*

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.
