NOTES:

1. CFM in chart is without filters(s). Filters do not ship with this furnace, but must be provided by the installer.

2. All furnaces ship as high speed cooling. Installer must adjust blower cooling 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.

6The dashed (---) areas indicate a temperature rise not recommended for this model.

7.The above chart is for U.S. furnaces installed at 0-2000 feet. 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.
