Greenheck Fume Exhaust Fan FJC

Ensure power source is locked out before starting work.

Verify that belts and pulleys have been loosened and removed.

Confirm extended lubrication lines are disconnected at the bearing.

Read and follow all instructions carefully.

Ensure driven sheaves and belts have been removed.

Remove shaft black coating with a solvent similar to brake/carburetor cleaner.

Scribe a line around the shaft by both bearings and around the bearing base to the bearing support or write down the measurement from the end of the shaft to the bearings.

Loosen the inlet cone/ring bolts

Center the cone/ring on the wheel

Is additional adjustment required to maintain a constant radial gap?

Loosen the bearing bolts and center the wheel (if necessary)

Loosen the wheel hub from the shaft

Move the wheel to the desired position along the shaft

Is the transition between the inlet cone and wheel smooth?

Run each fan for a minimum of 30 minutes

Ensure all electrical and mechanical components reach operating temperature

Condensation and Load Redistribution

Check for any condensation formed on the fan components

Redistribute load on bearings by running the fan

Redistribute grease in motor and shaft bearings

Have the operating conditions of the fan changed?

Ensure the unit is attached to the designed system

Momentarily energize the unit to check wheel rotation

Is the wheel rotation in the same direction as the airflow at the outlet?

Does the wheel rotation conform to the rotation decal affixed to the unit?

Describe any issues noted during the check

Check for wear, tension, alignment, and dirt accumulation on V-belt drives

Are the sheaves free from grooves or wear?

Are all belts being replaced with a set of matched belts?

Loosen belt tension to remove belts without prying

Ensure slack in each belt is on the same side of the drive after replacement

Measure the belt span in inches
