*Single phase/3 phase.
NOTES:
1. Convert bhp to watts using the following formula:
2. The EPACT (Energy Policy Act of 1992) regulates energy require-
ments 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. There-
fore, the indoor fan motors for Bryant 581C024-060 units are
exempt from these requirements.
ACCESSORY/FIOP STATIC PRESSURE* (in. wg) — 581C024-060
LEGEND *The static pressure must be added to external static pressure. The
sum and the evaporator entering-air cfm should be used in conjunction
with the Fan Performance tables to determine indoor blower rpm and
watts.
