AIR CONDITIONING SYSTEM PRECAUTION


  1. PRECAUTION FOR DISCONNECTING CABLE FROM NEGATIVE AUXILIARY BATTERY TERMINAL

    Note

    When disconnecting the cable from the negative (-) auxiliary battery terminal, initialize the following systems after the cable is reconnected.

  2. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED AREA OR NEAR AN OPEN FLAME

  3. ALWAYS WEAR EYE PROTECTION

  4. BE CAREFUL NOT TO GET LIQUID REFRIGERANT IN YOUR EYES OR ON YOUR SKIN

    A01KRWC

    If liquid refrigerant gets in your eyes or on your skin:


    1. Wash the area with lots of cold water.

      CAUTION:

      Do not rub your eyes or skin.

    2. Apply clean petroleum jelly to the skin.

    3. Go immediately to a hospital or see a physician for professional treatment.

  5. NEVER HEAT CONTAINER OR EXPOSE CONTAINER TO AN OPEN FLAME

  6. BE CAREFUL NOT TO DROP CONTAINER OR APPLY PHYSICAL SHOCKS TO IT

  7. DO NOT OPERATE COMPRESSOR WITHOUT ENOUGH REFRIGERANT IN REFRIGERANT SYSTEM

    If there is not enough refrigerant in the air conditioning system, oil lubrication will be insufficient and the compressor may be damaged.

    Necessary care should be taken to avoid this.

  8. DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING

    *a Wrong
    *b Okay

    1. Open and close only the low pressure valve.

      If the high pressure valve is opened, refrigerant flows in the reverse direction causing the charging cylinder to rupture.

  9. BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH REFRIGERANT

    If the system is overcharged with refrigerant, it causes problems such as insufficient cooling, poor fuel economy, engine overheating, etc.

  10. DO NOT OPERATE COMPRESSOR WITH NO REFRIGERANT

    CAUTION:

    Doing so may damage the inside of the compressor because the compressor parts always move regardless of whether the air conditioning system is turned on or off.

  11. PRECAUTIONS TO BE OBSERVED WHILE SERVICING

    CAUTION:

    Always use insulated gloves and remove the service plug grip before beginning inspection, as inspection of the air conditioning system requires disconnecting high voltage connectors.

    Note


    • Only use ND-OIL 11 for the electric inverter compressor of the air conditioning system. Using other compressor oils may be dangerous, as they may conduct electricity.

    • Electrical insulation performance may decrease significantly if even a small amount of oil other than ND-OIL 11 is used (or enters) in the refrigeration cycle, causing a DTC to be output.

    • If other oil is accidentally used and a DTC is output, collect as much oil in the refrigerant cycle into the compressor as possible and replace it with ND-OIL 11 to increase the ND-OIL 11 ratio amount.

    • Replace the main components (evaporator, condenser, and compressor) if a large amount of oil other than ND-OIL 11 enters the system. Failing to do so may cause electrical insulation performance to remain low, causing a DTC to be output.

  12. SUPPLEMENTAL RESTRAINT SYSTEM (SRS)


    1. This vehicle is equipped with a Supplemental Restraint System (SRS) such as the driver, front passenger, side, and curtain shield airbags. Failure to carry out service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the precautionary notices.

  13. GENERAL PRECAUTION


    1. Do not bring the positive and negative tester probes too close to each other as a short circuit may occur.
