BIG ASS FANS Basic 6 Manuel D'installation page 14

WARNING: Disconnect power to the installation locations before installing the fan and controller!
1. Assemble upper mount
If you are mounting the fan directly to angle irons without the upper mount, extension tube, and lower yoke,
skip to step 7b.
Attach the upper yoke brackets to the pivot bracket with the Standard Mount Hardware. Tighten the bolts to
40 ft·lb (54.2 N·m) using a torque wrench and 3/4" (19 mm) socket.
Loosely attach the mount brackets to the pivot bracket with the remaining Standard Mount Hardware. Install the
center bolts first. Do not fully tighten the hardware. This allows for angle adjustments after the upper mount is
attached to the mounting structure.
Standard Mount Hardware:
a. (10) 1/2-13 x 1-1/2" GR 8 Bolt
b. (20) 1/2" Flat Washer
