See type plate on the appliance.
3. Appliance description
The appliance constantly keeps the water content available at the
preselected 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 amounts of mixed outlet water.
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 through the safety
valve. This is a necessary and normal process.
3.1 Operation
You can set any required DHW outlet temperature variably at the
temperature selector. The heat-up indicator illuminates during
the heat-up process.

Cleaning, care and maintenance

f Never use abrasive or corrosive cleaning agents. A damp f
cloth is sufficient for cleaning the appliance.
f Check the taps regularly. Limescale deposits at the tap out- f
lets can be removed using commercially available descaling
agents.
f Have the function of the safety valve checked regularly by a f
qualified contractor.
f Have the protective anode checked by a qualified contractor f
after the first 2 years of operation. The qualified contractor
will then determine the intervals at which repeat checks
should be performed.
Almost every type of water will deposit limescale at high temper-
atures. This settles inside the appliance and affects both perfor-
mance 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.
