The best method to correctly charge refrigerant is to
completely empty the refrigerant circuit using refrigerant
recovery equipment.
Then charge the exact quantity of refrigerant according to

Cleaning the coil

If necessary, proceed as follows for
more careful cleaning of the coil:
Switch the mains supply OFF.
