* Within ± 2°F
† Minimum airflow is set for electronic air cleaner: 060—500 CFM, 080—500 CFM, 100—700 CFM, 120—700 CFM
‡ Use only listed jumper position combinations.
** Maximum available ESP is 0.70 iwc for all furnace model sizes and operating modes, except maximum available ESP is 0.50 iwc for HI cool size airflow at
400 cfm per ton selection with the 080 size furnace.
NOTES:
1. A humidistat can be used to further reduce airflow when increased humidity is sensed. This feature reduces the selected airflow by 20%, but no lower than
280 CFM per ton.
2. Continuous-fan selections are 50%, 65%, or 100% of selected cooling airflow. 100% is not recommended for 2-speed air conditioning or heat pumps.†
3. See the following airflow curves for CFM versus ESP at 350 CFM per ton.
4. Airflow shown is with factory supplied 1-in. washable filter(s). An airflow reduction of up to 7% may occur when using the factory-specified 4 5/16-inch wide, high-effi-
ciency media filter. For best furnace efficiency when using the 4 5/16-inch wide media filter, adjust the blower speed tap to near the mid-point of the rise range.
