      *a New Compressor Assembly With Pulley
      *b Removed Compressor Assembly With Pulley
      *c Drain Extra Oil (A - B)

      When replacing the compressor assembly with pulley with a new one, gradually discharge the refrigerant gas (helium) from the service valve. Then drain the following amount of compressor oil from the new compressor assembly with pulley before installation, so that the amount of compressor oil contained in it is the same as that in the compressor assembly with pulley to be replaced.

      Tech Tips

      New compressor assembly with pulley are filled with sufficient compressor oil for the whole cycle. Therefore, it is necessary to drain residual compressor oil from the condenser and cooling unit.

      Standard
      (The amount of compressor oil inside a new compressor: 60 (+15) cc (2.0 (+0.51) fl.oz.)) - (The amount of compressor oil remaining in the removed compressor) = The amount of compressor oil to be removed when replacing the compressor assembly with pulley

      Note


      • When checking the compressor oil level, observe the precautions for cooler removal/ installation.

      • 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.

      • Use ND-OIL8 or equivalent for compressor oil.

    2. If draining the compressor oil is difficult, drain the compressor oil using the following procedure:


      1. Rotate the pulley, and drain the compressor oil.

        Note


        • Do not allow the pulley to come into contact with the compressor oil.

        • If the pulley is rotated, refrigerant or compressor oil might splash out. Thus, keep your face away from the compressor port.

  2. INSTALL COMPRESSOR ASSEMBLY WITH PULLEY


    1. Using a "TORX" socket wrench (E8), install the compressor assembly with pulley with the 2 stud bolts.
