Distribution of the Oil In the Refrigerant Circuit

Total oil quantity 195 ± 15 cubic.cm

After suction Removal from the system, the following quantities remain in the following quantities remain in the
condenser 2 x 20 cubic.cm approx. 40 cubic.cm
evaporator approx. 30 cubic.cm
fluid tank
with lines approx. 30 cubic.cm
compressor approx. 50 cubic.cm
circulating oil quantity
in the refrigerant circuit approx. 60 cubic.cm


NOTE: In new vehicles, the amount of oil removed by suction is approx. 15.... 40 cubic.cm.
Oil removed by suction must be returned to the system.


Refrigerant oil removed from a previously run air-conditioning system may no longer be used (special-category waste).

After the refrigerant has been removed by suction and a component has been replaced, the oil quantity must be determined and topped up by the quantity remaining in the removed component.
