Low Heat Airflow
1. Nominal 350 CFM/ton cooling airflow is delivered with SW1 ---5 and SW2 ---2 set to OFF.
Set both SW1 ---5 and SW2 ---2 to ON for +7% airflow (nominal 370 CFM/ton).
Set SW1 ---5 to ON and SW2 ---2 to OFF for +15% airflow (nominal 400 CFM/ton).
Set SW2 ---2 to ON and SW1 ---5 to OFF for ---7% airflow (nominal 325 CFM/ton).
The above adjustments in airflow are subject to motor horsepower range/capacity.
2. Maximum cooling airflow is achieved when switches SW2 ---6, SW2 ---7, SW2 ---8 and SW1 ---5 are set to ON, and SW2 ---2 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 of 1880 CFM or less on 21" and 24.5" casing size furnaces are 5% less on side return only installations.
6. Return air above 1800 CFM on 24.5" casing requires two sides, one side and bottom, or bottom only to allow sufficient airflow to the furnace.
7. For upflow applications, air entering from one side into both the side of the furnace and a return air base counts as a side and bottom return.
8. Airflow not stable at this ESP .
