Installation Instructions for Valve
CAUTION: If optional cabinet is to be used, the cabinet must be mounted before the valve
is installed. Please refer to the cabinet mounting instructions on pages 4-5.
Note: Flush the supply lines before beginning
installation.
Note: When the check valves are in the open (operating)
position, the cover screw for the stop/check stem will be
flush with the valve cap (see Figure 1).
1. Connect the hot and cold valve supply inlets to the
appropriate hot and cold supply piping.
2. Connect the mixed valve supply outlet from the
valve to the tempered supply piping.
3. Screw the thermometer into the hole in the valve
body (see Figure 2). The thermometer provides a
readout of the outlet water temperature.
4. Pressurize the thermostatic mixing valve and check
for pipe leaks.
5. Slowly open the outlet valve to fill the piping system.
6. Check the temperature when approximately 20
GPM water flow is reached (equivalent to one drench
shower) and adjust if necessary [the range of the valve
is 65°F–95°F (18°C–35°C)]. To adjust the tempera-
ture, follow the procedure below:
• remove the slotted cover screw to expose the set screw
• using a 5/32" hex-head Allen key, turn the set screw
counterclockwise to increase the temperature or
clockwise to decrease the temperature.
Note: The standard preset factory temperature setting is
85°F (29°C). Consult proper medical and/or safety author-
ities for the optimum temperature recommended for your
particular application.
7. Shut the hot water inlet off by closing either the hot
water check valve or inlet valve. While the hot water supply is turned off, check to make sure the cold
water is flowing properly. If the cold water is flowing properly, reopen the hot water supply.
8. Shut the cold water inlet off by closing either the cold water check valve or inlet valve. While the cold
water supply is off, check to make sure that the hot water flow has shut down.
9. Test the system weekly (turn on the water supply and check for constant control of the desired set
temperature).
