Electro-pneumatic Regulator Precautions
Be sure to read before handling.
Piping
Caution
1. Preparation before piping
Before piping, air blow (flush) or wash thoroughly to remove
chips, cutting oil and other impurities from inside the piping.
2. Wrapping of sealant tape
When connecting pipes and fittings, etc., be sure that chips
from the pipe threads and sealing material do not get inside the
regulator.
Further, when sealant tape is used, leave 1.5 to 2 thread ridges
exposed at the end of the threads.
Operating Environment
Warning
1. Do not operate in locations with an atmos-
phere of corrosive gases, chemicals, sea
water, water or steam, or where the same
substances will adhere to the regulator.
2. Do not operate in locations where vibration
or impact occurs.
3. In locations under direct sunlight, provide a
protective cover, etc.
4. In locations near heat sources, block off the
radiated heat.
5. In locations where water, lubricant or spatter
from welding, etc. will adhere to the
regulator, implement suitable protective
Air Supply
Warning
1. This regulator is designed for use with
compressed air. Contact SMC if any other
fluid will be used.
2. Do not use compressed air that includes
chemicals, synthetic fluids containing organic
solvents, salinity, or corrosive gases, since
this can cause malfunction.

Handling of One-touch Fittings
Caution
1. Tube attachment/detachment for One-touch fittings
1) Attaching a tube
1. Take a tube having no flaws on its periphery and cut it off
at a right angle. When cutting the tube, use tube cutter TK-
1, 2 or 3. Do not use pliers, nippers or scissors, etc. If
cutting is done with tools other than tube cutters, the tube
may be cut diagonally or become flattened, etc. This can
make a secure installation impossible and cause problems
such as the tube coming loose after installation or air
leakage. Allow some extra length in the tube.
2. Hold the tube and push it in slowly, inserting it all the way
into the fitting.
3. After inserting the tube, pull on it lightly to confirm that it will
not come out. If it is not installed securely all the way into
the fitting, this can cause problems such as air leakage or
the tube pulling out.
2) Detaching a tube
1. Push in the release button sufficiently. When doing this,
push the collar evenly.
2. Pull out the tube while holding down the release button so
that it does not snap back. If the release button is not
pressed down sufficiently, there will be increased bite on
the tube and it will become more difficult to detach it.
3. When using the removed tube again, cut off the portion
which has been chewed before reusing it. If the chewed
portion of the tube is used as is, this can cause problems
such as air leakage or difficulty in removing the tube.
2. When mounting a One-touch fitting, use a suitable wrench to
tighten the hexagonal flats of the fitting.
Moreover, position the wrench at the lower part of the
hexagonal flats as close to the threads as possible. When a
wrench of the proper size for the hexagonal flats is not used, it
will damage the hexagonal flats.
3. Tightening of M3, M5, and M6 connection threads
1) M3
After tightening by hand, tighten an additional 1/4 rotation with
the correct tool.
2) M5 and M6
After tightening by hand, tighten an additional 1/6 rotation with
the correct tool.
Overtightening can cause damage to the threads and/or air
leakage due to deformation of the gasket. Undertightening can
cause loose threads and air leakage, etc.
Precautions on Tube by Other Manufacturers
Caution
1. When using tubes by manufacturers other than SMC, confirm
that the tube's outside diameter tolerance satisfy the following
specifications.
±0.1mm or less
1) Nylon tubing:
±0.1mm or less
2) Soft nylon tubing:
3) Polyurethane tubing: +0.15mm or less,
-0.2mm or less
Do not use a tube if the outside diameter tolerance is not
satisfied. It may not be possible to connect the tubing, or
leakage or disconnection may occur after connecting.
