*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. 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.
