The distance is selected depending on the installation conditions at the discretion of the installer.
The unit must be suspended to the ceiling on the threaded rod that is fixed inside a dowel.

Nut and
lock-nut
To attain the best performance of the unit and to minimise turbulence-induced air pressure losses, connect a straight air duct section on
both sides of the unit while mounting.
Minimum straight air duct length:
• equal to 1 air duct diameter on the intake side
• equal to 3 air duct diameters on the outlet side
If the air ducts are too short or not connected, protect the unit parts from ingress of foreign objects, e.g. by covering the spigots with a
protecting grille or other protecting device with mesh width not more than 12.5 mm to prevent uncontrollable access to the fans.
