EVAPORATOR-FAN MOTOR EFFICIENCY
*Single phase/three-phase.
NOTE: The EPACT (Energy Policy Act of 1992) regulates energy
requirements for specific types of indoor fan motors. Motors regulated
by EPACT include any general purpose, T-frame (three-digit, 143 and
larger), single-speed, foot mounted, polyphase, squirrel cage induction
motors of NEMA (National Electrical Manufacturers Association) design
A and B, manufactured for use in the United States. Ranging from 1 to
200 Hp, these continuous-duty motors operate on 230 and 460 volt,
60 Hz power. If a motor does not fit into these specifications, the motor
does not have to be replaced by an EPACT-compliant energy-efficient
motor. Variable-speed motors are exempt from EPACT compliance
requirements. Therefore, the indoor-fan motors for these units are
exempt from these requirements.
