Maintenance; Cleaning Or Replacing The Sample And Vent Lines - Ametek 241CE II User Manual

Maintenance

Generally, there is limited maintenance required to ensure the analyzer re-
mains operating at peak efficiency, other than that described in this section.
This maintenance, which includes parts that require replacement and cleaning,
is intended to ensure continued and proper operation of the analyzer.
The following sections discuss parts that can be replaced in the analyzer"

Cleaning or Replacing the Sample and Vent Lines

The Sample and Vent Lines should be inspected periodically, and any time
problems associated with the analyzer's measurements may be in question.
Generally, it is not necessary to clean the Sample and Vent Lines. However, if
there are liquids present in the lines, purge the lines with a dry gas or instru-
ment air.
Determining whether cleaning or replacing the line is necessary will depend
on the design of the Sample Line, and the availability of replacement tubing
and/or a cleaning medium. Example, replacing an unheated Sample Line may
be more practical than cleaning it. Cleaning the Sample Line with steam may
work if the contaminant is water soluble.
Whether cleaning or replacing the line, always purge the line with a dry gas
before reconnecting it to the analyzer.
Generally, it is necessary to replace the sample lines if the Sample or Vent Lines
are found to be sagging, have been bent, or show damage to the outer skin.
For tools and supplies required to replace the Sample/Vent Lines, see "Tools,
Equipment, and Supplies Required" in Chapter 2. If cleaning is required, use
Isopropanol or another similar non-abrasive cleaning agent.
