Necessary preliminary tasks
Before actually testing for leaks, check the entire refrigerant circuit using the UV leak detection lamp to ensure that no UV additive is already in the area of the refrigerant circuit.
If already illuminated areas are found, carefully clean the area in question with the cleaning agent contained in the case.
On initial use:
Connect hand pump (1) to additive cartridge (2) and hose piece (3).
On initial use:
Attach vent valve (1) to quick-release coupling (2).
Turn handle (3) on hand pump to advance the plunger until a small amount of UV additive emerges. This vents the hose system.
Attach quick-release coupling (1) to low-pressure connection (2) of air conditioning system.
Turn handle on hand pump (3) until the required amount of UV additive is added.
The quantity of UV additive to be added is dependent on the AMOUNT OF REFRIGERANT IN THE REFRIGERANT CIRCUIT :
- Air conditioning systems with refrigerant filling up to 900 g: one graduation mark (4) on additive cartridge
- Air conditioning systems with refrigerant filling in excess of 900 g: two graduation marks (4) on additive cartridge
Further tasks:
- Start engine
- Run air conditioning system at highest setting for 5 - 10 minutes in order to ensure adequate distribution of dye in the system
- Turn off engine.
- Check all air conditioning system components for possible leaks
- Possible leaks show up in luminous green
Complete accompanying information label (1) with the relevant data and attach in an easily visible position next to the filling capacity information label (2).
