The type label for refrigerant and filling capacities is
located on the lock carrier cover.
1 - Refrigerant identification, such as R134a
2 - Refrigerant capacity

Physical Principles
The four known states of water also apply to air
conditioning system refrigerants.
1 - Gaseous (invisible)
2 - Vapor
3 - Liquid
4 - Solid
When water is heated in a container (heat absorption), water
vapor can be seen to rise. If
Note
Cleaning the refrigerant circuit means flushing it with
refrigerant R134a. Refer to
→ Chapter "Refrigerant Circuit, Cleaning (Flushing), with
Refrigerant R134a" or blowing through with compressed
air and nitrogen. Refer to
