Maintenance
Generally, there is limited maintenance required to ensure the analyzer
remains operating at peak efficiency, other than that described in the “An-
alyzer Preventive Maintenance Schedule.” This section discusses preven-
tive maintenance that must be followed to ensure continued and proper
operation of the analyzer. This section also describes parts that require
replacing and the frequency in which they should be replaced, according
to this schedule.
Preventive Maintenance
To reduce the occurrence of problems with the analyzer, AMETEK recom-
mends that you follow the “Analyzer Preventive Maintenance Schedule,”
as outlined in the following pages. Since most analyzer problems originate
within the sample handling system, the primary objective of the preven-
tive maintenance schedule is proper care of the sample system.
For Gas Applications:
Plugs in the sample system generally can be avoided by ensuring all
components of the sample system operate at least 10 °C (18 °F) above the
sample dew point temperature. The risk of developing a collection of
liquids in low spots or plugging in the sample system is further reduced
by sloping the Sample Line to the analyzer and the Vent Line back to the
sample stream or other dispersal method.
Preventing leaks in the sample handling system is critical to proper
analyzer operation. The analyzer sample system must be leak checked
whenever it has been dismantled for maintenance or repair. Refer to
“Sample System Leak Check” in Chapter 3 for details.
The “Analyzer Preventive Maintenance Schedule” suggests actions and
their frequency when caring for the analyzer. Procedures and drawings
that are intended to assist you when changing out parts can be found in
appropriate sections in this chapter or in a Manual Supplement which is
included in the “Supplemental Information”section of this manual and/or
the analyzer Documentation Package .
