Specifications

1. Confirm the specifications.
The products appearing in this catalog are designed for use only
in compressed air systems (including vacuum).
Do not use outside the specified ranges of pressure, temperature,
etc., as this may cause damage or faulty operation. (Refer to
specifications.)
Consult with SMC if fluids other than compressed air (including
vacuum) are to be used.

Vacuum Equipment Precautions 1
Be sure to read before handling.
1. Read the instruction manual carefully.
The product should be mounted and operated with a good under-
standing of its contents. Also, keep the manual where it can be
easily referred to at any time.
2. Ensure space for maintenance.
Ensure the necessary space for maintenance activities.
3. Be sure to tighten screws with the proper
torque.
When mounting, tighten screws with the recommended torque.
1. Preparation before piping
Before piping is connected, it should be thoroughly blown out with
air (flushing) or washed to remove chips, cutting oil and other
debris from inside the pipe.
2. Wrapping of pipe tape
When screwing together pipes and fittings, etc., be certain that
chips from the pipe threads and sealing material do not get inside
the piping.
Further, when pipe tape is used, leave 1.5 to 2 thread ridges
exposed at the end of the threads.
1. Types of fluid
This product is designed for use with pressurized air. Consult with
SMC if a different fluid is to be used.
Consult SMC regarding products to be used with general purpose
fluids, to confirm which fluids may be used.
2. When there is a large amount of drainage
Pressurized air containing a large amount of drainage can cause
the malfunction of pneumatic equipment. An air dryer or Drain
Catch should be installed upstream from filters.
3. Drain management
If the air filter drains are not flushed regularly, the drainage will
flow downstream from the drains and this may lead to the mal-
function of pneumatic equipment.
In cases where the management of drain flushing will be difficult,
the use of filters with automatic drains is recommended.
For details on the qualities of compressed air, refer to SMC's "Air
Cleaning Equipment” catalog.

4. Types of air
Do not use compressed air containing chemicals, synthetic oil
which includes organic solvents, salt, corrosive gases, etc., as this
may cause damage or malfunction.
1. Do not operate in locations having an atmos-
phere of corrosive gases, chemicals, sea
water, fresh water or water vapor, or where
there will be contact with the same.
2. In locations which receive direct sunlight, the
sunlight should be blocked .
3. Do not operate in locations where vibration
or impact occurs.
4. Do not operate in locations near heat sources
where radiated heat will be received.
Operating Environment
Warning
1. Maintenance should be performed in accor-
dance with procedures in the instruction
manual.
Improper handling may cause damage or malfunction of equip-
ment or machinery.
2. Maintenance work
Improper handling of compressed air is dangerous. Therefore, in
addition to observing the product specifications, replacement of
elements and other maintenance activities should be performed
by personnel having sufficient knowledge and experience pertain-
ing to pneumatic equipment.
3. Drain flushing
Drainage should be flushed from air filter and other drains on a
regular basis. (Refer to specifications.)
4. Pre-maintenance inspection
When removing this product, turn off the electric power and be
certain to shut off the supply pressure and exhaust the com-
pressed air in the system. Proceed only after confirming that all
pressure has been released to the atmosphere.
5. Post maintenance inspection
After installation, repair or reconstruction, reconnect pressurized
air and electric power, and then perform inspections for proper
operation and air leakage. If the sound of air leakage can be
heard, or if the equipment does not operate properly, stop opera-
tion and confirm that it is mounted correctly.
6. Disassembly and alteration prohibited.
Do not disassemble the unit or make any alterations to it.
