Chapter 1 Product Usage Precautions
1.1 Safety Notations
This instruction manual describes usage precautions with the below listed symbols.
Be sure to read the instructions.
Symbol
Meaning
WARNING
Indicates a hazardous situation which, if not avoided, could result in personal death or
serious injury.
CAUTION
Indicates a hazardous situation which, if not avoided, could result personal injury or
damage to the device.
Indicates a prohibited action (which MUST NOT be done).
Indicates a mandatory action (which MUST be done).
1.2 Precautions for Transport, Storage, and Relocation
WARNING
•Transportation must be done using at least two people.
Injury may result due to fall hazard.
CAUTION
•Relocation and storage must be done in a safe location within the
temperature range of -10°C to 60°C at relative humidity of 80% or less.
1.3 Precautions for Installation
WARNING
•Do not install the device in or around an area with flammable, explosive, or
corrosive mist, smoke, or gases.
CAUTION
•This device is designed for installation in a cleanroom or a clean factory.
Avoid installation in other areas, such as outdoors.
•Ensure a wide suction port.
If the device is used continuously with a narrow suction port (i.e., at high
pressure), the motor may become hot as it cannot be cooled.
•Install the device in a horizontal, vibration-free location as it contains rotating
equipment.
•Install the device at normal temperature (ambient temperature 0°C to 40°C, at
humidity 80% or less) without dew condensation.
High temperature or dew condensation may cause failure of electrical
components or electric shock.
•Beware that suction ambient temperature (temperature around the dust to
be collected) is low enough, because otherwise the motor may lead to
performance reduction or failure.
•The installation site should be at an altitude of 1,000 m or less.

Chapter 1 Product Usage Precautions

1.4 Precautions for Operation
WARNING
•Do not suck the following substances:
Flammable substances ...Gasoline, thinner, benzine, kerosene, paints, etc.
Explosive dusts ...........Aluminum, magnesium, titanium, zinc, epoxy, etc.
Sparky dust .................Dust containing sparks from high-speed cutting
machine, grinder, welding machine, etc.
Fire source ..................Cigarette, and liquid such as oil and chemical
Others..........................Liquid such as water, oil, chemical
•Do not use the device in or around an area with flammable, explosive, or
corrosive mist, smoke, or gases.
•Ensure secure connections, without bending or pulling cables with excessive
force.
Fire or electric shock may result.
•Ensure that the power supply conforms to the specifications of the device.
•Use the device to suck dry dust without potential dust explosion.
•Be sure to connect the ground wire.
CAUTION
•Do not move the device while in operation.
•Use the device in locations of pollution degree 2.
•Use a power supply of overvoltage category II.
•Turn off the main power switch in case of power outage.
Injury or device damage can occur when power returns.
•Ensure that filters are installed correctly.
If filters are missing, clogged, or broken, foreign matter may enter the motor,
causing failure.
1.5 Other Precautions
WARNING
•Do not disassemble or alter the device.
Failure to observe can cause electric shock or injury.
For internal checkup or repair, contact your dealer.
•Follow the information in the instruction manual when performing installation,
connection, starting, operation, checkup, and fault diagnosis.
Working in a wrong manner may lead to fire, electric shock, or injury.
CAUTION
•When discarding the device, dispose of it appropriately as an industrial
waste.

3.1.2 Wiring and Piping
■Wiring
WARNING
•Perform wiring firmly, without bending or pulling cables with excessive force.
Fire or electric shock may result.
•Ensure that the power supply conforms to the specifications of the device.
•Be sure to connect the ground wire.
CAUTION
•Avoid multiple connections as they can cause voltage reduction.
At reduced voltage, the device may fail to operate normally, resulting in
failure.
The device is powered by a single-phase supply.
The tolerance of the supply voltage is 10%.
1. Connect the device attachment plug of the power cord to the power connector on the device.
2. Connect the power supply end of the power cord to the power outlet.
■Piping
1. Turn the removable flange clockwise until it is
secured on the suction port.
2. Connect the suction tube (to be prepared
separately) to the removable flange.
IMPORTANT
•Ensure appropriate piping during operation.
The piping should be as short as practicable, with the piping port diameter not too
small.
3.2 Operation
1. Turn on the main power switch.
The display indicates the program version
and the ID for RS485 communication.
2. Press the ON button on the AT3 panel.
The device starts operation.
3. Check that abnormal noise is not generated
and the suction is appropriate.
4. Set a desired suction power level by
pressing the Left/Right arrow buttons.
The suction power is indicated by the
suction power level lamps (1 to 7).
IMPORTANT
•Leave an interval of three minutes or more between on/off switching.Repeated
on/off switching at intervals of less than three minutes, in particular less than 30
seconds, may cause failure.

3.3 Registering Initial Pressures
Air volume reduction due to filter clogging is judged based on a registered initial differential pressure and
indicated as low air volume (WARN4). Register initial pressures through these steps:
1. Perform the wiring and piping of the device.
2. Start the device at a desired suction power level.
3. Press and hold down the ENTER button for three seconds.
The display shows “Initial DP Get Y”, prompting confirmation to register/update initial pressures.
4. To proceed with registration/update, press the ENTER button.
The device starts to acquire initial pressure.
If you do not want update, press the MODE SELECT button to return to normal operation.
5. The device runs through a sequence of suction power levels 1 to 7, to automatically acquire the
differential pressure for each level.
While the device is acquiring initial pressures, the display alternates between the “Initial DP Check”
message and the “suction power level and differential pressure” values.
6. When the registration completes, the display shows the “Initial DP Entry” message and the device
returns to normal operation.
IMPORTANT
•Ensure that the filters are new.
•Update registered initial pressures once again if piping is changed or all filters are
replaced (except for the exhaust filter) after registration of initial pressures.
•If initial pressures are not registered, an “initial pressure unregistered” warning
(WARN6) appears.
•The registered initial pressures can be cleared by holding down the OFF button for
three seconds when the device is in stop state.
●Clearing registered initial pressures
1. Hold down the OFF button for three seconds when the device is in stop state.
The display shows “Initial DP Clr Y”, prompting confirmation to clear registered initial pressures.
2. To clear them, press the ENTER button.
If you do not want to clear them, press the MODE SELECT button to return to normal operation.
3. When the clearing completes, the display shows the “Initial DP Clr” message and the device
returns to the stop state.
