Electric Inverter Compressor: Installation

INSPECT COMPRESSOR OIL
1. Gradually discharge inert gas (helium) from the service valve when replacing the electric inverter compressor with a new one. Drain the following amount of oil from the new electric inverter compressor before installation.
  Standard amount: (Oil capacity inside new electric inverter compressor 100 + 15 cc (3.52 + 0.53 fl.oz.)) - (Remaining oil amount in the removed compressor assembly with the motor (with motor compressor assembly)) = (Oil amount to be removed before installation)

  NOTE:
  - Observe the precautions on the cooler removal/installation procedures when checking the amount of compressor oil.
  - Because compressor oil remains in the pipes of the vehicle, if a new compressor is installed without removing the oil inside, the amount of oil becomes too great, preventing heat exchange in the refrigerant cycles and causing refrigerant failure and/or abnormal vibration.
  - Check for oil leakage if the remaining oil amount in the removed compressor is too low.
  - If any compressor oil other than ND-OIL 11 is used, compressor motor insulation performance may decrease, resulting in a leakage of electric power.
INSTALL ELECTRIC INVERTER COMPRESSOR ASSEMBLY
1. Temporarily install the compressor with the 2 bolts.
  NOTE: Install the bolts in the order indicated in the illustration.

INSTALL SUCTION HOSE SUB-ASSEMBLY
1. Sufficiently apply compressor oil to a new O-ring and the fitting surface of the electric inverter compressor assembly.
  Compressor oil: ND-OIL 11 or equivalent
  NOTE:
  - Do not use any compressor oil other than ND-OIL 11.
  - If any compressor oil other than ND-OIL 11 is used, compressor motor insulation performance may decrease, resulting in a leakage of electric power.
2. Install the O-ring to the suction hose.
3. Install the suction hose with the bolt.
  Torque: 9.8 N*m (100 kgf*cm, 87 in.*lbf)

INSTALL DISCHARGE HOSE SUB-ASSEMBLY
1. Sufficiently apply compressor oil to a new O-ring and the fitting surface of the electric inverter compressor.
  Compressor oil: ND-OIL 11 or equivalent
  NOTE:
  - Do not use any compressor oil other than ND-OIL 11.
  - If any compressor oil other than ND-OIL 11 is used, compressor motor insulation performance may decrease, resulting in a leakage of electric power.
2. Install the O-ring to the discharge hose.
3. Install the discharge hose with the bolt.
