AIR DELIVERY—CFM (With Filters)*
* A filter is required for each return-air supply. Airflow shown is with factory supplied 1-in. washable filter(s). An airflow reduction of up to 7% may occur when
using the factory specified 4-5/16-inch wide, high-efficiency media filter. For best furnace efficiency when using the 4-5/16-inch wide media filter, adjust the
blower speed tap to near the mid-point of the rise range.
— Indicates unstable operating conditions.
