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.
D
Operating elements
The continuous-flow heater has two heat settings:
Economy setting – two thirds power
Intensive setting – full power
The setting is ideal for:
– Wash basin
– Shower
– Bidet
The setting is used in combination with a thermostat
battery, for high temperatures or for large volumes of water,
e. g. for:
– Dishwashing
– Cleaning
– Bath tub
Operating the appliance
E
Turn on the hot-water tap
The continuous-flow heater switches on and heats the water
when the hot-water tap is turned on (Fig. E, 1.).
It switches off again when the tap is turned off.
Notes: When the water tap is turned on only slightly, the con-
tinuous-flow heater will operate at half power in both of the
preselected settings (
, ). When the water tap is turned
on fully, the appliance will operate at full, preselected power.
E Increasing the water temperature
Slightly close the hot-water tap (Fig. E, 2.).
E Decreasing the water temperature
Turn on the cold-water tap (Fig. E, 3.).
Startup after a water cutoff
■ Disconnect the appliance from the mains supply
(remove the fuses in the fusebox).
■ Turn on the hot-water tap until the air is purged from the
pipe.
■ Reinstall the fuses.
The appliance is ready for operation.
Saving energy
Use the setting whenever possible.
For wash basins: Open the corner valve to such an extent
that only the lower heat setting switches on.
Winter operation
Notes: 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.
After-sales service
If you call the after-sales service for assistance, please specify
the E no. and FD no. of your appliance.
