Notes:
• All furnaces ship as high speed for cooling. Installer must adjust blower speed as needed.
• For most jobs, about 400 CFM per ton when cooling is desirable.
• Operation is recommended below .5” w.c. ESP in heating mode. Operating CFM between .5” and .8” w.c. is tabulated for cooling purposes only.
