ARI* CAPACITY RATINGS — 581A210-300
LEGEND
*Air Conditioning and Refrigeration Institute.
†IPLV values are calculated based on control configuration T.CTL = 2
(2 Stage Y1).
**Size 300 unit is not listed with ARI, but is tested to ARI standards.
NOTES:
1. Rated in accordance with ARI Standards 360-93 and 270-95.
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 temperature 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 581A210-300 units are in compliance with ASHRAE 90.1 2001 Energy
Standard for minimum EER requirements. Refer to state and local codes or
visit the following website: http://bcap-energy.org to determine if compliance
with this standard pertains to a given geographical area of the United States.
