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
replacement 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
(se section 3.3.1).
Power up the system, and test it by repeating the Self-
Diagnostic Test as described in Chapter 4, Section 4.3.5.
