CAUTION
The appliance must be placed in a
well-ventilated room, with a minimum surface
area that varies according to the amount of
refrigerant present.
To calculate the minimum area of the installation room,
proceed as described below:
– determine the total refrigerant charge (see section
“3.1.1 Refrigerant charge” of the outdoor unit
manual)
– identify the refrigerant charge value in the table
below and derive the respective minimum area
required for the installation room.

The following information can help you choose a suitable
location for the indoor unit.
The installation location must have the following
characteristics:
– good air circulation.
– ease of drainage.
– the noise emitted by the unit must not disturb other
people.
– stability and robustness - no exposure to vibration.
– sufficient capacity to support the weight of the
unit. If the structure is too weak, the unit can fall
and cause serious or fatal personal injury, material
damage and damage to the appliance.
– at least one metre away from any other electrical
device (e.g. TV, radio, computer).
– the space must be sufficient for installation and
maintenance operations.
– the space must be sufficient for connection of the
piping and drainage pipe.
– the air inlet and outlet must not be blocked.
– the airflow must be able to reach the whole room.
d
It is PROHIBITED to install the indoor
unit in the following locations:
– in a bathroom or laundry room, because
excess humidity can reduce its service life
and corrode the cables;
– near sources of heat, steam or combustible
gas;
– near flammable objects, such as curtains or
fabrics;
– near obstacles that could obstruct air
circulation;
– near the entrance;
– in an area that is not exposed to direct
sunlight;
– areas exposed to strong electromagnetic
waves;
