SpectraSensors, Inc. 131
10 Maintenance/Service
Technicians are expected to be educated in the handling of hazardous sample gas
and shall follow all safety protocols established by the customer that are
necessary for servicing the analyzer. This may include, but is not limited to,
lockout/tag-out procedures, toxic gas monitoring protocols, personal protection
equipment (PPE) requirements, hot work permits and other precautions that
address safety concerns related to performing service on process equipment
located in hazardous areas.
Personnel shall use protective gear (e.g., gloves, masks, etc.) while exposed to
gases or vapor streams.
Cleaning and
Decontamination
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 mem-
brane if necessary. If liquid enters the cell and accumulates on the internal
optics, a Laser DC power too low fault will result.
2. Turn off the sample valve at the tap in accordance with site lock-out, tag-out
rules.
3. Disconnect the gas sampling line from the sample supply port of the ana-
lyzer.
4. Wash the sampling line with isopropyl alcohol or acetone and blow dry with
mild pressure from a dry air or nitrogen source.
5. Once the sampling line is completely free of solvent, reconnect the gas sam-
pling line to the sample supply port of the analyzer.
6. Check all connections for gas leaks. SpectraSensors recommends using a liq-
uid leak detector.
To clean the J22 TDLAS Gas Analyzer exterior
The housing should be cleaned only with a moist cloth to avoid electrostatic
discharge.
Never use vinyl acetate, acetone or other organic solvents to clean the
analyzer housing or labels.
Spare Parts All parts required for operation of the J22 TDLAS Gas Analyzer must be supplied
by SpectraSensors or an authorized agent (→ 137).
Troubleshooting/
Repairs
Any repairs carried out by the customer or on behalf of the customer must be
recorded in a site dossier and kept available for inspectors.
Replacing the membrane separator filter
1. Close the sample supply valve.
2. Unscrew the cap from the membrane separator.
If the membrane filter is dry:
3. Check if there are any contaminants or discoloring of the white membrane. If
yes, the filter should be replaced.
4. Remove the O-ring and replace the membrane filter.
5. Replace the O-ring on top of the membrane filter.
6. Place the cap back onto the membrane separator and tighten.
7. Check upstream of the membrane for liquid contamination and clean and dry
out before re-opening the sample supply valve.
