Install the injector between the low-side quick disconnect and the vehicle low-pressure service gauge port valve.
Open all quick disconnect valves and charge the refrigerant system. For additional information, refer to AIR CONDITIONING (A/C) SYSTEM EVACUATION AND CHARGING .
When system charging is complete, recover the refrigerant from the dye injector.

Remove the dye injector from the low-side quick disconnect valve.
