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).

If it is intended to install ducting to an adjacent room, refer to § 4.4 for
removal of the pre-punched panel before installing the cassette.
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.
