Units are suitable for operation to±20%of nominal cfm. Rated in accordance with ARI Standard 210. 2. EER is rated at ARI conditions and in accordance with DOE test procedures. 3. Integrated Part Load Value is based on ARI Standard 210.Units are rated at 80°F ambient,80°F entering dry bulb,and 67°F entering wet bulb at ARI rated cfm. 4. 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 2,000 feet. For elevations above 2,000 feet,ratings should be reduced at the rate of 4%for each 1,000 feet above sea level. 5. AFUE and Steady State Efficiency are rated in accordance with DOE test procedures. 6. Sound is rated in accordance with ARI Standard 270. 7. Refrigerant charge is an approximate value.For a more precise value,see unit nameplate and service instructions.
