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), and 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 HCA60-80 only)
An air outlet in an adjacent room requires the closure of at least the mouth
corresponding to the duct using the specific kit (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.
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 aluminum, clad externally with anti-condensation material (fibre glass 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.
External renewal air, 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 aluminum, clad externally with anti-condensation
material (fibre glass 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.
Any supplementary fan for the suction of external air (to be fitted by the installer) must be connected to the terminal
board in keeping with the diagram below. The fan operates in parallel to the electro thermal regulation valve, so that it
stops when the valve closes.
