1)
Determine wall thickness
Determine type of wall and wall
thickness where valve will be
mounted as follows:
Fiberglass or acrylic walls:
Thickness =
1/2” (13 mm)
or less
Dry wall, plaster, or other type
walls:
Thickness = more than
1/2"
(13mm)
Skip ahead to step 3
2)
Attach mounting plate
Seat plate against valve assembly.
3) Attach protective shield
Attach plastic protective shield
by snap fitting over end of valve
spindle as shown in Figure 2.
4)
Install control valve
Install through cutout hole in wall
as specified in Figure 2 below and
Dimensions illustration on page 4.
5)
Install piping and fittings
Piping and fittings not supplied.
Showerhead (S on valve)
Pipe from outlet port on valve
marked
S
to showerhead
mounting arm location.
Hot & Cold Supply (H & C)
Pipe hot water supply to valve
input marked
H
and cold water
supply to valve input marked
C
.
6)
Remove protective shield
Remove shield snap fitted over
the end of valve spindle after
valve is securely installed.
