ARI* CAPACITY RATINGS — 581B036-150
LEGEND
*Air-Conditioning & Refrigeration Institute.
†Applies only to units with capacity of 65,000 Btuh or less.
**The IPLV is not applicable to single-compressor units.
NOTES:
1. Rated in accordance with ARI Standard 210/240 (036-120 units) or
360 (150 units) and 270 (036-150 units).
2. Ratings are net values, reflecting the effects of circulating fan heat.
Ratings are based on:
Cooling Standard: 80 F db, 67 wb indoor entering-air temperature
and 95 F db outdoor entering-air temperature.
IPLV Standard: 80 F db, 67 F wb indoor entering-air temperature
and 80 F db outdoor entering-air temperature.
3. All 581C024-060 and 581B036-150 units are in compliance with
ASHRAE 90.1-1999 Energy Standard for minimum SEER and 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.
4. All 581C024-060 and 581B036-120 units are Energy Star certified.
