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.

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.

A - 1/4 x 2” (Minimum Length) Wood Lags (4)
(not provided)
B - Rapid Mount Commercial
C - Glulam
D - Extension Attachment Point
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.

1.3.3: Place the mount against the bottom of the beam and drive the four lag bolts into the pilot
holes but do not drive them all the way in as there needs to be roughly 1/2” of gap between the
top of the mount and the bottom of the beam to run wire and cable.
1.3.4: Once the power wire, remote cable, and safety cable have been routed and are sitting in
their appropriate breakouts the lags can be tightened (refer to lag manufacturer for torque
specs). While tightening the lags it is recommended that you observe all wires and cables to
ensure they are not getting damaged between the mount and beam.
1.3.5: Tighten the locking set screws on the mount once the extension attachment point is level.
