Leak Detection System VAS 6196

Or







Leak detection system VAS 6201

NOTE: Minor leaks can be made visible e.g. using fluorescent substance leak detection additive VAS 6196/1.

Leak Detection:
- If the refrigerant circuit is completely empty, charge with about 100 g of refrigerant.

NOTE: If leak detection additive was added to the refrigerant circuit, clean the area carefully with a cleaning solution. That way the residue will not be detected as a leak later.

- Add leak detection additive VAS 6196/1 to the refrigerant circuit.
- Start the engine and let it run at 1500 RPM. Switch the A/C system on so the leak detection additive is distributed through the refrigerant circuit.

NOTE: The A/C system must run for a minimum of 60 minutes so the additive distributes itself through the entire refrigerant circuit (the compressor must be running). Depending on the size and location of the leak, it may take several days before it is detected.

- Check the refrigerant circuit with the UV lamp.

NOTE: The leak detection additive can remain in the refrigerant circuit.
