Notes:
1.Cooling Performance and Heating 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. Units are suitable for operation to ±20% of nominal cfm. Certified in accordance with the Unitary Large Equipment certification program, which is based on ARI Standard
2.EER is rated at ARI conditions and in accordance with ASHRAE test procedures.
3.Integrated Part Load Value is based in accordance with ARI Standard 210/240 or 340. Units are rated at 80°F entering dry bulb, and 67°F entering wet bulb at ARI rated cfm.
4.Sound Rating shown is tested in accordance with ARI Standard 270 or 370.
5.Refrigerant charge is an approximate value. For a more precise value, see unit nameplate and service instructions.
6.Optional 2 inch pleated filter also available.
*Indicates both downflow and horizontal units.
