Annual Preventive MaintenanceWARNING: 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 (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.

To be performed annually: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 (4x for direct mount installations and 12x for installations with extension tube) are present and torqued to

98 ft·lbf (133 N·m). 3. Inspect motor terminations inside junction box and tighten if necessary.4. Check gear reducer for oil leakage. If leakage is present, contact Customer Service at 1-877-BIG-FANS.5. Ensure all bolts (20x) securing airfoils to fan are present and torqued to 29 ft·lbf (39 N·m).6. Ensure airfoils are secured to one another by airfoil retainers (10x).7. Ensure bolts securing winglets to airfoils are securely tightened.8. Ensure hub safety clips (6x) are present and torqued to 35 ft·lbf (47 N·m). The bolts securing the safety clips to the hub are located

on the faceplate underneath the fan.

Additional Considerations• 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 counter-clockwise when viewedfromthefloor.

• Dust 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.

WARNING: Do not operate a fan with missing or damaged components. Please contact Customer Service at 1-877-BIG-FANS.
