5.2.5 Cell Warranty
The Class L-2 Micro-Fuel cell is used in the Model 3000TA. This cell
is a long life cell and is warranted for 1 year from the date of shipment. Note
any Addenda attached to the front of this manual for special information
applying to your instrument.
With regard to spare cells, warranty period begins on the date of ship-
ment. The customer should purchase only one spare cell (per section 5.2.1).
Do not attempt to stockpile spare cells.
The L-2 cell is not designed applications where CO
2
is a major
component in the sample, however concentrations of 1,000 ppm or less
will not adversely effect the cell performance. Consult TAI for available
options for either intermittent or continuous CO
2
exposure.
If a cell was working satisfactorily, but ceases to function before the
warranty period expires, the customer will receive credit toward the purchase
of a new cell.
If you have a warranty claim, you must return the cell in question to the
factory for evaluation. If it is determined that failure is due to faulty work-
manship or material, the cell will be replaced at no cost to you.
Note: Evidence of damage due to tampering or mishandling will
render the cell warranty null and void.
