3.4Installing the Micro-Fuel Cell

The Micro-Fuel Cell is not installed in the cell block when the instrument is shipped. It must be installed before the analyzer is placed in service.

Once it is expended, or if the cell is exposed to air for too long, the

Micro-Fuel Cell will need to be replaced. The cell could also require replace- ment if the instrument has been idle for too long.

When the micro-Fuel Cell needs to be installed or replaced, follow the procedures in chapter 5, Maintenance, for removing and installing cells.

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 sample pressure is between 3 and 40 psig, according to the requirements of your process.

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