2. Specific Product Precautions (3)
Warning
(1) Check the connection before cleaning.
Clean the fittings whilst the tubes connected and
the screws tightened.
Do not clean the fitting when the tube, union nut
and body are not assembled.
(2) Review the conditions before cleaning.
Make sure that the fitting material is not affected
or damaged by chemical solution, temperature,
and water pressure before use.
(3) Do not use a metal brush or tool which
damages or scratches the fitting.
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 cause the malfunction of
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
o
C or less, the
moisture 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.
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.
(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.
