This section outlines the space and resource requirements for
GC and automatic liquid sampler (ALS) installation. For a
successful and timely installation of the instrument, the site
must meet these requirements before beginning installation.
Necessary supplies (gases, tubing, operating supplies,
consumables, and other usage-dependent items such as
columns, vials, syringes, and solvents) must also be available.
Note that performance verification requires the use of helium
carrier gas. Refer to the Agilent Web site at
www.agilent.com/chem for the most up-to-date listing of GC and
ALS supplies and consumables.
If you require any additional clarification on the requirements
described in this manual, please visit the Agilent web site at
www.chem.agilent.com, or contact your Agilent sales
representative.

Customer Responsibilities
The specifications in this manual outline the necessary space,
electrical outlets, gases, tubing, operating supplies,
consumables, and other usage-dependent items such as
columns, vials, syringes, and solvents required for the
successful installation of instruments and systems.
If Agilent is delivering installation and familiarization services,
users of the instrument should be present throughout these
services; otherwise, they will miss important operational,
maintenance, and safety information.
If Agilent is delivering installation and familiarization services,
delays due to inadequate site preparation could cause loss of
instrument use during the warranty period. In extreme cases,
Agilent Technologies may ask to be reimbursed for the
additional time required to complete the installation. Agilent
Technologies provides service during the warranty period and
under maintenance agreements only if the specified site
requirements are met.
Before contacting Agilent to arrange for installation of your new
GC, you must complete the Site Readiness Certification found in
Appendix A, “Site Preparation Readiness.”
Site Preparation Good Practices
If you are not already familiar with Agilent instruments or with
gas chromatography, prepare for the installation and
familiarization service by doing the following:
•Visit the Agilent web site at www. agilent.com/chem, and
view the 7820A GC information available there.
•Attend one of the Agilent e-Seminars or training classes.
Agilent also provides a variety of training options, from
online training to on-site classes.
Having a basic knowledge of the instrument will enhance any
the familiarization services.

Agilent Technologies Installation and Familiarization Services
If you purchased installation and familiarization services from
Agilent, these services include:
•Installation of the GC
•Installation of purchased Agilent software
•Agilent chemical test to verify GC function
•Several hours of GC familiarization training for 2 operators.
Some additional software training time is provided if you
have purchased an Agilent software bundle.
The basic installation and familiarization services do NOT
include tasks such as:
•Network setup of instruments or computers to the site
network
•Customizations
•Method or application setup, development, or testing
•Analysis of customer standards or samples
•Site preparation (such installation of gas cylinders, tubing,
traps, electrical supplies, or clearing of suitable bench space)
•Familiarization or installation of nonAgilent software
To arrange for additional services, including training or
application development, contact your Agilent sales
representative or visit the Agilent web site at
www.agilent.com/chem.

Computer Requirements
A computer is required for 7820A GC installation and
operation. The computer must meet the minimum requirements
to run the Agilent Instrument Utility. Table 1 lists these
requirements for version B.01.01 of the Instrument Utility.
Agilent also provides a free utility that can verify if your
computer meets the requirements for a selected Agilent
software product. To download the tool, go to the Agilent web
site at www.agilent.com/chem, then search for “PC Utility.”

Dimensions and Weight
Select the laboratory bench space before the system arrives. Pay
special attention to the total height requirements. Avoid bench
space with overhanging shelves. See Table 2.
The instrument needs space for proper convection of heat and
ventilation. Allow at least 25 cm (10 in) clearance between back
of the instrument and wall to dissipate hot air.
A simple 7820A system that includes a GC, ALS injector, and a
computer would require about 111 cm (3 ft 8 in.) of bench
space. Allowing for operational access and a printer, a total of
153 cm (5 ft) of bench space should be available for a full GC
system. Some repairs to the GC will also require access to the
back of the instrument.

Product Height Width Depth Weight
7820A GC 49 cm (19.5 in) 56 cm (22 in) 51 cm (20.5 in) 50 kg (110 lb)
Additional space requirements
•Typical laser printer Requires 41 cm (16 in)
•GC operational oven access Requires ≥30 cm (12 in) open space above GC
•GC with 7693A ALS injector Requires 50 cm (19.5 in) above the GC

Power Consumption
Table 3 lists site power requirements.
•The number and type of electrical outlets depend on the size
and complexity of the system.
•Power consumption and requirements depend on the
country to which the unit ships. Find the instrument type
and your line voltage to find your instrument’s power
requirements.
•The electrical outlet for the unit should have a dedicated
ground. Voltage between ground and neutral should be less
than 2.5 VAC.
•The voltage requirements for your instrument are printed
near the power cord attachment.
Although your GC should arrive ready for operation in your
country, compare its voltage requirements with those listed in
Table 3. If the voltage option you ordered is not suitable for your
installation, contact Agilent Technologies.

WARNING
Do not use extension cords with Agilent instruments. Extension cords normally are
not rated to carry enough power and can be a safety hazard.
