{
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 to350 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 filter rack installation instructions for correct filter size and quantity.

Based on altitudes from sea level to 2000 ft (610 m) above sea level. In th e U.S.A. for altitudes above 2000 ft (610 m), reduce input rating 4 percent for each
additional 1000 ft (305 m) above sea level. In Canada, from 2000 ft (610 m) above sea level to 4500 ft (1372 m) above sea level, derate the unit 10 percent.
