COMPRESSOR(for ZR Series Engine) INSTALLATION

PROCEDURE

  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.

      • for HFC-134a(R134a):

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

      • for HFO-1234yf(R1234yf):

        Be sure to use ND-OIL 12 for compressor oil.

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

      2. Remove the suction seal cap.

      3. E143917

        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. E143918

      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. E143919

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

    4. Repeat procedure *1.*4

    5. Repeat procedures *2 through *4 about 5 times to drain the standard amount of oil.

  2. INSTALL COMPRESSOR ASSEMBLY WITH PULLEY
