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 the 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 38°C is aligned with the stop
mark
(see fig 1)
.
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 commissioning as
follows.
Remove the handle. Pull off the screw cap on the underside
of the temperature handle. Using the supplied hexagonal key
release the grub screw within the handle.
Pull out the handle.
Ensure the step on the stop ring is the correct position
(see fig 2)
.
Do not remove the plastic 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 handle making sure that the ball in the handle is
against the step.
Once the handle has been attached ensure the temperature
does not exceed 46°C when turned entirely anti-clockwise.
Your valve setting is now commissioned.
