9. INSTRUMENT MAINTENANCE
Predictive diagnostic functions including data acquisition, failure warnings and alarms built into the
analyzer allow the user to determine when repairs are necessary without performing unnecessary,
preventative maintenance procedures. There is, however, a minimal number of simple procedures
that, when performed regularly, will ensure that the analyzer continues to operate accurately and
reliably over its lifetime. Repair and troubleshooting procedures are covered in Chapter 9 and
Chapter 11 of this manual.
9.1. Maintenance Schedule
Table 9-1 shows a typical maintenance schedule for the analyzer. Please note that in certain
environments (i.e. dusty, very high ambient pollutant levels) some maintenance procedures may
need to be performed more often than shown.
NOTE
A span and zero calibration check must be performed following some of the
maintenance procedures listed below.
See Sections 7.3, 7.6 and 7.9 for instructions on performing checks.
CAUTION
Risk of electrical shock. Disconnect power before performing any
operations that require entry into the interior of the analyzer.
NOTE
The operations outlined in this chapter must be performed by qualified
maintenance personnel only.
NOTE
The front panel of the analyzer is hinged at the bottom and may be opened to gain
access to various components mounted on the panel itself or located near the front of
the instrument (such as the particulate filter).
A locking screw locate at the top center of the panel and two fasteners located in the
upper right and left corners of the panel lock it shut (Figure 3-10).
