FAN TROUBLESHOOTING
Disconnect and secure to the OFF position all electrical power to the fan prior to inspection or servicing. Failure to comply with this safety
precaution could result in serious injury or death.
1. Ventilator should be checked at least once a year. For critical or severe applications a routine check every two to three months is
suggested.
2. Guard to be kept free of debris. Guard is easily removeable for fan servicing and cleaning. No tools are required.
3. When moving or installing a belt, don’t force the belt over the sheave. Loosen the motor mount so that the belt can be easily slipped
over the sheave.
4. The belt, on belt driven units, should be removed and carefully checked for cracks, ply separation or irregular wear. A small
irregularity in the contact surface of the belt will result in noisy operation. If any of these defects are apparent the belt should
be replaced. At the same time check the sheaves for chips, dents or rough surfaces that could damage the belt.
5. The correct belt tension is important. Too tight a belt will result in excess bearing pressure, which can cause premature bearing failure
and may cause the motor to overload. Too loose a belt will result in slippage, which will burn out belts. Proper belt deflection should
be 1/64” (half way between sheave centers) for each inch of belt span when a force of approximately 5 lbs. is applied.
6. The belt alignment should be checked to be sure that the belt is running perpendicular to the rotating shafts. Motor and drive shafts
must be parallel.
7. A periodic inspection of all fasteners should be carried out to ensure they have not loosened due to vibration. Particular attention
should be paid to fasteners attaching the wheel to the shaft and those attaching the shaft to the bearing.
