Maintenance
6.1 Routine Maintenance
Aside from normal cleaning and checking for leaks at the gas
connections, routine maintenance is limited to replacing Micro-Fuel
cells and fuses, and recalibration. For recalibration, see Section 4.4
Calibration.
WARNING: SEE WARNINGS ON THE TITLE PAGE OF THIS
MANUAL.
6.2 Cell Replacement
The B-2CXL Micro-Fuel Cell and Insta-Trace Micro-fuel Cells are
sealed electrochemical transducers 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. Except where specifically noted, the information
pertains to both classes of cells.
6.2.1 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 3000TA-XL-EU, 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.
