Refrigerant used in refrigeration circuit 2 of the appliance for
cooling. The global warming potential (GWP) of the refrigerant is
given in brackets.
Filling charge ll:
Filling weight of the refrigerant and corresponding size of the CO
2
equivalent in the second stage.
PS high pressure ll:
Maximum permissible working pressure on the high-pressure side
of the refrigeration circuit (compression, condensation)
PS low pressure II:
Maximum permissible working pressure on the low-pressure side
of the refrigeration circuit (expansion, evaporation)
