Removing EXO Components

Uninstalling EXO Diffusion Components

Figure 1. Uninstalling updated EXO Diffusion components
Figure 2. Uninstalling old EXO Diffusion components
Important:

If you are installing the Diffusion Upgrade kit (ACC-G7-EXO-DIFFUSION-MOD-KIT), please properly dispose of the old diffusion components. If you are converting to EXO Pump from an upgraded EXO Diffusion, do not discard your diffusion components. Upgraded diffusion components can be reinstalled as your area monitoring requirements change.

  1. Power off EXO. Use a Phillips screwdriver to remove the diffusion cartridge cover.
    Note:

    The captive screws should stay attached to the diffusion cartridge cover. Once the cover is removed, set it aside for storage.

  2. Remove the device’s gas sensor cartridge by pulling it out of its slot in the diffusion chamber, and then set it aside for re-installation into the device.
  3. Remove the diffusion module:
    1. Place EXO on its side with the diffusion module facing upwards.
    2. Remove the screws from the diffusion module and set them aside.
    3. Carefully lift the module, using your fingers to detach the module’s quick connect from EXO.
    4. Remove and set the diffusion module aside with the screws and diffusion cartridge cover.
    5. Stand EXO upright.
  4. Remove the diffusion chamber:
    1. Remove the screws and washers from each side of the diffusion chamber.
    2. Slide the chamber out from its slot, using your fingers to carefully detach the diffusion chamber coupling from EXO’s inlet tubing.

      Note:

      You may need to gently unclip or adjust the tubing by sliding it through the tube clamp to shorten the loop to allow for the movement of the diffusion gas chamber.

      Important:

      During any adjustment of the inlet tubing and clamp, take care not to dislodge the display ribbon cable connector. If you dislodge the connector, gently reconnect it before proceeding.

    3. Set aside the diffusion chamber with the other diffusion components.
  5. If you uninstalled upgraded diffusion components, collect and properly store the diffusion components set aside in the previous steps.

    If you uninstalled older diffusion components, properly dispose of the old diffusion components.

The device is ready for the installation of new components. For instructions on installing EXO Pump components, refer to Installing EXO Pump Components. For instructions on installing upgraded EXO Diffusion components, refer to Installing EXO Diffusion Components.
