*Size 048 evaporator fan is equipped with a 460-v or integrated control motor (ICM). Size 060 evaporator fan is equipped with an ICM only. The ICM provides variable speed.

²Based on an altitude of 0-2000 feet.

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