*Required filter sizes shown are based on the larger of the AHRI (Air Conditioning Heating 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. W.C.

{If using accessory filter rack refer to the filter rack installation instructions for correct filter size and quantity. } For 460 volt units, add 14 lb (6.4 kg) to the weight.
