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. Install guy wires on every fan, unless otherwise specified. Properly installing the guy wires will keep the fan stable in case of
earthquake or in “outdoor” installations where high wind conditions may occur. 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.
Install the complete set of extended blade safety links, which connect each blade to the adjacent blades and reinforce the area between the mounting holes. This is
an important precautionary measure which will help prevent a blade from falling should one break off at the hub for any reason.
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. If there is some doubt of this, a professional
contractor or architect 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, occurs at fan startup. For a 24 foot fan,
maximum potential starting torque is 300 Ft-Lbs. When standard electrical controls are installed, the fan will never begin to approach this maximum because the
standard variable-speed control system uses the soft-start technology. However, should the soft-start fail, or when a fan is installed as a single-speed model without
the variable speed control system (rare), full torque might be applied to the mounting system, so it is important that it be adequate to withstand 300 Ft-Lbs torque.
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.
