Caution
1. Connect the piping after checking the arrow indica-
tion showing the flow direction on the body. If the
piping is connected the other way around, it is not
possible to seal the element.
2. Positive and negative pressures cannot be used to-
gether in the same circuit.
3. Allow a sufficient margin of tube length when pip-
ing, in order to prevent twisting, tensile, moment
loads, vibration or impact being applied to the
tubes and filter body.
Mounting
Warning Warning
Caution
1. Element should be replaced in either of the two
cases below.
1) When pressure drop reaches 0.1 MPa in a positive pressure
or 20 kPa in a vacuum pressure.
2) When the set values (flow rate, vacuum reaching time)
change.
2. During disassembly and assembly, confirm that
there are no scratches or damage, etc, on the O-ring.
3. Before using, confirm there is no leakage after re-
placing elements.

Warning
6. When the element becomes clogged, stop operation
and adjust the internal pressure of the filter to at-
mospheric pressure before replacing the element.
1. Operation manual
Install the products and operate them only after reading the op-
eration manual carefully and understanding its contents. Also,
keep the manual where it can be referred to as necessary.
2. Maintenance space
Allow sufficient space for maintenance and inspection.
3. Observe the tightening torque for screws.
Tighten the screws to the recommended torque for mounting
the product.
4. Connect tubing to the IN and OUT One-touch fit-
tings in accordance with the precautions for One-
touch fittings.
1. Perform maintenance inspection according to the
procedures indicated in the operation manual.
If handled improperly, malfunction and damage of machinery
or equipment may occur.
2. Maintenance work
If handled improperly, compressed air can be dangerous.
Assembly, handling, repair and element replacement of pneu-
matic systems should be performed by a knowledgeable and
experienced person.
3. Drain flushing
Remove drainage regularly from the air filters, etc.
4. Removal of equipment, and supply/exhaust of com-
pressed air
When components are removed, first confirm that measures
are in place to prevent workpieces from dropping, run-away
equipment, etc. Then, cut off the supply pressure and electric
power, and exhaust all compressed air from the system using
the residual pressure release function.
When machinery is restarted after remounting or replacement,
confirm that the equipment is operating normally.
5. The performance of an ejector will deteriorate due
to clogged suction filters and silencers.
High flow filters should be used, especially in dusty locations.
If a filter is required on the release pressure side, a different
filter should be prepared.
∗ Not possible to use vacuum pressure and positive pressure
together in the same line.
