Assembly Instructions
1. Remove the fan motor and housing assembly from
styrofoam packaging and position it so that the top
of the motor is facing you.
2. Separate, untwist and unkink the three motor
leads. Route the motor leads through the hanger
ball/downrod assembly and seat the downrod in the
motor coupling.
3. Align the clevis pin holes in the downrod with the
holes in the motor coupling. Install the clevis pin
and secure with the hairpin clip. The clevis pin
must go through the holes in the motor coupling
and the holes in the downrod. 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 hanger ball to make
sure the clevis pin is properly installed.
4. Install the setscrew (supplied in loose parts bag) in
the motor coupling. While pulling up on the hanger
ball, tighten the setscrew using the 5/32" setscrew
wrench (supplied).
NOTE: The setscrew must be properly installed as
described above, or fan wobble could result.
5.Remove the hanger ball by loosening the setscrew
in the hanger ball until the ball falls freely down the
downrod. Remove the pin from the downrod, then
remove the hanger ball. Retain the pin and hanger
ball for reinstallation in step 8.
6.Screw two 1” threaded studs (provided) into the
motor. Leave approximately 7/8” of the stud extend-
ing above motor. Slide the motor cover over the
downrod and rotate the cover until the threaded
studs protrude; install two knurled knobs (supplied)
to secure the cover.
NOTE: Make sure the red and brown leads are
capped with wire connectors and are completely
inside motor cover and not pinched between the
motor cover and motor.
7.Position the ceiling cover over the downrod. Be sure
the cover is oriented correctly, with the large open-
ing at the top.
8.Reinstall the hanger ball on the downrod as follows.
Route the motor leads through the hanger ball and
slide the hanger ball over the downrod. Install the pin
through the holes at the top of the downrod and slide
the hanger ball up the downrod, aligning the ball so
the pin is captured in the groove in the top of the
hanger ball. Pull the hanger ball up tight against the
pin and securely tighten the setscrew in the hanger
ball. A loose setscrew could create fan wobble.
