5. Operation
Start-up and Operation of the Butterfly Fan
1. With the fan de-energized, rotate the prop by turning the fan pulley, look for clearance between the
prop tip and the housing. Replace all guards and check all fasteners to ensure they are tight.
When satisfied, energize the fan and make note of direction of rotation. The prop should turn
counterclockwise when viewed from inside the house and the butterfly flaps should open
completely. They are designed to stay open during fan operation and close when the fan is
de-energized. If the prop is turning backwards, the flaps will not open. If this is the case, refer to
Figure 3J on Page 15 and switch the black and red wires as noted after de-energizing the fan.
Re-check the operation and when satisfied the fan is operating properly, follow the
instructions below.
2. Write down the date that the Butterfly Fan went into service and follow the maintenance schedule
as listed below:
a. Check the belt, pulleys and the bearings after every two (2) months of service. The belt tensioner
should be positioned between the 2
nd
and 3
rd
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.
b. The motor and shaft bearings are lubricated at the factory. The motor bearings should never
require lubrication over the life of the fan but the fan shaft bearings should be greased after every
2-3 months of use, using the zerks on top of the pillow blocks. Only use a small amount of lithium
soap base grease after cleaning the zerks. Contact your fan distributor for the proper grease.
3. When cleaning the fans, Do Not Spray bearings, tensioner or motor directly with a pressure washer
as this Will lead to premature failure of these components. After cleaning the fan, simply wipe these
parts with a clean rag to remove dirt and debris. Failure to follow these instructions will void the
warranty on these components.
Disconnect and lock out all power sources before servicing equipment.
