WARNING:

  • Always use HFC-134a for A/C refrigerant. If CFC-12 is accidentally charged, compressor will be damaged due to insufficient lubrication.
  • Always observe and follow precautions described on refrigerant container. Incorrect handling may result in an explosion of refrigerant container, frostbite, or the loss of eyesight.
  • Do not breathe A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose, or throat.
  • Do not allow HFC-134a to be exposed to an open flame etc. because it generates poisonous gas when in contact with high-temperature objects. Keep workshop well ventilated.

  3. Check the airtightness of A/C system for 25 minutes or more. If pressure rises more than the specified level, charge A/C system with approximately 200 g (0.4 lb) refrigerant and check that there is no refrigerant leakage. Refer to HA "Leak Test".

    CAUTION: Check the airtightness for 15 minutes or more if the parts are replaced.
