may result.

● If this product is used in an airtight room, ozone emitted from this pro

duct may

be detrimental.

Therefore, in order for this product to be used in an airtight room,

be sure to keep the room ventilated.

● Do not direct ionized air toward the face. Ozone may cause irritation to places
such as the nose and throat.

● Do not look directly into the white LED spotlight. It may cause injury to the eyes.

● Since the tip of the discharge needle is sharp, take sufcient care in handling the
discharge needle, or injuries may result.

● When air is not being supplied to this product, turn off the power in order

to stop

discharging

from occurring. If discharging is allowed to continue while

air is not
being supplied, the ozone concentration will rise and accidents or operating
problems may occur.

● This product includes precision components, so do not drop it or hit it against
other objects. If this is not observed, accidents or problems with operation

may

● 1 and 5 are connected to the AC adapter.

● Use the accessory connector wiring terminal to connect external input or GND.

● When using external input

When using external input, ionized air discharging can be carried out using the
same ON/OFF operations as trigger input.

Note: The COM (-) terminal which uses external input is connected internally to 0V, the GND terminal and the nozzle

metallic parts. If external input ON/OFF switching is carried out using an external control device instead of an in­dependent mechanical-type switch, or if the 0V potential of the external control device and the grounding poten­tial of the place of use are different (such as in the case of positive power supply grounding), the external control
device used for external input should have an insulated on/off procedure for the 0V line (such as photocoupler
output or relay output) in order to prevent short-circuits from occurring.

4 WIRING / PIPING

● Use the accessory relay cable to connect the main unit and the AC adapter.

● Use the accessory straight joint to connect a suitable air tube to the main unit.

● Connect the GND terminal of this product to a secure ground when using it.

● Since the pressure will drop when the air piping

from the main pressure supply is

extended

or pneumatie-components (e.g., needle valve, speed-controler, minil-

ter) are added, keep an eye on the pressure supply to

the ionizer maiking sure it

isn’t in short supply

. For the pneumatic-components, select those that can accom-

modate the air supply ow rate.

* The air supplied should be dry, clean air (air drier: dew point approx. -20°C, air l-

ter: mesh size of approx. 0.01μm).

CAUTION

● Turn off the power and air and make sure that the supply of air has been fully
shut off before carrying out any wire and tube connection work. If this is not
done, accidents or problems with operation may occur.

● The metal parts of the nozzle are connected inside the product to the 0V and
GND terminal. Do not connect it to objects with a different electrical potential
such as the conductive parts of external devices. If the supplied air contains

any

particles

other than air or any corrosive gases, accidents or problems with opera-

tion may occur. In addition, if air which contains impurities

such as carbon dust

or air which

contains moisture or oil is used, accidents or problems with opera-

tion may also occur.

● Do not modify the nozzle or install the nozzle to any other appliances, otherwise
correct charge removal performance may not be obtained, and accidents or
problems with operation may occur

.

5 OPERATION

1. Use the mode select switches to select the required settings.

2. Face the ionizer toward the electrostatically-charged object and pull the trigger.

When the trigger is pulled, dust removal operation will start, and when

the trigger

is released, dust removal operation will stop.

6 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 re­moval 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, afx 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.
