5.3.5 Cell Warranty

The Class L-2C Micro-Fuel cell is used in the Model 3020T. 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 CO2 is a

major component in the sample, however concentrations of 1,000 ppm or less will not adversely effect the cell performance. Consult Analytic Instru- ments for available options for either intermittent or continuous CO2 expo- sure.

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.

5.4Fuse Replacement

1. Disconnect the Unit from its power source.

2.Place a small screwdriver in the notch in the fuse holder cap, push in, and rotate 1/4 turn. The cap will pop out a few millimeters. Pull out the fuse holder cap and fuse, as shown in Figure 5-3.
