UNIT INSTALLATION
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 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.
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 installation
should be selected by a qualified technician.
