NOTES:
1. Cooling Performance is rated at 95 F ambient, 80 F entering dry bulb, 67 F entering wet bulb. Gross capacity does not include the effect of fan motor heat. ARI capacity is net and
includes the effect of fan motor heat. Rated in accordance with ARI Standard 210/240 or 360
2. SEER are rated at ARI conditions and in accordance with DOE test procedures.
3. Heating Performance limit settings and rating data were established and approved under laboratory test conditions using American National Standards Institute standards. Ratings
shown are for elevations up to 2000 feet. For elevations above 2000 feet, ratings should be reduced at the rate of 4% for each 1000 feet above sea level.
4. AFUE and Steady State Efficiency is rated in accordance with DOE test procedures.
5. Sound Rating is rated in accordance with ARI Standard 270 or 370.
6. Refrigerant charge is an approximate value. For a more precise value, see unit nameplate and service instructions.
✲Indicates both downflow and horizontal units.
