Hydraulic installation
Flush the heating circuit thoroughly before
connecting the unit to the heating circuit.
Secure all connections to prevent twisting.
Cross-sections and lengths of the pipes for the
heating circuit are adequately dimensioned. The
connection line between the heat pump and the
building must also be taken into account.
Dimension the recirculating pump and piping
system such that the required throughput can be
achieved (
"Technical data/Scope of supply"
on page 17).
Recirculating pumps must be designed to run at a
.
Integrate the unit as shown in the hydraulic
diagram for the respective unit model.
The hydraulic system must be equipped with a

circuit via vibration decouplers. You must install
them to prevent the transfer of structurally borne
Insert the vent at the highest point of the heating
circuit.
ATTENTION
Components and lines for desuperheating
must be able to withstand temperatures up to
90°C.
Hydraulic connection is possible from below or at the
