Replacing the Charcoal Filter

1. Verify that the CO-04C is off.
2. Remove the rubber boot, if installed.
3. Use a small Phillips screwdriver to unscrew the 4 screws that attached the front case to the

rear case.

4. Turn the instrument right side up. The screws are not captive and may fall out. Be sure not

to lose them.

5. Remove the front case from the rear case.

6. Turn the front case upside down.
7. If the sensor stayed in the front case, remove the sensor.
