6 Installing the hydraulic
connections
IMPORTANT
Dirt and deposits in the (existing) hydraulic system
can cause damage to the heat pump.
► Ensure that a sludge separator is installed in the
hydraulic system.
► Rinse the hydraulic system thoroughly prior to es-
tablishing the hydraulic connection of the heat
pump.
IMPORTANT
Damage to the copper pipes due to unacceptable
loading!
► Secure all connections against twisting.

Cross-sections and lengths of the pipes for the
heating circuit are adequately dimensioned. In do-
ing so, ensure that the connection pipework be-
tween the heat pump and hydraulic station are also
taken into account.

Freely pressing the recirculating pump produces
at least the minimum throughput required for the
device type (

► Route all hydraulic connections as fixed piping
and attach them via a fixed point to the wall or
ceiling at a maximum distance of 20 cm from the
centre of the respective unit connection.
► Insert the vent at the highest point of the heating
