Toconnectthepneumaticvalvesource(ifapplicable)
1. Determine appropriate tubing route from the customer supplied
instrument air or nitrogen control gas source (3.4 barg [50 PSIG]
minimum to 6.9 barg [100 PSIG] maximum) to the SCS.
2. Run stainless steel tubing from the customer supplied regulator
(3.4 barg [50 PSIG] minimum to 6.9 barg [100 PSIG] maximum) to
the pneumatic valve instrument air supply port.
3. Bend tubing using industrial grade benders, check tubing fit to
ensure proper seating between the tubing and fittings.
4. 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.
5. Connect the control gas tube to the SCS using the 1/4 in. stainless
steel compression-type union fitting provided.
6. Tighten all new fittings 1-1/4 turns with a wrench from finger tight.
a. 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.
7. Check all connections for gas leaks. SpectraSensors recommends
using a liquid leak detector.
Connecting the Validation Gas Source (if
Applicable)
For systems with validation, an appropriate validation gas source will need to
be connected to the SCS.
Toconnectthevalidationsource
1. Determine appropriate tubing route from the customer supplied
validation gas source to the SCS.
2. Run stainless steel tubing from the validation source (regulated to
the specified pressure) to the validation gas supply port.
3. Bend tubing using industrial grade benders, check tubing fit to
ensure proper seating between the tubing and fittings.
4. 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.
Do not exceed 0.7 barg (10 PSIG) in sample cell. Damage to cell
may result.
