Commissioning
Note: mix water temperature at terminal fitting should never exceed 46° C.
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 the stop arm is located at 12 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 stop arm
(see Fig. 1)
.
Ensure the step on the stop ring is located at 12 o'clock
(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 stop arm making sure that the arm is against the step
(see Fig. 3)
When the handle is attached (see page 17) ensure the temperature does not exceed
46°C when turned entirely anti-clockwise.
Your valve setting is now commissioned.
