General Maintenance
1. Fan discharge and approaches to ventilator should be kept clean and free from any obstruction.
2. Motors are normally permanently lubricated. Check bearings periodically. If they have grease fittings
lubricate each season. Use caution when lubricating bearings, wipe the fittings clean, the unit should be
rotated by hand while lubricating. Bearings should be lubricated every 2 months. The type of grease and the
amount of grease can is shown below. Caution: Bearings are sealed and over-greasing bearings can
cause damage to the bearings. Do not grease until grease comes out of seals. Only add the
appropriate amount of grease.
3. All fasteners should be checked for tightness each time maintenance checks are preformed prior to
restarting unit.
4. Fans require very little attention when moving clean air. Occasionally oil and dust may accumulate causing
imbalance. If the fan is installed in a corrosive or dirty atmosphere, periodically inspect and clean the wheel,
inlet and other moving parts to ensure smooth and safe operation.
