Commissioning / Frost Protection /
Servicing
The installation and initial commissioning may be performed only by a recognised
installation company.
Flush pipes and tank thoroughly after installation, fill tank with water. Open warm water
flow tap until water runs out and check safety valve by introducing air.
It is essential to fill and completely bleed tank before the first start-up!
Attention: The max. operating pressure is 10 bar and must not be exceeded!
Operation with charging pump:
Set switch at control SP-1E... to position „charging pump" and set tank temperature
controller to desired temperature (60°C max.). When connecting an electronic tank
sensor, the tank temperature is set at the boiler control.
Operation with electrical auxiliary heating system E2 / E4,5 / E6
Set tank temperature controller of the heating control to 20°C.
Turn tank temperature controllers of the electrical auxiliary heating system to desired
temperature (60°C max).
In case of prolonged absence, the tank temperature controller can be turned completely
to the left (counter-clockwise). The frost protection function remains active.
The unit must be checked by a professional company every 2 years.
In case of a built-in magnesium anode, the protective effect is based on an elec-
trochemical reaction, which results in a decomposition of the magnesium. For
this reason, it must be checked every 2 years and replaced if necessary.
When changing the anode, the tank pressure must be relieved.
Close cold water connection, switch off circulating pump and open any hot water tap
in the house.
When using a built-in impressed-current anode, no servicing is required.
After removing the flange the seal has to be replaced prior to reassembly, torque of
