Installing the GC 1
Agilent 7890B Installation 13
Step 1. Place the GC on the bench
The GC requires a bench that can support its weight plus that of
other equipment you will use with it. The area must be free of
overhanging obstructions that might interfere with
autosamplers, or that limit access to the top of the instrument.
The area must include sufficient space behind the GC to allow
for cooling.
1 Remove the GC from its shipping box.
2 Place the GC on the bench top. Make sure gas and power
supplies are accessible. Place related equipment near the GC.
3 If space is limited behind the GC, attach the optional oven
exhaust deflector to the back of the GC as shown below.
(Order Option 306 or part number G1530-80650.) The
deflector hangs from the exhaust vents on four hooks.
Figure 3 Correct position of the oven exhaust deflector
The oven exhaust deflector accepts a 10-cm (4 in.) diameter
exhaust duct, and adds about 13 cm to the depth of the GC.
Be careful when lifting the GC. Because it is heavy, two people
should lift it. When moving the GC, be aware that the back is
heavier than the front.
