III

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

making necessary arrangement to prevent an accidental ignition

(firing) by static electricity.

If the fuse is kept blown off after being replaced, power off
the detector immediately and disconnect the power cord.
Please consult out local representative in your area
or SHOKO SCIENCE.

Use only the following power supply cord.

Using the wrong

power cord could result in danger or fire.
The protection ClassⅠ equipment should be connected to PE
(protective earth) terminal.

External input/output are for contact closure.

Never apply voltage to those.

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 exist.

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.

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 of high concentration,

make sure that the flow line is washed with water thoroughly

after use. Failure to do so may result in the plugging of the
line causing the detector to cease operation.

If the detector is not to be used for more than one week, then,

prior to storage, wash the flow line with pure water or acetone,

and dry the line by allowing nitrogen gas to flow through.
