Connect the filter, blue and red hoses, and quick-connect couplers.
Connect the high- and low-pressure quick-connect couplers to the high and low-pressure refrigerant filling ports on the vehicle, respectively.
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).
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.
Open the high- and low-pressure valves to allow the new refrigerant oil to circulate.Start the vehicle, turn on the air conditioner, and begin filtering and cleaning impurities.
