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.

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

Mechanical

• The main fan unit is heavy. 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 (3.7 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).

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

To increase fan speed, turn the control knob clockwise toward

To decrease fan speed, turn the control knob counterclockwise toward

Note: The fan may take 30–60 seconds to start rotating after it is turned on. It is normal to see an initial slight jerking forward and

backward upon startup as the fan positions itself relative to the motor stator.

Changing the fan direction

Big Ass Fans recommends operating the fan in the forward (FWD) direction. The fan should be rotating counterclockwise when viewed from below.

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

located on the fan’s cover plate assembly. Reapply power to the fan. For fan status LED denitions, see page 32.

Moving at a low speed means less energy used for operation, translating into more energy savings year-round. Follow the procedures below to ensure the most efcient operation of your Big Ass Fan.

To ensure proper fan rotation:

1. Turn on the fan.

2. Verify that the fan is rotating in the counterclockwise direction (when viewed from below).

3. If the fan is not rotating counterclockwise, reverse the fan direction. See the previous page for instructions on changing the direction

of rotation.

Operating the Fan (cont.)

Heating season

In spaces with higher ceilings, E7, E10, and E12 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. Repeat until the draft is no longer noticeable.

Cooling season

The cooling effect created by the breeze from E7, E10, and E12 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 to 7°F to reduce energy consumption and save energy.

Preventive Maintenance

WARNING: Before servicing or cleaning unit, switch power off at the service panel and lock the service disconnecting means to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device (such as a tag) to the service panel.

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 page 31. If you

have any questions, contact Customer Service.

Annual preventive maintenance

Perform the following maintenance procedures each year using the Annual Maintenance Checklist on page 29.

1. Ensure all upper 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 12 bolts securing the airfoils to the fan are present and torqued to 29 ft·lb (39.3 N·m).

4. Ensure the two (2) bolts securing the extension tube to the main fan unit are present and torqued to 25 ft·lb (33.9 N·m).

5. Ensure all airfoil tip hardware is secure.

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

• 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.

11. With regard to electrical and electronic components provided by Big Ass Fans that comprise part of the products, including motors,

motor drives, and variable frequency drives, Big Ass Fans relies on the determination by the original manufacturer as to whether the failure of such component was the result of a defect. If the manufacturer of such component determines that there was no defect and therefore refuses to cover it under warranty, Big Ass Fans likewise will not warranty such item unless Big Ass Fans determines that the failure of such electrical or electronic component was the result of a defect of design, workmanship, or material within some other part of the products.
