ON/OFF indicator
The ON/OFF indicator illuminates when water is being heated.
4.1 Holiday and absence
 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.
 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.
 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
 Have the electrical safety of the appliance and the function of
the safety valve regularly checked by a qualified contractor.
 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.
 Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
Scaling
 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.
 Check the taps/valves regularly. You can remove limescale
deposits at the spouts using commercially available descaling
agents.
 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
facilitate and speed up your enquiry, please provide the numbers

Warranty
The warranty conditions of our German companies do not
apply to appliances acquired outside of Germany. In countries
where our subsidiaries sell our products, it is increasingly the
case that warranties can only be issued by those subsidiaries.
Such warranties are only granted if the subsidiary has issued
its own terms of warranty. No other warranty will be granted.
We shall not provide any warranty for appliances acquired in
countries where we have no subsidiary to sell our products.
This will not aect warranties issued by any importers.
Environment and recycling
We would ask you to help protect the environment. After use,
dispose of the various materials in accordance with national
regulations.
