Automotive Air Conditioning Refrigerant Oil Analyzer, Car A/C System Compressor Oil Filter Test Tool,Refrigerant Oil Filter Tools

DescriptionOil Change Procedure1. Connect the filter, blue and red hoses, and quick-connect couplers.2. Connect the high- and low-pressure quick-connect couplers to the high and low-pressure refrigerant filling ports on the vehicle, respectively.3. Close the blue low-pressure quick-connect coupler and open the red high-pressure quick-connect coupler. This will cause the refrigerant oil in the low-pressure direction to flow to the high-pressure direction and into the container.4. When the refrigerant oil has reached a certain volume in the glass bottle, close the high-pressure valve. You can now remove the refrigerant oil and add new refrigerant oil.5. Open the high- and low-pressure valves to allow the new refrigerant oil to circulate.How to Filter Impurities1. Connect the filter to the blue and red hoses and quick-connect couplers.2. Connect the high- and low-pressure quick-connect couplers to the high and low-pressure refrigerant filling ports on the vehicle, respectively.3. Open the high- and low-pressure valves (the high-pressure valve should not be fully opened; the ball valve should be opened to about 1/4, and the low-pressure valve should be fully opened).4. Filter impurities by circulating the high- and low-pressure valves.5. Start the vehicle, turn on the air conditioner, and begin filtering and cleaning impurities.Includes:1 pc/set of automotive air conditioner refrigerant oil filter tools.
