Preventive Maintenance

6-2 | Model 241CE II Hydrocarbon Dewpoint Analyzer
Generally, there is limited maintenance required for the analyzer. This sec-
tion includes an Analyzer Preventive Maintenance Schedule to follow to
ensure continued and proper operation of the analyzer. This chapter also
describes parts that require replacing and/or cleaning, and the frequency
in which they should be replaced/cleaned, according to the Preventive
Maintenance Schedule.
To reduce the occurrence of problems with the analyzer, AMETEK recom-
mends that you follow the Preventive Maintenance Schedule. Since the
Measuring Cell is the component that is most susceptible to problems,
such as contamination, the primary objective of the Preventive Mainte-
nance Schedule is proper care of the Measuring Cell Assembly.
!
Preventing leaks in the sample system is critical to proper analyzer
operation. The analyzer's sample system must be leak-checked when-
CAUTION
ever it has been dismantled for maintenance or repair.
Refer to the Preventive Maintenance Schedule for suggested actions and
their frequency when caring for the analyzer. Details and drawings that
are intended to assist you when changing out parts can be found through-
out this chapter.
Generally, the preventive and general maintenance consists of:
• Ensuring operating temperatures are within range of their setpoints
and ambient temperatures are suitable.
• Ensuring the ambient temperature is at least 15 °C (27 °F) above the
highest expected hydrocarbon dewpoint temperature. It is extremely
important to maintain a relatively stable ambient temperature in the
vicinity of the analyzer, with no rapid fluctuations.
• Determining if it is necessary to clean the Measuring Cell and sample
system, and how to clean the Measuring Cell and its components.
Also, determining if Measuring Cell parts require replacement, and
changing out the necessary parts.
• Cleaning and changing out the Filterblock Assembly components.
• Cleaning the Electronics Enclosure's flamepath and checking it for
damage (scratches, dents, etc.).
