1. Install an electrical disconnect within reach of each Fan 

installed.

2.Remove the Motor Access Cover.
3. Remove the electrical knock-out nearest the Fan power 

supply outlet.

4. Install the Romex Connector and cord through the knock-

out selected before wiring the motor. 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.

5.Attach the cord to the Top Panel of the Fan using the Cord 

Clip, to keep the cord off the Shutter.

6.Allow enough slack in the cord to form a "drip loop" for 

moisture to fall away from the cord and not run into the 
motor.

7.Remove the slack in the cord between the Cord Clip and the Romex Connector and then tighten the Romex Connector.

The Bottom Panel is designed with 3 tabs, 

(Item 1, Figure below)

, to hold the Shutter. Slide the bottom of the Shutter 

into the Tabs, lean the Shutter into the Fan and lock the Shutter in place by rotating the (5) Shutter Clips 

(Item 2). 

 

Check the Shutter for proper operation. The Shutter Louvers must be able to open and close freely.
