6. Run stainless steel tubing from the field pressure reducing station
(set for the specified inlet pressure) to the sample supply port of the
SCS. 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
–15 seconds with clean, dry
nitrogen or air prior to making the connection.
7. Connect the inlet tube to the SCS using the 1/4” stainless steel
compression-type fitting provided.
8. 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.
9. Check all connections for gas leaks. SpectraSensors recommends
using a liquid leak detector.
