1.Units are shipped without filter(s). CFM in chart is without filter(s).
2.All furnaces shipped with heating speed set at "B" and cooling speed set at "D". Installer should adjust blower speed as needed. The first task is to determine the proper aiflow for the cooling system.
3.For most cooling applications, about 400 CFM per ton is desirable.
4.The chart is for information only. For satisfactory operation, external static pressure not to exceed value shown on rating plate.
5.Do not operate above 0.5" w.c. ESP in heating mode. Operating between 0.5" w.c. and 0.8" w.c. is tabulated for cooling purposes only.
6.* Motor CFM minimum.
