5.1 Routine Maintenance

Aside from normal cleaning and checking for leaks at the gas connec-
tions, routine maintenance is limited to replacing Micro-Fuel cells and fuses,
and recalibration. For recalibration, see Section 4.4 Calibration.

WARNING: SEE WARNINGS ON THE TITLE PAGE OF THIS

MANUAL.

5.2 Cell Replacement

The B-2CXL Micro-Fuel Cell is a sealed electrochemical transducer
with no electrolyte to change or electrodes to clean. When the cell reaches
the end of its useful life, it is replaced. The spent fuel cell should be dis-
carded according to local regulations. This section describes fuel cell care as
well as when and how to replace it.
5.2.1 Storing and Handling Replacement Cells
To have a replacement cell available when it is needed, TAI recom-
mends that one spare cell be purchased 9-10 months after commissioning the
Ultra Trace 3000, or shortly before the end of the cell's one year warranty
period.

CAUTION: Do not stockpile cells. The warranty period starts on

the day of shipment.

The spare cell should be carefully stored in an area that is not subject to
large variations in ambient temperature (75 °F nominal) or to rough handling.
