Shutter Installation
1. Install the shutter after making sure the shutter vanes open upward and the shutter clips rotate easily.
2. After positioning all the shutter clips to hold the shutter tightly in place, manually operate the shutter to ensure
smooth and uninhibited operation. Adjust if necessary.
Shutter vanes MUST be installed to open toward the fan motor and upward as
shown in Figure 31. Attach shutter clips to the interior wall with #10 x 2" sheet metal
screws. Shutter clips can be adjusted as you tighten.

Start-Up Operation
Disconnect and lock out all power sources before servicing equipment.
1. With the fan unpowered, rotate the prop several complete revolutions by turning the fan prop, look for clear-
ance between the prop tip and the housing.
2. Replace all guards and check all fasteners to ensure they are tight.
3. Energize the fan, use controller to run the fan and make note of direction of prop rotation.
Note: Make sure the prop turns counterclockwise when viewed from inside the house.
4. If the propeller is turning backwards, de-energize the fan and refer to Power Connections Location and Wiring
Diagrams.
5. Re-check the operation and when satisfied the fan is operating properly, turn OFF power and insert the shutters
into the housing. Use the shutter clips to lock down the shutters.
Once the fan is fully installed, a test run should be done to be sure that it is operating correctly.
Safety glasses should be worn when testing fans.
