COMPRESSOR(for 1ND-TV) INSTALLATION

PROCEDURE


  1. INSPECT COMPRESSOR OIL


    1. When replacing the compressor assembly with a new one, gradually discharge the inert gas (helium) from the service valve, and drain the following amount of oil before installation.

      Standard (Capacity of oil to be drained when replacing)
      (The amount of compressor oil inside a new compressor assembly with pulley: 80 (+15) cc (2.71 (+0.507) fl.oz.)) - (The amount of compressor oil remaining in the removed compressor assembly with pulley) = The amount of compressor oil to be removed when replacing the compressor assembly with pulley

      Note


      • If a new compressor assembly with pulley is installed without removing the same amount of compressor oil as is remaining in the pipes, the amount of compressor oil will be excessive. This prevents heat exchange in the refrigerant cycle and will cause a refrigeration failure.

      • If the amount of compressor oil remaining in the removed compressor assembly with pulley is too low, check for compressor oil leakage.

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

    2. Remove the suction seal cap.

    3. A01LVJZ

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

      Note

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

    4. A01M0Y9

      Position the DL pulley side downward and turn the pulley in the direction indicated by the arrow once in 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.

    5. A01LVNQ

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

    6. Repeat procedure (*1). (*4)

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

  2. INSTALL COMPRESSOR ASSEMBLY WITH PULLEY


    1. A01LX1QE01

      Using an E8 "TORX" socket, temporarily install the compressor assembly with pulley with the 2 stud bolts.

      Torque:
      9.8 N*m  { 100 kgf*cm, 87 in.*lbf }

      Tech Tips

      Tighten the stud bolts in the order shown in the illustration to temporarily install the compressor assembly with pulley.

    2. A01M2Q5C02
      A01M03W Bolt
      A01LZQW Nut

      Install the compressor assembly with pulley with the 2 bolts and 2 nuts.

      Torque:
      25 N*m  { 255 kgf*cm, 18 ft.*lbf }

      Tech Tips

      Tighten the bolts and nuts in the order shown in the illustration to install the compressor assembly with pulley.

    3. Connect the connector.

  3. CONNECT SUCTION HOSE SUB-ASSEMBLY


    1. Remove the vinyl tape from the suction hose sub-assembly.

    2. Sufficiently apply compressor oil to a new O-ring and the fitting surface of the compressor assembly with pulley.

      Compressor Oil
      ND-OIL 8 or equivalent

    3. Install the O-ring onto the suction hose sub-assembly.

    4. Install the suction hose sub-assembly to the compressor assembly with pulley with the bolt.

      Torque:
      9.8 N*m  { 100 kgf*cm, 87 in.*lbf }

  4. CONNECT DISCHARGE HOSE SUB-ASSEMBLY


    1. Remove the vinyl tape from the discharge hose sub-assembly.

    2. Sufficiently apply compressor oil to a new O-ring and the fitting surface of the compressor assembly with pulley.

      Compressor Oil
      ND-OIL 8 or equivalent

    3. Install the O-ring onto the discharge hose sub-assembly.

    4. Install the discharge hose sub-assembly to the compressor assembly with pulley with the bolt.

      Torque:
      9.8 N*m  { 100 kgf*cm, 87 in.*lbf }
