4.7 Gas connections
Once you have verified that the J22 TDLAS Gas Analyzer is functional and that the analyzer circuit is de-energized,
you are ready to connect the sample supply, sample purge, pressure relief vent (if applicable), validation source (if
applicable) and purge supply (if applicable) gas lines. All work must be performed by technicians qualified in
pneumatic tubing.
Process samples may contain hazardous material in potentially flammable or toxic concentrations.

Personnel should have a thorough knowledge and understanding of the physical properties and safety
precautions for the sample contents before installing the sample system.

Do not exceed 0.7 barg (10 psig) in the sample cell. Damage to cell may result.
Using electropolished 6 mm or ¼ in. (depending on order options) O.D. seamless stainless steel tubing is
recommended. For supply and return port locations, refer to technical drawings →  .
Connecting the sample supply line
1.
Before connecting the sample supply line, confirm the following:
a. The sample probe is correctly installed at the process sample tap and that the sample probe isolation valve is
closed.
b. The field pressure reducing station is installed properly at the sample probe and that the pressure regulator at
the field pressure reducing station is closed (adjustment knob turned fully counterclockwise).
The process sample at the sample tap may be at high pressure.

Use extreme caution when operating the sample probe isolation valve and field pressure reducing pressure
regulator.

All valves, regulators, switches, etc. should be operated in accordance with site lockout/tagout procedures.

Consult sample probe manufacturer instructions for proper installation procedures.
