NOTE:
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 horspower 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. Airflows over 1800 CFM require bottom return, two−side return, or bottom and side return. A minimum filter size of 20” x 25” is required.
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.
