Refrigerant System Charging Using An R-134A Service Center
It is recommended to use an A/C service center to carry out discharging, evacuation and charging of the refrigerant system. If an A/C service center is not available, refrigerant system discharging, evacuation and charging may be accomplished using a separate discharging 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. Refer to the under hood specification label or the refrigerant system charging service center for instructions.
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.
