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.
• The fan installation area must be clear of obstructions such as lights, cables, sprinklers, or other building
structure parts.
• Consult a structural engineer for installation methods not covered in this manual.
• 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 and the VFD must be remotely mounted. The installation manual for the specific model of heater
will typically provide the minimum clearance to combustibles (MCC).
Electrical Installation
• The installation of a Big Ass Fan must be in accordance with the National Electrical Code, ANSI/NFPA 70-2011,
and all local codes.
• Refer to specifications on page 1 for appropriate circuit requirements.
• The fan may begin to operate upon connection to power source. Do not apply AC supply power to fan until it is
fully assembled and in an acceptable upright position.

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. Up to two pedestals can be installed to heighten the range of airflow.
• Wall/Column. Yellow Jacket can be mounted to a wall or column using the Wall/Column Mount. The column can
be one of a variety of shapes, e.g., round, flanged, square.
• I-Beam. Yellow Jacket can be mounted to an I-beam using the Yoke Mount. Note: If the distance between the
I-beam and obstructions less than 65” (165 cm), the I-Beam Mount must be used. Contact Customer Service for
details.
• Bar Joists. Yellow Jacket can be mounted to bar joists using the Yoke Mount.
• Metal or Wood Superstructure. Yellow Jacket can be hung from a building structure using chains or cables of
rated strength to support the weight of the fan.
• Concrete. Yellow Jacket can be hung from a concrete structure using the Yoke Washer Assembly Kit and
installer-supplied hardware.
Note: Consult a structural engineer to determine the required mounting hardware when mounting to a wall,
column, metal or wood superstructure, or a concrete ceiling. The hardware must be of sucient strength to safely
support the fan. Big Ass Fans cannot provide specific installation details for these applications because of the
wide range of mounting surfaces, conditions, and fastening methods.
If hanging the fan using the Wall/Column Mount, the brackets must be positioned and mounted as shown below.
Do not mount the fan in any other position or orientation without consulting a structural engineer.
