Filling With Fluorescent Tracing Agent and Refrigerant
Filling with fluorescent tracing agent and refrigerant
Regulations
Filling the climate control system with fluorescent tracing agent and leak tracing using a UV lamp
NOTE:
- Check whether there is a decal in the engine compartment indicating that the car is filled with fluorescent tracing agent.
- The coloring agent may discolor the car paint work. Therefore extreme caution must be taken when handling the tracing agent.
- Carefully follow the manufacturers instructions when handling the UV lamp and the tracing agent.
The fluorescent tracing agent can be injected in the following cases:
- when it is not possible to localize the leak using an electronic leak tracer
- when replacing components
- for leak tracing where tracing agent has not previously been used in the car
- when replacing the compressor if tracing agent has previously been used in the car
- when a majority of the components are replaced and tracing agent has previously been used in the car.
NOTE: When replacing components for example, do not forget to compensate for the amount of compressor oil in the climate control system.
1. Valves closed
2. The cover for the injector/reservoir
3. Fluorescent tracing agent.
NOTE: After filling with the tracing agent, the decal supplied by the manufacturer or supplier must be applied at the point indicated.
Filling with fluorescent tracing agent
When replacing a component in the climate control system, the component (for example the drier) can be filled with tracing agent.
- Filling an empty climate control system with tracing agent when a leak cannot be localized
- Add fluorescent tracing agent to the refrigerant according to the manufacturers instructions for leak tracing.
- If the climate control system is filled
- Drain the refrigerant.
- Fill the climate control system with refrigerant and tracing agent according to the manufacturers instructions
- Leak trace.
- If the amount of refrigerant in the climate control unit cannot be determined
- Drain the climate control unit.
- Fill the climate control system with refrigerant and tracing agent according to the manufacturers instructions
- Leak trace.
Injecting tracing agent
NOTE: On newer filling/draining/vacuum pumping stations there is a reservoir for injecting oil. It can be used for filling with fluorescent tracing agent before filling with refrigerant and after vacuum pumping.
- Check that the valves on the draining/recycling station are closed when the vacuum pumping is completed after draining the refrigerant.
- Close the valves on both side of the injector as illustrated
- Unscrew the cover on the injector
- Pour in the tracing agent. One bottle in the reservoir
NOTE: Always inject exactly the right amount. Do not inject the tracing agent twice.
- Screw on the cover, ensuring that it is secure
- Begin filling with the refrigerant
- Open the valves on the injector
- Fill the refrigerant in the air conditioning (A/C) system with tracing agent.
