CAUTION & SAFETY

READ THE ENTIRE MANUAL BEFORE OPERATING THE FAN. Ensure that all safety practices and instructions are followed during the installation, operation and servicing of the fan. Failure to

apply these safety practices could result in death or serious injury. If you do not understand the instructions please call our Technical department for guidance.

The fan installation should follow the recommendations outlined in this manual. MacroAir is not responsible for any injury or damage to people or property as a result of not complying with the

recommendations outlined in this manual.

IMPROPER ELECTRICAL INSTALLATION CAN CAUSE DAMAGE TO THE FAN AND INTERFERE WITH OTHER ELECTRONIC EQUIPMENT. IN ADDITION TO STANDARD ELECTRICAL SAFETY

CONSIDERATIONS, PLEASE OBSERVE THE FOLLOWING:

• THE WIRING FROM THE CONTROL PANEL TO THE FAN MOTOR MUST BE MACROAIR-SUPPLIED SHEILDED CABLE.

• SEPARATE INCOMING POWER AND MOTOR CONTROL CABLES BY A MINIMUM OF (6) INCHES.

• RUN WIRING FOR EACH FAN SEPARATELY.

• DO NOT ATTEMPT TO CONTROL MULTIPLE FANS WITH ONE CONTROL PANEL.

• ALWAYS GROUND PROPERLY. CONNECT THE SUPPLIED CABLE GLANDS TO EACH END OF THE MOTOR CONTROL CABLE AND TIGHTEN THEM SECURELY AT BOTH THE FAN MOTOR

AND CONTROL PANEL ENDS. CONNECT THE GROUND BAR IN THE CONTROL PANEL TO GROUND AT THE MAIN BREAKER BOX.

• PLEASE REFER TO THE INSTALLATION INSTRUCTIONS FOR MORE INFORMATION.

All fan controls should only be installed by qualiﬁed technicians familiar with the requirements of the NEC and local codes. Refer to appropriate portions of this manual for other important

requirements. Failure to follow these guidelines will void the manufacturer’s warranty.

NOTICE:

All electrical controls are conﬁgured at the factory and are ready to use. No user adjustments are available. Follow the included wiring schematics and installation instructions when installing

this device to ensure proper operation. Do not make any changes to any part of the motor control panel without ﬁrst consulting MacroAir.

Installation is to be in accordance with the national electrical code, ANSI/NFPA 70-1999 and local codes.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Read and understand this manual before installing or operating

a fan unit. Installation, adjustment, repair, maintenance must be

performed by qualiﬁed personnel.

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. DO NOT

TOUCH.

Install all covers before applying power or starting and stopping

the unit.

DAMAGED EQUIPMENT

Do not 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.

MAINTENANCE AND SERVICE:

If the fan does not operate properly using the procedures in this manual, BE CERTAIN TO REMOVE ALL POWER TO THE

UNIT and contact our technical department for futher assistance.

Keep all body parts clear of moving part at all times.

All electrical troubleshooting and repair must be done by a qualiﬁed technician and meet all applicable codes.

CAUTION & SAFETY

Key Safety System Components

MacroAir fans are engineered with key safety features to prevent pieces of the fan from falling in the unlikely event of a catastrophic failure. Used together, these

systems and devices provide comprehensive protection of people, equipment and property. Follow the detailed instructions precisely when installing fans, including

the following:

Install safety cable on EVERY fan. Install guy wires on every fan, unless otherwise speciﬁed. Properly installing the guy wires will keep the fan stable in case of

earthquake or in “outdoor” installations where high wind conditions may occur. The safety cable, if installed per MacroAir speciﬁcations, will prevent the fan from

falling in the unlikely event that the mounting system should fail. A MacroAir fan should never be run without a properly installed safety cable, which is supplied with

every fan along with all required hardware. You must install a safety cable for the warranty to be in effect.

Install the complete set of extended blade safety links, which connect each blade to the adjacent blades and reinforce the area between the mounting holes. This is

an important precautionary measure which will help prevent a blade from falling should one break off at the hub for any reason.

Mark the Floor to Alert Personnel

When mounting a fan in an area where materials may be elevated into its path, MacroAir recommends marking or painting the ﬂoor with a large crosshatched circle

to alert personnel of the overhead location of fans.

Weight Considerations

We recommend that a building structure be capable of holding approximately twice the stated hanging weight of the fan. If there is some doubt of this, a professional

contractor or architect should perform a thorough evaluation of the building prior to purchasing the fans. MacroAir 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, that the building structure is sound and that the

installation complies with all federal, state, and local codes.

Torque

The maximum torque (twisting force) that must be handled by the mounting system, including the building structure, occurs at fan startup. For a 24 foot fan,

maximum potential starting torque is 300 Ft-Lbs. When standard electrical controls are installed, the fan will never begin to approach this maximum because the

standard variable-speed control system uses the soft-start technology. However, should the soft-start fail, or when a fan is installed as a single-speed model without

the variable speed control system (rare), full torque might be applied to the mounting system, so it is important that it be adequate to withstand 300 Ft-Lbs torque.

Check Federal, State, and Local Codes

Check all relevant codes to make sure that all product certiﬁcations, product listings, and building regulations are met. Code compliance is the responsibility of the

installer.

FAN PLACEMENT - GENERAL INFORMATION

Sprinkler Systems and Fan Placement

In any installation where ﬁre sprinklers are in place, do not interfere with their correct operation. Fans should be located no less than 3 feet

below a sprinkler, and placed central to each sprinkler quadrant. Our standard variable-speed control system can be connected to a ﬁre

suppression control system, which will emergency-stop fans in case of ﬁre. Prior to installing fans, review all codes applicable to sprinkler

systems and fans to ensure code compliance. Refer to the wiring diagrams packaged inside the control panel for proper installation. If further

advice is needed, you may contact our support staff. However, it is your sole responsibility to see that the installation is completed to code and

that it is correct.

Other Information on Placement and Spacing

If possible, avoid mounting fans directly below lights or skylights to avoid any strobe effect caused by moving blades. Note, a large fan, 20 – 24

feet in diameter, performs best at 20 to 30 feet above the ﬂoor, but acceptable performance has been demonstrated as low as 10 feet and as

high as 50 feet.

If the building has a mezzanine, fans should be mounted so a person can not reach a fan in any way from the upper level/deck. Make certain

that fans are positioned to that the blade tips are at least 3 feet away from any area where a person may be able to extend outward to reach

them.

WARNING: FANS ARE NOT MEANT TO BE OPERATED IN WINDY CONDITIONS.

The minimum distance of a fan to a wall or similar obstruction should be no less than 1.5 times the diameter of the fan.

The goal of this diagram is to determine the proper extension length to maintain a minimum blade clearance of 15% of the fan’s diameter. The extension

lengths above are minimum recommendations only, based solely on roof pitch and fan diameter. Other factors must be evaluated when determining extension

requirements. In addition, MacroAir strongly recommends that the fan blades must be a minimum of 10 feet (3.05 meters) above the ﬂoor. Contact our

technical department for assistance with fan placement and extension selection (technical support contact information can be found on page 36).
