with trouble-free operation.

Receiving Inspection

Installation
Mark and drill the bolt holes on the proper fan location (same as on fan base angles).
Locate and bolt firmly in place. (See installation instruction).

Maintenance of Motors
Motor bearings are pre-lubricated for 5-10 years. It is best to take the motor apart after the 5-10 years, and re-check bearings for replacement if necessary and repack with proper lubricant. If necessary to grease prior to this time, check the greasing specifications on the motor. Each motor has different grease or oil requirements due to the operation of the motor

Maintenance of Bearings
Sealed ball bearings, heavy duty cast iron pillow blocks, provided with means for lubricating.
Note: Units exhausting high temperatures should have bearings lubricated every three months and equipped with high temperature lubrication if necessary.

Pre-Maintenance Operation

1. Check all set screws and belts.
Check belts and pulley alignments.
Check maintenance of set screws and fan blade
Check tightness of inset screws and motor and fan pulleys.
Check tightness on belt tensions.

2. Belt tension:
Take up or relieve tension in belt so that there is approximately ¾" to 1" deflection under 3 pounds pressure based on 2 ½ to 3 ft. center on drive.
Adjustment of belt tension is accomplished by use of an adjustable motor base.

3. Operation:
After pre-operational checks, unit is ready for operation:
a) Start up unit; check rotation
b) If fan impeller is turning the wrong direction, reverse rotation per instruction
furnished by motor manufacturer.
