Not es:
• Temperature rise data is based on 2nd-stage heat. First-stage heat is 75% of rise indicat ed above.
• 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 t wo
• 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 TEM PERATURE RISE W ITHIN THE RANGE SPECIFIED ON THE RATING PLATE.
• This chart is for information only. For satisfactory operation, external static pressure sho uld not exceed value shown on the rating plate.
• A properly derated unit w ill have approximately the same temperature rise at a part icular CFM, while ESP at the CFM will be lower.
