The sample pump head periodically wears out and must be replaced when the reaction cell
pressure (Rx Cell Press) exceeds 10 in-Hg-A (at sea level; adjust this value accordingly for
elevated locations).

A pump rebuild kit is available from the factory. Refer to the label on the pump for the
part number. Instructions and diagrams are included in the kit.

A span check and re-calibration after this procedure is necessary as the response of
the analyzer changes with the Rx Cell Press.
