FIXING THE PANEL

After installation of the unit, mount the grille using the 4 screws provided (fig.
12).
N.B.: It is very important to fix the grille in the right position for correct
!
connection of the receiver panel to the unit.
NOTES:
- To fix the panel only use the four supplied screws. Do not use other kinds of
screws or you could damage the condensate drain pan.
- Do not bend or narrow the unit piping.
- Do not remove the cap from the unit piping until immediately before connecting
the pipes.
- To prevent deformation of the air intake grille, do not overtighten the screws.

CHANGE OF AIR AND RECIRCULATION SYSTEM

-
Side knockouts allow connection of a duct for fresh air intake and for
conditioning an adjacent room.
-
Remove the external prepunched anti-condensate insulator and remove
the knockout panels using a punch.
FRESH AIR RENEWAL
Remove the polystyrene partition and insert the baffle plate.
Use material purchased locally that is suitable for continuous operation with
temperatures of 60°C. The ducts may be in flexible polyester (with steel spiral
core) or in corrugated aluminium lagged with anti-condensate material (fibreglass
12±25 mm thick). Upon completion of installation, surfaces that have not been
insulated may be covered with anti-condensate insulating material (e.g.: 6 mm
thick expanded neoprene).
Failure to comply with these instructions could cause dripping due to the
condensate; the manufacturer cannot be held responsible for any damage.
Any additional fan for external air intake (installer's responsibility) must be
connected to the terminal block as per the enclosed diagrams.
Fan operation is in parallel to the damper (electrothermal control valve), so that
it stops when the valve closes. Install an air inlet grille on the outside, with an
inspectable filter holding frame to prevent the entry of dust and leaves, which
could irreparably obstruct the unit heat exchanger coil.

AIR SUPPLY TO AN ADJACENT ROOM

Remove the polystyrene, taking care not to damage the behind heat exchanger
coil to the rear.
Do not use the two knockout side openings for air ducting to an adjacent room
simultaneously.
ATTENTION!
!
1) Ducting air to an adjacent room requires the closure of at least the
corresponding duct end.
2) When valves are installed, the air ducts to the "D" adiacent room
are unusable (pict. 13)
