ARI* CAPACITY RATINGS — 579F180-300
LOW HEAT UNITS
HIGH HEAT UNITS
LEGEND
*Air Conditioning and Refrigeration Institute.
NOTES:
1. Rated in accordance with ARI Standards 360 and 270.
2. The 579F300 is beyond the scope of the ARI Certification
Program.
3. ARI ratings are net values, reflecting the effects of circulating fan
heat.
4. Ratings are based on:
Cooling Standard: 80 F db, 67 F wb indoor entering-air tempera-
ture and 95 F db air entering outdoor unit.
IPLV Standard: 80 F db, 67 F wb indoor entering-air temperature
and 80 F db outdoor entering-air temperature.
HEATING CAPACITIES AND EFFICIENCIES — 579F180-300
*All units are 2-stage heat.
NOTE: Minimum allowable temperature of mixed-air entering the heat exchanger during first-stage
heating is 45 F. There is no minimum mixed-air temperature limitation during second-stage heating.
For entering-air temperatures below 45 F both stages of heat must be energized together to minimize
condensation issues and ensure proper unit operation.
