{Recommended filter sizes for field---installed air filter grilles mounted on the wall or ceiling of the conditioned structure. 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 fo r high---capacity type. Ai r fi lter pressure drop for non---standard filters must not exceed 0.08 IN. W.C.
