3.
Once detached, remove the four socket head cap screws in the filter
body.
4.
Open the filter body and replace the membrane.
5.
Reassemble the filter body and attach the filter to the analyzer.
6.
Connect the 1/8" inlet tubing and the 1/4" compression fitting to the
sample supply port on the analyzer.
7.
Tighten all new compression fittings 1-1/4 turns with a wrench from
finger tight. For connections with previously swaged ferrules, thread
the nut to the previously pulled up position, then tighten slightly with
a wrench. Secure tubing to appropriate structural supports as
required.
8.
Check all connections for gas leaks. SpectraSensors recommends
using a liquid leak detector.
Contamination
Contamination and long exposure to high humidity are valid reasons for
periodically cleaning the gas sampling lines. Contamination in the gas sampling
lines can potentially find its way to the sample cell and deposit on the optics or
interfere with the measurement in some other way. Although the analyzer is
designed to withstand some contamination, it is recommended to always keep
the sampling lines as contamination free as possible.
To keep the sampling lines clean:
1.
Make sure that a membrane separator filter (included with most
systems) is installed ahead of the analyzer and operating normally.
Replace the membrane if necessary. If liquid enters the cell and
accumulates on the internal optics, a
Power Fail
will result.
2.
If mirror contamination is suspected, see
“Cleaning the Mirrors”
on page A-3.
3.
Turn off the sample valve at the tap in accordance with site lock-out,
tag-out rules.
4.
Disconnect the gas sampling line from the supply port of the
analyzer.
5.
Wash the sampling line with alcohol or acetone and blow dry with
mild pressure from a dry air or nitrogen source.
6.
Once the sampling line is completely free of solvent, reconnect the
gas sampling line to the supply port of the analyzer.
Do not exceed 10 psig (0.7 barg) in sample cell. Damage to cell
may result.
