Installing the HAG Sample Probe in New Applications
For installation drawings, refer to the “Supplemental Information” section
of the analyzer manual, or the Documentation Package shipped with the
analyzer or the HAG Sample Probe.
To install the HAG Probe:
1. Prepare the HAG Probe for installation:
• Ensure the probe end is the proper length for the process duct be-
ing sampled from. If necessary, cut the probe end so that it
extends 30–50 % into the process duct.
• Ensure the Sample (Red) and Vent (Black) isolation handles on the
HAG Probe are closed.
Potentially lethal concentrations of H
2
S and/or other toxic gases are
present in the process. Before proceeding, follow all necessary safety
precautions, such as wearing a supply air apparatus.
2. Install the new HAG Probe:
Applications with a Threaded connection:
Apply a thin bead of pipe sealant on the lower threads of the Sample
Probe Pipe Adapter. Use care to avoid cross-threading the threads on
the Sample Probe.
Applications with a Flange :
Remove the existing flange blind and, using a gasket suitable for
the application, connect the Sample Probe (comes with replacement
flange assembly) to the flange on the process duct.
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.
3. Lay out the Sample and Vent Lines between the probe and the
analyzer.
