WARNING Do not place temperature-sensitive items (for example, gas cylinders,
chemicals, regulators, and plastic tubing) in the path of the heated exhaust.
These items will be damaged and plastic tubing will melt. Be careful when
working behind the instrument during cool-down cycles to avoid burns from
the hot exhaust.
If space is limited, the Oven Exhaust Deflector (part no. 19247-60510) may
improve oven cooling. It diverts exhaust air up and away from the instrument.
You can connect it to a 10.2-cm (4-inch) exhaust-duct system, route the
exhaust to a fume hood, or vent the exhaust outside the building with 10.2-
cm diameter (4-inch diameter) furnace duct.
Venting toxic or noxious gases
During normal operation of the GC with many detectors and inlets, some of
the carrier gas and sample vents outside the instrument. If any sample
components are toxic or noxious, or if hydrogen is used as the carrier gas, the
exhaust must be vented to a fume hood. Place the GC in the hood or attach a
large diameter venting tube to the outlet for proper ventilation.
To further prevent contamination from noxious gases, you can attach a
chemical trap (part no. G1544-60610) to the split vent.
Benchtop space requirements
The GC with electronic pneumatics control (EPC) is 59 cm (23 inches) wide.
The nonEPC model is 68 cm (26.7 inches) wide. Both are 50 cm (21 inches)
high and 50 cm (21 inches) deep.
The area above the GC should be clear, with no shelves or overhanging
obstructions that limit access to the top of the instrument and interfere with
cooling. You may need additional space for other instruments used with your
GC. Figure 510-1 shows some common system configurations.
Table 510-1 presents the dimensions, power requirements, heat production,
and weight of the GC and other Agilent instruments often used with it. Use
this table to insure that you have adequate space and power for the entire
