Warning
This product is not specified as an explosion-proof type unit. Do not use this unit at a
location or an atmosphere, in which combustible gas or solvent is handled, or else
ignition or explosion may occur.
A high voltage is applied to the Discharge Needle. Do not allow any conductive
material, including your finger, any part of your body, wire or any tool to get close to the
Needle, or an electrical shock accident or a malfunction of the unit may occur.
The Discharge Needle has a sharp edge. Pay special attention to handling of the
Needle, or you may injure yourself.
Make sure that the ground terminal of this product is properly grounded to prevent any
electric shock accident from occurring and to ensure that the static electricity is
completely eliminated.
Do not use this unit outside the scope of the specifications, or else an accident or a
malfunction of the unit may be caused, or the service life of the product may be
extremely reduced.
Never disassemble, repair, or remodel this unit, or else an accident or a malfunction of
the unit may occur.
This product will cause ozone to be generated in the atmosphere. If you perceive any
smell of ozone, make sure to clear the air in the room and keep good ventilation in the
room. If ozone should remain in the air for long, it may cause metal parts to be
oxidized.
When any wiring, installation, or inspection work is to be carried out, make sure that the
unit is disconnected from the power supply, or else an accident, an electrical shock or a
malfunction may be caused.
To ensure that the unit should maintain its performance, be sure to regularly clean the
surrounding area of the discharge area. If the area is not maintained in a clean
condition, the unit will not only be able to demonstrate the optimum performance but
the equipment and or work pieces may get damaged.
For any other items of warning, please refer to the Safety Precaution in the Static

Caution
Do not install or use the product on the surface of any device that contains on moving
part, where it may be subjected to violation or shocks. The product may possibly be
damaged.
The product is not specified to be installed in any specific orientation. Make sure,
however, that the surface on which the product should be installed is perfectly level and
not inclined in any direction.
Provide a space of 30 mm or more in front of the air inlet of the product, whether
Product is to be installed. If any obstacle for air intake exists near the air inlet, the
sufficient amount of air will not be supplied to the unit, preventing the product from
operating up to its full performance.
Do not install the product at the location where dew condensation may occur or where
it may be exposed to extremes of temperatures and/or humidity. It is possible that the
product should get damaged.
(1) The product may be used by placing it on a horizontal surface such as a tabletop.
When installing the unit as a component etc. inside a system, fasten the unit on the
system by using M4 screws (including spring washers and washers) on the mounting
holes (6-φ4.5).
