Installation Checklist
Did a structural engineer approve the mounting structure? (See p. 8 for Big Ass Fans
approved mounting structures.)
Are you familiar with the function and use of the safety cable? (See p. 17 for information
on properly securing the safety cable.)
Will the fan be installed so that the blades are at least 10 ft (3.05 m) above the floor?
Will the fan be installed so that the blades have at least 2 ft (0.61 m) of clearance from
obstructions?
Will the fan be installed so that it is not subjected to high winds (such as from an
HVAC system or near a large garage door)? Big Ass Fans recommends that a fan be
installed at a distance (from HVAC equipment) no less than 2x the fan’s diameter when
measured from the center of the fan to the equipment. If the fan is mounted lower than an
HVAC supply and return diffuser’s discharge, the fan should be installed no less than 2x the
fan’s diameter from the diffuser when measured from the center of the fan to the diffuser. If
the fan is mounted at the same height or higher than a downward discharge diffuser, the fan
is recommended to be installed no less than 1x the fan’s diameter from the diffuser when
measured from the center of the fan to the diffuser.
Will the distance between multiple fans be at least 2.5x the fans’ diameter when
measured from the centers of the fans.
If installing to an I-beam, is the upper yoke the correct size? (See p. 11 for more
information on installing the fan to an I-beam.)
If you ordered multiple fans, did you keep the parts for each fan together? (It is critical
that the airfoils be properly matched with the motor unit.)
Do you have the correct power circuit for the fan controller? (See p. 24 for information
on selecting the correct circuit/fuse for the fan controller.)
