Installation of the Mixing Valve
1.
Flush all pipe work thoroughly before installing the mixing valve (using water only)
2.
The mixing valve comes complete with union type connections for ease of installation and
service.
3.
The mixing valve must be removed from the pipe work prior to soldering the end
connections. It is recommended to use a spacer piece while soldering.
Setting the Mixing Valve Outlet Temperature
1.
Remove the green knob by inserting a small screw
driver in the notch and gently prying up as shown in
Fig. 4-1.
2.
Setting of the mixing valve will be done after the tank
has been heated to its set point. To set the valve, it is
necessary to disconnect the outdoor sensor to the
control so the domestic hot water will reach its set
point temperature (default setting is 160°F). Once the
tank has reached its set point, turn both the hot water
and cold water supplies on. Open an outlet,
preferably a sink or basin rather than a
shower. To calibrate, let the water run for 2
minutes and measure the outlet
temperature with a thermometer. Using
the groove on the top of the cover
provided to fit over adjustment nut, adjust
the knob counter clockwise to increase
temperature and clockwise to decrease
temperature as shown in Fig. 4-2.
3.
Once the desired outlet temperature has
been achieved, refit the green top so that
it snaps onto the body of the mixing valve.
4.
Re-connect the outdoor sensor.
F. AUXILIARY PIPING
The auxiliary connections are additional connections provided to connect to an air handler, plate
exchanger or other devices that supply hot water. The auxiliary ports can also be used for recircula-

CAUTION
The mixing valve is certified to ASSE 1017. It is not to be used to provide anti-scald
service. Mixing valves are not designed to compensate for system pressure fluctuations
and should not be used where more sophisticated compensating temperature controls
are required.

DANGER
Do not solder unions while attached to the valve body. Solder connections prior to
connecting unions to the valve body to avoid damaging the valve and its function.
