WARNING!
Danger of breakdowns or malfunction.
Observe the minimum assembly distances indicated in
Figure 8.3.
NOTE!
If a hole already exists in the wall or a refrigerant pipe
or condensed water pipe has already been installed,
the base plate can be mounted to adapt to these
conditions.

reach all parts of the room evenly. Airflow should not be
blocked by beams, installations or lamps.
- Do not install the indoor unit too close to chairs or
workstations in order to avoid unpleasant draughts.
- Do not locate the unit close to heat sources.
- All the securing elements used, and the ceiling itself, should
be stable enough to bear the weight of the unit safely.
