IT IS COMPULSORY TO INSTALL INTO THE ROOM AN APPROPRIATELY SIZED
OVERPRESSURE DAMPER TO ALLOW THE ROOM AIR EXHAUSTION DURING FREE-COOLING
OVERPRESSURE DAMPER – Not supplied
During free-cooling operation, the air conditioner supplies ambient air directly into the room, this causes
an increase in air pressure inside the room.
The overpressure damper avoids the increase in pressure in the room.
The damper must be installed at the highest point of the room to expel excess hot air to the outside.
Install the damper if possible in opposite position to air conditioner.
Air exhaustion must be protected with a rain cover and a grille (at Customer care).
