Fluorescent Dye Leak Detection

WARNING: Eye protection glasses supplied with the ultraviolet (UV) lamp should be used to protect eyesight from harm.
NOTE:
The air conditioning (A/C) system has an R-134a leak trace dye wafer incorporated into the desiccant bag. The exact location of leaks can be pinpointed by the bright yellow/green glow of the tracer dye. Since more than one leak may exist, always inspect each component. If it is necessary to add dye (due to a severe leakage for example) use proprietary tracer dye injection equipment.
Check for leaks using ultraviolet (UV) lamp.
2 Check all components, fittings and lines of the A/C system.
3 Carry out the repair. For additional information, refer to.
4 After the leak is repaired, remove any traces of leak trace dye with a general purpose oil solvent.
5 Check the A/C system for correct operation.
6 Verify the repair by operating the system for a short time and inspecting with the (UV) lamp.
