NOTE
: 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.
--- Indicates unstable operating conditions.
