14
WARNING: The following instructions assume that the customer's structure on which the fan will be mounted is of sound
construction, undamaged, and capable of supporting loads of up to 335 lbs (151 kg). It is the sole responsibility of the
customer to verify that the structure is adequate for fan installation. Big Ass Fans recommends consulting a structural
engineer prior to fan installation.
CAUTION: It is not recommended to mount a Big Ass Fan on a fabricated I-beam.

1. Mark centers of column and column mount

Measure the width of the column and mark the center. The column width must be between 8" (20.3 cm) and 15" (38.1 cm).
Measure the width of the front column mount and mark the center. Measure the width of the front safety cable attachment channel and
mark the center.

2. Attach column mount (to column)

A scissor lift or other suitable means for lifting the weight of the mount and torsion tube and at least two (2) installation
personnel are required!
1. Clamp the front column mount to the front of
the column with C-clamps so that the center
marks on both the mount and the column are
aligned and level.
2. Attach the front column mount by inserting
the ends of the threaded rod assemblies into
the front column mount. Secure it with the
Column Mount Hardware. Be sure the beam
clips and flange spacers (if used) are correctly
positioned on the rod and aligned with the
beam. Torque the nuts to 40 ft·lb (54.2 N·m).
Refer to the illustration below. Note: When
installing the threaded rod assemblies, hold
the locking hex nut while tightening the
outer Nylock nut to keep the assembly from
spinning.
3. Attach the column mount channels to the
threaded rod assemblies with the Column
Mount Hardware as shown below. Position the
square washer, flat washer, and lock nut as
shown. Torque to 40 ft·lb (54.2 N·m). Repeat
for the remaining threaded rod assemblies.
Note: Be sure the hex nuts are not contacting
the beam clips at this step.
4. Hand tighten the hex nut (A) nearest the beam clip (on the threaded rod).
Mark the 12 o'clock position on the this nut (A), and then turn it 3/4 to 1 full
turn with a 3/4" open end wrench. Tighten the inner nut (B) against the outer
nut (A). Refer to the illustration below. Repeat on the (3) remaining threaded
rod assemblies. Attach the front column mount by inserting the ends of the
assemblies into the front column mount. Secure it with the Column Mount
Hardware.
5. Proceed to Safety Cable Mount Installation (p. 15).
