{
Required filter sizes shown are based on the larger of the ARI (Air Conditioning and Refrigeration Institute) rated cooling airflow or the heating airflow velocity of 300 ft/
minute for throwaway type or 450 ft/minute for high--capacity type. Air filter pressure drop for non--standard filters must not exceed 0.08 in. wc.
}
If using accessory filter rack refer to the filter rack installation instructions for correct filter sizes and quantity.
