NOTES:
1. CFM in chart is without filters. Filters do not ship with this
furnace, but must be provided by the installer. If the furnace
requires 2 return filters, this chart assumes both filters are
installed.
2. All furnaces ship as high-speed cooling and medium-speed
heating. Installer must adjust blower cooling and heating
speed as needed.
