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