Commissioning
The valve has been factory set under
balance pressures and hot water supply
at 65°C.
When your specific operating conditions
are significantly different from above, the
temperature of the water may vary from the
setting.
When the difference is too great, you can
adjust the calibration of the valve to suit
individual requirements of the installation:
1. Check the temperature of the water
being delivered from the outlet with a
thermometer, when the temperature control
handle is located at 6 o’clock.
Note:
temperature readings should be taken
at normal flow rate after allowing for the
system to stabilise.
2. If the temperature is not 38°C proceed to
reset the calibration as follows:
Remove the temperature control handle
(see fig.1)
Ensure the step on the stop ring is located at
4 o’clock
(see fig.2)
.
Do not remove the stop ring. Turn the spline
of the thermostatic valve clockwise to
decrease the temperature and anti-clockwise
to increase the temperature until 38°C is
achieved at outlet.
Note:
the sensing part of the thermometer
probe must be fully submerged in the water
that is to be tested.
Replace the temperature control handle
ensuring that the lever is located at 6 o’clock
(see fig.3)
.
With the handle attached ensure the
temperature does not exceed 42°C when
turned anti-clockwise to the fully hot
position
(see fig.4)
.
Your valve setting is now commissioned.
