MOUNTING AND SET-UP
ALL OPERATIONS DESCRIBED IN THIS USER’S MANUAL MUST BE PERFORMED BY
QUALIFIED PERSONNEL ONLY, PROPERLY TRAINED AND QUALIFIED TO INSTALL AND
MAINTAIN VENTILATION EQUIPMENT.
DO NOT ATTEMPT TO INSTALL THE PRODUCT YOURSELF.
IT IS UNSAFE AND IMPOSSIBLE WITHOUT SPECIAL KNOWLEDGE.
The units are manufactured in left and right versions, i.e. they can be serviced from the right or left side. Choosing the right arrangement
can improve the ease of installation, shorten the length of the ducts and reduce the number of air duct bends.

To attain the best performance of the unit and to minimise turbulence-induced air pressure losses, connect the straight air duct section
to the spigots 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 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.
Fasteners for fan 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.
Fasteners for installation should be selected by a qualified technician.
When installing the unit, it is necessary to ensure its slope of at least 3° towards the drainage pipes.
