Flush the heating circuit thoroughly before connecting
the unit to the heating circuit…
NOTE.
Dirt and deposits in the heating circuit can cause
malfunctions.
Install shut-off devices for the heating water outlet
(flow) and heating water inlet (return) on the heat
pump side…
NOTE.
By installing the shut-off devices, the condenser of
the heat pump can be flushed, if necessary.
Connect the unit to the fixed piping of the heating
circuit via vibration isolators. You must install them to
prevent the transfer of structurally borne sound to the
fixed piping.
NOTE.
Vibration isolators are available as accessories.
The connections for the heating water outlet (flow) and
heating water inlet (return) are marked accordingly on the
unit.
For details on how to position the connections,

INSTALLATION / CONNECTION TO THE HEATING CIRCUIT
ATTENTION
Integrate the unit in the heating circuit as shown in
the hydraulic diagram for the respective unit model.
It is not possible to connect several heat pumps in
parallel.
“Hydraulic integration” document.
Check to make sure that the cross-sections (diameters) and
lengths of the pipes for the heating circuit are adequately
dimensioned.
The hydraulic system must be equipped with a buffer tank,
the required volume of which depends on your unit model.
See “Buffer tank” page “Buffer tank” on page 17
ATTENTION
When installing the connections, always protect the
connections on the unit from twisting, in order to
prevent damage to the copper pipes inside the unit.
