CARE AND MAINTENANCE
●
Be sure to turn off the power and air before carrying out cleaning and maintenance.
●
Make sure that the supply of air has been fully shut off and that all pressures at
the product and inside the tubes are at zero before continuing. If this is not done,
air pressure may cause operating problems or accidents.
●
The discharge needle has a sharp point, so be very careful when cleaning the needle.
●
Clean the discharge needle regularly about once a week, otherwise optimum charge re-
moval performance may not be obtained and accidents or operating problems may occur.
●
The discharge needle is a consumable part. If charge removal performance does not return
to normal after the discharge needle has been cleaned, then the needle should be replaced.
Cleaning and replacing the discharge needle
1.
Turn off the power and check that the air pressure inside the air tube has dropped to zero.
2.
Remove the nozzle guard, turn the nozzle counterclockwise and remove it.
3.
Remove the insulating pipe and the attachment.
4.
When carrying out cleaning, use a cotton swab moistened in alcohol or similar to remove any
dirt from the needle and the area around it. (If replacing the discharge needle, use needle nose
pliers or a similar tool to pull out the needle, and then insert a new needle as far as it will go.)
5.
After cleaning or replacing the needle, return the attachment, insulating pipe and
nozzle to their normal installation positions. Turn the nozzle clockwise to install it.
The tightening torque for the nozzle at this time should be 3N•m or less.
Lastly, affix the nozzle guard.
*: Do not touch the tip of the discharge needle against tools or any other hard surfaces. If
the discharge needle is damaged, optimum charge removal performance may not be
obtained and accidents or problems with operation may occur. In addition, do not touch
the stopper ring area, otherwise the stopper ring may slip out of position, and it may
not be possible to reinstall it. When handling the discharge needle with tools, hold the
discharge needle at the middle and avoid applying excessive force to the needle.
Note: When installing the attachment, make sure that it is facing the correct direction. If it is installed so that it is facing
the wrong direction, it will not be possible to fully tighten the nozzle.

The solenoid valve is a consumable part (open/close operations: ap-
prox. 8,000,000). If it no longer opens and closes normally, stop using
the ionizer and replace the solenoid valve.
Solenoid valve replacement procedure
1.
Check that the power is turned off and that the air pressure inside the air tube has
dropped to zero.
2.
Remove the back cover. Remove the four M3 mounting screws. (A in diagram below)
3.
Disconnect the air tube from the solenoid valve. (B in diagram below)
4.
Disconnect the solenoid valve lead wire connector.
5.
Remove the two M3 mounting screws. (C in diagram below)
6.
Disconnect the air pipe from the solenoid valve. (D in diagram below)
7.
Install the new solenoid valve, and then install the M3×45 mounting screws and
connect the air tubes and the solenoid valve lead wire connector. Tighten the
M3×45 mounting screws at a torque of 0.2N•m or less.
8.
Install the back cover. Let the lead wire pass the lead wire holder, and make sure that the cov-
er will not catch lead wire. Tighten the M3×10 mounting screws at a torque of 0.4N•m or less.

TROUBLESHOOTING
When an error is detected, the white LED flashes. (It also flashes even when the
LED illumination mode is set to “Always OFF”.) If the white LED is flashing, carry out
the following checking operations. When checking the discharge area, always be
sure to turn off the power before carrying out the checking.
●
Turn off the power and check that the tip of the needle is intact and that there is
no dirt on it, and that the needle is installed correctly.
●
Check that there are no foreign objects inside the nozzle.
●
Check that the nozzle is installed correctly. (Including the attachment and the insulating pipe)
● Check that the air pressure is within the specification range.

CAUTIONS
●
This product has been developed / produced for industrial use only.
●
Do not use this product for any purpose other than charge removal and dust removal.
● Do not use this product in enviroments which are outside the specification range,
otherwise operating problems or damage may occur. In addition, the operating life
of the product may become significantly reduced.
●
Never disassemble, repair or modify this product, otherwise operating problems or
accidents may occur.
●
Do not dispose of this product by burning it, otherwise it may explode or toxic
fumes may be generated.
●
This product generates ozone, so be sure to provide adequate ventilation if using
it in a confined space.
●
Do not run the wires together with high-voltage lines or power lines or put them in
the same raceway. This can cause malfunction due to induction.
●
Be sure to turn off the air and the power supply before carrying out any cable con-
nection or inspection work. If this is not done, operating problems, damage or
electric shocks may occur.
●
After connecting the cables, check that the air piping and power supply connec-
tions are correct before turning on the power. If the wires or cables are connected
incorrectly, operating problems or accidents may occur.
●
Verify that the supply voltage variation is within the rating.
●
Do not turn the power back on immediately after it has been turned off, otherwise
operating problems or accidents may occur. In addition, the operating life of the
product may become significantly reduced. Wait at least 2 seconds before turning
the power back on again.
● Do not use the power plug of the AC adapter if it has become dusty, otherwise fire
may occur.
●
The air tube or cable may be broken if excessive tension or other stress is applied
to the air tube and cable. Consider appropriate margins of the air tube and cable
within the work area when using them.
●
Do not use any cables which have any damage (such as splitting or cracking),
otherwise operating problems or accidents may occur.
●
Avoid using the product in places where there are high levels of steam or dust in
the air or where it might be directly exposed to water, oil or welding spatter.
●
Do not touch the discharge needle with hard objects such as tools. If the dis-
charge needle becomes broken, it will not provide sufficient charge removal per
-
formance, and moreover operating problems or accidents may occur.
●
If this product ceases functioning or is no longer required, dispose of it according
to appropriate local waste disposal regulations.
●
This product is a high-precision device, and should be handled with care.
