Start-Up Operation
DANGER
Disconnect and lock out all power sources before servicing equipment.
1. With the fan unplugged, rotate the propeller several complete revolutions by turning the fan pulley,
look for clearance between the propeller tip and the housing.
2. Replace all guards and check all fasteners to ensure they are tight.
3. When satisfied, energize the fan and make note of direction of rotation.
NOTE:
Make sure the propeller turns counterclockwise when viewed from inside the house and the
butterfly flaps should open completely.
4. The butterfly flaps are designed to stay open during fan operation and close when the fan is
de-energized.
5. If the propeller is turning backwards, the flaps will not open. If this is the case, refer to
Electrical
Connection
and switch the black and red wires as noted after de-energizing the fan.
6. Re-check the operation and when satisfied the fan is operating properly, follow the instructions
below.
Maintenance
DANGER
Disconnect and lock out all power sources before servicing maintenance.
1. Check the belt, pulleys and the bearings after every two (2) months of service.
2. The belt tensioner should be positioned between the second and the third notch as indicated by the
mark on the body of the tensioner. Under tensioning will result in belt slippage, over tensioning will
lead to premature belt and bearing failure.
3. The motor and shaft bearings are lubricated at the factory.
4. The motor bearings should never require lubrication over the life of the motor.
