COMPRESSOR (for ZR Series Engine) INSTALLATION


  1. ADJUST AMOUNT OF COMPRESSOR OIL


    1. When replacing the compressor assembly with a new one:

      Drain the following amount of compressor oil from the new compressor to be installed to adjust the amount of compressor oil.

      Standard (Amount of oil to be drained)
      50 cc (1.7 fl.oz)

      Note


      • Since compressor oil remains in the pipes of the vehicle, if a new compressor is installed without removing some oil from the compressor, the oil amount becomes excessive. Excessive oil prevents heat exchange in the refrigerant cycle and causes refrigeration system failure.

      • Be sure to use ND-OIL 8 or equivalent for compressor oil.


      1. Discharge the inert gas (helium) from the service valve.

      2. Remove the suction seal cap.

      3. A01IO2W

        Position the suction port downward and slightly shake the compressor to drain oil.*1

        Note

        Be careful not to allow compressor oil to adhere to the pulley.

    2. A01IQIH

      Position the pulley side downward and turn the pulley in the direction indicated by the arrow once every 2 seconds 10 times.*2

      Note

      Keep your face away from the compressor port because turning the pulley may cause gas or oil to spew out.

    3. A01IT5M

      Quickly position the pulley side upward and turn the pulley in the direction indicated by the arrow once.*3

    4. Repeat procedure *1.*4

    1. Perform vacuum purging using a vacuum pump.

    2. Charge refrigerant HFC-134a (R134a).

      Standard
      440 +/-30 g (15.5 +/-1.1 oz)
      A01IS7RE26

      Note


      • Do not operate the cooler compressor before charging refrigerant as the cooler compressor will not work properly without any refrigerant, and will overheat.

      • Approximately 100 g (3.53 oz) of refrigerant may need to be charged after bubbles disappear. The refrigerant amount should be checked by measuring its quantity, and not with the sight glass.

  13. WARM UP ENGINE


    1. Warm up the engine at less than 1850 rpm for 2 minutes or more after charging the refrigerant.

      Note

      Be sure to warm up the compressor by turning the A/C switch on after removing and installing the cooler refrigerant lines (including the compressor) to prevent damage to the compressor.

  14. CHECK FOR REFRIGERANT GAS LEAK


    1. After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.

    2. Perform the operation observing the following instructions:


      • Stop the engine.

      • Secure good ventilation (the halogen leak detector may react to volatile gases other than refrigerant, such as evaporated gasoline or exhaust gas).

      • Repeat the test 2 or 3 times.

      • Make sure that some refrigerant remains in the refrigeration system.

        Tech Tips

        When the compressor is off: approximately 392 to 588 kPa (4.0 to 6.0 kgf/cm2, 57 to 85 psi).

    3. A01IPCYE30
      Text in Illustration
      *1 Check for Leakage
      *2 Halogen Leak Detector

      Using a halogen leak detector, check the refrigerant line for leakage.

    4. If a gas leak is not detected from the drain hose, remove the blower motor control (blower resistor) from the cooling unit. Insert the halogen leak detector sensor into the unit and check for gas leakage.

    5. Disconnect the pressure switch connector and wait for approximately 20 minutes. Bring the halogen leak detector close to the pressure switch and check for gas leakage.
