1.

Nominal 350 CFM/ton cooling airflow is delivered with SW1-5 and SW4-2 set to OFF.
Set both SW1-5 and SW4-3 to ON for +7% airflow (nominal 370 CFM/ton).
Set SW1-5 to ON and SW4-3 to OFF for +15% airflow (nominal 400 CFM/ton).
Set SW4-3 to ON and SW1-5 to OFF for -7% airflow (nominal 325 CFM/ton).

2.

Maximum cooling airflow is achieved when switches SW3-1, SW3-2, SW3-3 and SW1-5 are set to ON, and SW4-3 is set to OFF.

3.

All heating CFM's are when low heat rise adjustment switch (SW1-3) and comfort/efficiency adjustment switch (SW1-4) are both set to
OFF

4.

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.

5.

All airflows on 21" casing size furnaces are 5% less on side return only installations.

6.

Side returns for 24.5" casing sizes require two sides, or side and bottom, to allow sufficient airflow at the return of the furnace.
