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 (such as a tag) to the service panel.
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 resolving the issue using the troubleshooting procedures on page 41. If you
have any questions, contact Customer Service. Note: Actual installation setup may differ from picture.
Annual preventive maintenance
Perform the following maintenance procedures each year using the Annual Maintenance Checklist on page 39.
1. Ensure all upper mounting bolts are present and torqued to 25 ft·lb (33.9 N·m).
2. Ensure airfoils are secured to one another by airfoil retainers.
3. Ensure all 16 bolts securing the airfoils to the fan are present and torqued to 29 ft·lb (39.3 N·m).
4. Ensure the two (2) bolts securing the extension tube to the main fan unit are present and torqued to 25 ft·lb (33.9 N·m).
5. Ensure all winglet hardware is secure.
6. Check guy wires (if installed) for fraying or damage (not shown in the illustration below).
General preventive maintenance
• Verify proper fan rotation. To be effective, the fan must be turning counterclockwise when viewed from the floor.
• Dust airfoils and motor. If desired, use a gentle cleaner or degreasing agent to polish the airfoils. Do not use Clorox
based cleaners! This could result in the release of toxic/fatal fumes. Do not use cleansers on the electronics enclosure.
• Check that the safety cable and upper mounting system are secure.
• 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.
