4.2 Installation of air outlet duct
Lenght of air outlet duct:
■
As these Models are of low ducted type (about 10Pa), it’s a good rule to reduce as much as possible the
lenght of air outlet connection duct (max. 1-2m).
Arrangement for fixing the air outlet duct on Indoor Unit:
■
Fix 8 “L” brackets (see the Figure below) by bolts on Indoor Unit’s body. The bolts must not be too much
long, so as not to damage inner components of Unit.
Fixing the air outlet duct to Indoor Unit:
■
Fix the air outlet duct to “L” bracket already installed (see above) by using rivets, as it is shown in the
Figure below.
Notes:
1. Install supporting elements for air outlet duct, so as the weight this component does not rest on Indoor
Unit’s fixing elements.
2. Arrange an inspection hole - closed by a trap door - near air outlet duct, so that it can be easily
reachable for whatever operation of inspection and/or maintenance.
3. In case of installation in rooms where Indoor Unit’s noise level is needed to be reduced, carry out the
air outlet connection by adopting every possible precaution for sound insulation, and also use special
accessories on sale.
4. Insulate air outlet connection’s outside, in particolar along the way between the connection itself and
Indoor Unit’s body, to avoid condensation of humidity on false ceiling and dripping of water inside the
room.
