Refrigerant: Service and Repair

Capacities

- Operate the A/C system after filling the refrigerant circuit. Refer to=> [ Operating A/C System after Filling Refrigerant Circuit ] Operating A/C System after Filling Refrigerant Circuit

• Note the information regarding operating the A/C system after filling.

• Different refrigerant oil capacities are designated depending on the compressor type ("6 SEU 14", "7 SEU 16" or " 7 SEU 17").

• Compressor as replacement part has different oil fill capacities, therefore note the exact part number. The reason for the different oil capacities in the compressor lies in the design of the compressor itself, note these oil capacities. Too much oil in the circuit leads to higher pressures and reduces cooling performance of the system. Too little oil may lead to lubrication problems in the compressor.

• When charging the A/C system, always use maximum amount of refrigerant R134a, as some of the refrigerant remains in the hose of the refrigerant recovery, recycling and recharging unit.

• Refrigerant circuit may only be filled with approved refrigerant oils.

• Zexel / Valeo, Sanden and Denso compressors require different refrigerant oils.

• For the Refrigerant Oil (G 052 300 A2) that must be used with Denso compressors.

• Use only the specified oil from a sealed container and always reseal oil container immediately after use PAG oil absorbs moisture). Do not use oil if it is contaminated with moisture or if oil container has been left open.
