Label Wire color
Ground (G) Green with yellow tracer or green
2. Bring the power leads in through the left entry on the bottom of the enclosure.
3. If necessary at remote locations, connect the GC chassis ground wire to an external
copper ground rod.
See Grounding precautions regarding electrical and signal grounding.
2.4.3 Connect gas lines
Procedure
1. Remove the plug from the 1/16 in. sample vent tubing marked SV1 that is located
on the flow panel assembly.
• If desired, connect the sample vent lines to an external, ambient pressure vent. If
the vent line is terminated in an area exposed to wind, protect the exposed vent
with a metal shield.
• Use ¼-in. or ⅜-in. tubing for vent lines longer than 10 ft. (3 m).
At this stage in the installation, the measure vent (MV) lines (labeled on the side of
the gas chromatograph [GC]) should remain plugged until the GC has been checked
for leaks. For regular operation, however, the MV lines must be unplugged.
Note
Do not discard the vent line plugs. They are useful when leak-checking the GC and
its sample or gas line connections.
2. Connect the carrier gas to the GC. The carrier gas inlet is labeled Carrier In and is a
¼-in. T-fitting.
WARNING
EXPLOSION HAZARD
Failure to follow this warning may result in injury or death to personnel.
Do not turn on sample gas until you have completely checked the carrier lines for
leaks.
• Use stainless steel tubing to convey carrier gas.
• Use a dual-stage regulator with high-side capacity of 3,000 psig (20,684.3 kPa)
and low-side capacity of 150 psig (1,034.2 kPa).
• Carrier gas is fed from two bottles (see Carrier gas installation and maintenance)
for carrier gas plumbing.
3. Connect calibration standard gas to the GC.
When installing the calibration standard gas line, ensure that the correct tubing
connection is made.
