HA-20 < PRECAUTION > FLUORESCENT LEAK DETECTOR FLUORESCENT LEAK DETECTOR General Precautions INFOID:0000000003795892 CAUTION: • The A/C system contains a fluorescent leak detection dye used for locating refrigerant leakages. An ultraviolet (UV) lamp is required to illuminate the dye when inspecting for leakages. • Wear always fluorescence enhancing UV safety goggles to protect eyes and enhance the visibility of the fluorescent dye. • The fluorescent dye leak detector is not a replacement for an electrical leak detector (SST). The fluo- rescent dye leak detector should be used in conjunction with an electrical leak detector (SST) to pin- • Read and follow all manufacture’s operating instructions and precautions prior to performing the work for the purpose of safety and customer’s satisfaction. • A compressor shaft seal should not necessarily be repaired because of dye seepage. The compres- sor shaft seal should only be repaired after confirming the leakage with an electrical leak detector • Remove always any remaining dye from the leakage area after repairs are completed to avoid a mis- diagnosis during a future service. • Never allow dye to come into contact with painted body panels or interior components. Clean imme- diately with the approved dye cleaner if dye is spilled. Fluorescent dye left on a surface for an • Never spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.). HFC-134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system, or CFC-12 (R-12) leak detection • The fluorescent properties of the dye remains for three or more years unless a compressor malfunc- tion occurs. IDENTIFICATION NOTE: IDENTIFICATION LABEL FOR VEHICLE Vehicles with factory installed fluorescent dye have the identification label on the front side of hood. |
