CAUTION
When working on the hydraulics, pay attention to the
installation 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
Hydraulic system plug
▪ 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
lines" [ 4 20]).

CAUTION
If the securing clips cannot be put on properly, the
couplings can be detached from their mountings to ensure
a very strong or continuous escape of liquid can occur.
▪ Before putting on a securing clip, make sure that the
securing clip engages in the coupling groove. To do so,
insert the coupling far enough into the mounting that
the groove is visible through the securing clip mounting.
▪ Insert the securing clip up to the end stop.
The connections of the heating inflow and return flow can be
directed upwards or backwards in order to adapt it optimally to the
structural conditions of the installation site.
