HA-6 < PRECAUTION > PRECAUTIONS • Perform leakage test and make sure that there is no leakage from connections after connecting line. Disconnect that line and replace the O-ring when the refrigerant leaking point is found. Then tighten connections of seal seat to the specified torque. COMPRESSOR CAUTION: • Plug all openings to prevent moisture and foreign matter from entering. • Store it in the same way as it is when mounted on the car when the compressor is removed. • Follow “Maintenance of Oil Quantity in Compressor” exactly when replacing or repairing compres- sor. Refer to . • Keep friction surfaces between clutch and pulley clean. Wipe it off by using a clean waste cloth moistened with thinner if the surface is contaminated with oil. • Turn the compressor shaft by hand more than five turns in both directions after compressor service operation. This distributes oil equally inside the compressor. Let the engine idle and operate the compressor for one hour after the compressor is installed. • Apply voltage to the new one and check for normal operation after replacing the compressor magnet clutch. LEAK DETECTION DYE 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. • Always wear 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: J-41995). The fluorescent dye leak detector should be used in conjunction with an electrical leak detector (SST: J-41995) to pin-point refrigerant leakages. • 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 (SST: J-41995). • Always remove any remaining dye from the leakage area after repairs are completed to avoid a mis- diagnosis during a future service. • Do not 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 extended period of time cannot be removed. • Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.). • Do not use more than one refrigerant dye bottle [1/4 ounce (7.4 cc)] per A/C system. • Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Do not use HFC-134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system or CFC-12 (R-12) leak detection dye in HFC-134a (R-134a) A/C system, or A/C system damage may result. • The fluorescent properties of the dye remains for three or more years unless a compressor malfunc- tion occurs.
