REFRIGERANT LEVEL CHECK, DRAINING AND CHARGING
caution
  • When refrigerant is charged, use the special tools for the EV24AN5 compressor to fill up the refrigerant, because it is different from the normal compressor oil. (If the normal compressor oil is mixed, damage may be resulted in.)
  • For the compressor oil and installation oil for the piping O-ring, use the oil MA68EV or Ze-GLES RB68 dedicated for the A/C compressor EV24AN5. If an oil other then the MA68EV or Ze-GLES RB68 is used, even if it is only a small amount, the electric insulation is considerably deteriorated and a leakage may occur.
  • Never charge the refrigerant excessively, or the A/C system may be damaged.
  • Always keep away thermal ignition sources, electrical sparks or flame impact from the refrigerant. In the presence of flame, refrigerant forms a poisonous gas. Keep the area well ventilated.
  • Recover the refrigerant according to the specified procedure. Never release it into the atmosphere.
noteWhen you have evacuated the system before filling with refrigerant, "No. B103A: Refrigerant pressure sensor system (short to power supply)" and "No. B103B: Refrigerant pressure sensor system (open or short to ground) will be set. On completion, erase these diagnostic trouble codes.
Drain the refrigerant by using MOR405JH-type flon recovery equipment (part number: MZ204413), and fill by the specified amount.
