6. Temperature adjustment
Caution!!!
The water temperature in the instantaneous water heater depends on
the water flow rate. The higher flow rate, the lower temperature and the
other way round. Too high outlet water temperature may trigger thermal
protection causing device blockage. To unblock the device, you have to
press the thermal protection button.
1. Cut off the power supply of the heater.
2. Take off the case.
3. In order to increase the outlet water temperature, lower the water flow by turning the
control valve with a screwdriver towards ”+” or to lower the outlet water temperature
by turning the control valve towards “–“. (fig.7).
Use table 3 to reach an ideal water temperature..
