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