1. A filter is required for each return-air inlet. Airflow performance included 3/4-in. (19 mm) washable filter media such as contained in factory-authorized

accessory filter rack. To determine airflow performance without this filter, assume an additional 0.1 In. W.C. available external static pressure.

2. Adjust the blower speed tabs as necessary for the proper air temperature rise for each installation.

3. Highlighted areas indicate airflow range is beyond the range allowed for heating.  

THESE AIRFLOW RANGES MAY ONLY BE USED FOR COOLING.

4. -- Indicates unstable operating conditions.
