6. Trouble shooting

1. No air comes out of the fan
– Check the functioning of the motor, heat shield
and the fuses
– Check that the belts are not broken
2. Pressure rise and air flow too low
– Check the direction of rotation and the speed of
the fan
– If there is an undesirable duct bend in close proximity
to the outlet opening, then the connection losses
may be greater than expected -> check the ducting
and use baffle plates, if necessary
3. Fan vibrates
– Check the anti-vibration mountings
– Check that the impeller is not dirty
– Check the bearings
– Check the alignment of the belt drive pulleys
– Check that the bearings, hub and pulleys are properly
secured
4. Abnormal noise from bearings
– See Section 4.7 "Checking the bearings"
5. Repeated bearing damage
– Excessive bearing loads (i.e. belts have been
tightened too much)
– Poor or inadequate lubrication
– Impurities have entered the bearing
