5 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!
WARNING:
Risk of electric shock!
Switch off the mains voltage supply immediately if a fault occurs.
• Immediately shut off the cold water supply to the appliance should
it leak.
6 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 different locations.
It should be installed close to the tap that is used the most frequently.
This will enable you to reduce energy consumption.
7 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.
7.1 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.
7.2 Decreasing the water temperature
• Mix with cold water.
7.3 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.
7.4 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 required water temperature is
achieved.
8 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.
9 A fault, what to do?
WARNING:
Attention!
Repairs must only be carried out by an authorised technician. Improper
repairs can lead to risk of serious injury to the user.
If your appliance does not operate as required, it is often due to a very
minor problem. Please check whether you can remedy the fault yourself
by using the following guidelines. You will save yourself the costs of an
unnecessary visit by customer service personnel.
The water does not heat up or not enough water flows out of the tap:
• Check the fuse in the fusebox.
• Drop in pressure in the water mains. If the pressure is too low, the
appliance will not switch on.
• The strainer on the tap or shower head is blocked. Unscrew the
strainer and either clean or descale it.
• The corner valve is clogged. Turn on the hot-water tap fully and open
and close the corner valve several times. Then clean the filter in the
water tap.
• The heater needs descaling. Arrange for a service engineer to visit.
The continuous-flow heater switches off during the drawing-off of
water, resulting in a reduction in the water temperature:
• The washer inside the hot-water tap must be a non-swelling type.
If you cannot resolve the problem yourself, switch off the heater via the
fuse in the domestic wiring. Arrange for a service engineer to visit.
10 After-sales service
If you call the after-sales service for assistance, please specify the E no.
and FD no. of your appliance.
These numbers can be found on the underside of the continuous-flow
heater.
