In a world full of
impersonators, be an
original. We invented the
ceiling fan, and we stand
behind our products.
The Hunter legacy is not
only about quality—it’s
about longevity. We
invented the ceiling fan.
We build fans that last,
fans that are designed as
fans. We design our fans
while considering each
person in the process—
from the installer to the
owner.

unfamiliar with wiring or in doubt, consult a qualied electrician.
• Do not use an 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 qualied 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 congured 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 rst consulting
Hunter Industrial. 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 conrm
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.
To reduce the risk of electric shock, serious injury,and death,only use this unit as intended by the manufacturer.If you have any questions,
call our Technical Department at 1-844-593-FANS (3267).
ELECTRIC SHOCK HAZARD
5007479

5
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 specications, 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.
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.
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).
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.
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 maximum hanging weight of a 24’ fan with a 4’ downrod is 150 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
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.
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 oor with a large crosshatched circle, similar to the gure to the left, to alert personnel of the overhead fan
locations.
BEFORE YOU BEGIN SAFETY & PRECAUTIONS
!
CRUSH HAZARD

6
BEFORE YOU BEGIN 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.
A large fan, 20 to 24 foot in diameter, performs best at 20 to 30 feet above the oor, but acceptable performance has been demonstrated
as low as 10 feet and as high as 50 ft.
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 re sprinklers are present, the fan should not interfere with their operation.
•Fans should be located at least 3 feet below a sprinkler deector.
• Fans should be centered between 4 adjacent sprinklers.
•The Industrial Control Panel should be connected to a re relay system, which can stop the fans in the event a re 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 xture.
Air Discharge Locations
Fans should not be located directly beneath any vertical 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; however the discharge of the unit must be
located outside the swept area and at a distance of at least two times the diameter of the fan. For horizontal air discharge, the fan cannot
be placed in direct path at any distance.
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 only suitable for mounting in damp locations.
Other HVLS Fans
See the chart on the next page to determine proper spacing between adjacent fans.
