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.
