inflow and return flow
CAUTION
When working on the hydraulics, pay attention to the in-
stallation position of the O‑rings to avoid damaging them
and causing leaks.
▪ Always place O‑rings on the part to be inserted after
disassembly or before assembly (see
▪ The heating lines must be connected free of tension via
the plug connectors. Establish a suitable strain relief
especially when connecting with flexible lines (not open
to diffusion!) (see Fig.
CAUTION
If the plug brackets cannot be put on properly, the coup-
lings can be detached from their mountings to ensure a
very strong or continuous escape of liquid can occur.
▪ Before putting on a plug bracket, make sure that the
stirrup engages in the coupling groove. To do so, insert
the coupling far enough into the mounting that the
groove is visible through the plug bracket mounting.
▪ Insert the plug bracket up to the end stop.
The connections of the heating inflow and return flow can be direc-
ted upwards or backwards in order to adapt it optimally to the struc-
tural conditions of the installation site.

The device is supplied with upwards aligned connections as stand-
ard. The following conversion steps are required in order to direct
the connections to the rear out of the device:
1 Remove the protective cover and top thermal insulation
(see Chap. 3.4.2).
