The fan is suitable both for horizontal or vertical mounting on the floor, on the wall or on the ceiling. While installing the unit ensure
convenient access for subsequent maintenance and repair. Secure the mounting bracket to the surface using screws with dowels of the
appropriate size (not included in the delivery set). Secure the fan on the bracket with clamps and bolts removed earlier.
Suspend it carefully. Make sure the unit is fastened securely prior to operation. Connect the air ducts of the appropriate diameter to the
fan (connections must be airtight). Air motion in the system must be in compliance with the direction of the arrow on the fan label.
To attain the best performance of the fan and to minimise turbulence-induced air pressure losses, it is recommended to connect the
straight air duct section to the spigots on both sides of the unit while mounting.
Minimum recommended straight air duct section length is equal to 3 fan diameters (see the "Technical data" section).
If the air ducts are shorter than 1 m or not connected, the internal parts of the unit must be protected 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.
