REFRIGERANT LINE INSTALLATION

PROCEDURE


  1. INSTALL PIPING CLAMP (for Low Pressure)


    1. w/o Sub-cool Accelerator


      1. Remove the vinyl tape from the open ends of the suction pipe sub-assembly and suction hose sub-assembly.

      2. B005PEHC03
        *1 Suction Hose Sub-assembly
        *2 Piping Clamp
        *a Groove

        Install a new piping clamp to the suction hose sub-assembly.

        Note


        • Securely engage the inside step of the piping clamp into the groove of the suction hose sub-assembly.

        • Do not widen the opening of the piping clamp more than the diameter of the suction hose sub-assembly when installing it.

        • Do not install the piping clamp with the large diameter section in the wrong direction.

      3. Thoroughly coat 2 new O-rings and the contact surface of the suction hose sub-assembly with compressor oil.

        Compressor Oil
        ND-OIL 8 or equivalent
      4. Install the 2 O-rings to the suction hose sub-assembly.

        Note

        Keep the O-rings and sealing surface of the suction pipe sub-assembly free from foreign matter.

      5. B005PZ2C03
        *a Large Diameter Section of Piping Clamp
        *b Alignment Mark

        Engage the suction pipe sub-assembly and suction hose sub-assembly by matching the alignment marks.

        Note

        Engage the parts by holding the pipe, not the piping clamp.

      6. B005P0GC03
        *a Large Diameter Section of Piping Clamp

        Securely insert the piping clamp to the point where the large diameter section of the piping clamp is covered by the suction pipe sub-assembly.

        Tech Tips


        • When inserting, make sure that a click sound is heard.

        • Check that the suction hose sub-assembly is securely inserted by pulling it.

    2. w/ Sub-cool Accelerator


      1. Remove the vinyl tape from the open ends of the No. 2 air conditioner tube and accessory assembly and suction hose sub-assembly.

      2. B005PEHC03
        *1 Suction Hose Sub-assembly
        *2 Piping Clamp
        *a Groove

        Install a new piping clamp to the suction hose sub-assembly.

        Note


        • Securely engage the inside step of the piping clamp into the groove of the suction hose sub-assembly.

        • Do not widen the opening of the piping clamp more than the diameter of the suction hose sub-assembly when installing it.

        • Do not install the piping clamp with the large diameter section in the wrong direction.

      3. Thoroughly coat 2 new O-rings and the contact surface of the suction hose sub-assembly with compressor oil.

        Refrigerant Compressor Oil
        HFC-134a (R134a) ND-OIL 8 or equivalent
        HFO-1234yf (R1234yf) ND-OIL 12 or equivalent
      4. Install the 2 O-rings to the suction hose sub-assembly.

        Note

        Keep the O-rings and sealing surface of the No. 2 air conditioner tube and accessory assembly free from foreign matter.

      5. B005PZ2C03
        *a Large Diameter Section of Piping Clamp
        *b Alignment Mark

        Engage the No. 2 air conditioner tube and accessory assembly and suction hose sub-assembly by matching the alignment marks.

        Note

        Engage the parts by holding the pipe, not the piping clamp.

      6. B005P0GC03
        *a Large Diameter Section of Piping Clamp

        Securely insert the piping clamp to the point where the large diameter section of the piping clamp is covered by the No. 2 air conditioner tube and accessory assembly.

        Tech Tips


        • When inserting, make sure that a click sound is heard.

        • Check that the suction hose sub-assembly is securely inserted by pulling it.

  2. INSTALL PIPING CLAMP (for High Pressure)


    1. Remove the vinyl tape from the No. 2 air conditioner tube and accessory assembly and air conditioner tube and accessory assembly.

    2. Sufficiently apply compressor oil to 2 new O-rings and the fitting surfaces of the air conditioner tube and accessory assembly.

      Refrigerant Compressor Oil
      HFC-134a (R134a) ND-OIL 8 or equivalent
      HFO-1234yf (R1234yf) ND-OIL 12 or equivalent
    3. Install the 2 O-rings to the air conditioner tube and accessory assembly.

      Note

      Keep the O-rings and sealing surface of the No. 2 air conditioner tube and accessory assembly free from foreign matter.

    4. Install the No. 2 air conditioner tube and accessory assembly to the air conditioner tube and accessory assembly.

    5. B005P4TC02
      *a Correct
      *b Incorrect
      *c No Gap
      *d Gap

      Install the piping clamp to the No. 2 air conditioner tube and accessory assembly.

      Note

      Make sure that the piping clamp is engaged securely with no gap.
