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.

• 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.

BEFORE YOU BEGIN

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 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.

Mark the Floor to Alert Personnel

When mounting a fan in an area where materials could be elevated and contact the rotating fan blades, be sure to
mark or rope off the area of install.

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 fan hanging weight and torque is as follows:

MAXIMUM HANGING WEIGHT TORQUE

24’ Titan 212 lbs. 75 ft lbs.

24’ ECO 150 lbs. 75 ft lbs.

14’ XP 135 lbs. 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.

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).

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.

MAINTENANCE

ELECTRIC SHOCK HAZARD

TO PREVENT SERIOUS INJURY OR DEATH:

• BEFORE performing maintenance or service, ALWAYS disconnect the power by turning off the circuit breaker or

breakers to the fan locations and conrm Lockout/Tagout procedures are in place.

• If you cannot lock the circuit breakers in the off position, securely fasten a prominent warning device, such as a
tag, to the electrical panel.

• Do not remove covers while power is on.

Blade Cleaning

Depending on the commercial application, dust or other particulates can build up on the fan blades over time. At least every 12
months, a maintenance person or skilled trade professional, who has experience using a lift, should clean the blades using a rag or
sponge and hot water or regular cleaning solutions. DO NOT use chlorine or any chemicals containing chlorine or the blades may be
damaged.

Retention System Check

Each fan is installed with a retention system. Every 12 months, check that the retention cable is properly attached to the building struc­ture. Inspect the visible portions of the retention cable for damage, including fraying.

The retention cable is an important part of the safety system and protects users in the unlikely event of a catastrophic situation. It is
critical for fan owners to ensure that it is intact and properly secured.

Replacement Parts

Please call 1-844-593-FANS (3267) for replacement parts.

Service

If the fan does not operate properly using the procedures in this manual, follow Lock-Out, Tag-Out procedures for your facility and
lockout all power to the unit and contact our Technical Department for further assistance at 1-844-593-FANS (3267).

REFERENCE

TROUBLESHOOTING

Symptom Possible Solution

• Verify that the fan’s circuit breaker has power and that it is on.

• Verify that the VFD’s receptacle has power and that the VFD is plugged in.

FAN WILL NOT START

• Check for secured plug connections. Each connection should be checked to ensure
they are fully engaged.

• Inspect for loose wiring connections. Each termination should be checked to be

sure they are rmly tightened.

IF THE ABOVE IS
VERIFIED AS WITHIN
SPECIFICATION

MOTOR IS PULLING
EXESSIVELY HIGH AMPS

FAN IS “SWINGING” AS IT
RUNS

A FAN BLADE APPEARS TO
BE ‘SAGGING’

• Cycle the power to the VFD by ipping the circuit breaker off for a minimum of
three minutes. Flip the circuit breaker back on and check the fan’s operation.

• Make sure the motor voltage is a match for the supply voltage.

• Make sure that correctly sized fan blades have been installed.

• Check for correct fan blade installation. Be sure that all blades are the same size
and that all blades have been properly installed and tightened.

• Ensure all guy wires are tensioned properly and that the downrod is plumb.

• Check for improper incoming air discharge. Make sure that no discharge is
blowing directly on the fan.

• Make sure that the ‘sagging’ blade has been properly tightened.
