Order a replacement cell shortly after the instrument is placed in service,
and each time the cell is replaced thereafter.
CAUTION: DO NOT STOCKPILE SPARE CELLS. Due to the shelf life of the
cells, only one per instrument should be in reserve.
The spare cell should be carefully stored in an area that is not subject to
large variations in ambient temperature (24°C nominal), and in such a way
as to eliminate any possibility that the cell could be damaged. Do not open
the cell package until you are ready to place the cell in the instrument. If
the cell package is punctured and air permitted to enter, the cell will imme-
diately begin to react to the presence of oxygen.
After you install the new cell, follow the procedures outlined in the
Startup section (3.2 and 3.3) of the manual.

If it is determined that failure is due to faulty workmanship or parts, the
cell will be replaced at no cost to the customer. If a cell was working
satisfactorily, but ceases to function before the warranty period expires, the
customer will receive credit, on a pro-rated basis, toward the purchase of a
new cell. Customers with warranty claims must return the cell in question to
the factory for evaluation.
WARNING: Any evidence of tampering, or damage through mishandling,
will make the cell warranty null and void.
