Refrigerant Charging

Cylinder with a siphon
Cylin-

Cylinder color R32 is light blue.
1. Reasons
R32 is a single refrigerant with a boiling point of -52°C (-62°F) and can be handled in a similar manner as with other single
refrigerants, such as R22.
2. Notes
When using a cylinder with a siphon, refrigerant is charged in the liquid state without the need for turning it upside down. Check
the type of the cylinder on the label before use.
If the refrigerant leaks out, it may be replenished. The entire refrigerant does not need to be replaced. (Charge refrigerant in
the liquid state.)
Refer to the following page(s).[8-12 Measures for Refrigerant Leakage]
