5. Operation and Maintenance
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 back to
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 the 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. Pillow block bearings should be re-lubricated every
30 operating days and/or after each wash down cycle with three (3) shots of grease or until
fresh grease is seen purging past seal. Lithium or lithium-complex based #2 NLGI grease must
be used. Other types of grease are incompatible with the factory lubricant and will damage
the bearing.
Incompatible grease or lack of service will void bearing warranty.
3. When cleaning the fans,
Do Not Spray
bearings, tensioner or motor directly with a pressure washer

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.
DANGER
Disconnect and lock out all power sources before servicing equipment.
CAUTION
DO NOT use a pneumatic or powered grease gun.
