Using a digital psychrometer, measure the return air wet-bulb temperature at
the unit just before the coil. Also measure the outdoor dry-bulb temperature.
Use these temperatures to locate the target superheat on the charging table.
Do not attempt to charge the system if these conditions fall outside of this
charging table. ADD refrigerant to DECREASE total superheat. REMOVE
refrigerant to INCREASE total superheat. Always allow 10 to 15 minutes of
operation after any refrigerant or air flow change prior to determining the
final superheat.
