ARI* CAPACITY RATINGS — 580F180-300
LEGEND
*Air Conditioning and Refrigeration Institute.
NOTES:
1. Rated in accordance with ARI Standards 360 and 270.
2. ARI ratings are net values, reflecting the effects of circulating fan
heat.
3. 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.
4. All 580F180-300 units are in compliance with ASHRAE 90.1-
1999 Energy Standard for minimum SEER and EER require-
ments. Refer to state and local codes or visit the following website:
http://solstice.crest.org/efficiency/bcap
to determine if compliance
with this standard pertains to a given geographical area of the
United States.
HEATING CAPACITIES AND EFFICIENCIES — 580F180-300
*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.
