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 off power 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 fan 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 49. 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 "Maintenance Checklist":
1.
Check for the presence of the safety cable and shackle. The cable should be wrapped around the mounting structure, leaving as
little slack as possible. The shackle should be securely tightened and located on the topside of the mounting structure.
2.
Ensure all (12) mounting bolts are present and torqued to 40 ft·lb (54.2 N·m). Ensure the lower cable is between the brackets of the
lower yoke.
3.
Inspect motor terminals inside the junction box and tighten if necessary.
4.
Check all connections in the fan controller and tighten as needed.
5.
Check the gear reducer for oil leakage. If leakage is detected, contact Customer Service.
6.
Ensure airfoils are secured to one another by airfoil retainers.
7.
Ensure all (20) bolts securing airfoils to fan are present and torqued to 29 ft·lb (39 N·m).
8.
Inspect the lower safety cable to ensure it is secure.
9.
Inspect the airfoils and main motor unit for signs of damage or cracks.
10. Inspect all fan components for signs of corrosion, discoloration, pitting, and flaking of metal.
11. Check guy wires (if installed) for fraying or damage.
General preventive maintenance
Periodically perform the following maintenance procedures on your fan:
• 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
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.
