4.4.7 Aligning the connections of the heating
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 dis-
assembly or before assembly (see
▪ The heating lines must be connected free of tension via
the plug connectors. Establish a suitable strain relief es-
pecially when connecting with flexible lines (not open to
diffusion!) (see ).
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 stir-
rup 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
