Operating Instructions J22 TDLAS Gas Analyzer
106 Hauser
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/tagout 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.
10.1 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 membrane if necessary. If liquid enters the cell and accumulates on the internal
optics, a DC spectrum power range exceeded fault will result.
2.
Turn off the sample valve at the tap in accordance with site lockout, tagout rules.
3.
Disconnect the gas sampling line from the sample supply port of the analyzer.
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 sampling line to the sample supply port of
the analyzer.
6.
Check all connections for gas leaks. Using a liquid leak detector is recommended.
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.
10.2 Spare parts
All parts required for operation of the J22 TDLAS Gas Analyzer must be supplied by Hauser or an authorized
agent →  .
10.3 Troubleshooting/repairs
Make sure that a membrane separator filter is operating normally. If liquid enters the cell and accumulates on the
internal optics, a DC spectrum power range exceeded fault will result.
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.
10.3.1 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.
If liquid or contaminants are detected on the filter:
3.
Drain any liquids and clean with isopropyl alcohol.
