Maximum Cooling Airflow

1. Nominal 350 CFM/ton cooling airflow is delivered with SW1-5 and SW4-2 set to OFF.
Set SW1-5 to ON for nominal 400 CFM/ton (+15% airflow).
Set SW4-3 to ON for nominal 325 CFM/ton (-7% airflow).
Set both SW1-5 and SW4-3 to ON for nominal 370 CFM/ton (+7% airflow).
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 E.S.P. Operation within the blank areas of the chart is not recommended
because high-heat operation will be above 1.0 E.S.P.
5. All airflows on 21" (533 mm) casing size furnaces are 5% less on side return only installations.
6. Side returns for 24.5" (622 mm) casing sizes require two sides, or side and bottom, to allow sufficient airflow at the return of the furnace.
(SW1-5 and SW4-3 set to OFF, except as indicated. See notes 1 and 2.)
