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 are at least 10 ft (3.05 m) above the oor?

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 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® 120 V 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.

Pre-Installation (cont.)

Preparing the work site

The fan should only be installed according to the instructions described in this manual. Consult a structural engineer for installation methods not covered in this manual. For optional mounting methods, refer to the installation instructions included with the fan parts.

When surveying the work site, keep the following mechanical and electrical guidelines in mind.

Mechanical

• A suitable means for lifting the weight of the fan, such as a scissor lift, and at least two installation personnel will be required.

• If hanging the fan from angle irons, the minimum dimensions of the angle iron must be 2-1/2’’×2-1/2’’×1/4’’

(6.4 cm × 6.4 cm × 0.6 cm) and it cannot be longer than 12 ft (3.6 m). It must be secured to the structure. Do not mount the fan to a

single purlin, truss, or bar joist. Consult a structural engineer for installation methods not covered in this manual.

• To reduce the risk of injury to persons, install the fan so that the airfoils are at least 10 ft (3.05 m) above the oor.

• If mounting the fan in the vicinity of an infrared/radiant heater, it is recommended that the fan be mounted outside of the clearances recommended by the manufacturer of the heater and at a height equal to or above the shielding on the heating element with the controller on the opposite side of the heater. If mounting the fan below the heater shielding, all fan elements must be outside of the

clearances recommended by the heater manufacturer. The installation manual for the specic model of heater will typically provide

the minimum clearance to combustibles (MCC).

• Ensure the mounting location will not expose the fan to direct contact with water unless the fan is labeled, “Suitable for use in wet locations.”

• Adhere to the safety requirements in the table below when selecting where to mount the fan.

Safety requirement Minimum distances

Clearance

Blade height ≥10 ft above the floor

HVAC equipment ≥1x fan diameter if above diffuser. ≥2x fan diameter if below diffuser. Refer to the illustration below.

Fan spacing 2.5x fan diameter, center-to-center

Radiant/IR heaters See the manufacturer’s requirements for the minimum clearance to combustibles.

≥2 ft from all fan parts and ≥3 ft below sprinklers. The fan installation area must also be free of

obstructions such as lights, cables, or other building structure.

HVAC Diffuser

≥1x fan’s diameter (8 ft) (2.4 m)

HVAC Diffuser

≥2x fan’s diameter (16 ft) (4.9 m)

Electrical

• Identify the existing wiring to determine which wiring application is needed to install the fan.

• If installing a 120 V fan on a typical lighting circuit with one basic light switch in which the critical red conductor or “traveler” is absent, you will need to purchase the Limited Access Controller. Please discuss this option with your Big Ass Fans representative.

• Isis® is shipped with either a 110–125 VAC motor or a 200–240 VAC motor. The fan’s voltage is marked on the fan packaging and on the label on top of the main fan unit. The voltage cannot be changed during installation. Ensure your fan is the correct voltage prior to beginning installation.

Fan Operation (cont.)

Heating season

Isis®fansreturnheatfromtheceilingtooorlevelmoreefcientlythansmallerceilingfans.Formaximumenergysavings,thefan should be operated continuously during the heating season and should not be operated in reverse (clockwise). Big Ass Fans are

designedtooperateefcientlyatverylowspeeds,soturningthefanveryslowlyintheforwarddirection(counterclockwise)willprovide enoughairmovementtocirculatethehotairattheceilingdowntotheoorwithoutcausingadraft.

Stand directly below the tips of the airfoils with hand outstretched. If you feel a draft, slightly decrease the fan speed (0.5). Repeat until the draft is no longer noticeable.

Cooling season

The cooling effect created by the breeze from Isis fans keeps occupants comfortable with the thermostat at a higher setting. During the cooling season, every degree higher that the thermostat is reset reduces the energy consumed by the air conditioner by 1.5–2%. To minimize energy usage during the cooling season, operate the fan only when building occupants are present.

Increasethespeedofthefanuntildesiredairspeedormaximumfanspeedisreached.Inairconditionedfacilities,increasethe

thermostat setting by 2–7°F to save energy.

Changing the fan direction

CAUTION: When adjusting the fan direction selector switch, be careful not to damage internal components!

CAUTION: Do not insert foreign objects into the fan direction selector switch.

To reverse the direction of the fan, remove power from the fan. Select the direction of the fan using the fan direction selector switch.

Limited access application

CAUTION: The fan must operate on a dedicated circuit with a dedicated neutral. Failure to install the fan on a dedicated circuit will cause the fan to operate improperly.

Illustrated on the right is a typical lighting circuit with one basic light switch. The fan operational critical red conductor or “traveler” conductor is absent. For Isis® fan applications in which installing a 3-wire plus ground circuit (black, white, and red) is impractical or impossible, an optional limited access fan controller can be installed to eliminate the required red traveler conductor between the

controllerandthefan,allowingtheutilizationoftheexisting

2-wire plus ground circuit (black and white) shown on the right.

Note: This scenario is common in residences in which only a light circuit was previously installed.

38 Preventive Maintenance

WARNING: When service or replacement of a component in the fan requires the removal or disconnection of a safety device, the safety device is to be reinstalled or remounted as previously installed.

Please take a few moments each year to perform the following preventive maintenance inspection on your fan to ensure its safe and

efcient operation. Before contacting Customer Service, try resolving the issue using the troubleshooting procedures on the following page. If you have any questions, contact Customer Service. Note: Actual installation setup may differ from picture.

Annual preventive maintenance

Perform the following maintenance procedures each year using the Annual Maintenance Checklist on page 41.

1. Ensure all four mounting bolts are present and torqued to 25 ft·lb (33.9 N·m).

2. Ensure airfoils are secured to one another by airfoil retainers.

3. Ensure all 16 bolts securing the airfoils to the fan are present and torqued to 29 ft·lb (39.3 N·m).

4. Ensure all three (3) nuts securing the lower mount to the motor are tight.

5. Ensure all winglet hardware is secure.

6. Check guy wires (if installed) for fraying or damage (not shown in illustration below).

General preventive maintenance

• Verify proper fan rotation. To be effective, the fan must be turning counterclockwise when viewed from the oor.

• Dust airfoils and motor. If desired, use a gentle cleaner or degreasing agent to polish the airfoils. Do not use Clorox® or other chlorine

based cleaners! This could result in the release of toxic/fatal fumes. Do not use cleansers on the electronics enclosure.

• Check that the safety cable and upper mounting system are secure.

• Ensure the fan is not exposed to direct contact with water unless labeled, “Suitable for use in wet locations.”

• Observe the motion of the fan during operation. The fan should not wobble or precess. If any wobble is noticed, ensure the mounting

structure is rigid enough to support the fan and that the guy wires, if used, are sufciently taut. If guy wires were not used, Big Ass Fans suggests installing them. Contact Customer Service.

WARNING: Do not operate a fan with missing or damaged components. Please contact Customer Service.

General troubleshooting

Some issues can be resolved before requesting service. Review the below troubleshooting tips before contacting Customer Service for support.

Symptom Possible solution(s)

A popping noise is coming from the fan.

Airfoil noise is a result of airfoils that are

not tightened to the specied torque.

The fan will not start. Verify the following:

Switch off power at the service panel and lock the service disconnecting means. (If it cannot be locked, fasten a prominent warning device.) Tighten the airfoil hardware to 29 ft·lb (39.3 N·m). If popping still occurs, verify that the airfoils are not contacting each other. If the airfoils are contacting each other, please contact Customer Service.

• All wires are securely connected.

• The wall controller has power.

• Supply power is adequate and functional.

If the fan still does not start, contact Customer Service.

Note: Some motor noise is to be expected and is normal.

Replacement of products under warranty acknowledgment & return instructions

If you believe a part failed during normal operation and is covered under warranty, Big Ass Fans will ship a replacement part to you pursuant to your notice that you will be replacing the original part within 10 days. The replacement part will be shipped to you prior to our receipt of the item that failed, and prior to our evaluation of this part to determine the reasons for its failure and whether it is covered under warranty.

In order to evaluate the cause of the product failure, we will need you to return the original part to our ofces within 10 working days of

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.

Warranty Return Instructions (cont.)

Warranty claim form instructions

1. Complete Warranty Claim Form and Responsibility Agreement 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. Do not return any item without rst being assigned an RMA# by Big Ass 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

1-877-BIG-FANS 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.

Note: The RMA# must appear on the outside of the box being returned. Items without an RMA# will not be accepted.

c. Use the delivery service or one of the truck lines specied in the acknowledgement for return of the part. We will refuse receipt of

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.
