1. When replacing the compressor with a new one:
   1. Remove the drain bolt (washer).

      *a	Drain Bolt (Washer)

   2. Gradually discharge the inert gas from the service valve. Then drain the following amount of oil from the new compressor before installation so that the amount of oil contained in it is the same as that in the compressor to be replaced.

      *a	Removed Compressor
      *b	Amount of oil to be drained from removed compressor
      *c	Amount of oil remaining in the reserve chamber (60 cc (2.03 fl.oz))

      HINT: 

      New compressors are filled with sufficient oil for the whole air conditioning system. Therefore, it is necessary to drain oil from the new compressor to compensate for oil remaining in the condenser and cooling unit.

      Standard

      (The amount of compressor oil inside a new compressor and magnetic clutch: 70 (+15) cc (2.37 (+0.51) fl.oz)) - (The amount of compressor oil remaining in the removed compressor and magnetic clutch) = The amount of compressor oil to be removed when replacing the compressor and magnetic clutch

      NOTE:

      • When A + 60 cc (2.03 fl.oz) exceeds the standard oil fill volume specified for the compressor by part number, install the compressor without adjusting the oil volume.

        Example:

        If A = 45 cc (1.52 fl.oz), A + 60 cc (2.03 fl.oz) = 105 cc (3.55 fl.oz). If the standard volume is 100 cc (3.38 fl.oz), install the compressor as is.

      • If the amount of oil remaining in the removed compressor is too low, check for oil leaks.
      • Use ND-OIL 12 or equivalent for compressor oil.
   3. Install the drain bolt (washer).

      Torque: 30 N*m (306 kgf*cm, 22 ft.*lbf) 

2. If draining the oil is difficult, drain the oil using the following procedure:
   1. Remove the suction seal cap.
   2. Lightly shake the compressor with the suction port facing down, and drain the oil (*1).

      NOTE:

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

3. With the pulley facing down, rotate the hub as shown in the illustration 10 times at a rate of approximately once every 2 seconds (*2).

   WARNING:

   If the pulley is rotated, refrigerant or oil may spray out. Thus, keep your face away from the compressor port.

4. Rotate the hub once as shown in the illustration while quickly turning the compressor with the pulley facing up (*3).
