The process of releasing refrigerant from a car air conditioner: 1. Install the manifold pressure gauge, connect one end of the green hose to the middle of the pressure gauge and the other end to the vacuum pump, then perform the vacuuming operation; 2. Install the refrigerant tank; 3. Fill refrigerant from the high-pressure side: Open the high-pressure side valve and add refrigerant when the engine is not running until the low-pressure gauge reaches approximately 0.98MPa, then close the valve after filling; 4. Check for leaks, use an electronic leak detector to check the system for leaks; 5. Fill refrigerant from the low-pressure side: After closing the high-pressure side valve, start the engine and run the air conditioner, open the manifold pressure gauge, and fill the specified amount of refrigerant; 6. When replacing the filling tank, close the valves on both the high and low-pressure sides, then open the purge valve to release air from the middle hose (green) and the manifold pressure gauge after replacement; 7. Check the refrigerant filling amount according to the pressure display of the manifold pressure gauge. When the refrigerant filling amount reaches the specified amount, the pressure of the manifold pressure gauge should also reach the specified value; 8. After the refrigerant filling amount meets the requirements, close the low-pressure side valve and turn off the engine.
