After all piping and electrical connections have been made, and with the ana-
lyzer powered down:
1. Close the Sample Line isolation valve at the process pipe. Close the Vent
Line isolation valve at the vent location (or cap the Vent Line).
Before applying any pressure to the sample system (from the process),
visually and physically check all plumbing connections.
2. Slowly open the isolation valve at the process pipe to introduce gas into
the sample system.
If other isolation valves are included within the sample system, slowly
open them, too.
3. Partially dial in the pressure regulator. Open it enough to allow gas to ll
the sample system.
4. Allow the pressure within the sample system and the Measuring Cell to
equilibrate to line pressure (approximately 2 minutes).
While the sample system is pressurized, check each tting and connection
in the sample system for leaks using a detergent-based leak detector (e.g.
Snoop
®
).
5. If a gas leak is detected, perform the appropriate repair procedures and
retest the ttings until all leaks have been eliminated.
6. Close all doors and covers and secure them with their screws.
The torque needed to fasten M10 screws on the Enclosure is 9.0 Nm,
±0.7 Nm (80 in.-lb, ±9 in.-lb).
7. Power up the analyzer and open the Vent Line isolation valve(s), or remove
the cap.
8. Open the Sample Line isolation valve(s).
9. Adjust the pressure regulator to achieve proper ow rates as described
under “Adjusting the Sample Gas Flow Rate.”
The procedure is complete.
