HARDWARE MAINTENANCE PROCEDURES
Perform the following procedures as standard maintenance per Table 5-1.
ATTENTION
COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Ensure there is no power to the unit so that there is no vacuum
of any kind when changing anything in the pneumatic lines.
REPLACING THE SAMPLE FILTER
Inspect the particulate filter often for signs of plugging or contamination.
To change the filter:
1. Turn OFF the analyzer to prevent drawing debris into the instrument.
2. Open the hinged rear panel and disconnect the pneumatic fittings, using the
appropriate wrenches, and remove the disposable sample filter.
3. Insert new filter and reconnect pneumatic fittings.
4. Close the front panel
Figure 5-5. Replacing the Sample Filter
REPLACING THE AREF SCRUBBER AND FILTER ASSEMBLY
The AREF filter assembly consists of the AREF filter, which is a backup particulate
filter, and the charcoal filter, which is an NO
2
gas scrubber.
1. Turn OFF the analyzer (this is important to avoid potential for contamination of
the measurement cell), unplug the power cord and remove the cover.
2. Using snips, remove the zip tie holding the pair of fittings to the mounting
bracket.
3. Using a wrench, disconnect the fitting that is connected to the AREF filter. Then
disconnect the fitting that is connected to the charcoal filter. This will free up the
AREF filter assembly.
