BIG ASS FANS Isis Installation Manual page 2

Installation Checklist
Did a structural engineer approve the mounting structure? See page 7 for Big Ass Fans-approved
mounting structures.
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 or airfoil tips 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 or airfoil tips must be at a distance
that is at least 2x the measure of the fan's diameter.
Will the fan be mounted where it will not come into direct contact with water? The fan should not
be mounted where it will come into direct contact with water unless it is labeled, "Suitable for use in wet
locations."
Will the distance between multiple fans be at least 2.5x the fans' diameter when measured from
the centers of the fans?
If you ordered multiple fans, did you keep the parts of each fan together?
What type of circuit does your building structure have, 3-wire or 2-wire? Isis is shipped with a
controller that is compatible with 3-wire circuits. If your building structure includes a 2-wire circuit, the
Limited Access Controller and Remote must be installed with the fan. If you require the Limited Access
Controller and did not note it at the time of order, contact Customer Service at 1-877-BIG-FANS.
