2. Unwrap and lay out the Sample and Vent Lines next to each other,
with the electrical leads at the analyzer.
3. Route the Sample and Vent Lines from the analyzer to the ASR900
Sample Probe.
Ensure there are no loops, sags, or other traps in the Sample and Vent
Lines. Provide support where needed.
Refer to the Sample/Vent Line Final “As-Built” drawings in the ana-
lyzer Documentation Package.
4. Make the Sample/Vent Line connections inside the Analyzer Oven
(Figure 3-5):
Non-Shelter Installations:
Route the Sample Line through the upper hole on the left side of the
Analyzer Oven. Connect it to the Sample Inlet fitting.
Route the Vent Line through the lower hole on the left side of the
Analyzer Oven. Connect it to the Sample Outlet fitting.
Shelter Installations:
Route the Sample Line through the hole marked “Sample Line” on the
side of the shelter and then through the upper hole on the side of the
Analyzer Oven. Connect it to the Sample Inlet fitting.
Route the Vent Line through the hole marked “Vent Line” on the
side of the shelter and then through the lower hole on the side of the
Analyzer Oven. Connect it to the Sample Outlet fitting.
Do not add extra insulation to the Sample Line or Vent Line. This
will result in a local hot spot and cause premature failure of the line.
5. Connect the Sample and Vent Lines to the ASR900 Sample Probe.
