Precautions for adding refrigerant
• Use a scale having a precision with at least 10 g
per index line when adding the refrigerant.
Do not use a bathroom scale or similar instrument.
• Use liquid refrigerant when refilling the refrigerant.
Since the refrigerant is in liquid form, it can fill quickly.
Therefore, perform the filling operation
carefully and insert the refrigerant gradually.
