range of specifications, as this can cause damage or
malfunction. (Refer to the specifications shown in the catalog.)
Please contact SMC if using for fluids other than compressed
air. We do not guarantee against any damage if the product is
used outside of the specification range.
2. Ventilation
Provide ventilation when using a valve in a confined area, such
as in a closed control panel. For example, install a ventilation
opening, etc. in order to prevent pressure from increasing inside
of the confined area and to release the heat generated by the
valve.
3. Disassembly and modification is prohibited.
Do not disassemble the product or make any modifications,
including additional machining.
This may cause human injury and/or an accident.
4. Air quality
Use clean air.
Do not use compressed air that contains chemicals, synthetic
oils, including organic solvents, salt or corrosive gases, etc., as
it may cause damage or malfunction.
For detailed information regarding the quality of the
compressed air described above, refer to SMC's "Air Cleaning
Systems".
5. Ambient environment
Use within the operable ambient temperature range. After
confirming the compatibility of the product's component
materials with the ambient environment, operate such that
fluid does not adhere to the product's exterior surfaces.
6. Countermeasures against static electricity
Take measures to prevent static electricity since some fluids
can cause static electricity.
1. Leakage voltage
When a resistor and a switching element are used in parallel or
C-R device (surge voltage suppressor) is used for the protection
of the switching device, note that leakage voltage will increase
because earth leakage current passes through the resistor and
C-R device. The suppressor residual leakage voltage should be
0.2 VDC or less.
2. Low temperature operation
When using the valve in a low temperature condition, take
appropriate measures to avoid freezing of the drainage,
moisture, etc. at low temperatures. Unless specified, the valve
can be used down to -10oC.
3. Mounting orientation
Mounting orientation is not specified.

1. Operation Manual (this copy)
Install and operate only after reading the operation manual
carefully and understanding the contents.
Keep the manual handy, so that it can be referred to as
necessary.
2. Maintenance space
When installing the products, allow access for maintenance.
3. Observe the tightening torque for screws.
Tighten the screws to the recommended torque, when mounting
the product.
4. If air leakage increases or equipment does not
operate properly, STOP operation.
After installation and maintenance, apply air and power supplies
to the equipment and perform appropriate functional and
leakage inspections to make sure the equipment is mounted
properly.
5. Painting and coating
Warnings or specifications printed or labeled on the product
should not be erased, removed or covered.

Lubrication
1. Lubrication
Do not supply oil.
Air Supply
1. Type of fluids
Please consult with SMC when using the product in applications
other than compressed air.
2. Large amount of condensate
Compressed air containing a large amount of condensate can
cause malfunction of pneumatic equipment. An air dryer or
water droplet separator should be installed upstream from
filters.
3. Draining control
If condensate in the drain bowl is not emptied on a regular basis,
the condensate will overflow and enter the compressed air lines.
This will cause a malfunction of pneumatic equipment. If the
drain bowl is difficult to check or remove, installation of a drain
bowl with an auto drain option is recommended.
4. Use clean air.
Do not use compressed air that contains chemicals, synthetic
oils, including organic solvents, salt or corrosive gases, etc., as
it can cause damage or malfunction.
For detailed information regarding the quality of the compressed
air described above, refer to SMC's "Air Cleaning Systems".
1. If ultra dry air is used as a fluid, the lubrication
characteristics of the equipment will deteriorate and
this can affect the reliability (life) of the product.
Contact SMC beforehand, if using ultra dry air.
2. Install air filters.
Install air filters close to valves on the upstream side.
It is strongly recommended to use a filter with a filtration rating
of 0.01 μm or less. Be careful to prevent the supply pressure to
the valve from decreasing.
3. Take appropriate measures to ensure air quality,
such as by providing an after cooler, air dryer, or
water separator.
Compressed air that contains excessive drainage may cause
malfunction of valves and other pneumatic equipment.
Therefore, take appropriate measures to ensure air quality,
such as by providing an after cooler or water separator.
4. If excessive carbon powder is seen, install a mist
separator on the upstream side of the valve.
When the amount of carbon particles generated from the
compressor is excessive, they will stick inside of the valve, and
may cause malfunction or internal leakage.Refer to SMC’s Best
Pneumatics catalog for further details on compressed air
quality.
Operating environment
1. Do not use in an environment where corrosive gases,
chemicals, sea water, water or steam are present.
2. Do not use in an atmosphere containing flammable
or explosive gases. Fire or an explosion can result.
The product is not designed to be explosion proof.
3. Do not operate in a location subject to vibration or
impact.
4. The valve should not be exposed to prolonged
sunlight. Use a protective cover, if necessary.
5. Shield the product from radiated heat generated by
nearby heat sources.
6. Employ suitable protective measures in locations
where there is contact with oil and welding spatters,
etc.
7. When the solenoid valve is mounted onto a control
panel and energizing time is long, take measures
against radiation in order to keep the valve
temperature within the specified range.
Maintenance
1. Maintenance should be performed according to the
procedure indicated in the Operation Manual (this
copy).
Improper handling may cause an injury, damage and/or
malfunction of equipment and machinery.
2. Low frequency operation
Operate valves at least once every 30 days to prevent
malfunction. (Refer to the precautions for "Air Supply" and
follow the instructions)
3. Removal of product
