Due to individual site variations, exact
guidelines for every situation cannot be
supplied. The recommended framing and
dimensional requirements shown are
for a typical application and may vary,
depending on site requirements.
The dimensions shown in Figure 1a and
1b are from the surfaces where the unit
will be attached. This surface can be
bare studding, dry wall or other suitable
underlayment material.
IT IS IMPORTANT THAT THE FLOOR
AND ALL FRAMING BE SQUARE
AND LEVEL . Framing should be done
using accepted materials and construction
techniques, in accordance with all
applicable codes.
Installation Procedure
With the unit positioned in the alcove,
several details must be checked prior to
securing the unit in place (Figure 2a, 2b
and Figure 2c);
ü
Confirm dam is resting flush on the floor.
ü
Confirm drain alignment.
ü
Confirm the top of unit is level on all sides.
ü
Confirm the unit is square in the alcove
framework.
ü
Confirm the front inside corner is plumb
at each end. (This is critical for the
proper installation of an enclosure)
The unit must 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 leveled and square
in the alcove, drill a 1/8 inch hole through the
fastening flange at each framing member.
THE BOTTOM OF ALL HOLES IN THE
FLANGE HAVE TO BE AT LEAST 8MM (0.3
INCHES) ABOVE THE BASE THRESHOLD!
Secure the unit in place across the back
wall first, followed by the flanges at each
end, using 1-1/4 inch long screws or other
appropriate fasteners. Continuously check
to confirm the base remains square within
the alcove as it is being secured. (Figure
3a and 3b)
NOTE: IF UNIT IS EQUIPPED WITH
LEVELING LEGS PUT SHIMS UNDER
THEM IN ORDER TO LEVEL THE
BASE
