B) Automatic Calibration Unit (option)
Inside the Automatic Calibration Unit there are four filter cartridges: two activated carbon
cartridges, one particulate filter cartridge, and one desiccant cartridge. These should be replaced
annually.
First loosen the two screws in the back of the Automatic Calibration Unit and remove top cover
of the case. Do not pull with force as an ground wire is mounted to the cover. The ground wire
can be disconnected by pulling the plug on one end. The filter cartridges are now visible and can
be removed from their holding clamps. To replace the cartridges, the connected hose has to be
pulled off.
