Servicing
Magnesium anode
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 electrochemical 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.
Frost protection
In case of prolonged absence, the tank temperature controller can
be turned completely to the left (counter-clockwise). The frost
protection function remains active.
Commissioning
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).
After removing the flange the seal has to be replaced prior to
reassembly, torque of nuts 20-25 Nm.
