MAINTENANCE
Series C16 gas detectors require little maintenance. Sensors do not have a regular
service requirement other than calibration, and pumps are sealed and permanently lubricated.
The only item in the instrument that requires periodic maintenance is a filter that protects the
pump against particulate that might cause it to stall. Check the filter at least monthly and replace
when dirty.
The filter is a small disk of filter fabric that is located in the sensor recess behind the flow
manifold. Unscrew the two captive screws holding the flow manifold in place and remove the
manifold. The filter is just above the sensor and is simply pressed into the filter cavity. Remove
the old filter disk and put a new one in its place. A bag of filters is supplied with the instrument
and additional filter disks are available from ATI.
