Fan Assembly Instructions

1. Put the upper canopy and lower canopy on the hanger

pipe assembly, facing in the proper direction. (See
Figure 1.)

NOTE: The fan is supplied with a 8” and a 22” hanger
pipe. If you are going to use the 8” pipe, first remove
the hanger assembly from the 22” pipe and install it on
the 8” pipe. Be sure that the nut is securely tightened
and the hairpin clip properly installed.

2. Pass the motor wires and safety cable through the

hanger pipe assembly and seat the hanger pipe in the
motor yoke. (See Figure 2.)

3. Align the clevis pin holes in the hanger pipe with the

holes in the motor yoke. Install the clevis pin and secure
with the hairpin clip (Figure 2). The clevis pin must go
through the holes in the motor yoke and the holes in the
hanger pipe. Push the straight leg of the hairpin clip
through the hole near the end of the clevis pin until the
curved portion of the hairpin clip snaps around the clevis
pin. The hairpin clip must be properly installed to prevent
the clevis pin from working loose. Pull on the rubber
grommet to make sure the clevis pin is properly installed.

4. Install and securely tighten the two 5/16-18 setscrews in

the motor yoke against the hanger pipe using the allen
wrench supplied. (Figure 2.)

5. Slide the lower canopy down the hanger pipe and

securely tighten the set-screw against the hanger pipe.
(See Figure 3.)

CAUTION: Blades come in balanced sets of three. Do
not mix blades if installing more than one fan.

NOTE: Install the blade gaskets between the blades and
the motor. (See Figure 3.)

6. Install the three blades onto the motor using spring

washers, M6 x 1/2" screws and blade gaskets supplied.
Securely tighten the six blade screws.
