Typical Installation Figure 1
When installed at or near the water heater and without a
recirculation system:
Install the valve as shown in Figure 1 with the mixing valve
positioned below the hot water tank or heater. If this is not
possible, pipe in a heat trap as shown.
Typical Installation Figure 2
When installed away from the water heater with a
recirculating pump on the hot water supply line:
Install the mixing valve as shown in Figure 2. The non-
circulated loop should be limited to 10 feet and must be
flushed periodically.
Notes:
If the valve is installed 20 feet or more from the water heater, it is
important to recirculate the hot water supply to the mixing valve.
The mixing valve must be installed with inlet check valves and the shower
or the Eyewash/Facewash fixture should be installed 4 to 10 feet from the
mixing valve. Hot and cold water inlet pressures must be equal.
Provisions shall be made to thermally isolate the valve.

temperatures. Provisions shall be made to thermally
isolate the valve. Cold water pipe installed in the
ceilings of boiler rooms or rooms that increase
ambient temperature require a recirculating pump.
