2. safety
2.1 intended use
This pressure appliance is designed to heat DHW.
This appliance is designed for domestic use. It can be used safely
by untrained persons. The appliance can also be used in a non-do-
mestic environment, e.g. in a small business, as long as it is used
in the same way.
Any other use beyond that described shall be deemed inappropri-
ate. Observation of these instructions and of instructions for any
accessories used is also part of the correct use of this appliance.
Any modifications or conversions to the appliance void all war-
ranty rights.
2.2 general safety instructions
WARNING Burns
There is a risk of scalding at outlet temperatures in ex-
cess of 43 °C.
!
WARNING Injury
The appliance can be used by children aged 8 and above,
as well as by persons with limited physical, sensory or
mental abilities, or with a lack of experience and knowl-
edge, provided they are supervised or have been in-
structed in the safe use of the appliance and understand
the resulting dangers. Children must not play with the
appliance. Cleaning and user maintenance may not be
carried out by unsupervised children.
Note
The appliance is under pressure.
During the heat-up process, expansion water will drip
from the safety valve. If water continues to drip when
heating is completed, please inform your heating con-
tractor.
2.3 ce designation
The CE designation shows that the appliance meets all essential
requirements according to the:
- Electromagnetic Compatibility Directive
- Low Voltage Directive
2.4 test symbols
See type plate on the appliance.
3. appliance description
The appliance electrically heats domestic hot water, with the tem-
perature controlled via the temperature selector. Subject to the
power supply and operating mode, the water is heated automat-
ically to the required temperature. You can use the appliance to
supply one or several draw-off points.
The steel cylinder is coated on the inside with special directly ap-
plied enamel and is equipped with a thermometer and a protective
anode. The anode with consumption indicator protects the cylin-
der interior from corrosion. The cylinder is enclosed by thermal
insulation and a casing.
The appliance is also protected against frost on the temperature
setting "cold" as long as the power supply is guaranteed. The ap-
pliance switches on in good time and heats the water. The water
supply line and the safety assembly are not protected against frost
by the appliance.
single circuit operation
The appliance automatically heats up at any temperature setting
subject to the availability of power.
dual circuit operation
During off-peak tariff periods (cheap rate periods of power supply
utilities), the appliance automatically heats up the water content
with standard heating output at any temperature settings. In ad-
dition, you can switch on rapid heating during peak tariff periods.

dual circuit operation with rapid heat-up function
You can switch on rapid heating with the pushbutton whenever
necessary. Rapid heating stops and will not restart once the se-
lected temperature has been reached.

5. cleaning, care and maintenance
f
f
Have the electrical safety of the appliance and the func-
tion of the safety assembly regularly checked by a heating
contractor.
f
f
Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
signal anode with consumption indicator
!
Material damage
If the consumption indicator changes colour from white
to red, have the signal anode checked by a heating con-
tractor and if necessary replaced.

scaling
Almost every type of water deposits lime at high temperatures.
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 contractor 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 tap outlets using commercially available des-
caling agents.
f
f
Regularly activate the safety valve to prevent it from becom-
ing blocked e.g. by limescale deposits.
6. troubleshooting
Fault
cause
Remedy
The water does not heat
up.
There is no power.
Check the fuses/MCBs in
your fuse box.
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 heating contractor. To
facilitate and speed up your enquiry, please provide the serial
number from the type plate (no. 000000-0000-000000):
Nr.: 000000 - 0000 - 000000
