WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT
MAINTENANCE AND REPAIR.
BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN
OBJECTS (E.G. FOIL, PAPER).
Prior to mounting the unit:
•
Make sure that the fan impeller rotates freely.
•
Make sure there is no condensation on the motor.
•
Check the electrical resistance of insulation between the motor windings and between each winding and the motor frame.
After installing the unit make sure that the fan impeller rotates freely.
The fan is installed between rectangular air ducts.
Connect the fan to air ducts with bolts and nuts.
The fan must be fixed on independent hangers so that it does not press the flexible joint (purchased separately) or the air duct.
It is recommended to suspend the fan to the ceiling using steel reinforcement and threaded rods, or using perforated galvanized plates
and connecting them to the fan flanges or to an auxiliary structure.
The fan may be installed in any position in consideration of the air flow direction (indicated by the arrow on the fan casing).
When placed under the ceiling to access the terminal box and motor, it is desirable to install the fan with the motor downwards.
Install a flexible joint (purchased separately) on both sides of the fan.
To protect the fan and air duct from dust, it is recommended to install a filter upstream of the fan (purchased separately).
If the fan is mounted so that a person or object can come into contact with the impeller, a protective grille must be installed (purchased
separately).
It is recommended to install a 1.5 m long straight air duct at the fan outlet.
