Maintenance of the unit
The components of the heating circuit and the heat
source (valves, expansion vessels, circulating pumps)
should be inspected annually by a qualified technician
(heating or cooling system technician).
The hot water tank should be cleaned once each year
by qualified personnel (heating or cooling system techni-
cians). To do this, first empty the hot water tank. Then
remove the Styrofoam guard through the service hole
of the hot water tank. Screw off the flange cover of the
service hole.
Check the safety valve (provided by customer) for the
hot water tank at regular intervals. Since an external
current anode is built in, the anode requires no mainte-
nance.
It is a good idea to have a maintenance contract with a
heating installation company. The company will conduct
the required maintenance at regular intervals.
Malfunctions
In the event of a malfunction, you can detect the cause of
the malfunction via the diagnostic program of the heating
and heat pump regulator.

ATTENTION
Service and repair work on the components of
