The dimensions of the air ducts must be determined taking into account the air flow and the static pressure available from the unit.
Connect the ducts to the discharge ports of the fans using flexible connections, preventing transmission of vibrations and noise.
Protect the external ducts against bad weather, as well as keep the joints and openings airtight.
The air supply ducts of the evaporator that pass through unconditioned environments must be thermally insulated.
