Operating the appliance
4 Operating the appliance
4.1 Switching the appliance on and off
The continuous-flow heater switches on and heats the water when the
warm water tap is opened. It switches off again if the water tap is closed.
4.2 Setting the water temperature
• Turn the rotary selector switch.
Use the continuously-variable switch to set the desired temperature for.
Note: If a thermostatic-regulating mixer tap is used for high
temperatures or for large water volumes, then it is recommended
that the setting "50 °C" or "60 °C" be selected.
4.3 Solar heated
The appliance can be operated with pre-warmed water (for example,
from a solar energy unit).
WARNING:
Attention!
Scalding danger!
▶ If the output temperature of the water leaving the tap is higher
than the set temperature, then this is because the supply water
temperature from the domestic system is too hot, e. g. due to its
being heated by a solar energy unit.
Increasing the water temperature
If a higher temperature is not obtained when the warm water tap is fully
opened, then this is because more water is flowing than the continuous-
flow heater's power capacity can heat.
• If this happens, then slightly close the warm water tap.
Decreasing the water temperature
• Turn the rotary selector switch to a lower level e. g. "30 °C".
Note: If the temperature of the water supplying the appliance changes,
then the output temperature of the water leaving the tap also changes
correspondingly.
4.4 Status display

Lights green On
Flashes green (1/s) The set temperature is not obtained; the rate
of water flow is too high for appliance rating

Flashes red See "A fault, what to do?"
4.5 Startup after power failure
• Open the warm water tap fully and allow water to flow until it is warm.
4.6 Using the appliance after switching off the water
supply
• Switch off the appliance (unscrew the fuse in the fusebox).
• Open the warm water tap and keep it open until the air has been
completely forced out of the water pipe.
6
• Switch the fuse back on again.
• Open the warm water tap fully and allow water to flow for at least
one minute.
Only then (for safety reasons) will the appliance begin to heat.
The appliance is now ready to operate.
4.7 Saving energy
• Set the desired water temperature directly on the appliance.
The appliance is operated economically when set to approximately
"40 °C".
Note: Mixing in of cold water at the faucet/fitting consumes unnecessary
water and energy.
This also accelerates calcification (scaling) of the appliance. Therefore,
please always set the desired temperature directly on the continuous-
flow heater.
4.8 Winter operation
Note: It is possible in winter that the supply temperature of the water
is reduced and the required outlet temperature is no longer achieved.
• Reduce the water flow on the taps until the desired water
temperature is reached.
5 Cleaning
• Only wipe off the appliance using a moist cloth.
• Do not use acidic or abrasive cleaning materials.
• Do not use a steam cleaner.
