3.4Installing the Micro-Fuel Cell

The Micro-Fuel Cell, Model B-2CXL is not installed in the cell block when the instrument is shipped. Install it before the analyzer is placed in service.

The Micro-Fuel cell is located inside the stainless steel cell block behind the front panel (see Figure 3-8). To install the cell:

1.Remove power to the instrument by unplugging the power cord at the power source.

2.Open the front panel door by pressing the release button on the top right corner of the door all the way in with a narrow gauge tool.

3.With one hand placed underneath the cell block ready to catch the Micro-Fuel cell , lift up on the stainless steel gate in front of the cell block. This releases the cell and cell holder from the block. The cell and holder will fall out in your hand.

CAUTION:

The cell is shipped separately inside two bags filled with oxygen-free inert gas. Extreme care must be taken to ensure that the cell is exposed to air for the very minimum amount of time, including during installation.

As an example, an air exposure of 3 to 5 minutes may require 24 hours or longer before the cell recovers to less than 0.5 ppm on an oxygen free sample gas. On the other hand, if the air exposure is limited to less than 10 seconds, the recovery time will be reduced to two hours, or less.

3.5Testing the System

Before plugging the instrument into the power source:

Check the integrity and accuracy of the gas connections. Make sure there are no leaks.

Check the integrity and accuracy of the electrical connections. Make sure there are no exposed conductors.

Check that inlet sample pressure is within the accepted range (see section 3.3.1).

Power up the system, and test it by performing the following operation:

1.Repeat the Self-Diagnostic Test as described in chapter 4, section 4.3.5.
