PREFACE
We are grateful for your purchase of Hitachi ZA3000 Series
Polarized Zeeman Atomic Absorption Spectrophotometer.
The ZA3000 series atomic absorption spectrophotometer is an
instrument designed for elemental analysis.
This instrument is intended for use by persons having a
basic knowledge of chemical analysis. Analysis with this
instrument always requires the presence of an analyst
because it involves combustion of a flame or heating of the
atomizing furnace. Remember that improper use of the
analytical instruments, chemicals or samples would result
not only in wrong analytical data but also in consequences
adverse to safety such as personal injury.

SAFETY SUMMARY
General Safety Guidelines
Precautions before Use
Before using the instrument, be sure to read this manual
carefully until you fully understand its contents.
Keep this manual in a safety place nearby so that it can be
referred to whenever needed.
Operate the instrument in the procedure given in this manual.
Be sure to understand and observe the safety instructions
given in this manual.
Be sure to observe the cautions indicated on the instrument
and in the manual. If this is neglected, personal injury or
instrument damage may be caused.
Be sure to follow the original usage of the product and the
usage specified in this manual.
Never attempt modification of the instrument, use of a part
other than specified and instrument operation with safety
devices released, because they are dangerous.
Do not perform operations other than those described in the
instruction manual. If any problem occurs on the instrument,
contact our sales representative or service office.
In analysis with the atomic absorption spectrophotometer,
flame ignition or graphite furnace heating is performed.
Be sure to carry out analysis in the presence of the analyst.
Unattended operation is prohibited.
When using chemicals for analytical operation, be sure to
provide proper ventilation of the laboratory room per local
requirements. Inadequate ventilation could endanger human
health.

SAFETY - 3
SAFETY SUMMARY
General Safety Guidelines (Continued)
Keep in mind that the hazard warnings in this manual and on
the instrument cannot cover every possible case, as it is
impossible to predict and evaluate all circumstances
beforehand. Therefore, just following the given directions
may be inadequate for operation. Be alert and use your
common sense.
Be sure to observe the above precautions strictly.
Otherwise, not only may correct analytical results be
unobtainable, but also personal injury may be caused.
Precautions on Use
In analysis with the atomic absorption spectrophotometer,
flame ignition or atomizer furnace heating is performed.
A fire or explosion may be caused if operation is carried on in
an abnormal condition such as abnormal sound, abnormal
odor, smoke or gas leak.
Be sure to carry out analysis in the presence of the analyst.
Avoid unattended operation.
If an abnormal condition such as abnormal sound, abnormal
odor, smoke or gas leak occurs, immediately turn off the
power supply, close the main valve of the gas cylinder and
take necessary safety measures. After that, contact our
service office.

Precautions on Installation, Maintenance and Relocation
The customer shall not attempt initial installation (upon
delivery) of the instrument.
For safe and exact use of the instrument, service personnel
trained and approved by us will carry out the installation.
Upon completion of installation, check if all the standard
accessories have been supplied.
Lack of a standard accessory or accessories may cause the
instrument to malfunction and compromise the safety.
If anything is missing or damaged or you have any question,
consult with the installer, or our sales representative or service
office.
The contents of maintenance by the customer are restricted to
the items described in this manual. Before maintenance,
read the relevant instructions carefully. Never attempt
maintenance not described in the manual. Failure to do so
could cause malfunction of the instrument or personal injury.
Avoid moving the instrument after installation. This might
result in deviation of the precisely adjusted optical system may
get out of order due to vibration, etc.
If a warning label is deteriorated due to secular change or
damaged, contact our service office.
Replace the life-limited parts of the instrument with new ones
at intervals specified in this manual. Otherwise, a failure
could occur to result in gas leak, water leak, electrical leak or
ignition. For other than the part replacement procedures to
be performed by the user as specified in this manual, refer
replacement servicing to the our sales representative or
service office.
When the instrument reached the end of its useful life, stop
using the instrument. Gas leak, water leak, electrical leak or
ignition may be caused if the instrument is used beyond the
useful life.

SAFETY - 5
SAFETY SUMMARY
Warning Indications in this Manual
Warning indications described in this manual and their locations
in it are listed below.
List of DANGER Indications
Malfunction of Pacemaker!
There is a danger of faulty operation of a pacemaker due to
the strong magnetic field produced.
A person who uses a pacemaker should not come within 1
meter of the instrument, or should avoid handling the
instrument altogether. (Sections 3 and 5 in this manual)

SAFETY - 6
SAFETY SUMMARY
List of WARNING Indications
Beware of High Voltage!
There is a danger of electric shock due to high voltage of
about 400 V. Touching the socket of the hollow cathode
lamp could result in fatal or serious injury.
Before replacing the lamp, be sure to turn OFF the lamp
current (click the lamp OFF button). (Section 1 in this manual)
Beware of Toxic Gas!
Inhalation of toxic gas could be injurious to human health.
Inhaling the vapor emitted from the sample may cause
inflammation of the respiratory tract.
Be sure to operate the ventilating fan to discharge the vapor
emitted from the sample through the exhaust duct.
(Sections 1, 3 and 5 in this manual)
Explosion due to Backfiring!
If water is not supplied to the drain trap, there is a danger of
explosion due to backfiring, or ignition due to gas leakage.
Be sure to supply the drain trap with water.
(Sections 1 and 5 in this manual)
Explosion due to Acetylide Formation!
If samples containing a large amount of copper, silver or
mercury are atomized, it may generate metal acetylide and
cause explosion due to backfiring with louse noise. Do not
measure samples containing a large amount of copper,
silver or mercury.
(Quoted from JIS K 0120 General rules for
atomic absorption spectrometry)

SAFETY - 7
SAFETY SUMMARY
List of WARNING Indications (Continued)
Explosion due to Perchloric Acid!
If metals (copper, silver and mercury) that form metal
acetylide and perchloric acid are contained in a sample
when using a high-temperature burner, they react in the
flame chamber and may result into explosions with loud
noise due to backfiring.
Do not measure samples containing metals that form metal
acetylide and perchloric acid when using a
high-temperature burner.
