LEGEND
FLA — Full Load Amps
HACR — Heating, Air Conditioning, and Refrigeration
LRA — Locked Rotor Amps
MCA — Minimum Circuit Amps
MOCP — Maximum Overcurrent Protection Amps (Fuse or HACR
Circuit Breaker)
RLA — Rated Load Amps
*Permissible limits of the voltage range at which units will operate
satisfactorily.
†One fan is 1.1 amps, and the other is 0.5 amp.
**Two fans, each operating at 1.3 amps.
††MCA and MOCP are for both indoor and outdoor units (system) and
are listed in the outdoor unit tables.
\Separate heater and unit circuits required.
NOTE: Two MCA, MOCP, and minimum wire size values are shown for
units with separate unit and heater circuits. The first value applies to the
unit circuit; the second applies to the heater circuit.
