The unit must also be positioned square in
the alcove framework. The use of shim or
filler material behind the fastening flange
at each framing member may be required
to maintain the unit in the proper position.
After the unit is confirmed level and
square in the alcove, drill a 1/8 inch
hole through the fastening flange at each
framing member and every 8 inches along
the front fastening flanges. Secure the
unit in place across the back wall first,
followed by the flanges at each end and
along the front flanges, using 1-1/4 inch
screws or other appropriate fasteners.
Continuously check to confirm the unit
remains square within the alcove as it is
being secured. (Figures 3a & 3b)
WARNING!
THE UNIT BOTTOM SHOULD BE
CLEAR OF ALL POTENTIALLY
DAMAGING DEBRIS AND THE
SURFACE PROTECTED BEFORE
STEPPING INSIDE.
CAUTION: It is advisable to protect
the unit surface with a thin plywood or
cardboard shield while fastening the
flange to the framing.
Water Supply and Drain Connections
Refer to, and follow, the assembly and
installation instructions provided with the
supply valves and drain system. Carefully
check all fittings and connections for
leaks.
Finishing Guidelines
Furring strips or filler material may be
required over the framing to ensure the
underlayment will lie flush over the fastening
flanges. A water resistant underlayment is
recommended on areas surrounding the
unit. Stop the underlayment 1/16 to 1/8 inch
from the unit surface, and fill the space with
a continuous bead of waterproof sealant.
Carefully fasten the underlayment near
the unit to avoid damaging the unit
surface. Seal the seams and edges of the
underlayment, as required, and install the
finish material to specifications. (Figure 4)
