3 Installation
3.1 Installation Warning
•Do not install the product unless the safety instructions have been read
and understood.
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.
3 Installation - continued
•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.
•Do not use in high humidity environment where condensation can
occur.
3.3 Piping Caution
•Before connecting piping make sure to clean up chips, cutting oil, dust
etc.
•When installing piping or fittings, ensure sealant material does not
enter inside the port. When using seal tape, leave 1.5 to 2 threads
exposed on the end of the pipe/fitting.
•Tighten fittings to the specified tightening torque.
3.4 Lubrication Caution
•SMC products have been lubricated for life at manufacture, and do not
require lubrication in service.
•If a lubricant is used in the system, refer to catalogue for details.
3.5 Air supply Warning
•Use clean air. If the compressed air supply includes chemicals,
synthetic materials (including organic solvents), salinity, corrosive gas
etc., it can lead to damage or malfunction.
Caution
•Install an air filter upstream of the valve. Select an air filter with a
filtration size of 5 μm or smaller.
3.6 Mounting Warning
•Do not perform mechanical operation exceeding the operation limit
position. The mechanical valve itself may be damaged leading to
equipment malfunction.
•Never perform additional machining such as enlarging the body
mounting holes as it could lead to unexpected abnormal conditions
such as air leakage.
3.6.1 Stroke range Warning

3.7 Operation Warning
•Operate the manual operation type mechanical valves (such as push
button, and toggle lever types) with your finger.
•The use of equipment such as a cylinder, cam or hammer, can result
in the actuator and the valve being damaged.
•Do not operate over the operation limit. If excessive operation force is
applied over total travel position, actuator part can get deformed and
lead to equipment malfunction.
•When operating the mechanical operation type mechanical valves,
select the angle and the maximum speed limit of cam and dog so that
valves do not operate over the following maximum values.

Caution
If the operating condition is maintained for long periods of time, it may
take some time for the valve to restart due to the adherence of the seals
and there might be a delay for recovery.
4 How to Order
Refer to catalogue for ‘How to Order’.
5 Outline Dimensions
Refer to catalogue for outline dimensions.
Caution
Dimensions of the roller lever type may exceed the values specified in
the catalogue if the roller lever is positioned in any direction other than
upwards, due to the design of the lever.
6 Maintenance
6.1 General maintenance Warning
•To prevent unexpected movements of the pneumatic actuator,the user
shall consider the state of the valve before conducting maintenance.
Additional consideration shall be given when the valve is held in the
ON position by an external mechanism such as cam, lever, etc., or in
the case that locking type valve actuators are used.
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.

6 Maintenance - continued
•Do not make any modification to the product.
•Do not disassemble the product, unless required by installation or
maintenance instructions.

button.
7 Limitations of Use
Warning
The system designer should determine the effect of the possible failure
modes of the product on the system.
7.1 Limited warranty and disclaimer/compliance requirements
Refer to Handling Precautions for SMC Products.
7.2 Effect of energy loss on valve switching
Valves with locking type actuators or valves operated by an external
mechanism such as cam, lever, etc., remain in the ON position even
when the energy source is interrupted. If the air supply is reconnected
again, e.g. after maintenance, it may behave unexpectedly.
7.3 Holding of pressure
Since valves are subject to air leakage, they cannot be used for
applications such as holding pressure (including vacuum) in a system.
7.4 Safety related applications
This product shall not be used as an emergency shut-off valve or as any
part of an emergency stop circuit.
Caution
7.5 Low temperature operation
Unless otherwise indicated in the specifications for each valve, operation
is possible to -5 ˚C, but appropriate measures should be taken to avoid
solidification or freezing of drainage and moisture, etc.
8 Product Disposal
This product shall not be disposed of as municipal waste. Check your
local regulations and guidelines to dispose this product correctly, in order
to reduce the impact on human health and the environment.
