1. Confirm that the low pressure flare or atmospheric vent header shut-
off valve is closed.
2. Determine appropriate tubing route from the SCS to the low
pressure flare or atmospheric vent header.
3. Run stainless steel tubing from the sample return ports to the low
pressure flare or atmospheric vent header connection. Bend tubing
using industrial grade benders, check tubing fit to ensure proper
seating between the tubing and fittings. Fully ream all tubing ends.
Blow out the lines for 10 to 15 seconds with clean, dry nitrogen or
air prior to making the connection.
4. Connect the sample/bypass return tube to the SCS using the 1/4 in.
stainless steel compression-type fittings provided.
5. Tighten all new 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.
6. Check all connections for gas leaks. SpectraSensors recommends
using a liquid leak detector.
7. Be sure to vent any pressure relief vent ports (if applicable) and/or
DBB valve vent ports (if applicable) in a similar fashion when the unit
is in use.
Do not exceed 0.7 barg (10 PSIG) in sample cell. Damage to cell
may result.
All valves, regulators, switches, etc. should be operated in
accordance with site lock-out/tag-out procedures.
Do not exceed 0.7 barg (10 PSIG) in sample cell. Damage to cell
