PERFORMANCE DATA (cont)
ACCESSORY/FIOP STATIC PRESSURE (in. wg)* — 580F180-300
LEGEND
*The static pressure must be added to external static pressure. The sum and the evaporator entering-air cfm should then be
used in conjunction with the Fan Performance tables to determine blower rpm and watts.
FAN RPM AT MOTOR PULLEY SETTINGS*
*Approximate fan rpm shown.
†Indicates standard drive package.
**Indicates alternate drive package.
††Due to belt and pulley size, pulley cannot be set to this number of turns open.
EVAPORATOR-FAN MOTOR PERFORMANCE
LEGEND
*Extensive motor and electrical testing on these units ensures that the full horse-
power (brake kilowatt) range of the motors can be utilized with confidence. Using
your fan motors up to the horsepower (brake kilowatt) ratings shown in this table
will not result in nuisance tripping or premature motor failure. Unit warranty will
not be affected.
NOTE: All indoor-fan motors 5 hp and larger meet the minimum efficiency require-
ments as established by the Energy Policy Act of 1992 (EPACT) effective
October 24, 1997.
EVAPORATOR-FAN MOTOR EFFICIENCY
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.
