INSTALLATION
1 Installation of ground/earth-leakage breaker
WARNING
To prevent accidents by electric shocks if electric leakage should occur,
Install an earth-leakage breaker on the power source to which this dust collector is to be connected.
Make sure before use that this dust collector is grounded. It is recommended that grounding is
performed for safety even in case of a dust collector with the power source for which a current-
operating-type earth-leakage breaker is installed. The earth-leakage breaker features less than 15
milliampere (mA) rated sensitivity current and less than 0.1 second operating time.
Perform settings according to following procedures:
Fasten with screws the grounding terminal of a groundinggreen wire tip of the power supply cord, and connect it tothe grounding wire as illustrated in the right figure.
Be sure that no tension is applied to the grounding greenwire.
Specialized work is required for the installation of an earth-leakage breaker as well as groundingaccording to the technical standards on electric installation and indoor wiring regulations. (Anelectrician with a diploma is required for the grounding installation, and therefore consult withyour electrical work shop. Fee-charging.)
For grounding work
s Specify the third class grounding work.s If there is a grounding terminal already installed, check if grounding capacity is sufficient.
For earth-leakage breaker work
s Install an earth-leakage breaker with a capacity that is above the rated current.(Rated current of the dust collector is indicated in the name plate.)
s If there is an earth-leakage breaker already installed, check out the above-mentioned capacity.

2 Extension of power supply cord
WARNING
When extending the power supply cord, be sure to replace the whole cord with a completely new
one. Because, addition of a new cord to the existing cord can result in a risk for a fire and electric
shock.
INSTALLATIONNOTE Proper work with a minimum loss is essential for the piping of hoses and hoods, considering the
surrounding conditions, working environment, etc. Procure separately sold component parts and
ask your dealer for installation.
When using metal piping parts, be sure to perform complete insulation between a wall surface and
the metal piping parts inside the wall surface.
Some dust particles may blow out of the discharge port immediately after installation or elimination
of dust particles. Installation of an exhaust duct is recommended depending on the working
environment.
5 Connection of compressed air
Compressed air connecting holes are provided on two sides.
Use the compressed air connecting holes as desired in the following manners according to working
conditions.
s When connecting compressed air, perform connection in order of 1 1/4 nipple, 2 air filter and 3 airtube.
s Check and confirm that a 1/4 plug is firmly secured to a joint on the side to which the air tube is notconnected.
NOTE Before operation of this dust collector, make sure that the above-mentioned connection is
completely carried out and that a panel cover, filter cover, and dust cover are all fixed with clamps.
Be sure to use specified pressure (4 - 7 [kg/cm2]) for compressed air.
Use of pressure other than what is specified can result in the damage of an air tank and the failure
of an electromagnetic valve. (When the 1/4 plug and 1/4 nipple are once removed, prevent air
leakage with sealing tapes, etc.)

BEFORE USE
1 Check the following points at first
Check and confirm that the dust box is empty. If dust particles are accumulated, get rid of them by
cleaning before use.
Make sure that there is no air leakage in the packing, suction hose and other piping parts and that they
are all set properly.
Make sure that the panel cover, filter cover and dust cover are completely secured with clamps.
2 Connection of power supply cord
Connect the power supply cord correctly to the power source specified in the name plate. In this case,
connect a grounded phase (S phase) among three power supply wires to the white wire of the power
supply cord.
3 Check direction of motor rotation
Turn ON the operation switch on the operation panel and check that a [FAN REVERSE] lamp of
the alarm display does not light up. In case of a reverse rotation, a lamp lights up and the motor does
not rotate.
In this case, turn OFF the main power switch of the original installation and switch over the connection
of R phase and T phase of the power supply cord.
To re-start operation, press the alarm reset switch and then press the operation switch.

Switch connection
Wait for more than a minute after eliminating dust particles in the filter, remove one piece of clamp,
draw out the dust box, and then discard accumulated dust particles.
Try to discard the dust particles at the earliest opportunity, and the dust articles spilled out of the dust
box should also be scraped out of the main unit.
WARNING
AFTER USE
1 Elimination of dust particles from filter
Manual pulses after the stop of operation can eliminate dust particles more effectively. Remember
that a pulse noise is made four times during pulse application. During manual pulse application after
the stop of operation, dust particles flow backward and therefore do not look into the suction port, etc.
NOTE Before taking actions listed in the following items, make sure that the operation switch is turned OFF,
the main power switch is turned OFF and suction is completely stopped.
2 Cleaning of dust box
WARNING
Discard dust particles accumulated in the dust box every day. Otherwise, there is not only a re-
adhesion of blown-up dust particles to the filter in subsequent operation but also a cloud of dust
articles is produced, causing a risk for explosion of dust particles.
3 Cleaning and inspection of filter
Never open the panel cover, filter cover and dust cover while a mark is displayed on the digital
display of the operation panel. Do not look into the suction port for dust particles as there is a risk
of the dust particles to scatter.
Dust eliminating operation by pulse alone is not enough when the filter is heavily clogged up. Under
such circumstances, suction power naturally downs. Clean up the filter on a periodic basis (more than
once in every 1 - 2 months).
s Extracting filter
(1) Remove two clamps andopen the filter cover.
(2) Remove the wing bolt and then quietly extractthe filter along with the filter holder.

s Installing filter
1 To begin with, insert the filters into thefilter holder. Insert two filters into onefilter holder. Be sure to insert the filtervertically.
2 Mount the filters on the left and right filter guiding plates and thrust them in until they contact the filter stop.
3 Then, lift the front of the filter holder up and fasten it scurely with the wing bolt until it hits the filter supportplate. If a male screw and a female screw of the wing bolt do not engage well each other when fastening thefilter holder, the filter holder is not pushed in sufficiently. Be sure to push it in completly.
WARNING
Install the filter properly before use.
Do not use the dust collector with the filter removed or at an erroneously installed position. Avoid
the use of a torn filter, too. Otherwise, dust particles can enter into the motor and can result in
the machine failure and damage of motor by a fire.

NOTE It is recommended that some spare filters be stocked since the filters are expendable.
Try to maintain the performance of the filter and restore its suction capacity by brushing
and washing the filter with water and eliminating clogged dust particles as illustrated
below. After washing the filter with water, dry it completely in the shade before use.
Depending on the kind of dust particles, think about how to treat waste fluid while
washing the filter with water.
Filter* Scrape out dust particles
using a brush and othereffective tools.
* Wash off dust particles underrunning water.
