3. Commissioning
Before commissioning, check whether the water
supply is open and the storage tank is full. Initial
filling and commissioning must be carried out by a
certified specialist company!
The entire system, including parts assembled in the
manufacturer's factory, must be tested to ensure
that it is watertight and operational. The safety
valve must be checked regularly to ensure that it
functions safely.

4. Anode and water quality

In accordance with DIN 4753, the magnesium anode
must be tested by the customer service department
after 2 years for the first time (after that annually)
and replaced if necessary.
In hard water areas scaling can be reduced by
restricting the water temperature. For descaling see
section 8.

We recommend that you have the system serviced
annually by a specialized company.
We recommend that the storage tank be cleaned
and checked annually.
Careful operation can save a considerable amount of
energy. Do not run the storage tank at more than
60°C, as this results in heat loss and limescale.
The ideal temperatures are 50-60°C.
