1.Check that the electrical power being supplied to the Fan matches the electrical Specifications on the Fan 

Decal.

2. Remove the Motor Access Cover.
3. Install an electrical disconnect within reach of each Fan installed.
4. Connect the cord to the motor according to the wiring diagram on the motor. Verify that the motor is 

connected for counter clockwise rotation (viewing the back of the motor, opposite the shaft end.)

Follow local, state, and national electrical codes for wiring.

Cut out one section of the Screen to route the cord out of the Fan: This will allow for the Screen to be 
removed without interfering with the Cord.

(See Figure 13)

. Attach the cord to the Wall using a Lag Screw 

and Cord Clip

.

 Allow enough slack in the cord to form a "drip loop" for moisture to fall away from the cord 

and not into the motor.

Hang the Rear Screen on the four tabs located in the corners of the Fan Mounting Flange. Position the Screen 
so that the Screen wire is captured between the 1/8" tall tabs and the Screen Clips. Rotate the two Screen 
Clips to capture the Screen 

(See Figure 14)
