Replacing the Charcoal Filter
1. Verify that the EAGLE 2 is off.
2. Place the EAGLE 2 upside down on a flat surface or hold it upside down.
3. Unscrew the three case screws until they disengage from the top case.
They are captive screws so they will not fall off of the bottom case.
4. Turn the EAGLE 2 right side up and carefully lift the top case away from
the bottom case. Be careful not to lift it so far that it pulls on the main
PCB with the cable that connects the top case to the main PCB.
5. Lay the top case down next to the bottom case to allow access to the flow
system.
6. Locate the charcoal filter. It is next to the CO sensor at the front of the
flow chamber.
