The unit is designed for mounting to a horizontal surface adjacent to the wall with the ready-made holes for the air ducts. Lower the
supports on the feet of the unit. During operation, the unit must stand on supports. By adjusting the height of the supports, achieve a
strictly horizontal unit position.
To get the best performance of the unit and to minimize turbulence-induced air pressure losses, connect the straight air duct section to
the unit spigots.
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 width not more than 12.5 mm. The unit
sections are equipped with feet with rollers and supports.
By turning the adjusting screw head, the unit can be mounted on rollers or on supports.
