Install internal wires (3-phase models)

  1. From the power Printed Circuit Board (PCB) side, connect the following 3 wires to the power PCB as shown.

    Tighten to 2.3 N∙m (20 lbf·in).

    • Brown wire with white stripe
    • Black wire with white stripe
    • White wire with black stripe
  2. Route the wires through the slot in the middle of the center panel and then through the slot near the power switch.
  3. Slide the red insulating covers onto the new brown wire, white wire, and black wire.
  4. From the fan side, connect the following 3 wires to the power cord connection points on the center panel.

    Tighten to 2.3 N∙m (20 lbf·in).

    • Brown wire
    • White wire
    • Black wire
  5. Slide the red insulating covers up into place so that they cover the screws.

    Route the wires through the slot in the power switch area behind the front panel.

  6. Wrap a cable tie around the 6 new wires above the solenoid valve.
  7. Connect the 3 green ground wires to the ground stud on the center panel as shown in Internal ground wire connections.

    Tighten to 1.7 N∙m (15 lbf·in).

    Note:

    Rotate the ground wire terminals on the stud so that each wire points in a different direction.

  8. Connect the short ground wire to the air filter assembly.

    Tighten to 2.3 N∙m (20 lbf·in).

  9. Connect the long ground wire to the metal base plate for the magnetics assembly.

    Tighten to 1.7 N∙m (15 lbf·in).

  10. Connect the push-on connector for the third ground wire to the ground clip on the rear panel.
  11. Complete the following procedures:
    1. Install the power switch (3-phase).
    2. Install the component barrier.
    3. Install the plasma power supply cover and handle.
    4. Reconnect the gas supply.
    5. Reconnect the power cord.
