*Install the unit onto a frame or similar structure of adequate
strength. if the strength is insu󰀩cient, the unit may become
unstable and fall, or may cause bending of the body.
*Be sure to check the installation location and other conditions
before installing the unit. In particular, if there are problems such as
vibration or level di󰀨erences at the installation location, bending of
the unit may occur, resulting in malfunction.
*Be sure to turn the power OFF before installing the unit. High
voltage is applied to the emitter needle. If ngers, tools, jewelry, or
other conductive objects are brought close to the needle, electrical
shock or malfunction may occur.
*Before installing the unit, verify that there is no looseness of the
emitter needle nozzle. If the nozzle is loose, it may fall o󰀨 during
installation or, during operation when the power is turned ON.
*If there are any structural objects between the unit installation
position and target for electrostatic eliminiation, the ions in
the emitted air may be depleted, preventing the full ectrostatic
elimination e󰀨ects from being achieved. Select a unit installation
position so that no objects can interfere with the operation. Please
be careful not to omit some structural objects moving nearby, when
installing.
*The distance of the ground point from the target for electrostatic
elimination is 50mm-1500mm. The electrostatic elimination e󰀨ects
are optimum at a distance of 50mm. As the distance increases,
the e󰀨ects decrease and a longer amount of time may be required
for electrostatic elimination. Please conrm the elimination e󰀨ect
beforehand.
