AIR CONDITIONING SYSTEM PRECAUTION


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

  2. ALWAYS WEAR EYE PROTECTION

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

    A000QLT

    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.

  4. NEVER HEAT CONTAINER OR EXPOSE THE CONTAINER TO AN OPEN FLAME

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

  6. 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.

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

    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.

  8. 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.

  9. DO NOT OPERATE COMPRESSOR WITH MOTOR ASSEMBLY WITH NO REFRIGERANT

    CAUTION:

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

  10. PRECAUTIONS TO BE OBSERVED WHILE SERVICING

    CAUTION:

    Always use electrical insulating 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-OIL11 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-OIL11 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 the compressor oil in the compressor and replace it with ND-OIL11 to increase the ND-OIL11 ratio amount.

    • Replace the main components (evaporator, condenser, and compressor) if a large amount of oil other than ND-OIL11 enters the system. Failing to do so may cause electrical insulation performance to remain low, causing a DTC to be output.

  11. GENERAL PRECAUTION


    1. While using the auxiliary battery during inspection, do not bring the positive (+) and negative (-) tester probes too close to each other as a short circuit may occur.

  12. CHECK MEMORY CALL FUNCTION


    1. Memory registration.

      Note

      Be sure to have all the transmitters prepared and available before performing registration.


      1. Lock the doors using a transmitter before performing registration.

      2. Sit in the driver seat while holding only the transmitter to be registered.

      3. Turn the power switch on (Ready) and turn on the air conditioning.

      4. Turn the power switch off.

        Tech Tips

        It is necessary to register each transmitter individually

    2. Check memory call function.


      1. With the identification code of the transmitter registered in memory, check that the air conditioning operation is restored to its previous state when the turn the power switch on (Ready).

        Tech Tips

        The operation state differs depending on the registered transmitter.
