Trane’s 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.
