Connections to the Gas Supply
Use the following procedure to connect the sample supply line. All work must
be performed by technicians qualified in instrument tubing.
To connect the sample supply line
1. First, confirm that the sample probe is correctly installed at the process
supply tap and that the sample probe isolation valve is closed.
2. Also confirm that the field pressure reducing station is installed prop -
erly at the sample probe and that the pressure regulator at the field
pressure reducing station is closed (adjustment knob turned fully
counter-clockwise).
3. Check that the relief valve vent line is properly installed from the field
pressure reducing station to the low pressure flare or atmospheric vent
connection.
4. Determine appropriate tubing route from the field pressure reducing
station to the SCS.
5. Run stainless steel tubing from the field pressure reducing station 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
to
15
seconds with clean, dry nitrogen or air prior to making the connection.
6. Connect the inlet tube to the SCS using the 1/4 in. stainless steel com -
pression-type fitting provided.
7. 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.
Because the breaker in the customer-provided power
distribution panel or switch will be the primary means of
disconnecting the power from the analyzer, Hauser
recommends that the power distribution panel be located in
close proximity to the equipment.
Thread lubricant must be applied on all conduit hub threaded
connections. Hauser recommends using STL8
lubricant on all conduit screw thread and its taped openings.
The process sample at the sample tap may be at a high
pressure. Use extreme caution when operating the sample
probe isolation valve and field pressure reducing regulator.
All valves, regulators, switches, etc. should be operated in
accordance with site lock-out/tag-out procedures.
