Secure Upper Safety Cable; Attach Main Fan Unit (To Lower Yoke) - BIG ASS FANS Pivot Installation Manual

3. Secure upper safety cable

The saftey cable is a crucial part of the fane and must be installed correctly. If you have questions, call
Customer Service for assistance.
Secure the safety cable to the I-beam or angle iron by wrapping the safety cable around it and securing the looped
ends with the shackle. The cable must be drawn tightly around the I-beam or angle iron, leaving as little slack as
possible. If possible, the shackle should be on the topside of the I-beam or angle iron. Securely tighten the shackle.

4. Attach main fan unit (to lower yoke)

CAUTION: When the fan is pivoted, the motor
should never be lower than the gearbox. This
will protect the motor in case the gearbox leaks.
Consider how the fan will eventually be pivoted
and position the lower yoke accordingly.
Attach the main fan unit to the lower yoke with the Main
Fan Unit Hardware.
Tighten the bolts to 40 ft·lb (54.2 N·m) using a torque
wrench and 3/4" socket.
