Side openings are provided for installing separate ducts for
outside air intake and treated air distribution to an adjacent
room.
Use a punch to remove the condensation protection insulation
and the pre-punched panels from the openings.

TAKE CARE not to damage the heat exchanger coil
located behind the openings.
Plug the gaps between the ducts and the opening edge with
anti-condensation insulation.
Use material which can withstand a continuous operating
temperature of 60° C. The ducts can be of the flexible type
with a spring core or of corrugated aluminium, covered
inside with an insulating material (12 to 25 mm thick glass
fibre).

Fix the screws to fix the corner irons
In the event that the suspended ceiling is 300 mm from the
ceiling (minimum permitted height), it might be necessary
to temporarily remove some of the suspended ceiling T
supports.
Position the cassette on the suspended ceiling support
rods, and start by tightening the side mounting bolts, then
the threaded rods nuts and lock nuts, after having set the
cassette level, maintaining a gap of around 10 mm between
the metal chassis and the suspended ceiling.
When the installation is finished, all the surfaces of the
non-insulated ducts must be covered with anti-condensation
insulation material (6 mm thick expanded polystyrene or
expanded neoprene). Fireproofing classification: M1)
IF THE ABOVE INSTRUCTIONS ARE NOT FOLLOWED,
CONDENSATE LEAKS MAY OCCUR.
Distributing air to an adjacent room requires one or two
of the corresponding ducts' air distribution flaps to be
closed.
A decompression grille must be fitted in the partition between
the air conditioned room (where the cassette is installed)
and the adjacent room.
