3-10 | Heated Acid Gas Sample Probe (Large Diameter)
7. Prepare the HAG Probe for installation by ensuring its Sample (Red)
and Vent (Black) isolation handles are closed.
8. Install the new HAG Probe (see Figure 3-2):
If mounting the HAG Probe on a vertical section of pipe, it is criti-
cal to position the probe with the Vent Valve (Black handle) angled
downward slightly.
Apply a thin bead of pipe sealant on the lower threads of the Sample
Probe Pipe Adapter and thread it into the replacement flange, being
careful not to cross-thread the threads on the HAG Probe.
Remove the existing upper flange/Sample Valve assembly. Using a
gasket suitable for the application, secure the HAG Probe/replacement
flange assembly to the process duct flange.
9. Lay out the Sample and Vent Lines between the HAG Probe and the
analyzer or its shelter.
10. Connect the Sample and Vent Lines to the HAG Probe.
The Sample Line fitting is on the same side of the Sample Probe as the
Sample isolation valve (Red handle). The Vent Line fitting is on the
same side of the HAG Probe as the Vent isolation valve (Black handle).
Do not install the Insulating Jacket on the HAG Probe at this time.
This will be done after the analyzer and HAG Probe have been pow-
ered up and leak-checked (with no leaks).
11. Connect the Sample and Vent Lines to the Sample Inlet/Outlet fittings
on the analyzer:
Non-Shelter Installations:
Route the Sample Line to the analyzer and connect it to the Sample
Inlet fitting.
Route the Vent Line to the analyzer and connect it to the Vent Outlet
fitting.
