UNIT INSTALLATION
To attain the best performance of the unit and to minimize turbulence-induced air pressure losses, connect the straight air duct section
to the spigots while installing.
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 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.
The unit must be mounted on a flat floor.
Installing the unit to an uneven surface could lead to the unit’s casing distortion and operation disturbance.
Do not expose the unit to direct sunlight.
READ THE USER'S MANUAL BEFORE INSTALLING THE UNIT.
