Key Safety Systems
⚠
ATTENTION: Safety. 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 to people, equipment, and property.
⚠
WARNING: Safety Cable and Guy Wires. Install safety cable on EVERY fan. Install guy wires
on every fan using a UMH mount, unless otherwise specified. Properly installing the guy wires
will keep the fan stable in case of eart
hquake 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.
⚠
WARNING: Safety Cable. 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.
⚠
ATTENTION: 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.
Mounting Guidelines
⚠
WARNING: 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.
⚠
WARNING: Torque. The maximum torque (twisting force) that must be handled by the
mounting system, including the building structure, occurs at fan startup. For a 12-foot fan,
maximum potential starting torque is 20 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 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 20 Ft-Lbs. torque.
⚠
ATTENTION: 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.
⚠
WARNING: Welding. DO NOT attach the fan or fan mounting components to the building
structure by welding that component to the structure. DO NOT cement the fan to the structure.
