5.2.4 Installing a New Micro-Fuel Cell

Before installing a new cell, check the O-ring in the base of the cell holder. Replace if worn or damaged.

1. Place the cell on the holder with the screen side facing down.

Note: There is a small location hole drilled in the holder. This hole mates with a guide pin on the bottom rear of the cell block. The hole in the cell block holder must align with the guide pin on the cell block.

2.With O-ring in place, align the guide pin with the hole on the cell holder. Then, with the holder, lift cell into the cell block.

3.Push the gate on the cell block down so that the slots on the side of the gate engage the locating screws on the side of the block. This forces the holder into position and forms a gas-tight seal.

5.2.5 Cell Warranty

The Class B-2CXL Micro-Fuel cell is used in the Model 3000TA-XL. This cell is warranted for 6 months 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 B-2CXL 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 TAI for the appropriate cell for measuring trace oxygen in the presence of CO2.

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.
