INSTALLATION OF TEMP-GARD III SHOWER VALVE (Refer to page 4 for part no.)
1. Install rough piping and valve body as shown.
Do not use PEX or CPVC CTS piping from
valve to tub spout, as the reduced ID re-
sults in too much back pressure for valve
to function properly. When facing valve, HOT
"H" is on left and COLD "C" is on right. Tub
port "T" should face down and shower port "S"
should face upward. The ears on the valve at
the 5 o'clock and 11 o'clock positions may be
used to attach the valve to framing of wall if
necessary.
WARNING: Caution should be taken
when heating valve for sweat connec-
tions 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. Always install valve with mud guard (23) so that the indicated surface on mud guard is flush with finished wall.
The hole in the wall should be 4" in diameter.
3. If valve is to be used for a shower only, wrap threads on tub plug (24) with teflon tape and install plug into tub
port on shower valve.
4. When the final outer wall is finished remove mud guard and open both supply stops on valve by turning counter
clockwise.
5. Loosen and remove escutcheon (19) from valve. Carefully remove cartridge (10) from valve by holding car
tridge as close to the valve body (1) as possible and wiggling back and forth until cartridge comes out of the
valve. Place thumb and finger on gray part of cartridge to remove it, as shown in Figure 4.
6. With the cartridges removed from all valves in the system, turn on water supply and flush the system of any
debris. If the water coming out of the valve while flushing is going behind finished wall, a hose bib flushing
out kit (RK7300-20HB) may be used to allow the water to be directed to a drain by attaching a garden hose
to valve.
7. If hot and cold supply inlets are reversed simply remove cartridge and reinstall with cartridge flipped
o
180 . The handle adaptor (12) will need to be readjusted. To adjust handle adaptor remove and turn
o
180 . Handle should always turn through cold, then hot. Reinstall cartridge and tighten escutcheon
to 150 in lbs. The system will need to be flushed again before installing shower heads.
