Will the fan be installed so that the airfoils 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)?
If the fan is mounted at the same level or higher than a diffuser, the winglets
must be at a distance that is at least 1x the measure of the fan’s diameter. If the fan is mounted at the
same height or below a diffuser, the winglets must be at a distance that is at least 2x the measure of the
fan’s diameter.
Will the distance between multiple fans be at least 2.5x the fans’ diameter when measured from
the centers of the fans.
If installing on an I-beam, is the upper yoke the correct size? See page 11 for more information on
installing the fan on an I-beam.
If you ordered multiple fans, did you keep the parts of each fan together?
Some motors have the factory label, “This Unit Factory Wired for 460 VAC.” If you have a
200–250V or 100–125V controller, did you rewire the motor for proper use?
Do you have the correct power circuit for the fan controller? See page 2 for information on
selecting the correct circuit/fuse for the fan controller.
