3-10 | 3050 AM Moisture Analyzer
Gas Connections (Figure 3-5)
Install a main process shut-off valve and pressure regulator (recom-
mended) at the sample tap. Locate the analyzer as close as possible to the
sample source.
The amount of time that the analyzer gas fittings are left open should
be kept to less than a minute.
1. Remove the VCR plugs and gaskets from the sample inlet fitting (6)
and exhaust fitting (5). Discard the gaskets. Remove the cap from the
instrument air fitting (3). Keep the VCR fitting caps. If you have to
ship the analyzer or if it has to be disconnected for an extended period
of time, reinstall the caps using new gaskets.
2. Connect the sample input tube to the analyzer sample inlet 1/4 -inch
VCR fitting (6). Be sure to use a new gasket.
3. Connect the exhaust tube to the analyzer exhaust 1/4-inch VCR fitting (5).
Use a new gasket. The exhaust must be vented to an appropriate vent sys-
tem.
4. Connect a clean, dry instrument air supply (70-100 PSIG) to the instru-
ment air 1/4-inch Swagelok fitting (3). If the cleanliness of the air sup-
ply is questionable, connect using oil/air separators.
5. Check all sample input and exhaust fittings for leaks.
