20.
• The maintenance and checkup procedures to be taken by the user are only those described
in the manual. When taking the maintenance and checkup procedures described in the
manual, attain a clear understanding of them.
• Do not perform other maintenance and checkup procedures to avoid jeopardizing safety

could result in personal injury to yourself or other persons. Be
sure that all instrument operators read and understand the
precautions listed below. It is advisable to post a copy of the
WARNING
precautions near or on the instrument shelf.

Ignition of Flammable Chemicals

• This instrument is not explosion-proof. In unattended operation, do not use organic
solvents having an ignition point below 70 °C.
• Beware of ignition hazard when using flammable chemicals such as organic solvents.
a. Do not bring a heat or flame source near the instrument.
b. Well-ventilate the laboratory room where the instrument is used.
c. Always check the following conditions. If an abnormality is found, stop operation
immediately and unplug the power cord from the supply.
Leakage of solvent or waste solution.
Leakage of solvent inside the instrument.
•
When using flammable chemicals, be careful about possible ignition due to static electricity.
To prevent the build-up of static electricity, use a conductive container for waste solution
and provide proper grounding connection to it.

Explosion of Vapor from Flammable Chemicals

If a flammable chemical such as organic solvent leaks from the flow path of the instrument and its
vapor concentration reaches the explosion limit, it could cause spontaneous combustion with
dangerously explosive results.
When using a flammable and readily volatile chemical, be sure to check for leakage from the
instrument flow path and ventilate the laboratory room adequately.
