Attach Column Mount And Tube (To Column) - BIG ASS FANS Pivot 180 Installation Manual

Mounting Method: Structural Stability Package (cont.)

8. Attach column mount and tube (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. Raise the torsion tube so that it is in the vertical position and the front
column mount is resting securely against the column. Secure the
torsion tube in place by securely tightening the two (2) bolts and nuts
to the lower stability brackets. Tighten the nuts to 40 ft·lbs (54.2 N·m).
Refer to the illustration on the right.
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 the nut to
40 ft·lb (54.2 N·m). Repeat this for the remaining three (3) 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 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.
5. Proceed to Safety Cable Mount Installation (p. 15).
