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.
