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.
NOTE:
- Only connect the dye-injector to the Manifold Gauge Set or the charging/recovery station when dye is to be injected. The dye injector has a one-way check valve that will prevent system refrigerant recovery and evacuation.
Remove the dye injector from the low-side quick disconnect valve.
