INSTALLING THE TEMP-GARD SHOWER VALVE

MAX OPERATING PRESSURE = 125 PSI.
1. Install rough piping and valve body as shown. Do not use
PEX or CPVC CTS piping from valve to tub spout, this causes
too much back pressure for valve to function properly.
• When facing valve, HOT "H" is on left and COLD "C"
is on right. Refer to marking on casting when installing.
(NOTE: When installing a valve with suffix "RC", the
inlets will be reversed.)
• Valve should be installed with the plastic finishing frame
lettering face flush with the finish wall. All other trim
should be set aside.
WARNING: Caution should be taken when heating valve for
sweat connections to avoid damaging internal rubber and
plastic components in valve.
FOR OPTIMUM VALVE PERFORMANCE, BALANCE SUPPLY
PRESSURES TO LESS THAN 5 PSI PRESSURE DIFFERENTIAL
BETWEEN HOT AND COLD WATER SUPPLIES.
2. While finishing tile wall, remove plastic finishing frame and
fill area around valve body with grout or plaster.
• Be careful to keep all ports free of obstructions.
3. Turn on both hot and cold supplies and flush out valve.
• Valve will not operate unless both hot and cold water are
turned on.
• Allow valve to run in warm position for a few minutes
to totally flush system. IF SYSTEM IS EXCESSIVELY
DIRTY, REMOVE THE CONTROL SPINDLE ASSEMBLY
TO ENSURE PROPER FLUSHING.
4. Set limit screw as directed by warning below.
5. Tighten packing nut(#10) to 15 in. lbs. of torque. Check for
desired frictional resistance when rotating handle(#38).
Packing nut (#10) can be tightened additionally, in small
increments, to increase frictional resistance.
• Check bonnet, packing nut, diverter spindle o-ring,
and all valve, pipe, and fitting connections for leaks.
6. Assemble external trim on valve
• Install escutcheon(#36)
(For valves without integral volume or integral volume/
diverter controls)
• Install cover(#31) and dial plate(#32) with (2) cover
screws(#35).
• Remove protective coating from dial plate.
• Install temperature control handle(#38).
(For valves with integral volume or integral volume/diverter
controls)
• Cover(#31) and dial(#32) are to be assembled by slid-
ing diverter/volume control lever handle(#33) into the
cover with the diverter clip(#34).
• Install the assembly with(2) cover screws(#35).
• Remove protective coating from dial plate.
• Install temperature control handle(#38).
NOTE: When there is a shutoff valve installed after the control
valve, there shall be stop and check valves on the inlets. This is
to eliminate hot and cold cross-connection in the event the
valve handle is left on. Specify suffix "-SC" for ASSE approved
checks.
