*
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.
{
Comfort airflow values are shown in parenthesis. Comfort airflow is selected when the low---heat rise adjustment switch (SW1---3) is OFF and
the comfort/efficiency switch (SW1---4) is ON.
}
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.
