• This chart is for information only. For satisfactory operation, external static pressure should not exceed value show n on the rating plate.
• A properly derated unit w ill have approximately the same temperature rise at a particular CFM, w hile ESP at the CFM w ill be low er.
• Temperature rise data is based on 2nd-stage heat. First-stage heat is 75% of rise indicated above.
• CFM in chart is w ithout filter(s). Filters do not ship w ith this furnace, but must be provided by the installer. If the furnace requires tw o
• All furnaces ship as high-speed cooling and medium-speed heating. Installer must adjust blow er cooling and heating speed as needed.
• For most jobs, about 375 - 400 CFM per ton w hen cooling is desirable.
• INSTA LLA TION IS TO BE A DJUSTED TO OBTA IN TEMPERA TURE RISE WITHIN THE RANGE SPECIFIED ON THE RATING PLA TE.
