1. Check the condition of all plastic tubing; replace it as
required – refer to Section 8.6, page 65 for multi-stream

ensure that the O-ring D is in place below the flange
on the compensator, and the skid washer E is in
place above the flange.
8.3 Automatic regeneration
The regeneration valve is energized for 1 minute. The analyzer
then starts a 2-hour regeneration recovery period. After the
recovery period a two-point calibration is initiated automatically.
A scheduled regeneration does not commence if the No
Samples diagnostic (see Appendix A.1, page 72) is active.
It is not advisable to perform a manual regeneration procedure
(see Section 8.4, page 63) if the No Samples diagnostic is
active.
To start an automatic regeneration:
1. Press the key (below the icon).
The Operator menus are displayed:
2. Press the key to scroll to the Enter Configuration menu
and press the key (below the icon).
The Access Level page is displayed:
3. Use the key to scroll to the Advanced access level
and press the key (below the Select prompt) to enter
the top level Configuration menus.
