3. Connect the Ducting
Tightly secure the ducting to the connecting inlet or outlet and seal
it with tapes.
The ducting leading towards the air outlet should be installed diag-
onally in a downward direction between 1/100 to 1/50 angle to
prevent rain water from sipping into the outlet’s opening.
Apply an additional layer of heat insulating material on surfaces of
the ductings, connecting points as well as the hanging fastener to
prevent it from condensation.
