Automotive Air Conditioning Compressor Oil Filter Air Conditioning Refrigerant Oil Analyzer Car Refrigeration Oil Purifier. Name: Automotive Air Conditioning Compressor Oil Filter. Applicable Models: All R134a Air Conditioning Systems. Oil Change Operation Method. Connect the filter and blue and red hoses and quick connectors. Connect the high and low pressure quick connectors to the high and low pressure fluorine filling ports on the vehicle respectively. Close the blue low pressure quick connector and open the red high pressure quick connector. At this time, the refrigerant oil in the low pressure direction will go to the high pressure direction and enter the container. When the refrigerant oil enters the glass bottle and reaches a certain capacity, close the high pressure valve. At this time, you can take out the refrigerant oil and add new refrigerant oil. Open the high and low pressure valve switches to allow the new refrigerant oil to enter the pipeline for circulation. How to Filter Impurities. Connect the filter to the blue and red hoses and quick connectors. Connect the high and low pressure quick connectors to the high and low pressure fluorine inlets on the car respectively. Open the high and low pressure valves (the high pressure valve cannot be fully opened, the ball valve is opened to about 1/4, and the low pressure valve is fully opened). Use high pressure to low pressure circulation to filter impurities. Start the car and turn on the air conditioner to start filtering and cleaning impurities.
