Thermostatic Valve
Installation Instructions
Tools Required:
- Flathead Screw Driver - Copper Tube Cutter
- Teflon Tape or Joint Compound
- Adjustable Wrench
- Channel-Lock Pliers
- Needle Nose Pliers
- Measuring Tape
- Safety Goggles
Packing List:
Note: The handles are designed to press on tightly to the stems of the
cartridges. You may apply a small amount of plumber’s putty to the
splines to help secure the handles onto the cartridge stems if necessary.
Thermostatic Valve Installation:
IMPORTANT: Do not turn the thermostatic cartridge stem too
far clockwise or counterclockwise (Fig. 1). Turning the
thermostatic cartridge stem past the internal stops will cause
it to malfunction and void the warranty.
1.
Flush all piping thoroughly to remove all dirt and
debris from inside the pipes.
2.
Shut off the main water supply to the installation
area.
3.
Make sure the mud plate is screwed snuggly to the
valve. Position the valve so the “HOT IN” water
supply is on the left and the “COLD IN” water supply
is on the right (Fig. 1). If you have a single handled
valve, the plug should be at the bottom or six
o’clock position.

4.
Make the proper measurements to determine the
depth at which to position the valve. The face of
the mud plate should be flush with the face of the
finished wall when completed (Fig. 2).
IMPORTANT: You must connect the hot water supply to the
left of the valve and the cold water supply to the right of the
valve. The valve will not function properly if the water
supplies are connected backwards.
5.
Connect the water supply pipes to the inlets. The
valve has 3/4” NPT pipe threads. You must use
Teflon tape or joint compound on all threaded
fittings. Use the appropriate connectors to attach
the pipes. If facing the valve, connect the hot water
to the left side of the valve and the cold water to
the right side of the valve (Fig. 1).
IMPORTANT: Do not solder at or near the main valve body.
The thermostatic cartridge and ceramic seats cannot
withstand heat from the torch. You must first solder the
fittings to the pipes and then screw into the valve. Then you
can continue to solder the pipes as long as they are several
inches away from the main valve body.
6.
Determine the position of the head shower outlet.
Make the appropriate measurements and connect
it to the top outlet of the valve.
7.
If you are connecting a hand shower or body
sprays, connect them to the bottom outlet of the
valve. Make the proper measurements to
determine the depth at which to position the
fittings. If you are not connecting these than check
to make sure the plug is tight.
CAUTION: READ THE FOLLOWING BEFORE
TURNING ON WATER SUPPLY
The thermostatic valve is designed to control the water
temperature between a range of 115°F and 70°F. This
temperature range is dependent upon external stops that
limit the movement of the thermostatic cartridge stem. One
stop is installed during manufacturing. The “Temperature
Stop Bracket” is located on the thermostatic cartridge (Fig
4). The other stop is located on the thermostatic control
knob and is called the “Stop Pin” (Fig. 5).
If the temperature control knob is not aligned properly
on the cartridge stem, the water temperature could reach
a level of scalding. Follow the directions for aligning the
temperature control knob closely to reduce the risk of
scalding. We advise setting your water heater output
temperature to 120°F.

8.
When all pipe connections are finished test the
system for leaks.
9.
Remove the mud plate and make sure the hot and
cold supply shutoffs are in the off position by turning
the stems clockwise until they stop (Fig. 1).
IMPORTANT: Do not turn the thermostatic cartridge stem too
far clockwise or counterclockwise. Turning the cartridge
stem past the internal stop will cause it to malfunction and
void the warranty.
Temperature Control Knob Installation:
10. Align the red mark on the thermostatic cartridge
stem with the red mark on the cartridge body. This
is the 105° calibrated temperature setting (Fig. 4).
11. Place the temperature control knob on the valve
with the stop pin at the top or 12 o’clock position
(Fig. 5). You may have to rotate it slightly in order to
align the splines of the knob with the splines of the
thermostatic cartridge stem to ensure a proper fit.
12. Turn the knob clockwise until it stops. The knob is
now in the cold or six o’clock position.
Water Check Prior to Final Assembly:
13. With the hot and cold shutoffs still in the off position,
slowly turn on the main water supply. Check for
leaks and repair if necessary.
14. Get buckets, if necessary, to catch the water from
the outlets (showerhead and hand shower/body
spray).
15. Connect the handles to the showerhead & hand
shower/body spray cartridges (Fig. 5). Turn on the
water to the two outlets one at a time and check
for proper hot and cold operation (Fig 3). Check
again for leaks and repair if necessary.
16. If all is well, turn the handles to the off position.
17. Remove the temperature control knob & handles
from their respective cartridges.
Installing Trim:
18. Apply a small bead of clear silicone to the outside
edge on the backside of the trim plate. Then apply
pressure to secure it to the wall over the valve
assembly, ensuring the holes align with the
cartridges (Fig. 6).

19. Place the supplied washers onto the handles (Fig.
6). Press the handles on the outlet cartridges making
sure the handles are positioned vertically while the
cartridges are in their off position.
Note: The handles are designed to press on tightly to the
stems of the cartridges. You may apply a small amount
of plumber’s putty to the splines to help secure the
handles onto the cartridge stems if necessary.
20. Now install the temperature control knob as before
with the appropriate washer (Fig. 7).
21. Align the red mark on the thermostatic cartridge
stem with the red mark on the cartridge body. This
is the 105° calibrated temperature setting (Fig. 4).
22. Place the temperature control knob on the valve
with the stop pin at the top or the 12 o’clock
position (Fig. 5). You may have to rotate slightly in
order to align the splines of the knob with the splines
of the thermostatic cartridge stem to ensure a
proper fit.
23. Turn the temperature control knob clockwise until it
stops. The knob is now in the cold or 6 o’clock
position.
24. If you have purchased a hand shower it can be
mounted where you desire. Hold the hand shower
mount base at the position you want it to be and
mark the holes (fig. 8).
25. Drill holes with a 7/32” drill bit and insert the plastic
inserts (fig. 8).
26. Screw the hand shower mounting base in place.
27. Put the hand shower mount over the base and
tighten the set screw (fig. 8).
28. Once you have finished the installation turn on the
water supply and allow the shower to run for three
minutes. Once again check for and repair any
leaks if necessary.
Removal/Maintenance of Thermostatic
Cartridge:
1.
Remove the handles, temperature control knob,
and trim plate.
2.
Shut off the water supply to the valve by tightening
the hot and cold supply shut off screws on the valve
(Fig. 9).

3.
Relieve the pressure in the valve by opening the
shower head cartridge (Fig. 9). The leftover water
pressure will come out of the shower head.
4.
Mark on the valve the position of the temperature
stop bracket. The bigger end should be on the left
side of the valve (Fig. 9).
5.
Use a ratchet and deep socket or other suitable
wrench to loosen the cartridge from the valve body
(Fig. 10).
6.
Pull the cartridge straight out of the valve (Fig. 10).
7.
Carefully rinse all dirt and debris from the screens on
the cartridge being careful not to damage the
screens or the o-rings.
8.
Once the cartridge is clean re-install it in the valve
body and tighten with a suitable wrench. Make sure
the temperature control stop is in the same position
as before. If it is not, try removing the cartridge and
re-installing it in a different position until it aligns
properly.
9.
Turn the water supply back on to the valve by
loosening the hot and cold supply shutoffs until they
stop.
10. Finally, re-install the trim plate and handles. See
“Installing Trim”.
