*Based on altitude of 0-2000 feet.

²Required ®lter sizes shown are based on the larger of the ARI (Air Conditioning & Refrigeration Institute) rated cooling air¯ow or the heating air¯ow at a velocity of 300 ft/min for throwaway type or 450 ft/min for high-capacity type. Air ®lter pressure drop for non-standard ®lters must not exceed 0.08 in. wg.
