How to save energy
Set the exact temperature you need on the appliance
and open the hot water tap. Once you feel that the
water is too hot, do not add any cold water and,
instead, enter a lower temperature on the appliance.
If you were to add cold water, the water already
heated would cool down again and valuable energy
would be wasted. Moreover, the cold water added
in the tap is not covered by the control range of the
electronic circuitry, with the result that temperature
constancy is no longer guaranteed.
ECO mode
The symbol
shows that the appliance works in
an energy saving mode (i.e. the momentary energy
consumption is subject to the selected temperature
and to the flow rate in the energy saving mode.
Power limit
If the full output of the instantaneous water heater
does not suffice to heat the tapped quantity of water,
this will be indicated by
on the LCD (e.g. in winter
time, when opening several taps at once). When you
reduce the hot water flow rate,
stops lighting
because the output of the appliance is sufficient to
reach the set temperature again. You can now use the
full output to fill larger containers, for instance.
Operation with solar systems
When operating with solar systems, e.g. an automatic
mixing tap must ensure that the maximum inlet
temperature is not exceed. If the inlet temperature
exceeds the setpoint, the icon on the digital display
indicates that the heating power is switched off.

Venting after maintenance work
This instantaneous water heater features an automatic air bubble
protection to prevent it from inadvertently running dry. Nevertheless,
the appliance must be vented before using it for the first time. Each
time the appliance is emptied (e.g. after work on the plumbing system,
if there is a risk of frost or following repair work), the appliance must
be re-vented before it is used again.
1. Disconnect the instantaneous water heater from the mains (e.g.
via deactivating the fuses).
2. Unscrew the jet regulator on the outlet fitting and open the
cold water tap valve to rinse out the water pipe and avoid
contaminating the appliance or the jet regulator.
3. Open and close the hot water tap until no more air emerges from
the pipe and all air has been eliminated from the water heater.
4. Only then should you re-connect the power supply again (e.g.
via activating the fuses) to the instantaneous water heater and
screw the jet regulator back in.
5. The appliance activates the heater after approx. 10 seconds of
continuous water flow.
Cleaning and maintenance
• Plastic surfaces and fittings should only be wiped with a damp
cloth. Do not use abrasive or chlorine-based cleaning agents or
solvents.
• For a good water supply, the outlet fittings (special tap aerators
and shower heads) should be unscrewed and cleaned at
regular intervals. Every three years, the electrical and plumbing
components should be inspected by an authorised professional
in order to ensure proper functioning and operational safety at
all times.
