* Default & Recommended

1.
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.
2.
All furnaces ship as high speed cooling and medium-speed heating. Installer
must adjust blower cooling & heating speed as needed.
3.
For most jobs, about 400 CFM per ton when cooling is desirable.
4.
INSTALLATION IS TO BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE
RANGE SPECIFIED ON THE RATING PLATE.
5.
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.
6.
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.
