† Tested in accordance with ANSI/ASHRAE Standard 37-1988
‡ Airflow shown is for bottom only return-air (blower speed factory set). For
air delivery other than stated, refer to Dry Coil Air Delivery table.
†† Required filter sizes shown are based on the larger of the ARI (Air
Conditioning & Refrigeration Institute) rated cooling airflow or the heating
airflow velocity of 300 ft/min for throwaway type or 450 ft/min for high-
capacity type.
