Notes:
Airflow tested with dry coil conditions, without air filters, at 230 V.
Applications above 0.8 in. W.C. external static pressure are not recommended.
Brushless DC high efficiency standard ECM blower motor used for all indoor blower assemblies.
Minimal variations in airflow performance data result from operating at 208 V. Data above may be used in those cases.
Heating applications tested at 0.50 in. W.C. external static pressure, and cooling applications tested at 0.30 in. W.C. external static pressure per standards.
