PRECAUTIONS HA-5 < PRECAUTION > C D E F G H J K L M A B HA N O P • For your safety and the customer's satisfaction, read and follow all manufacturer's operating instructions and precautions prior to performing work. • A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal should only be repaired after confirming the leak with an electronic refrigerant leak detector (J-41995). • Always remove any dye from the leak area after repairs are complete to avoid a misdiagnosis during a future service. • Do not allow dye to come into contact with painted body panels or interior components. If dye is spilled, clean immediately with the approved dye cleaner. 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 systems or CFC-12 (R-12) leak detection dye in HFC-134a (R-134a) A/C systems or A/C system damage may result. • The fluorescent properties of the dye will remain for over three (3) years unless a compressor failure occurs. A/C Identification Label INFOID:0000000006163092 Vehicles with factory installed fluorescent dye have this identification label on the underside of hood. Precaution for Refrigerant Connection INFOID:0000000006163093 A new type refrigerant connection has been introduced to all refrigerant lines except the following locations. • Expansion valve to cooling unit • Evaporator pipes to evaporator (inside cooling unit) • Refrigerant pressure sensor FEATURES OF NEW TYPE REFRIGERANT CONNECTION • The O-ring has been relocated. It has also been provided with a groove for proper installation. This reduces the possibility of the O-ring being caught in, or damaged by, the mating part. The sealing direction of the O- ring is now set vertically in relation to the contacting surface of the mating part to improve sealing character- istics. • The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby facili- tating piping connections.
