 Installation Instructions
5)  Remove protective shield
If protective shield was attached 
in  Step 3 then remove shield 
snap tted over the end of valve 
spindle once valve is securely 
installed and wall nish work 
has been completed.
6)  Adjust valve packing nut
Reference gure 3 below
 ■ Turn hot & cold supplies on.
Valve will not operate unless 
both hot and cold water supply 
pressures are turned on. 
 ■ Place handle over end of control 
spindle stem.
 ■ Adjust packing nut for positive 
frictional resistance as handle 
is rotated from shuto position 
across adjustment range.
 Rough-in Installation
Control valve assembly, piping 
and fittings (Note: Illustrations below 
show valve model without stops)
Reference as required:  Page

1)  Determine wall thickness
 ■  
Determine type of wall and wall 
thickness where valve will be 
mounted.
 ■ Consider whether to use mounting 
plate by reviewing gure 2 below.
 ■ Skip ahead to Step 3 if mounting 
plate is not used.
2)  Attach valve mounting plate
Seat mounting plate against valve 
assembly as illustrated in gure 1.
3)  Attach protective shield
 ■ Reference gure 2 to determine 
whether shield is required.
 ■ Attach protective shield by snap 
tting over end of valve spindle.
4)  Install piping, fittings and 
control valve
Piping and ttings not supplied
 ■ Control Valve
Install through cutout hole in wall 
as specied in gure 2 below and 
dimension illustration on page 4. 
 ■ 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 
inlet marked H and cold water 
supply to valve inlet marked C.
 ■ Tub Spout (T on valve)
Pipe from outlet port on valve 
marked T to tub spout.
Important! Do not 
substitute Tub Spout with 
restrictive ttings such as
PEX, CPVC or outlet accessories such 
as a ledge spout, hose and spray that 
would subject the valve to excessive 
internal back pressure, otherwise  
operation will be compromised.
