FAN DIAGRAM The diagram below shows a Yellow Jacket with one pedestal and portable base. If you ordered the Wall/Column mount, Yoke mount, Yoke Washer Assembly kit, or an extra pedestal, see the appropriate installation instructions. A. Protective Cage and Housing. The steel cage and housing protect both the fan and users during operation. B. Fan Motor (not shown). The fan motor powers the fan and controls the fan’s speed, and is located on the backside of the fan. C. Position Locking Mechanism (not shown).
PREPARING THE WORK SITE When surveying the work site, keep the following guidelines in mind. Mechanical Installation • The Yellow Jacket weighs, at maximum, 105 lbs (48 kg). Practice proper lifting techniques when assembling the fan. • If you ordered the oscillator, review the installation guide packaged with the oscillator before beginning installation. • If mounting the fan to an I-beam, the I-beam must have at least 65” (165 cm) of clearance below.
MOUNTING OVERVIEW CAUTION: It is your responsibility to comply with all local and national codes and regulations regarding mounting procedures! Before mounting the fan, ensure you have the proper mounting equipment for your mounting location. Depending on your airflow needs and your building structure, the Yellow Jacket can be mounted using one of the following methods: • Portable Base. The portable base allows Yellow Jacket mobility around a workspace to create airflow where it is needed most.
MOUNTING METHOD: PORTABLE BASE WARNING: To reduce the risk of fire, electric shock, and injury to persons, the fan must be installed with the supplied mounting hardware. Other mounting hardware cannot be substituted. 1. Attach wheels (to portable base) To install the wheels, insert the screw through the center of the wheel. Thread the hex nut onto the screw approximately 1”, and then insert the screw (attached to the wheel) into the hole on the fan base until it is tight.

2. Pre-drill angle irons Drill two ø9/16” (1.4 cm) holes exactly 5-3/8” (13.7 cm) apart in the centers of two angle irons. If the motor frame will be mounted directly to the angle irons, drill two ø9/16” (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 then drill two ø9/16” (1.4 cm) holes through the ends of the angle irons.
4a. Fasten single angle irons to roof structure mounting points ATTENTION If installation requires double angle irons (span is greater than 8 ft), proceed to step 4b. Fasten the angle irons to the roof structure mounting points at each end with installer-supplied Grade 8 hardware. Do not tighten the angle iron hardware 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.
5. Attach upper yoke (to angle irons) CAUTION: Beam clips and spacers are never used when mounting the fan to angle irons! ATTENTION The angle irons should be aligned with the outermost holes in the upper yoke. Secure the upper yoke directly to the angle irons with the Upper Yoke Hardware.

11. Install remaining guy wires CAUTION: Over-tightening the guy wires could throw the fan off balance. Wire Rope Clip Repeat steps 9–10 to install the three remaining guy wires. Evenly cinch all four guy wires into place using the Gripples®. The guy wires should be taut and evenly spaced around the extension tube. Once all of the guy wires are taut, secure their loose ends with the wire rope clips and torque to 4.5 ft·lb (6.1 N·m).
MOUNTING STRUCTURE: WOOD OR METAL SUPERSTRUCTURE WARNING: 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.
MOUNTING STRUCTURE: CONCRETE WARNING: 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.
1. Prepare angle iron brackets All hardware, including angle irons, is installer-supplied. Select mounting hardware that is of sufficient strength to support the weight of the fan. Big Ass Fans recommends using (4) 1/4” Dia. Hilti Kwik Bolt 3 Mechanical Anchor with a minimum embedment depth of 1-1/8” to secure the angle iron to the concrete; however, you must consult a structural engineer to determine the best method of attachment. Cut two 3.5” (89 mm) x 3.5” (89 mm) x 0.25” (6.4 mm) angle iron pieces to 6.
4. Attach chain or cable Ensure the position locking pin is secured prior to attaching the yoke to the chain or cable. ATTENTION Special consideration must be given to external air influences such as HVAC discharge units, exhaust fans, open doors, other fans, etc. Install the eyenut on the fan yoke with the Yoke Washer Assembly Kit. Secure the chain or cable to the eyenut, and then secure the other end to the angle iron brackets.
POSITIONING THE FAN CAUTION: When setting the position, be careful not to pinch hands or fingers between the fan yoke and housing! Yellow Jacket can effectively control the direction of airflow by setting the position of the fan cage and housing. To adjust the position of the fan, pull the position locking pin from the locking plate, tilt the fan to the desired position, and then reinsert the pin into the appropriate notch on the locking plate.
ELECTRICAL INSTALLATION WARNING: To reduce the risk of electric shock, wiring should be performed by a qualified electrician! Incorrect assembly can cause electric shock or damage the motor and the controller! Hazard of electrical shock! WARNING: The installation and usage of a Big Ass Fan must be in accordance with the requirements specified in this installation manual and with any additional requirements set forth by the national electric code (NEC) and all local codes.
FAN SPEED CONTROL OPERATION CAUTION: The fan may begin to operate upon connection to power source. Do not plug in the fan until it is fully assembled and in an acceptable upright position. Starting, stopping, and speed control ATTENTION Ensure the position locking pin is secure in the locking plate prior to fan operation. The speed control knob is located on the side of the fan, and turns the fan on/off and controls fan speed.
REMOTELY MOUNTED SPEED CONTROL WARNING: Disconnect power to the fan prior to wiring the remotely mounted speed control. The remotely mounted speed control is an optional accessory used to operate a fan that is mounted in an inaccessible location. Fifteen (15) feet of cable is provided with the remotely mounted speed control; however, the control can be mounted up to 50 ft from the location of the fan using installer-supplied cable.
