NOTES:
1.Cooling Performance is rated at 35.0 C (95 F) ambient, 26.7 C (80 F) entering dry bulb, 19.4 C (67 F) entering wet bulb. Heating Performance israted at 20.0 C (68 F) ambient, 8.3 C (47 F) entering dry bulb, 6.1 C (43 F) entering wet bulb. Gross capacity does not include the effect of fan motor heat. Net capacity includes the effect of fan motor heat. Units are suitable for operation to + 20 % of nominal airflow.
2.EER are rated at ARI conditions.
3.Outdoor Sound rating shown is tested in accordance with ARI Standard 270. For more information refer to Performance Data Table “Sound Power Level”.
4.Refrigerant charge is an approcimate value. For a more precise value, see unit nameplate and service literature.
