3 Installation
3.1 Installation
Warning
• Do not install the product unless the safety instructions have been
read and understood.
• When mounting the product, tighten with the recommended
tightening torque of the following screws.
- Top surface and side surface mounting: 0.56 to 0.76 N•m
- Bottom mounting: 0.29 to 0.30 N•m
• When installing the product, secure the space required for
maintenance and inspection of the product
• Do not drop, hit, or apply excessive impact to the product.
3.2 Environment
Warning
• Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
• Do not use in an explosive atmosphere.
• Do not expose to direct sunlight. Use a suitable protective cover.
• Do not install in a location subject to vibration or impact in excess of
the product's specifications.
• Do not mount in a location exposed to radiant heat that would result
in temperatures in excess of the product's specifications
• This product does not have a built-in suction filter. If there is dust in
the usage environment of the product, consider using a vacuum filter
(AFJ series)
• Do not use in place where static electricity build up can occur.
• Do not use in an environment where surges occur.
3 Installation - continued
3.3 Air Supply
Caution
● Do not use air containing chemicals, synthetic oils containing organic
solvents, salts, or corrosive gases.
● Recommended quality of the supplied air be equivalent to the
compressed air cleanliness grade "2: 6: 3" according to ISO8573-1:
2010.
• Do not supply the pressure in excess of the product's specifications.
3.4 Piping
Caution
• Before connecting piping make sure to clean up chips, cutting oil,
dust etc
• When installing piping and fittings, make sure that no sealing material
gets inside the port. When using sealing tape, wind it with one thread
left.
• Tighten fittings to the specified tightening torque shown in the table
below.
Port type Port size Recommended tightening

Manual of supply valve
Manual of release valve
Refer to the operation manual of the solenoid valve JSY3000 series
for the manual operation method.
4.2 Release flow adjusting needle
When the release valve is turned on, vacuum break air is let out.
The release flow adjusting needle allows to control the vacuum break
air flow rate.
To adjust the break air flow, pull the push-locking handle to unlock it.
Then, turn the push-locking handle clockwise to reduce the vacuum
break flow, and turn the handle anti-clockwise to increase the flow.

7 Maintenance
7.1 General Maintenance
Caution
• Not following proper maintenance procedures could cause the
product to malfunction and lead to equipment damage.
• If handled improperly, compressed air can be dangerous.
• Maintenance of pneumatic systems should be performed only by
qualified personnel.
• Before performing maintenance, turn off the power supply and be
sure to cut off the supply pressure. Confirm that the air is released to
atmosphere.
• After installation and maintenance, apply operating pressure and
power to the equipment and perform appropriate functional and
leakage tests to make sure the equipment is installed correctly.
• If any electrical connections are disturbed during maintenance,
ensure they are reconnected correctly, and safety checks are carried
out as required to ensure continued compliance with applicable
national regulations.
• Do not make any modification to the product.
• Do not disassemble the product, unless required by installation or
maintenance instructions
• Implement the maintenance and check shown below to use the
multistage ejector safely and in an appropriate way for a long period
of time.
• Drain the air filter and mist separator regularly
• Replace the sound absorbing material (silencer) built into the ejector
regularly
• Refer to the online operation manual for replacement parts.
• Do not use benzene or thinner for cleaning.
7.2 Replacement method of sound absorbing material (ZL3)
1) Loosen the two mounting screws of the silencer assembly and
remove the silencer case (Fig.1)
2) Replace the sound absorbing material inside the silencer case (Fig.2)
3) Attach the silencer assembly using the mounting screws.
(Recommended tightening torque: 0.76 to 0.84 Nm)
