NOTES:
1. Extensive motor and electrical testing on the Carrier units has
ensured that the full horsepower range of the motor can be uti-
lized with confidence. Using your fan motors up to the horse-
power ratings shown in the Motor Limitations table will not
result in nuisance tripping or premature motor failure. Unit war-
ranty will not be affected.
2. All motors comply with Energy Policy Act (EPACT) Standards
effective October 24, 1997.
