4. The units mounted in the ceiling must discharge the air outdoors, not in the space between the
false ceiling and the ceiling itself, using a flexible pipe and the corresponding anti-return valve.
NOTE: If the unit is mounted on the piping (not included), it is necessary to install this piping in
such a way as to avoid the entry of gases from gas-burning appliances or other fuel-burning
appliances into the room.

The fan is double insulated (class II) and
does not need to be earthed.
L – phase
N – neutral
The connectors are located on the fan base
to ensure the degree of protection (IP)
against water splashes. The fan is
permanently supplied with voltage by
means of a 2 conductor-cable of min 1 mm
section each.
