unit spigots. The minimum straight air duct length is equal to 1 air duct diameter on intake side and 3 air duct diameters on outlet side.If the
air ducts are too short or not connected, protect the unit inner parts from ingress of foreign objects. To prevent uncontrollable access to the
fans, the spigots may be covered with a protecting grille or other protecting device with mesh side width not more than 12.5 mm.
