Operating instructions
Please read and observe the detailed safety instructions
at the start of these instructions!
Important: The appliance may never be exposed to frost!
Risk of electric shock!
Switch off the mains voltage supply immediately if
a fault occurs.
Immediately shut off the cold water supply to the appli-
ance should it leak.

Getting to know your appliance

The continuous-flow heater heats the water as it flows
through the appliance. The appliance only consumes power
during this period.
This appliance can supply hot water to taps in several dif-
ferent locations. It should be installed close to the tap that
is used the most frequently. This will enable you to reduce
energy consumption.

Operating the appliance

Turn on the hot-water tap.
The continuous-flow heater switches on automatically and
heats the water as it flows through the appliance.
The heater switches off again when you turn off the tap.
Increasing the water temperature
When the tap is turned on fully, it is possible that the heater
capacity is not sufficient to heat the water to the required
temperature.
Turn the tap off slightly. The water flows through the
appliance more slowly and reaches a higher temperature
as a result.

Decreasing the water temperature
Mix with cold water.
Saving energy
To minimise energy consumption when turning off the hot
water:
– Turn off the hot-water tap slowly in order to use the
residual heat of the continuous-flow heater.
– This also prevents the water temperature from briefly
increasing above the preselected temperature if the hot-
water tap is turned on again within the next few minutes.
To obtain particularly uniform hot-water temperatures, it is
recommended to use thermostatically-controlled premixers.
The thermostatically-controlled premixer must be suitable
for hydraulically controlled continuous-flow heater.
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.
In order to compensate for this temperature reduction,
please reduce the water quantity on the tap until the re-
quired water temperature is achieved.
Cleaning
Simply wipe the appliance with a damp cloth.
Do not use acidic or abrasive cleaning materials.
Notes: It is normally not necessary to descale the appliance.
However, extremely hard water and the frequent flows of
very hot water can cause the appliance to scale up. In this
case please contact our after-sales service.
