unfamiliar with wiring or in doubt, consult a qualified electrician.
• Do not use extension cord with fan.
• Do not remove covers while power is on.
• Do not use improper voltage source.
All fan controls and incoming power should be installed only by qualified technicians familiar with the requirements of the
National Electrical Code and local codes. Failure to follow these guidelines will void the manufacturer’s warranty.
All electrical controls are configured at the factory and are ready to use. No user adjustments are available. Follow the
included installation instructions when installing this device to ensure proper operation. Do not make any changes to
any part of the fan without first consulting Hunter Industrial Fan. Installation is to be in accordance with ANSI/NFPA 70:
National Electrical Code and local codes.
The user is responsible for compliance with all international and National Electrical Code requirements with respect to
grounding of all equipment. Many of the parts of this unit operate at line voltage
Before installing, servicing or cleaning the unit, switch power off at the service panel, lock the service disconnecting
means, and confirm Lockout/Tagout procedures are in place to prevent power from being switched on accidentally. When
the service disconnect means cannot be locked, securely fasten a prominent warning sign, such as a tag, to the service
panel.

SAFETY & PRECAUTIONS
CRUSH HAZARD
To prevent serious injury or death, ALWAYS attach the Retention Cable to the fan motor and secure to the building structure
on EVERY fan.
The Retention Cable, if installed per Hunter Industrial Fan specifications, can limit the distance the fan could fall in the
unlikely event of mounting system failure. Failure to install and to secure the Retention Cable will void your warranty.
Mark the Floor to Alert Personnel
When mounting a fan in an area where materials could be elevated and contact the rotating fan blades,
mark or paint the floor with a large crosshatched circle, similar to the figure to the left, to alert personnel of
the overhead fan locations.
Weight and Torque Considerations
Always mount fan directly to building structure that can withstand approximately double (2x) the maximum hanging weight
of the fan.
The hanging weight of a 14’ fan with a standard 2’ downrod is 121 lbs., the maximum hanging weight of a 14’ fan with a 4’
downrod is 135 lbs and a maximum torque of 75 ft lbs.
If there is any uncertainty about the potential for the building structure to withstand double the maximum hanging weight
of the fan, a professional structural engineer should perform a thorough evaluation of the building prior to purchasing
the fans. Hunter Industrial Fan provides guidelines for mounting fans; however, it is the sole responsibility of the building
owner and installer to ensure the safety of the mounting system and Retention Cable, the building structure is sound, and
the installation complies with all federal, state, and local codes.
Always use personal protective equipment.
You should always wear Personal Protective Equipment, such as a Hard Hat, Safety Glasses and a Fall Harness when
installing Industrial fans.
Damaged Equipment
Never operate or install any fans or fan accessories that appear to be damaged. Failure to follow this instruction can result
in death, serious injury, or equipment damage.
To reduce the risk of personal injury, do not bend the blades or blade holders when installing or cleaning the fan.
Do not insert foreign objects in between rotating fan blades.
Service
If the fan does not operate properly using the procedures in this manual, remove all power to the unit and contact our
Technical Department for further assistance at 1-844-593-FANS (3267).

FAN PLACEMENT
Fan Placement
ALWAYS mount fan so the bottom edge of blade to the floor is at least 10 feet from the floor and at
least 25% of fan diameter from the ceiling.
Always mount fans away from the following:
Sprinkler Systems
Prior to installing fans, review all codes applicable to sprinkler systems and fans to ensure code compliance and refer
to NFPA 13: Fire Sprinkler System Installation. In any installation where fire sprinklers are present, the fan should not
interfere with their operation.
o Fans should be located at least 3 feet below a sprinkler deflector.
o Fans should be centered between 4 adjacent sprinklers.
o The Industrial Control Panel should be connected to a fire relay system, which can stop the fans in the event a fire
occurs.
It is your responsibility that the installation complies with the applicable codes. For assistance, please call our Technical
Department at 1-844-593-FANS (3267).
Walkways and Mezzanines
If the building has elevated walkways or mezzanines, mount the fans so that a person cannot reach the rotating blades in
any way. Position fans so that the tips of the blades are at least 5 feet away from any area where a person may be able to
extend outward to reach them.
Lights and Skylights
If possible, avoid mounting fans directly below lights or skylights to avoid any strobe effect caused by moving blades.
There should be a minimum of 2 feet between the blades and any light fixture.
Air Discharge Locations
Fans should not be located directly beneath any air discharge. This includes air conditioning units and evaporative coolers.
Such equipment can be used effectively in conjunction with high-volume low-speed (HVLS) fans, but the discharge must
be located 2x the diameter from the swept area of the fan.
Windy Locations
Do not operate or install fans in outdoors or in areas exposed to wind. Failure to follow this instruction can result in death,
serious injury, or equipment damage.
Wet Locations
DO NOT locate fans where they may come into direct contact with water. These fans are suitable for mounting in damp
locations.
Other HVLS fans.
See the chart below to determine proper spacing between adjacent fans.
