Install the air filter

  1. Put the brass bulkhead fitting into place inside of the rear panel.

    Make sure the fitting is pushed all the way in against the rear panel.

  2. Attach the nut onto the brass bulkhead fitting from the outside of the rear panel.

    Tighten to 13.5 N∙m (120 lbf·in).

  3. Connect the ground wire to the back right corner of the new air filter.

    Make sure the other end of the wire is connected to the ground stud on the center panel. Tighten to 2.3 N∙m (20 lbf·in).

  4. Put into place the new air filter with filter bowl and metal guard attached.

    Connect the end with the embossed arrow to the brass bulkhead fitting. Push-to-connect the air filter to the brass bulkhead fitting.

  5. Push-to-connect the looped gas supply hose into the side of the air filter.

    Make sure the hose retains a looped shape and is not kinked or cracked.

    Note:

    If the gas supply hose is kinked, discard it and replace it with a new hose. The integrity of the hose is compromised once the hose kinks.

  6. Complete the following procedures:
    1. Install the plasma power supply cover and handle.
    2. Reconnect the gas supply.
    3. Reconnect the power cord.
