● When charging with a refrigerant cylinder, use an
electronic scale for charging refrigerant. In this
case, if the volume of refrigerant in the cylinder
becomes less than 20% of the fully-charged

to change. Thus, do not use the refrigerant if the
amount in the charging cylinder is less than 20%.
Also, charge the minimum necessary amount to
the charging cylinder before using it to charge the
air conditioning unit.
