Notes:
• 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 and heating speed as needed.
• For most jobs, about 375 - 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.
• This chart is for information only. For satisfactory operation, external static pressure should not exceed value shown on the rating plate.
• 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 ESP at the CFM will be lower.
• Factory Motor Speed Setting: T1 = 1st Stage Ht, T2 = 2nd Stage Ht, T5 = Cooling.
• Temperature rise data is based on 2nd-stage heat. First-stage heat is 75% of rise indicated above.
