**ARI* CAPACITY RATINGS — 581C024-060
LEGEND
*Air-Conditioning & Refrigeration Institute.
**ARI does not require EER ratings for unit with capacity below 65,000 Btuh. For
these units, the EER rating at ARI standard conditions is provided for informa-
tion only.
NOTES:
1. Rated in accordance with ARI Standard 210-94 or 360-93.
2. Ratings are net values, reflecting the effects of circulating fan heat.
3. 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.
4. All 581C024-060 units are in compliance with ASHRAE 90.1 2001, 2004
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.
