*Single phase/3 phase.
NOTES:
1. Convert bhp to watts using the following formula:
bhp (746)
watts =
motor efficiency
2. 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 require-
ments. Therefore, the indoor fan motors for Bryant 581B036-150 units
are exempt from these requirements.

evaporator entering-air cfm should be used in conjunction with the Fan Perfor-
mance tables to determine indoor blower rpm and watts.
