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 (Technical Support contact

information can be found on page 29).

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 the user and/or installer

not complying with the recommendations outlined in this manual.

All fan controls and incoming power 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 fan 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, or 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 further 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. 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. Refer to page 20.

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. The maximum hanging weight for the Model 370 is 115 lbs including

the weight of an additional extension. If there is some doubt of this, a professional structural

engineer 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. For a Model 370, the maximum potential torque is 20 ft-lbs.

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.

Windy Conditions

Fans should not be operated when wind is present. Fans should not be installed in applications

where it is frequently windy.

Rev. Date 111714

Fan Placement

Sprinkler Systems and Fan Placement

In any installation where ﬁre sprinklers are in place, fan should 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 AirBrain motor controller 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 NFPA 13).

Please call our Technical Department for guidance (Technical Support contact information can be

found on page 29). 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 airfoils. 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 so that the airfoil tips are at

least 3 feet away from any area where a person may be able to extend outward to reach them.

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, OSHA requirements state that the fan airfoils 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 29).
