INSTALLATION MANUAL---Installation of the outdoor unit
The outdoor unit should be installed on a solid wall
and fastened securely.
The following procedure must be observed before co-
nnecting 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 aviod
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.
.
The outdoor unit should be installed on a solid wall and
fastened securely, of on the ground on a flat/level surface
like a concrete slab. The bolt size is M8*80mm
