Damages to motor and fan
The fan wheel must be in a good state of repair and perfectly clean; otherwise, it could be in permanent
imbalance when it rotates, leading to a breakdown.

The bearings have a specific service life. When they have reached the end of their service life, they must be
replaced by new bearings that are equivalent to the originals. Otherwise, the motor may be seriously damaged.
