5-6 | IPS-4 Dual Bench (UV / IR) Analyzer
Every Six Months Sheltered Systems
If your analyzer system is installed in a custom shelter, check the
air lters for the shelter purge and air conditioning systems and
replace them if necessary. Depending on the location of the site
and its environmental conditions, it may be necessary to check and
replace these lters more frequently.
Every Six Months Sample/Vent Lines
Inspect the Sample Line and Vent Line for sags, sharp bends, or
damage to the outer skin. If necessary, take appropriate safety pre-
cautions and replace the lines. Perform a leak check on all associ-
ated ttings after replacing any line(s).
Every Year Measuring Cell
Clean the Measuring Cell and the rest of the analyzer sample sys-
tem. This schedule is a minimum requirement. If other conditions
are found to be present, as outlined in this chapter under “Measur-
ing Cell Preventive Maintenance,” cleaning may be required more
frequently.
At the same time, replace the o-rings (always) and windows and/or
window/mirror combinations (if chipped, cracked, or scratched).

Lamp Assembly” in this chapter.
3–5 Years Infrared Source Assembly
Replace the Infrared Source Assembly. The assembly may need to
be replaced sooner if information from the analyzer diagnostics indi-
cates related alarms. Refer to “Replacing the Infrared (IR) Source
Assembly” in this chapter.
