Precautions
Thank you for your continued patronage. Observe the following precautions
in order to make safe and stable use of the detector.
Precautions are divided into three groups in this operation manual,
depending on the degree of danger. The three groups are
: This sign is used where failure to follow strictly the instructions
and procedures indicated by this sign may cause injury or
damage to health.
: This sign is used where failure to follow strictly the instructions
and procedures indicated by this sign may cause this detector
and the peripheral apparatus to deteriorate or break down.
: This sign is used wherever information is given to ensure optimal
performance of the detector.
Precautions listed below are those of particular importance extracted
from
this operation manual :
Do not use the detector in places where combustible gas or any
source of fire or spark exists or might exist.
Prior to connection, make sure that the voltage of the power
socket into which the detector power cable is plugged is the
same as the power supply voltage indicated on the detector.
The power socket into which the detector power cable is
plugged should be of a 3P type with a grounding terminal.
Other types of power sockets should not be used.
When using organic solvent, wear safety goggles.
It is recommended that a sink or equipment for washing the eyes
be installed nearby in case the organic solvent in use comes into
contact with the eye(s) or skin.
When any abnormality, such as liquid leakage, is observed, immediately
turn off the power and unplug the detector from the main power
source.

Warning
Do not use the detector with the cover open; always unplug the
detector from the main power source before opening the cover.
If the detector is used in a manner not specified by this operation
manual, the protection provided by the detector may be impaired.
When using flammable organic solvent as mobile phase, be sure
to make necessary arrangement to prevent accidental ignition
(fire) by static electricity.
If the fuse blows after being replaced, power off the detector
immediately and disconnect the power cord. Please consult
our local representative in your area or SHOKO SCIENTIFIC.
As this detector is readily affected by the ambient temperature, use
it in places where there is little wind or change in the ambient
temperature. Do not use the detector near any source of vibration,
electrical noise, or in places where corrosive gas and a lot of dust
are present.
External input/output terminals are for contact closure.
Never apply voltage to them.
Do not connect any tube other than the provided "OUT tube"
to the eluent outlet joint of the detector. Put the exit end of
the "OUT tube" in the waste liquid bottle and do not apply back
pressure.
When connecting this detector to other detectors in series, put
it at the end.
Make sure that no back pressure is applied to the outlet of the
detector. Connect the tip of the Teflon tube on the cell outlet of the
detector to a receptacle for waste liquid.
If eluent freezes inside the detector, the flow line might break,
damaging the detector. If there is any chance of eluent freezing
during stoppage or storage of the detector, withdraw the eluent
completely from the flow line of the detector.
When using any eluent containing a salt at high concentration, make
sure that the flow line is washed with water thoroughly after use
.
Failure to do so may result in plugging of the line, causing the
detector to cease operation.
If the detector is not to be used for more than one week, prior
to storage, wash the flow line with pure water or acetone, and dry
the line by allowing nitrogen gas to flow through it.
Do not use any eluent which might corrode the material, such as
stainless steel, that it comes into contact with. Use of such eluent
might cause a base line drift and damage the detector.

Caution
Use a thoroughly degassed eluent. It is recommended that a degassing
device be used to degas the eluent, as it is easy to use and permits
continuous degassing.
If an eluent is replaced with another eluent, replace all channels of the ion
chromatograph with new eluent. When eluent replacement is not sufficient,
it may become the cause of an unstabilized baseline.
When high voltage caused by static electricity is applied to the instrument,
some incorrect actions may be observed. Please take note of static
electricity.
Please do not set other equipment on this detector, in order to avoid
enlarging the baseline drift and losing control of the temperature.
