NOTES:
1 Extensive motor and efactrical testing ensures that the motors can be uNized with con-
fidence up to the maximum applied bhp, watts, and amps. Using the fan motor up to
the maximum ratings shown wi}l not result in nuisance tripping or premature motor fail-
ure. Unit warranty will not be affected
2 All indoor-fan motors 5 hp and larger meet the minimum efficiency requirements as
established by the Energy Policy Act of 1892 (EPACT) effective October 24, 1997.
3. Convert bhp to watts using the following formula:
watts = bhp (746)
motor efficiency
