After all piping and electrical connections have been made, and with the
analyzer 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.
WARNING
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
fill 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 fitting and con-
nection 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 fittings 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).
NOTE
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 flow rates as described
under "Adjusting the Sample Gas Flow Rate."
The procedure is complete.
