has been detected in
the input oxygen gas.
Go to Simulate menu and read the CO
2
analyzer
’s CO
2
ppm value. If this value
is greater than 250-300ppm, check the
oxygen purity.
Check the quality of oxygen
following the Oxygen Purity Test
procedures in
Section 7
Analyzer Commissioning
and Startup .
If the oxygen purity test is
satisfactory, open CO
2
analyzer
and clean the optics.
If problem persists, replace the
CO
2
Analyzer filters.
If the oxygen purity test is
unsatisfactory, replace the oxygen
concentrator.
18_LIQUID LEAK DET
BioTector’s liquid leak detector is
activated by the three liquid leak
detector points fitted in the BioTector.
First point is in the main analysis
enclosure cabinet, the second point is
in the oxygen concentrator cabinet and
the third point is in the Mixer Reactor.
See figure 2 in Section
4.1.1
Analysis Enclosure for details.
Check for a liquid leak in the
BioTector main cabinet and in the
oxygen concentrator cabinet.
Check for a liquid leak in Mixer
Reactor by unplugging the leak
detector connector on the bottom
of the reactor.
Rectify the leak.
