back side of the instrument. Two of these screws also secure the flow
chamber.

flow chamber.
4. Grab the exhaust tube and pull it gently away from the unit to slide the
flow chamber out of the unit. The CO (charcoal) filter may come out.
5. To replace the LEL filter, remove the old one from its recess in the sensor
gasket and replace it with the new one making sure that it is properly
seated. You do not have to remove the sensor gasket to replace the LEL
filter. It sits in a recess on top of it.
