General
Operation of an Agilent 4107 Nitrogen Generator involves the use of
compressed gases. Careless, improper or unskilled use of this
nitrogen generator can cause death or serious injury to personnel,
and/or severe damage to equipment and property.
The nitrogen generator covers are designed to prevent inadvertent
contact with any potential hazards. If the nitrogen generator is used
in any manner not specified by Agilent, this protection may be
impaired.
The safety practices described below are provided to help the user
operate the nitrogen generator safely. Read each safety topic
thoroughly before attempting to operate the nitrogen generator and
always operate the nitrogen generator in accordance with these
safety practices.

Safety Practices and Hazards

If you are unsure of the effects of any liquid, gas or chemical on the
nitrogen generator, consult your Agilent field service engineer or
approved representative before use.
Air supply
To avoid shortening its life, the nitrogen generator requires a supply
of clean, dry, oil-free air. To assist in achieving this, the nitrogen
generator has integral filters attached to the side of the unit.
Depending on the quality of the air supply and the environmental
conditions, additional driers and filters may be required. Please refer
to the Agilent MP-AES Site Preparation Guide for further details and
read the instructions regarding filters under the Maintenance chapter
of this guide.
CAUTION Under no circumstances should the nitrogen generator be operated without
these filters connected or with the filters in a saturated condition.
CAUTION Under no circumstances should the nitrogen generator be connected to an air
supply containing oil. Permanent damage to the nitrogen generator will occur.
Contamination of the sorbent material with oil will invalidate the
warranty.
Compressed Gas Hazards
Air compressors must be located and connected strictly in
accordance with local safety codes and regulations.
All compressed gases (other than air) can create a hazard if they leak
into the atmosphere. Even small leaks in gas supply systems can be
dangerous. Any leak (except that of air) can result in an oxygen-
deficient atmosphere which can cause asphyxiation. The area in
which cylinders are stored and the area surrounding the instrument
must be adequately ventilated to prevent such gas accumulations. Do
not directly inhale the output gas from the nitrogen generator.

Safety Practices and Hazards
Agilent 4107 Nitrogen Generator User’s Guide 7
Periodically inspect the hoses to make sure they are in good
condition and properly connected. Keep air hoses off the floor where
they can be tripping hazards or become damaged. When
disconnecting or connecting the hoses, make sure the hose is
depressurized first.
Always wear safety glasses when connecting or disconnecting gas
lines.
Electrical Hazards
Panels or covers which are retained by screws on the nitrogen
generator may be opened only by Agilenttrained, Agilent-qualified or
Agilentapproved field service engineers (unless specified otherwise).
The nitrogen generator is powered by an external AC-DC power
supply. If the enclosure of this power supply is damaged it should be
replaced immediately. Check the power cord for damage and replace
it if it is visibly worn or damaged.
If necessary, replace the power cord only with a cord equivalent to
the one specified in the site preparation guide.
Compressor
Consult the manuals or product labels supplied with your air
compressor for safety information and to determine which parts of it
are operator-accessible.
Other Precautions
The nitrogen generator weighs approximately 110 kg (242.5 lb). To
avoid injury to personnel or damage to the instrument or property,
always use a suitable mechanical lifting device to move the nitrogen
generator.
Use only Agilent-supplied spares with your nitrogen generator.

Electromagnetic Compatibility
EN55011/CISPR11
Group 1 ISM equipment: group 1 contains all ISM equipment in
which there is intentionally generated and/or used conductively
coupled radio- frequency energy which is necessary for the internal
functioning of the equipment itself.
Class A equipment is equipment suitable for use in all
establishments other than domestic and those directly connected to a
low voltage power supply network which supplies buildings used for
domestic purposes.
This device complies with the requirements of CISPR11, Group 1,
Class A as radiation professional equipment. Therefore, there may be
potential difficulties in ensuring electromagnetic compatibility in
other environments, due to conducted as well as radiated
disturbances.
Operation is subject to the following two conditions:
1This device may not cause harmful interference.
2This device must accept any interference received, including
interference that may cause undesired operation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try one or more of
the following measures:
1Relocate the radio or antenna.
2Move the device away from the radio or television.
3Plug the device into a different electrical outlet, so that the device
and the radio or television are on separate electrical circuits.
4Make sure that all peripheral devices are also certified.
5Make sure that appropriate cables are used to connect the device
to peripheral equipment.
6Consult your equipment dealer, Agilent Technologies, or an
experienced technician for assistance.
