Follow the manufacturer’s instructions and instruction leaflets/note the viscosity.
1. Distribution of the oil
There is refrigerant oil in every component of the air-conditioning system. The oil is removed with the replaced component during repairs. It is therefore essential to refill the appropriate quantity of oil. The graphic on the right shows the average distribution of the quantities of oil within the system.
2. Observe the quantity and specification of the oil
Before mounting a new compressor or when refilling refrigerant oil, always check the oil quantity and the viscosity in the vehicle manufacturer’s instructions.
3. Correct quantity of system oil in the compressor
As one and the same compressor can potentially be used for different vehicles or systems, it is essential that the oil filling quantity be checked/corrected before mounting the compressor. For this purpose, all the oil must be siphoned off and collected. The compressor must then be refilled with the entire oil quantity specified by the vehicle manufacturer (system oil quantity). To ensure that the oil is distributed equally, the compressor must be turned 10 times by hand before installation. This also corresponds to
the instructions from the compressor manufacturer Sanden;
specifications from the vehicle manufacturer
must be observed separately in each case.
