CFM in chart is without filter(s). Filters do not ship with this furnace, but must be provided by the installer.
•
All furnaces ship as hig-speed cooling. Installer must adjust blower cooling 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 values shown on the rating plate. The shaded area
indicates ranges in excess of maximum static pressure allowed when heating.
•
The dashed (---) areas indicate a temperature rise not recommended for this model.
•
At higher altitudes, a properly de-rated unit will have approximately the same temperature rise at a particular CFM, while ESP at the CFM will be lower.
