The ON/OFF indicator illuminates when water is being heated.
4.1 Holiday and absence
f f If the appliance is not to be used for a few days, set the tem-
perature selector to a position between the frost protection
and energy saving settings.
f f If the appliance is not to be used for a longer period, set it to
frost protection to conserve energy. If there is no risk of frost
you may disconnect the appliance from the power supply.
f f For reasons of hygiene, heat up the content of the water
heater once to above 60 °C before initial use.
5. cleaning, care and maintenance
f f Have the electrical safety of the appliance and the function of
the safety valve regularly checked by a qualified contractor.
f f Have the protective anode initially checked by a qualified
contractor after the first year. The qualified contractor will
then determine the intervals at which it must be checked
thereafter.
f f Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
scaling
f f Almost every type of water will deposit lime at high temper-
atures. This settles inside the appliance and affects both the
performance and service life. The heating elements must
therefore be descaled from time to time. A qualified contrac-
tor who knows the local water quality will tell you when the
next service is due.
f f Check the taps/valves regularly. You can remove limescale
deposits at the spouts using commercially available descaling
agents.
f f Regularly activate the safety valve to prevent it from becom-
ing blocked e.g. by limescale deposits.
6. troubleshooting
Problem cause remedy
The water does not heat
up and the ON/OFF indi-
cator does not illuminate.
There is no power. Check the fuses/MCBs in
your fuse box.
The water does not heat
up sufficiently and the
ON/OFF indicator illumi-
nates.
The temperature is set
too low.
Select a higher temper-
ature.
The appliance heats,
for example, after large
amounts of DHW have
been drawn.
Wait until the ON/OFF
indicator goes out.
The flow rate is low. The aerator in the tap or
shower head is scaled up
or contaminated.
Clean and/or descale the
aerator or shower head.
If you cannot remedy the fault, notify your qualified contractor. To
