5. MAINTENANCE
5.3. Visually Inspect the Centrifugal Fan
Check the following during a visual inspection:
1. Ensure all guards are in place and in good working order.
2. Examine the centrifugal fan for damage or unusual wear.
3. Ensure motor is grounded through the ground lug attached to the control box.
4. Be sure all safety decals are in place and are legible.
5. Check that the air intake area is free of obstructions.
6. Inspect all moving or rotating parts to see if anything has become entangled in them. Remove any entangled
material.
7. Check all components. Replace damaged or worn parts before using the centrifugal fan.
8. Check tightness of bolts/nuts, fasteners, and hardware (re-torque if necessary).
5.4. Cleaning the Fan Blade and Housing
1. Check the housing and fan blade regularly for debris buildup drawn in by the airstream.
2. It is not recommended that the inlet screen be removed for cleaning. If the screen or inlet cone are
removed, they must be installed in the exact same place.
3. Use a pressure washer or hose to remove debris from housing and blades.
5.5. Servicing and Part Replacement
If there is any service/part replacement work required on the fan, it is important to reinstall the fan wheel
assembly in exactly the same position.
Failure to reinstall the fan wheel in the same position will cause premature wear, vibration,
and part failure.
Ensure the edge of the inlet cone (fit into the wheel cover) covers approximately 1/2 of the lip on the face plate
of the wheel.
Failure to reinstall the inlet cone and screen before operating the fan may result in serious
injury or death.
