Compressor ASSY: Installation

1. When replacing with a new compressor ASSY (with magnet clutch), release inert gas (helium) gradually from the position shown by the arrow in the figure, and then discharge the oil quantity shown below for installation.

   Standard value: (70 mL of oil in a new compressor ASSY (with magnet clutch)) - (Oil left in the removed compressor ASSY (with magnet clutch)) = (Quantity to be discharged during replacement)

   CAUTION:

   • To check the compressor oil quantity, strictly observe the cautions for installation/removal.
   • The compressor oil remains in the pipe of the vehicle. Therefore, if oil in the new compressor ASSY (with magnet clutch) is not discharged, the oil quantity is increased. It may disturb heat exchange of the refrigerant cycle, resulting in adverse effect such as poor cooling or noise/vibration.
   • If the oil quantity in the removed compressor ASSY (with magnet clutch) is small, check for oil leak.
   • Be sure to use ND-OIL8 for the compressor oil.

1. Temporarily install the compressor ASSY (with magnet clutch) with the 3 bolts.
2. Install the compressor ASSY (with magnet clutch) with the 3 bolts in the order shown in the figure.

   Standard value: T=36N.m {367kgf.cm} {26.6ft.lbf}

3. Connect the connector.

1. Remove the vinyl tape wrapped around the joint of cooler refrigerant discharge hose NO. 1.
2. Apply sufficient amount of compressor oil (ND-OIL8) to new O-rings and the fitting area of the compressor ASSY (with magnet clutch).
3. Install the O-ring on cooler refrigerant discharge hose NO. 1.
   CAUTION: Do not allow the O-ring and the O-ring seal to have deposit of dirt.
4. Connect cooler refrigerant discharge hose NO. 1 to the compressor ASSY (with magnet clutch) with the bolt.

   Standard value: T=10N.m {102kgf.cm} {7.4ft.lbf}

1. Remove the vinyl tape wrapped around the joint of the suction hose SUB-ASSY.
2. Apply sufficient amount of compressor oil (ND-OIL8) to new O-rings and the fitting area of the compressor ASSY (with magnet clutch).
3. Install the O-ring on the suction hose SUB-ASSY.
   CAUTION: Do not allow the O-ring and the O-ring seal to have deposit of dirt.
4. Connect the suction hose SUB-ASSY to the compressor ASSY (with magnet clutch) with the bolts.
