Once you have set the required domestic hot water
temperature, you can lock the adjustment knob of the
mixer valve to prevent further tampering.
To do so, unscrew the fixing screw from the top of the
knob and pull off the knob. Fit the knob again so that
the keyway in the knob's body engages with the key in
the valve cap.
SETTING DOMESTIC HOT WATER TEMPERATURE
Domestic hot water temperature is preset to 44°C in the
factory.
Adjust the thermostatic mixer valve to change this value.
The following table shows the hot water temperature
values for the different mixer valve knob positions.
