CAUTION: If Pilot hole is used with the wood thread
hook, the pilot hole should be drilled no larger than
the minor diameter of the screw threads on the hook.
Do not put lubricant on the “J” hook. At least 1

” of

the screw threads should be secured Into the
structural wood joist. When the threaded bolt hook
is used, be careful to secure tightly with supplied
lockwashers and nuts. Attach the hook as instructed
and hang the fan.

CAUTION: Make sure that blades are attached as
shown.

9. This fan is equipped with the required “secondary

support” cable. This cable must be affixed to the
beam structures and securely clamped in such a man
ner to support the weight of the fan in the event the
mounting hook or other parts fail. After wrapping cable
around a structural member that will support 300
lbs., secure cable with supplied cable clamps as
illustrated in Figure 3. (Note: Any additional materials
needed for specific installations may be purchased
from your local distributor.)

NOTICE: Leave approximately 3” but no more than 5” of
slack on this safety cable to allow for possible fan
movement. Do not exceed more than 5” total slack.

IMPORTANT CAUTION: The safety cable must not be
placed between the rubber roller and hook but as
illustrated in Figure 3.

Assembly

This fan includes a “secondary support” safety cable fea-
ture that complies with existing C.S.A. (Canadian
Standards Association) requirements and all other
proposed safety regulations for overhead air movement
equipment. To insure proper installation of this important
safety feature, please read and follow these instructions
carefully.

1. Carefully unwrap the coiled safety cable and motor

lead wires.

2. At the motor yoke assembly (A), remove the cotter pin

and loosen the hexagon nut. Carefully remove spring
washer and the hexagon screw (E).

(See Figure 1)

3. Slide the upper canopy cover (B) (bell shaped) up the

rod. Slide the lower canopy cover (C) up to rod.

4. Feed the three wires and the safety cable through the

center hole in the steel yoke connecting piece above
the motor (A) and then continue feeding wires and
cable through the downrod until the wires and cable
come out at the upper shackle end (D).

5. Mount the downrod to the yoke (A) and replace the

hexagon screw. Secure the spring washer hexagon
nut and spread the coffer pin.

NOTICE: The safety cable should be taped to one side
of the yoke with electrical tape to prevent the cable from
resting on top of motor during running operation.

(See Figure 2)

6. Slide the lower canopy (C) to be a 1/4” minimum

height above the motor.

CAUTION: Do not allow the permanently installed
lower canopy to touch the revolving motor as dam-
age will occur. Make sure all wires are securely
placed to avoid rubbing against the motor.

7. Attach the three blades, curved side down to the motor

with the insulation pad mounted between the blade
and the motor. Make sure blade holder is flat against
motor platform when tightening blade nuts for secure
fit.

CAUTION: Blades must be fastened to the motor as
shown in Figure 1. DO NOT reverse blades when
installing.

NOTE: Blades are weight balanced per set. DO NOT mix
on multiple fan installations.

NOTE:Do not bend fan blade brackets.

WARNING: DISCONNECT CIRCUIT POWER BEFORE
MAKING ANY ELECTRICAL CONNECTIONS.

CAUTION: To reduce the risk of personal injury,
install the primary mounting directly from building
structure and use only the hardware provided with
the fan.

8. Before attaching the appropriate “J” hook to the

building structure member note the following:

IMPORTANT. WHEN MOUNTING THIS FAN, THE
SUPPORT BEAM MUST BE SUITABLE FOR A 50
POUND LOAD LIMIT.
