9 Installation of the Indoor Unit
9.1 Selecting the Indoor Unit Location
Warning
!
Danger of breakdowns or malfunction.
Observe the minimum clearances indicated in
Figure 8.1.
Note!
If a hole already exists in the wall or a refrigerant
pipe or condensed water pipe has already been
installed, the base plate should be mounted to
suit these conditions.
Recommendations
- Install the indoor unit close to the ceiling,ensuring
minimum clearances are met.
- Choose a position that will allow air to reach all parts
of the room evenly. Avoid beams, obstructions or
lights which would interfere with the airflow.
- Install the indoor unit at an adequate distance from
chairs or workstations in order to avoid unpleasant
draughts.
- Avoid installing close to heat sources.
9.2 Fixing the Mounting Plate
Carry out the steps described below:
• Place the mounting plate on the chosen installation
point.
• Level the plate horizontally and mark the position of
holes to be made on the wall.
• Remove the plate.
Warning
!
Danger of interference in the domestic installation.
Check that there are no electricity lines, pipes or
any other services which could be damaged
behind the spots where the holes are to be
drilled.
If other services are found, choose another
installation location and repeat the
aforementioned steps.
• Make the holes using a drill and insert the wall plugs .
• Place the mounting plate in position, level it
horizontally and fix it with the screws and the plugs.
Warning
!
Danger of breakdowns or malfunction.
Ensure that the mounting plate has been
correctly levelled. Otherwise, remove the plate
and re-fix it again correctly. Failure to do so
could lead to water leaks.
