Use a certified A/C service center to carry out recovery, evacuation and charging of the refrigerant system. If an A/C service center is not available, refrigerant system recovery, evacuation and charging may be accomplished using a separate recovery station, vacuum pump, charging meter and manifold gauge set.
Leaks in refrigerant system service equipment, hoses or gauges can cause a leak that may be misinterpreted as a problem with the vehicle's refrigerant system. It is necessary to leak-test all refrigerant system service equipment, hoses and gauges on a weekly basis to verify that no leaks are present.
- Lubricate the refrigerant system with the correct amount of clean PAG oil.
- Connect an R-134a A/C service center to the low-side and high-side service gauge port valves following the operating instructions provided by the equipment manufacturer.
- Set the refrigerant charge amount, and charge the refrigerant system following the instructions provided by the equipment manufacturer.
