* Actual external static pressure (ESP) can be determined by using the fan laws (CFM
would operate at high ---heating airflow of 1500 CFM at 0.37 ESP and low---heating airflow of 705 CFM at 0.08 ESP .
{ Low heat CFM when low---heat rise adjustment switch (SW1 ---3) and comfort/efficiency adjustment switch (SW1 ---4) on control center are 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 .
