About Maintenance
Maintenance must be performed periodically to ensure that the static elimination performance of the SJ-
F100W/100/010 is fully demonstrated. Maintenance should thoroughly read the descriptions under
"Safety Precautions" (page i), and perform maintenance paying attention to the following points.
About Maintenance
When the SJ-F100W/100/010 is used for a long period of time, the electrode needles become dirty due
to the adhesion of dust and dirt.
If the ion level alarm indicator lights, clean the electrode needles. If the electrode needles are used in a
dirty or dusty state, the static elimination performance can no longer be fully demonstrated, resulting in
accidents or malfunction. We recommend periodically cleaning the electrode needles (as a guideline,
once every two weeks in a regular operating environment though this depends on the installation
conditions).
If cleaning the electrode needles does not improve the static elimination performance, or the ion level
alarm indicator frequently lights, replace the Electrode Unit.
• The SJ-F100W/100/010 uses high voltage. Before starting maintenance, be
sure to turn the power OFF. Failure to do so might result in electric shock or
malfunction.
• Do not directly touch the electrode needles. Take care not to touch these
needles even if the power is turned OFF. Directly touching these needles may
cause personal injury.
