Position and secure the ducts in the connection hoses and apply aluminium tape (îš¿eld-supplied) around the connection to
avoid air leaks. The duct connection hoses have a previously installed sealing system.
Suspend the ducts from the ceiling so that the weight does not rest on the unit.
Cover the two outdoor ducts with suitable heat insulation material
to prevent the formation of condensation.
Secure the exible air duct to the outsides of the hoses supplied
with the unit.
Do not install ducts along complex layouts or sharp bends. The
volume of air may be reduced, leading to abnormal circulation
noises. Particularly avoid the following situations:
• A: extremely tight bends.
• B: multiple bends.
• C: bends next to the outlet.
• D: extreme reduction of the diameter of the connected ducts.
