COMPRESSOR(for 1KR-FE) INSTALLATION

PROCEDURE

1. INSPECT COMPRESSOR OIL

   
   

   1. Remove the suction seal cap.

   2. 

      *1	VST Valve (Valve Inside Suction Port)
      *a	Protective Tape

      Using a screwdriver with its tip wrapped in protective tape, insert the screwdriver through the suction port and set the VST valve (valve inside suction port) to the open position.

      Note

      Be sure not to damage the piping contact surfaces with the tip of the screwdriver.

   3. 

      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.

   4. 

      With the pulley facing down, rotate the pulley in the direction shown by the arrow 10 times at a rate of approximately once every 2 seconds (*2).

      Note

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

   5. 

      Rotate the pulley once in the direction shown by the arrow while quickly turning the compressor so the pulley is up (*3).

   6. Proceed with the above procedure (*1) and drain the oil (*4).

   7. Drain the oil by repeating the procedures above approximately 5 times (from (*2) to (*4)).

      Standard (Amount of Oil to be Removed)
      Standard (Amount of Oil to be Removed) Amount of Oil Inside a New Compressor 30 cm3 60 cm3

      Tech Tips

      If too much oil has been removed, set the VST valve to the open position through the suction port, and add oil.

2. INSTALL COMPRESSOR WITH PULLEY ASSEMBLY

   
   

   1. 

      Install the compressor with the 4 bolts.

      Tech Tips

      Tighten the bolts in the order shown in the illustration.

      Torque:

      25 N*m  { 250 kgf*cm, 18 ft.*lbf }

   2. Connect the connector.

3. CONNECT NO. 1 COOLER REFRIGERANT DISCHARGE HOSE

   
   

   1. Remove the attached vinyl tape from the discharge hose.

   2. Apply sufficient compressor oil to a new O-ring and fitting surface of the compressor.

      Compressor oil
      for HFC-134a (R134a)
      ND-OIL 8 or equivalent
      for HFO-1234yf (R1234yf)
      ND-OIL 12 or equivalent

   3. Install the O-ring onto the discharge hose.

   4. Install the discharge hose onto the compressor with the bolt.

      Torque:

      9.8 N*m  { 100 kgf*cm, 87 in.*lbf }

4. CONNECT SUCTION HOSE SUB-ASSEMBLY

   
   

   1. Remove the attached vinyl tape from the suction hose.

   2. Apply sufficient compressor oil to a new O-ring and fitting surface of the compressor.

      Compressor oil
      for HFC-134a (R134a)
      ND-OIL 8 or equivalent
      for HFO-1234yf (R1234yf)
      ND-OIL 12 or equivalent

   3. Install the O-ring onto the suction hose.

   4. Install the suction hose onto the compressor with the bolt.

      Torque:

      9.8 N*m  { 100 kgf*cm, 87 in.*lbf }
