Air Delivery−CFM Notes
*Actual external static pressure (ESP) can be determined by using the fan laws (CFM 2 proportional to ESP); such as, a system with 1180 CFM at 0.5
ESP would operate at cooling airflow of 1050 CFM at 0.4 ESP and low−heating airflow of 735 CFM at 0.19 ESP.
 Efficiency airflow are shown in parenthesis. Efficiency is selected when the low−heat rise adjustment switch (SW1−3) is OFF and the comfort/effi-
ciency switch (SW1−4) is OFF.
Ductwork must be sized for high−heating CFM within the operational range of ESP.
Operation within the blank areas of the chart is not recommended because high−heat operation will be above 1.0 ESP.
***All airflow on 110 size furnace are 5% less on side return only installations.
