2. Specific Product Precautions (3)
Cleaning
Warning
(1) Check the connection before cleaning.
Clean the fittings whilst connected to the product.
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.
Air Supply
Warning
(1) Type of fluids
Please consult with SMC when using the product
in applications other than compressed air and
water, steam. 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
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.
cause the malfunction
oils including organic
(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.
(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
of
problematic.
It may result in the system failure and trouble. In
such places, use of antistatic fittings (KA series)
and antistatic
recommended.
(6)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.
(7)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.
Warning
(1) Perform maintenance inspections according to
the procedures indicated in the operation
manual.
If handled improperly, malfunction and damage of
machinery of equipment may occur.
(2) Maintenance work
If handled improperly, compressed air can be
dangerous. The assembly, handling, repair, and
element replacement of pneumatic systems
should be performed by a knowledgeable and
experienced person.
(3) Drain flushing
Remove drainage from air filters regularly.
