1Installing the GC
Overview of Installation
Purpose of this procedure
This procedure ensures that instruments and systems are
installed and functioning as designed. Correct installation is the
first step in ensuring that instruments and systems operate
reliably over their lifetime.
Customer responsibilities
1Make sure your site meets the basic requirements, including
the necessary space, electrical outlets, gases, tubing,
operating supplies, consumables and other usage-dependent
items required for a successful installation. Refer to the
Agilent GC, GC/MS, and ALS Site Preparation Guide.
2If Agilent is delivering installation and familiarization
services, users of the instrument should be present
throughout these services; otherwise, these users will miss
important operational, maintenance, and safety information.
Additional information is included with the Agilent GC and
GC/MS User Manuals & Tools DVD.
If your site complies with all site preparation specifications, the
average installation time for the GC is about 2 hours. Allow
more time for any additional products (for example, an ALS),
add-ons, and software.

contains a listing of Agilent installation kits and a description of
parts included with each. These kits contain filters, fittings,
tubing, tools (wrenches, tubing cutter, drivers, and so on), and
other required parts for installing a GC.)
Performing checkout
Checkout requires a system that can produce a chromatogram.
•If using an Agilent data system, you can use it to perform the
checkout procedure. Read these GC installation instructions
and the instructions for installing the data system.
•If an Agilent data system is not available, you can also
perform checkout using the Agilent Instrument Utilities
software. Install the software on a PC, then read its help
topics to learn how to connect to the GC and how to launch
the checkout procedures.
•If connected only to an integrator or site system (for
example, a LIMS system) that captures the GC output signal,
you must connect to that system to obtain the
chromatogram.
System installation
If installing an ALS, the ALS can be used for checkout. Also

10 Agilent 7890B Installation
1Installing the GC
refer to the ALS installation documentation.
When installed as part of a complete system including an
Agilent data system (for example, Agilent OpenLAB CDS), first
install the GC through the checkout column bakeout step. Once
the bakeout ends, configure the new GC in the data system and
open the online instrument session. Use the data system to
perform the checkout test.
When installed as part of other complete systems, for example
in an Agilent GC/MSD or GC/MS system, see the installation
instructions for that system.

Unpacking
1Inspect the shipping containers for damage. If a container is
damaged or shows signs of stress, notify both the carrier and
your local Agilent sales office.
Keep all shipping materials for inspection by the carrier.
2Check the items received against the packing lists. If there
are discrepancies, notify your local Agilent sales office
immediately.
Keep the shipping containers until you have checked their
contents for completeness and verified instrument
performance.
3Remove caps and packing.
Some detectors may have protective caps for shipping.
Remove these caps. If equipped with a side-mounted
detector, remove the left side panel to gain access to the
detector vent cap.
Open the oven door. Remove any packing from inside the
oven.

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.
1Remove the GC from its shipping box.
2Place the GC on the bench top. Make sure gas and power
supplies are accessible. Place related equipment near the GC.
3If 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.
WARNING
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.

Step 2. Verify line voltage, voltage settings, and power cord.
1Locate the power label near the power cord connector on the
back of the GC. (See Figure 2.) Compare the instrument
power settings with the laboratory line voltage. See “Power
consumption” below.
2Verify that the power cord is correct for the voltage and
location. See “Power cords available” on page 15.
3Have a qualified person measure the actual power outlet
voltage and verify it meets the tolerance requirements listed
in Table 1 on page 15. See “Grounding” on page 19 and “Line
voltage” on page 19.
The next sections detail the power specifications and
requirements for reference.
Power consumption
The number and type of electrical outlets required for
installation depends on the size and complexity of your system.
A GC system with a computer, monitor, printer, and hub
requires 5 outlets. The outlet for the GC must have a dedicated
ground.
Each GC has a label next to the power cord connector that lists
its line voltage requirements. See the examples below.
The GC power consumption and requirements depend on the
type of oven that you ordered and the country the unit shipped
to. Fast oven options 002 and 003 require more power than the
standard oven.
WARNING
Electrical shock hazard. To avoid injury, only a qualified person
should measure line voltage.

Notes
1Some US labs have 4-wire service resulting in 208 V at the
wall receptacle. It is important for a qualified person to
measure the line voltage at the receptacle for the GC. Option
003, 208 V fast oven, uses a 220 V unit with operating range
of 193 to 231 V.
2Power line conditioners should not be used with the GC.

Grounding
To protect users, the metal instrument panels and cabinet are
grounded through the three-conductor power line cord in
accordance with International Electrotechnical Commission
(IEC) requirements.
The three-conductor power line cord, when plugged into a
properly grounded receptacle, grounds the instrument and
minimizes shock hazard. A properly grounded receptacle is one
that is connected to a suitable earth ground. Proper receptacle
grounding should be verified.
Make sure the GC is connected to a dedicated receptacle
(outlet).
Line voltage
The GC operates from one of the AC voltage supplies listed in
Table 1, depending on the standard voltage of the country from
which it was ordered.
GCs are designed to work with a specific voltage; make sure
your GC voltage option is appropriate for your laboratory. The
voltage requirements for your GC are printed near the power
cord connector.
Although your GC should arrive ready for operation in your
country, compare its voltage requirements with those listed in
Table 1. If the voltage option you ordered is not suitable for your
installation, contact Agilent Technologies.
Line power cord terminations
The power cord termination is determined by the country
where the GC is ordered.
