To get the best performance of the unit and to minimize turbulence-induced air pressure losses, connect the straight air duct section to
the spigots on both sides of the unit while installing.
Minimum straight air duct length:
• equal to 1 air duct diameter on the intake side
• equal to 3 air duct diameters on outlet side
If the air ducts are too short or not connected, protect the unit parts from ingress of foreign objects.
To prevent uncontrollable access to the fan, the spigots may be covered with a protecting grille or other protecting device with mesh
