Annual preventive maintenance
Perform the following maintenance procedures each year using the “Maintenance Checklist”:
1. Check for the presence of the safety cable and shackle. The cable should be wrapped around the I-beam/angle irons leaving as little
slack as possible. The shackle should be securely tightened and located on the topside of the I-beam/angle irons.
2. Ensure all mounting bolts are present and torqued to 40 ft·lb (54.2 N·m). There are four bolts for direct mount installations, and 12
bolts for installations with extension tube.
3. Inspect motor terminations inside the junction box and tighten if necessary.
4. Check the gear reducer for oil leakage. If leakage is present, contact Customer Service.
5. Ensure all 12 bolts securing the airfoils to the fan are present and torqued to 29 ft·lb (39.3 N·m).
6. Ensure airfoils are secured to one another by airfoil retainers.
7. Ensure the bolts securing the winglets to the airfoils are securely tightened.
8.
Inspect for signs of corrosion, discoloration, pitting, or flaking of metal.
9. Inspect the airfoils and hub for signs of damage or cracks.
10. Check guy wires (if installed) for fraying or damage.
General preventive maintenance
• Check all connections in the fan controller and tighten as needed. Using a vacuum, remove all dust
and debris from the inside and outside of the controller.
•
Verify proper fan rotation. The fan should be turning counterclockwise when viewed from the
floor.
• Dust the airfoils, motor, and motor housing. If desired, use a gentle cleaner or degreasing
agent to polish the foils. Do not use Clorox
®
or other chlorine based cleaners! This could
result in the release of toxic/fatal fumes.
•
Observe the motion of the fan during operation. The fan should not wobble or precess.
If any wobble is noticed, ensure the mounting structure is rigid enough to support the
fan and that the guy wires, if used, are sufficiently taut. If guy wires were not used,
Big Ass Fans suggests installing them. Contact Customer Service.
WARNING: Do not operate a fan with missing or damaged
components. Please contact Customer Service.
Preventive Maintenance
WARNING: Risk of fire, electric shock, or injury to persons during cleaning and user-maintenance! Disconnect the
appliance from the power supply before servicing.
WARNING: Before servicing or cleaning unit, switch power off at service panel and lock the service disconnecting means
to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely
fasten a prominent warning device to the service panel, such as a tag.
WARNING: When service or replacement of a component in the fan requires the removal or disconnection of a safety
device, the safety device is to be reinstalled or remounted as previously installed.
Please take a few moments each year to perform the following preventive maintenance inspection on your fan to ensure its safe and
efficient operation. Before contacting Customer Service, try mending the issue using the troubleshooting procedures on page 43. If you
have any questions, contact Customer Service.
