perature can be limited to approx. 55 °C by a specialist. You
can also obtain cold water from the mixer tap at any time.
The appliance can be used to supply one (open circuit opera-

I Recommended setting for optimum energy saving (≈ 35 °C)
e Setting for the average hot-water requirement, e. g. for
washing dishes (at ≈ 55 °C)
III Setting for hot water and greater warm water require-
ment, e. g. for cleaning (≈ 75 °C)
The specified temperatures are average values. They may
vary according to local conditions.
Note: Most efficient operation results with the recom-
mended setting I (≈ 35 °C). In setting e there is no longer
any growth of legionnaire's disease bacteria. Legionnaire's
disease bacteria are killed in setting III.
Cleaning
Simply wipe the appliance and mixer tap with a damp
■
cloth.
Do not use acidic or abrasive cleaning materials.
Maintenance for the customer
If required, unscrew the shower head or outlet pipe and
■
descale with a commercially available descaler or house-
hold vinegar.
Only pressure-resistant operation: The safety valve must
■
be operated regularly to verify its function and to descale
the valve.
When the water flows out of the hot water tap much
■
more slowly with the tap fully open, this is an indication
that the appliance requires dechalking. Call a specialist
immediately otherwise the water heater could be sub-
jected to high pressures.
Decalcifying, internal cleaning and repairs to the
appliance may only be performed by one of our
authorised customer service representatives.
