Appliance description

WARNING Injury
!
The appliance may be used by children aged 3 and older
and persons with reduced physical, sensory or mental
capabilities or a lack of experience and know-how, pro-
vided that they are supervised or they have been in-
structed on how to use the appliance safely and have
understood the resulting risks. Children aged 3 to 8 years
may only operate the tap connected to the appliance.
Children must never play with the appliance. Children
must never clean the appliance or perform user main-
tenance unless they are supervised.
Where children or persons with limited physical, sensory or men-
tal abilities are allowed to use this appliance, we recommend a
permanent temperature limit. A qualified contractor can set this
limit.

If the drain pipe of the safety valve is sealed, the expan-
sion water may cause water damage.

See type plate on the appliance.
3. Appliance description
The sealed unvented (pressurised) appliance constantly maintains
the water content at the pre-selected temperature. The appliance
switches on automatically as soon as its temperature falls below
the set value.
Subject to season, varying cold water temperatures can result in
different maximum mixed water and outlet volumes.
Note
A qualified contractor can set a temperature limit on the
appliance (see "Installation / Settings / Setting the tem-
perature limit").
Note
The appliance is under mains water pressure. The water
volume increases as the cylinder is being heated up. Dur-
ing this process, expansion water drips out through the
safety valve. This is a necessary and normal process.
3.1 Operation
You can set any required DHW outlet temperature at the tem-
perature selector. The heat-up indicator illuminates during the
heat-up process.

Depending on the system, the actual temperatures may vary from
the set value.

Cleaning, care and maintenance

f Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
f Check the taps regularly. Limescale deposits at the tap out-
lets can be removed using commercially available descaling
agents.
f Have the function of the safety assembly checked regularly by
a qualified contractor.
Almost every type of water will deposit limescale at high temper-
atures. This settles inside the appliance and affects both the per-
formance and service life. The heating elements should therefore
be descaled if necessary. A qualified contractor who is aware of
the local water quality will tell you when the next descaling is due.
