5.3.5 Cell Warranty

The Class L-2C Micro-Fuel cell is used in the Model 3000TB. This cell
is a long life cell and is warranted for 1 year from the date of shipment. If
any other cell is supplied with your instrument, check the front of this
manual for any special information applying to your cell.
With regard to spare cells, warranty period begins on the date of ship-
ment. The customer should purchase only one spare cell (per section 5.3.1).
Do not attempt to stockpile spare cells.
The L-2C cell is not designed for applications where CO
major component in the sample, however concentrations of 1,000 ppm or
less will not adversely effect the cell performance. Consult the factory for
available options for either intermittent or continuous CO
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.
