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 Air-Source Unitary Heat Pump Equipment certification
program, which is based on ARI Standard 210/240.
2. SEER is rated at ARI conditions and in accordance with DOE test procedures.
3. Outdoor Sound Rating shown is tested in accordance with ARI Standard 270. For more information refer to Table PD-25.
4. Refrigerant charge is an approximate value. For a more precise value, see unit nameplate and service instructions.
5. Optional 2 inch pleated filters are also available.
