3.4 Installing the Micro-Fuel Cell
The Micro-Fuel Cell is not installed in the cell block when the
instrument is shipped. Install it 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.
3.5 Testing 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.
• Verify that the restriction device has been properly installed (see
section 3.3.1).
• 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
operations:
1. Repeat the Self-Diagnostic Test as described in chapter 4, section
4.3.5.
