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 21.

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 108 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.

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 31). 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.

This method is recommended for Glulams or wood beams 6” or wider. For narrower attachment points please refer to the Unistrut mounting method to span across two or more beams to increase the structural integrity.

1.3.1: Place the mount against the bottom of the beam and position the holes so that they are the furthest from the edge as possible. Keep in mind there are breakouts for wire and safety cable around the upper edge of the Rapid Mount Commercial. Determine where you want to route the power, remote, and safety cable and orientate the mount appropriately. It is ideal to route the safety cable on the opposite side of the power wire.

1.3.2: Mark each hole location and use a 3/16” drill bit to drill a pilot hole for each lag. The pilot hole depth must be as deep or deeper than the length of the lag bolts. Once the pilot holes are drilled, remove the breakouts to be used for power, remote, and safety cable.

Maintenance Information

Guy Wire Check (if applicable): Checking a MacroAir fan’s Guy wires for tension and inspecting for frayed sections could mitigate a problem before it occurs. Fan owners should conﬁrm that the Guy wires are not wrapped around any sharp edges. MacroAir recommends attaching Guy wires to the building with eye bolts or eye lags. If they are not already installed with eye bolts or lags, we urge fan owners to install these in order to help keep the Guy wires from fraying. If Guy wires are installed with turnbuckles, jam nuts should periodically be checked to ensure tightness. If they are loose, the Guy wire cables may need to be re-tensioned.

Airfoil Cleaning: Depending on the type of commercial application the MacroAir fan is in, there can be quite a bit of dust or other particulates (including grease!) that cling to the fan’s airfoils. While this may not affect fan performance, we recommend fan owners keep airfoils clean by having a maintenance person or skilled trade professional – who has experience using a lift – wipe the fan airfoils with a rag or sponge using hot water or regular cleaning solutions. Please do not use chlorine or any chemicals containing chlorine.

Safety Cable Check: Each MacroAir fan comes with a safety cable. Depending on the fan model, the safety cable either wraps around the building structure and the fan frame, or comes out of the top of the fan and wraps around the building structure. The safety cable is an important part of the safety system and acts as a last resort should an earthquake, collision, or similar catastrophic event occur. As such, it’s vital for fan owners to ensure that it is intact and properly secured.

Reverse Operation: The beauty of MacroAir HVLS fans is that they are built to run in forward and reverse mode, however changing the direction of your fan can put initial stress on the fan if it has not been properly checked. It is a good idea to make sure the safety cables and all bolts and nuts are tight. Cleaning the fan before switching directions will prevent dust and other particles from falling off the fan airfoils that are now turning in the opposite direction.

What does the 50,000 hour warranty cover?

This warranty covers any part or component of the AirVolution-D shipped by MacroAir that is found to contain a manufacturing defect. MacroAir will repair or replace such part, component, or the entire fan free of charge.

How Long Does the Coverage Last?

This warranty covers the entire AirVolution-D fan and all its component parts for 50,000 hours of running time.

Do I Need to Pay Shipping, Removal and Re-Installation Costs?

You do NOT need to pay shipping, removal and installation costs if your AirVolution-D needs to be repaired or replaced due to a manufacturing defect within three years of the original purchase, and you will be reimbursed for those costs, upon approval of such costs by MacroAir. After three years, this warranty is still in full effect for the remainder of the 50,000 hours, but it just does not cover your cost to ship the fan to MacroAir, or removal or re-installation of the fan.

What is NOT covered under this warranty?

This warranty will not cover repairs or replacements caused by installation, operation or storage of the fan that is outside the speciﬁcations and limitations contained in the AirVolution-D installation and operation instructions.
