  7. CHARGE AIR CONDITIONING SYSTEM WITH REFRIGERANT


    1. Perform vacuum purging using a vacuum pump or appropriate equipment.

    2. Charge the air conditioning system with refrigerant.

      Note


      • Do not turn the A/C switch on before charging the air conditioning system with refrigerant. Doing so may cause the compressor to work without refrigerant, resulting in overheating of the compressor.

      • The refrigerant amount should be checked by quantity (weight).

      Tech Tips

      Ensure that sufficient refrigerant is available to recharge the system when using a refrigerant recovery unit. Refrigerant recovery units are not always able to recover 100% of the refrigerant from an air conditioning system.

  8. WARM UP ENGINE


    1. Keep the A/C switch on for at least 2 minutes to warm up the compressor.

      Note

      To prevent damage to the compressor, be sure to warm up the compressor when turning the air conditioning on after removing and installing air conditioning system lines (including the compressor).

  9. INSPECT FOR REFRIGERANT LEAK


    1. After recharging the air conditioning system with refrigerant, check for refrigerant leaks using a halogen leak detector.

    2. Carry out the test under the following conditions:


      • Turn the engine switch off.

      • Measure the pressure to make sure that there is some refrigerant remaining in the air conditioning system.

        Pressure when the compressor is off: approx. 392 to 588 kPa (3.9 to 5.9 kgf/cm2, 57 to 85 psi)

      • Ensure good ventilation (the halogen leak detector may react to volatile gases which are not refrigerant, such as gasoline vapor and exhaust gas).

      • Repeat the inspection 2 or 3 times.

      How to check for refrigerant leaks in pipe joints:

      Note

      Gas leaking from a joint can be dissipated by even the slightest breeze. Move the halogen leak detector sensor 360° around each joint instead of keeping it in one spot when checking.

    7. Using a halogen leak detector, check for refrigerant leaks at the pipe joints shown in the illustration.

      Tech Tips


      • After the blower motor has stopped, leave the cooling unit for more than 15 minutes.

      • Disconnect the pressure sensor connector and leave it for approximately 20 minutes.

      • When checking for leaks, the presence of oily dirt at a joint can indicate a leak.

      Standard
      There are no refrigerant leaks from the joints.

      If refrigerant is leaking, disconnect the leaking joint and visually check for the cause, such as the presence of foreign matter.

      *a Halogen Leak Detector

      Bring the halogen leak detector sensor close to the drain cooler hose with the detector turned off, and then turn the detector on.

      Note

      Keep water away from the halogen leak detector to prevent malfunction.

      Tech Tips


      • After the blower motor has stopped, leave the cooling unit for more than 15 minutes.

      • When bringing the halogen leak detector sensor close to the drain cooler hose, make sure that the halogen leak detector does not react to volatile gases. If it is not possible to avoid interference from volatile gases, the vehicle should be lifted up to allow checking for leaks.

      Standard
      Refrigerant is not leaking from the drain cooler hose.

      If refrigerant is leaking, check for refrigerant leaks from the No. 1 cooler evaporator sub-assembly.
