SECTION II: INSTALLATION AND MAINTENANCE
If there is still a gap between the frame and the false ceiling, it should
be reduced by working on the brace nuts and lock nuts again:
II.2.4 External renewal air and treated air outlet in
an adjacent room (for models 60-85 only)
The side openings made it possible to create a separate external
renewal air inlet duct (5) and an air outlet duct in an adjacent room
(6).

you secure the respective safety cords:
II.2.3.4
Checking the Correct Installation of the
Frame-Grille Assembly (for all models)
The frame must not show signs of deformity caused by excessive
traction. It must be centred with respect to the false ceiling and, above
all, it must guarantee an airtight seal between the air inlet and outlet.
The figure shows the airtight seals (A-B), which prevent the air bypass
(A) and treated air leakage (B) inside the false ceiling. After installing
the assembly, check that the gap between the frame and the false
ceiling is under 5 mm.
Remove the external anti-condensation insulation, delimited by the
punching, and remove the pre-cut sheet metal panels using a punch.
Use a pencil to draw round the internal polystyrene (7), then cut it with a
cutter, taking care not to damage the heat exchange coil behind it.
II.2.4.1 Air Outlet in Adjacent Room (for models 60-
85 only)
An air outlet in an adjacent room requires the closure of at least the
mouth corresponding to the duct using the specific kit KCB (blocking
outlet mouths). An air recovery grille should be installed between the air
conditioned room (where the unit is installed) and the adjacent room
(near the floor if possible). Do not use the two pre-cut side openings on
the unit at the same time.

IMPORTANT!
Do NOT use active carbon or electrostatic filter kits
in the presence of ducts to the adjacent room.

4-6 mm
Use material suitable for operation at a constant temperature of 60 °C.
The ducts may be made from flexible polyester (with a spiral steel core)
or corrugated aluminium, clad externally with anti-condensation material
(fibreglass of 12 ÷ 25 mm thick).
Once installation is completed, the uninsulated surfaces of the ducts
must be covered with anti-condensation insulation (for example,
expanded neoprene of 6 mm thick).
IMPORTANT!
Failure to observe these instructions may cause
dripping due to condensation. The manufacturer
may not be held liable for any damage.
