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.

piping to the exhaust (3 / E) port.
3.5 Wiring to the solenoid valve and pressure switches
Refer to the operation manual of solenoid valve (JSY3000 series) and
pressure switch (ZSE10 series).
4 Settings
4.1 Manual Override (With supply valve and 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 electricalconnections 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)
7.3 Silencer assembly (ZL6)
1) Align the hook of the silencer assembly with the groove of the body,
break it, and push it in the direction of the arrow until it clicks.
2) When removing, slide the silencer assembly in the direction opposite
to the mounting direction to remove it.

8 Limitations of Use
8.1 Limited warranty and Disclaimer/Compliance Requirements
Refer to Handling Precautions for SMC Products.
Caution
●Exhaust from Multistage ejector
1) For the silencer exhaust type, make sure that there is no obstruction
around the exhaust port.
2) In the case of port exhaust type, exhaust resistance may be affected
depending on the pipe diameter and length, so make sure that the
back pressure is 1 kPa or less.
3) Do not block the exhaust port.
●Ejector exhaust noise
When the vacuum ejector generates a vacuum, an intermittent noise
(abnormal noise) may be generated from the exhaust section near the
standard supply pressure where the vacuum pressure peaks, and the
vacuum pressure may not be constant. There is no problem in use as
long as the vacuum pressure range is sufficient for adsorption, but if you
are concerned about the sound or affect the setting of the pressure
switch, slightly change thesupply pressure and reduce the range of the
intermittent sound. Please avoid it.
●About the breaking flow rate adjusting needle
1) Leakage cannot be reduced to zero when the needle is fully closed.
2) Check that the push lock handle is locked.
3) When unlocking the push lock handle, do not pull it with excessive
force.
4) This release flow adjustment needle does not rotate more than 12
rotations from fully closed. If you try to rotate the needle any further,
it may be damaged.
5) Do not tighten the handle with tools such as pliers.
●About solenoid valve and pressure switch
For the solenoid valve (JSY3000 series) and pressure switch (ZSE10
series), refer to each instruction manual.
