1. Square washers are included and are only used if you are mounting the fan to angle irons. The number of square washers needed depends on the number of angle irons used.
2. Guy wires are only included if the fan’s lateral movement needs to be restrained. Big Ass Solutions recommends using guy wires if the extension tube is four feet or longer, if
the fan is exposed to high winds or similar conditions, or if the fan is near building structural components.
Parts
Check that you have all of the required parts before beginning installation.
If you ordered multiple fans, be
sure to keep the components of each fan together. Each fan has differently rated components that are not
interchangeable.

1. Spacers are only used with I-beam installations when the beam flange exceeds 3/8 inches.
2. The upper mount may differ from the picture. Confirm that you have the appropriate mount for your roof pitch.
3. The safety cable is preattached to the extension tube or packaged separately if the extension tube was not ordered.
4. An AirFence™ is installed on the midsection of each airfoil. Check each airfoil to ensure the AirFence is properly secured.
5. Powerfoil winglets are standard. Powerfoil Plus winglets are only available if ordered.
6. The resistor is needed only for 0–10 V devices controlled by a 4–20 mA analog signal when connected.
