding material to completely harden before applying weight to the rim or bottom of the bath. Any finish material such as
tile or wall board must be self-supporting if it contacts the deck of the bath.
