3. How to use
• 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.
Cleaning and maintenance
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. 10seconds of continuous water
flow.
Venting after maintenance work
This instantaneous water heater was manufactured conscientiously and checked sev-
eral times before delivery. Should malfunctions nevertheless occur, it is usually only
due to a bagatelle. First attempt to switch the house fuses off and on again in order to
reset the electronics. Next, try to remedy the problem with reference to the following
table. In doing so, you will avoid unnecessary expense of customer service assistance.
Repairs must only be carried out by
authorised professionals.
If a fault in your appliance cannot be
rectified with the aid of this table, please
contact the service organisation of
your importer or the Central Customer
Service Department. Please have the
details of the typeplate at hand.
