3. How To Use
USER
Each of the four user profiles can be provided with their own profile image. This image
appears in the main screen.
In the main screen, every user can set up and save his own desired temperatures for
the different applications.
INFO / DEVICE INFORMATION
The current status and appliance data are listed here. Use the sensor keys to scroll
through the different information values.
Top-Up Heating
When operating with preheated water (e.g. with solar systems), you must ensure that
the inlet temperature does not exceed 70 °C.
If the inlet temperature exceeds the setpoint, the appliance is not providing any out-
put. The symbol is displayed in the main screen
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 cir-
cuitry, with the result that temperature constancy is no longer guaranteed.
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 (e.g. jet regulators and shower heads)
should be unscrewed and cleaned at regular intervals. Every three years, the electri-
cal and plumbing components should be inspected by an authorised professional in
order to ensure proper functioning and operational safety at all times.
3. How To Use
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.
