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” documents.
Check to make sure that the cross-sections (diameters) and
lengths of the pipes for the heating circuit (including the
pipes laid in the ground between the heat pump and the
building!) 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 16 .
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.
Flush the heating circuit thoroughly before connecting
the unit to the heating circuit…
Dirt and deposits in the heating circuit can cause malfunc-
tions.
Install shut-off devices for the heating water outlet
(flow) and heating water inlet (return) on the heat
pump side…
By installing the shut-off devices, the evaporator and
condenser of the heat pump can be flushed, if neces-
sary.
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.
Hook the upper facing panels into the unit cover.
Screw the bottom onto the unit frame…
The air deflector hoods are now installed. You can
carry out the assembly and installation work on the
unit, and when finished attach the bottom facing panels.
(See “Electrical connection work”).
