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 results 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 connections to avoid dam-
aging 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
cartridge 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.
8. To adjust temperature limit stop (11), turn valve to desired hottest temperature, remove temperature
limit stop (11) turn clockwise and reinstall so that the white protrusion on cartridge is touching the red
protrusion on the temperature limit stop.
9. After all flushing is done install shower heads and check system for leaks.
