2.7 ODU Installation
● The outdoor unit should be installed on a solid wall
and fastened securely.
● The following procedure must be observed before
connecting the pipes and connecting cables :
decide which is the best position on the wall and
leave enough space to be able to carry out
maintenance easily.
● Fasten the support to the wall using screw anchors
which are particularly suited to the type of wall;
● Use a larger quantity of screw anchors than
normally required for the weight they have to bear to
avoid vibration during operation and remain
fastened in the same position for years without the
screws becoming loose.
● The unit must be installed following the national
regulations.

Connecting the pipe
Screw the flare nuts to the outdoor unit coupling with
the same tightening procedures described for the
indoor unit.
