3. Installation and wiring
·
The performance of the product varies depending on the surrounding installation and operating conditions. It
is recommended to investigate in advance any processes and parts where static electricity disturbances
occur. Verify that the required conditions have been met in order to effectively remove static electricity before
installation.
·
After installation, verify the performance of this product.
3-1. Installation of Ionizer
3-1-1. Precautions for Installation
·
Be sure to stop power supply and air supply to the product before starting the product installation.
·
Do not affix any tape or labels to the bar. Dielectric phenomenon may occur due to ions arising from such
substances, resulting in electrostatic charging or electric leakage.
3-1-2. Adjustment of Pressure (Flow adjustment)
·
When air is supplied to the bar, adjust the flow using a regulator which should be connected immediately
before the bar. If a flow adjustment valve is used between the bar and regulator , the speed of the flow from
the nozzle decreases due to the pressure decrease , decreasing the neutralizing performance.
·
Check the pressure around the bar air supply port. A pressure difference may be generated between the
regulator pressure and the pressure at the bar air supply port due to the supply piping length and piping
diameter. If a pressure gauge with regulator is used for checking the pressure, use a large capacity
regulator, keep the piping as short as possible or make the piping diameter larger.
· When installing a flow meter to the air circuit, refer to “5-4. Flow - Pressure characteristics” to choose the
product type so that the flow of the bar does not exceed the flow meter rated flow range. If the bar's flow
consumption is larger than the rated flow of the selected flow meter, the flow supplied to the bar is limited,
thus deteriorating neutralization performance.
3-1-3. Selection of piping port size
·
When air is supplied, choose the ionizer piping fitting referring to the table7 [Recommended piping port size].
·
Connect piping for air supply through the One-touch fitting(s) either to one end or both ends depending on
the bar length.
·
If a tube is used which is thicker than the recommended tube, neutralization performance will be deteriorated
due to a shortage of air flow.
