4.6.1 Aligning the connections of the heating
inflow and return flow
The connections of the heating supply and return can be directed
upwards or backwards in order to adapt it optimally to the structural
conditions of the installation site.
The device is supplied with upwards aligned connections as
standard.
For this type of connection, the cover hood must be cut
out in the area of the heating lines.
Fig. 4-19 Cut-out for heating lines
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. 4.4.3 ).

2 Pull the two securing clips off the connection couplings
(
Fig. 4-20 , item C).
3 Pull off the two connection couplings ( Fig. 4-20 , item B).
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 Fig. 4-21 ).
▪ 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
Fig. 4-24 ).
