INSTALLATION:
Before connecting the tee and mixing valve to the water heater, it is important to consider the alignment required to enable
connection of the tee to the mixing valve withthe flexible hose or piping and the positioning of the mixing valve to allow easy
access for adjustment. If a recirculation return line is also being installed the position of the recirculation port also needs to
be considered.

MIXING VALVE TEMPERATURE ADJUSTMENT:
Prior to setting the valve it is necessary for the hot water source to be switched on and delivering hot water at the design
temperature.

INSTALLATION IN RECIRCULATED SYSTEMS:
The 5123-WH-N includes a recirculation port
to allow return water from the system to be
connected directly back into the mixing
valve. To use this recirculation port, remove
the plug using an Allen key (3/8").
1. Apply sealing tape to the hot and cold
connections on the water heater.
Connect the hot inlet of the mixing
valve to the hot outlet of the water
heater, ensuring that the adjustment
mechanism is easily accessible and
that the recirculationport is positioned
for easy connection to the system
return line.
3a. Insert the combination screen/gasket
into the nut side of the flexible hose
and connect the hose between the tee
and the mixing valve.
4. Connect system cold water inlet sup-
ply to the tee inlet and the system hot
water outlet supply to the mixing valve
outlet.
1. Using an accurate thermometer,
test the mixed water temperature
at the nearest outlet being sup-
plied by the valve. The test outlet
should not be a shower with its
own temperature limiting control
valve. This should be opened to
allow a minimum flow rate of 1.5
gpm (6 L/min). Allow the water to
run for at least one minute to
ensure the mixed water tempera-
ture has settled.
3. Using the wrench to support the-
locking nut and prevent it from
rotating, turn the Allen key to
adjust the outlet temperature -
clockwise
to
decrease
temperature, counterclockwise to
increase the temperature - until
the desired set point is reached.

of the water heater, ensuring that
its mixing valve connection is
aligned to allow connection to the
mixing valve via the flexible hose
or hard pipe.
3b. Connect the flexible hose/hard
pipe between the tee and the
mixing valve.
2. Holding the 3/16" Allen
key (supplied), loosen the

locking nut with a 7/16"
wrench.
4. Holding the Allen key, tight-
en the locking nut with the
wrench.
