Connect the fixed piping of the heat source with
the relevant connections at the rear of the unit.
Use vibration isolators.
Vibration isolators must be installed to prevent
structurally borne sound transfer
to the fixed pip
-
ing.
Vibration isolators for the heat source are included
with the unit and have a stainless steel mesh.
Lay vibration isolators in the quadrant, as shown by
way of example in the following sketch:
Straight or extended hose laying of the vibration isola-
tors is not permitted.
19.1 Safety assembly
You must install the safety assembly for the heating
circuit. The safety assembly for the heating circuit is
included in the extra box.
The discharge from the heating water safety valve
must be drained according to the relevant standards
and regulations. Discharging the safety valve dis-
charge into the sewers is allowed only if fed via a a
funnel siphon, which must be accessible at all times.
The connection for the safety assembly is located on
the outside at the top rear of the unit.

19.2 Expansion vessel
The expansion vessel for the heating circuit and the
corresponding cap valve are included in the scope of
delivery. They must both be integrated in the heating
circuit on site in compliance with the relevant stand-
ards, guidelines and directives.
IMPORTANT
In conjunction with a multi-functional and/
or buffer tank with volume >200 l, always
install an additional, adequately-dimensioned
expansion vessel.
20 Domestic water heating
If the unit is to be used for domestic water heating, a
3-way changeover valve must be installed. This is not
included with the unit and must be ordered separately.
IMPORTANT
Only use the manufacturer’s original acces-
sories.
Domestic water heating with the heat pump requires
an additional heating water circuit (parallel) to the
heating circuit. When connecting, make sure that the
domestic hot water charge is not fed through a buffer
tank in the heating circuit.

21 Domestic hot water tank
If the heat pump is to be used for domestic water heat-
ing, you must integrate special domestic hot water
tanks in the heat pump system. Choose a storage
volume so that the required quantity of domestic hot
water is available even during a power failure.
NOTE
The heat exchanger surface of the domestic
hot water tank must be dimensioned so that
the heating output of the heat pump is trans-
ferred with minimum spread.
You can choose a domestic hot water tank from our
product range. They are optimally matched to your
heat pump.
