Installation [07/2020 - ]: Procedure

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

   Standard

   (Oil capacity inside the new compressor with motor assembly: 120 to 135 cc (4.06 to 4.56 fl.oz)) - (Remaining oil amount in the removed compressor with motor assembly) = (Oil amount to be removed from the new compressor)

   NOTE:

   • When checking the compressor oil level, observe the precautions on the cooler removal/installation.
   • If a new compressor with motor assembly is installed without removing some oil, there will be too much oil in the system due to the oil remaining in the pipes of the vehicle. Excessive oil in the system prevents heat exchange in the refrigeration cycle and causes ineffective cooling.
   • If the amount of oil remaining in the old compressor with motor assembly is too small, check the air conditioning system for oil leaks.
   • Be sure to use ND-OIL 11 or equivalent compressor oil. If any compressor oil other than ND-OIL 11 is used, compressor with motor assembly insulation performance may decrease, resulting in leakage of electric power.
   • Make sure to add compressor oil from the intake port.
   • When it is not possible to confirm the amount of oil in the system such as when compressor oil is spilt due to damage caused by a vehicle collision, etc., install a new compressor without draining any oil. If also replacing the cooler condenser assembly, do not add the supplied oil (40 cc (1.35 fl.oz)).

5. Remove the insulating tape from the connector (A).
6. Connect the connector (A) and slide the green-colored lock as shown in the illustration to securely lock it.
   WARNING:

   Make sure to wear insulated gloves.

   NOTE:

   Make sure that the connector is connected securely.

1. Remove the vinyl tape from the No. 1 cooler refrigerant discharge hose.
2. Sufficiently apply compressor oil to a new O-ring and the fitting surface of the compressor with motor assembly.

3. Install the O-ring to the No. 1 cooler refrigerant discharge hose.
   NOTE:

   • Keep the O-ring and O-ring fitting surface free of foreign matter.
   • Do not use any compressor oil other than ND-OIL 11 or equivalent. If any compressor oil other than ND-OIL 11 or equivalent is used, compressor motor insulation performance may decrease, resulting in leakage of electric power.
4. Connect the No. 1 cooler refrigerant discharge hose to the compressor with motor assembly with the bolt.

   Torque: 9.8 N*m (100 kgf*cm, 87 in.*lbf) 

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 with motor assembly.
