Tables are based upon rated CFM (airflow) across the evaporator coil and should be found under section titled “Refrigerant Charge” on Page 24 in manual. If there is any doubt as to correct charge being in the system, the charge should be removed, system evacuated and recharged to serial plate instructions.
