AIRFLOW

CFM in chart is without filter(s). Filters do not ship with this furnace, but must

be provided by the installer. If the furnace requires two return filters, this

chart assumes both filters are installed.

All furnaces ship as high speed cooling and medium-speed heating. Installer

must adjust blower cooling & heating speed as needed.

For most jobs, about 400 CFM per ton when cooling is desirable.

INSTALLATION IS TO BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE

RANGE SPECIFIED ON THE RATING PLATE.

The chart is for information only. For satisfactory operation, external static

pressure must not exceed value shown on rating plate. The shaded area

indicates ranges in excess of maximum external static pressure allowed when

heating. The data for 0.6" w.c. to 0.8" w.c. is shown for air conditioning

purposes only.

At higher altitudes, a properly derated unit will have approximately the same

temperature rise at a particular CFM, while the ESP at that CFM will be lower.
