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.
5.1 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.
5.2 Operating the appliance
The continuous-flow heater has two power settings:
"eco" Economy setting – two thirds power
"comfort" Intensive setting – full power
The "eco" setting is ideal for:
"comfort" setting should be used where a higher temperature or a larger
volume of water is required, e. g.
If you are using a thermostat-controlled mixer tap, set the heater to
"comfort" .
1. Set the heater to either "eco" or "comfort" , as required.
2. 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.
• Slightly close the hot-water tap. The water flows through the
appliance more slowly and reaches a higher temperature as a result.
Decreasing the water temperature
• Mix with cold water.
Note about operation
When a hot-water tap is turned on by only a small amount,
the continuous-flow heater operates at half power regardless of which
setting (
"eco", "comfort" ) has been selected.
When a hot-water tap is turned on fully, the appliance operates
at the maximum level of power that corresponds to whichever setting
has been selected.
Saving energy
• Please use economy setting “eco” as often as possible.
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 thermostat-controlled mixer taps.
The thermostat-controlled mixer tap must be suitable for hydraulically
controlled continuous-flow heater.
Winter operation
NOTICE:
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.
5.3 Cleaning
• Simply wipe the appliance with a damp cloth. Do not use acidic
or abrasive cleaning materials.
NOTICE:
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.
