2. Specific Product Precautions (3)
Air Supply
Warning
(1) Type of fluids
Please consult with SMC when using the product in
applications other than compressed air.
Regarding products for general fluids, please
contact SMC concerning applicable fluids.
(2) When there is a large amount of drainage.
Compressed air containing a large amount of
condensate can
pneumatic equipment. An air dryer or water droplet
separator should be installed upstream from the
filters.
(3) Drain flushing
If condensate in the drain bowl is not emptied on a
regular basis, the bowl will overflow and this may
cause the malfunction of pneumatic equipment. If
the drain bowl is difficult to check and remove,
installation of a drain bowl with an auto drain option
is recommended.
For details on the above compressed air quality,
refer to SMC's Best Pneumatics catalog.
(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.
Caution
(1) Install an air filter.
Install an air filter at the upstream side of valve.
Select an air filter with a filtration degree of 5μm or
finer.
(2) Install an after cooler, air dryer or water droplet
separator, etc.
Compressed air that contains a large amount of
drainage can cause malfunction of pneumatic
equipment. Therefore, take appropriate measures
to ensure air quality, such as by providing an
aftercooler, air dryer or water droplet separator.
(3) Ensure that the fluid and ambient temperature
are within the specified range.
If the fluid temperature is 5
in the circuit could freeze, causing damage to the
seals and leading to equipment malfunction.
Therefore, take appropriate measures to prevent
freezing.
For details on the above compressed air quality,
refer to SMC's Best Pneumatics catalog.

Operating Environment
Warning
(1) Do not use in an atmosphere having corrosive
gases, chemicals, sea water, water, water steam,
or where there is direct contact with any of
these.
Refer to each construction drawing on the fittings
and tubing material.
(2) Do not expose the product to direct sunlight for
an extended period of time.
of
(3) Do not use in a place subject to heavy vibration
and/or shock.
(4) Do not mount the product in locations where it
is exposed to radiant heat.
(5) Do not use the ordinary fittings and tubing in
locations where static electricity would be
problematic.
It may result in the system failure and trouble. In
such places, use of antistatic fittings (KA series)
and antistatic tubing (TA series) are recommended.
(6) Do not use the ordinary fittings and tubing in
locations where spatter is generated.
Spattering may result in a fire hazard. In such a
place, use of flame resistant fittings (KR/KRM
series) and flame resistant tubing
(TRS/TRB/TRBU/TRTU series) are recommended.
(7) Do not use in an environment where the
product is directly exposed to cutting oil,
lubricant, coolant oil, etc.
Please contact SMC if using for an environment
exposed to cutting oil, lubricant or coolant oil, etc.
(8) Take note that if nylon tubing, soft nylon tubing
and antistatic tubing are used in a clean room.
The antioxidant on the surface of the soft nylon
tubing may come off, thereby lowering the
cleanness level.
(9) Do not use in environments where foreign
matter may stick to the product or get mixed in
the product's interior.
This may cause leakage or disconnection of the
tubing.
