The fan is suspended to the mounting surface through the threaded rod fixed inside the expansion anchor.
The fan is intended for mounting to round air ducts and is installed between them.
The casing is equipped with fixing brackets for easier installation of the fan. While installing the unit, ensure convenient access for
subsequent maintenance and repair. Fasteners for ceiling mounting are not included in the delivery set and should be ordered separately.
While choosing fasteners consider the material of the mounting surface as well as the weigh of the unit (refer to the «Technical data»
section). Fasteners for unit mounting should be selected by the service technician.

To get the best performance of the fan 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 the 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 fans, the spigots may be covered with a protecting grille or other protecting device with mesh width not more than 12.5 mm.
