Maintenance
5.1 Routine Maintenance
Aside from normal cleaning and checking for leaks at the gas
connections, routine maintenance is limited to replacing Micro-fuel
Cells and recalibration. For recalibration, see Section 4 Calibration.
WARNING: SEE WARNINGS ON THE TITLE PAGE OF THIS
MANUAL.
5.2 Cell Replacement
A 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
discarded 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
recommends that one spare cell be purchased 9-10 months after
commissioning the Insta-Trans, 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.
