mounting structures.
Are you familiar with the function and use of the safety cable? See pages 12 and 14 for information
on properly securing the safety cable.

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 a Heating,
Ventilating, and Air Conditioning (HVAC) system or near a large garage door? If the fan is
mounted at the same level or higher than a diffuser, the 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
airfoil tips 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 you ordered multiple fans, did you keep the parts of each fan together?

Installing the Fan
WARNING: The fan weighs 70 lbs (31.8 kg). The fan should not be installed unless the structure on which the fan is to
be mounted is of sound construction, undamaged, and capable of supporting the loads of the fan and its method of
attachment. A structural engineer should verify that the mounting structure is adequate prior to fan installation. Verifying
the stability of the mounting structure is the sole responsibility of the customer and/or end user, and Big Ass Fans hereby
expressly disclaims any liability arising therefrom, or arising from the use of any materials or hardware other than those
supplied by Big Ass )DQVRURWKHUZLVHVSHFL¿HGLQWKHVHLQVWDOODWLRQLQVWUXFWLRQV
CAUTION: Do not install the fan from a single purlin or truss or junction box.
CAUTION: Unsupported angle iron spans should not exceed 12 ft (3.7 m).
1. Select proper angle irons
Follow the table below when selecting angle irons for fan installation. Note: Angle irons and angle iron hardware are not included with
the fan.

2. Pre-drill angle irons
Drill two Ø 9/16” (1.4 cm) holes exactly 5-1/2” (14 cm) apart in the centers of two angle irons.
Measure the distance between the mounting points of the roof structure that the angle irons will span. Measure the same distance on
the angle irons, and drill Ø 9/16” (1.4 cm) holes through each end of the angle irons. Drill holes in two angle irons if span is 8 ft (2.4 m)
or less. Drill holes in four angle irons if span is greater than 8 ft (2.4 m).

3. Secure angle irons (if span is longer than 8 ft)
If the angle iron span is 8 ft (2.4 m) or less, proceed to
step 4a on the following page.
c
b
If the angle iron span is longer than 8 ft (2.4 m), it is necessary to
use double angle irons.
Locate the center of the angle iron length. Drill Ø 9/16” (1.4 cm) hole
through the center of the vertical wall of the angle iron. Drill a total of
four angle irons.
Place two drilled angle irons back to back. Fasten the angle irons
together with customer-supplied Grade 8 hardware.
b
Align the angle irons to each other and tighten the bolts to 25 ft·lb

If installation requires double angle irons, i.e., span is greater than 8 ft (2.4 m), proceed to step 4b.
CAUTION: The angle irons must be fastened to the roof structure at each end.
Fasten the angle irons to the roof structure mounting points at each end with customer-supplied Grade 8 hardware as shown. Tighten
the hardware so that it is snug, but do not torque until the fan has been mounted to the angle irons. Note: Big Ass Fans
recommends orienting the angle irons so that the horizontal legs are facing each other. Refer to the illustration below.

receipt of the replacement part. Should the part be covered under warranty, you will not be charged for the replacement item; however,
you will be charged for the replacement part plus shipping if (1) the part is not under warranty because the source of failure is outside
the scope of the warranty, or (2) the warranty period has expired. If there is no warranty coverage, we will send you a detailed letter of
explanation. We also will charge you for the replacement item plus shipping and handling if you do not return the original item within 10
days of the receipt of the replacement item.
Instructions for returning the original item
1. Please use the return label that is included in the box containing the replacement part. The return shipment address is:
Big Ass Fan Company
ATTN: RMA#________
800 Winchester Road
Lexington, KY 40505
2. Use the packaging for the replacement part to return the original part.
3. Include the packing list we have provided which includes the RMA#.
4. If the part weighs over 50 lbs., you will be provided a prepaid Bill Of Lading. To schedule a freight pick up, please contact Customer
Service. We will only charge back the freight costs if the original part is not under warranty, or if you do not return the original
component within 10 days of receipt of the replacement.

Warranty claim form instructions
1. Complete Warranty Claim Form and Responsibility Agreement (see following pages) and fax them to 859-967-1695, Attn: Customer
Service. These pages will be faxed back to you for your records. The Warranty Claim Form will include our acknowledgment and a
Return Materials Authorization (RMA) number. 'RQRWUHWXUQDQ\LWHPZLWKRXW¿UVWEHLQJDVVLJQHGDQ50$E\%LJAss Fans
Customer Service.
2. No more than 10 days prior to the date you have made arrangements to replace the component part, call Customer Service
at 855-490-3048 to arrange for replacement component delivery and original component pickup. At that time, we will fax you a
written acknowledgment of your call that includes a reminder of the return instructions. Note: Even if you are not able to replace
the component immediately following your initial notice to us, returning the Warranty Claim Form and Responsibility Agreement
will effectively stop the warranty clock from running. You can then make the product exchange when you are prepared to do so.
However, the warranty period will continue to run until we receive these completed pages back from you, and no warranty will be
honored without receipt of these pages within the warranty period. We will not send out any replacement part until you have called to
let us know that you have scheduled installation of the replacement. This ensures that the replacement part is not lost or damaged
while awaiting installation, and that you are not billed for the replacement because you have waited too long to return the original
component (see Responsibility Agreement).
3. When you receive the replacement part, you have 10 working days to remove and replace the existing component and return it to us
at 800 Winchester Road, Lexington, KY 40505.
a. Upon receiving the replacement part, verify that replacement part order is correct. If order is incorrect or damaged, notify Big Ass
Fan Company within 24 hours after receiving order.
b. Use care unpacking the replacement component, as you will need to use both the packaging from the replacement part and the
packing list and a return address label included inside this packaging to return the original part. If the original packaging and
return documents are not used, you will be responsible for any damage incurred in transit as well as any additional costs involved.

any shipment that is returned via an unauthorized carrier. If you prefer, we can make all arrangements for delivery and pickup.
d. Fax a copy of the bill of lading or other tracking information to 859-967-1695 when the item has been shipped so that we know to
expect delivery of the original part.
4. If we do not receive the original part back within 15 working days from the date you receive delivery of the replacement, you will be
invoiced for the cost of the replacement part, plus freight, on Net 15 terms (see Responsibility Agreement), and this invoice will be
due and payable. If you subsequently return the replacement part to us after payment has been made, we will refund any payment
made for the replacement part, unless we subsequently determine that the part is not covered under warranty.
