Factory supplied motors, in commercial equipment, are
definite purpose motors, specifically designed and tested to
operate reliably and continuously at all cataloged conditions.
Using the full horsepower range of our fan motors as shown in
our tabular data will not result in nuisance tripping or
premature motor failure. Our product's warranty will not be
affected.
