Caution & Safety
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
Ensure the fixing means for attachment to the ceiling such as hooks or other devices shall be
fixed with a sufficient strength to withstand 4 times the weight of the ceiling fan. The maximum
hanging weight for the Model 370 is 79 lbs [36 kg] including the weight of an additional drop
length. If there is any uncertainty in the strength of the building structure, 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) during normal operation that must be handled by the
mounting system, including the building structure. For a Model 370, the maximum potential
torque is 20 ft-lbs [27 N-m].
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.
