① ① ① ① Install air filter
Install air filters close to valves at their upstream side. A filtration
degree of 5 μm or less should be selected.
② ② ② ② Install an air dryer, after cooler or Drain Catch(water
separator), etc.
Air that includes excessive drainage may cause malfunction of
valves and other pneumatic equipments. To prevent this, install an
air dryer, after-cooler, or water separator, etc.
③ ③ ③ ③ If excessive carbon dust is generated, eliminate it by
installing mist separators at the upstream side of
valves.
If excessive carbon dust is generated by the compressor, it may
adhere to the inside of valves and cause malfunction.
Refer to SMC 's " Air Cleaning Equipment " catalog for further
details on compressed air quality.

Operating Environment

Warning Warning
Warning Warning
① ① ① ① Do not use valve in atmosphere of corrosive gases, chemicals,
salt water, water or steam or where there is direct contact with
any of these.
② ② ② ② Products with IP65 enclosures (based on IEC529) are protected
against dust and water, however, threes products cannot be used
in water.
③ ③ ③ ③ Products compliant to IP65 satisfy the specifications by mounting
each product properly. Be sure to read the Specific Product
Precautions for each product.
④ ④ ④ ④ Do not use in an explosive atmosphere.
⑤ ⑤ ⑤ ⑤ Do not use in locations subject to vibration or impact. Confirm the
specifications in the main section of this catalog.
⑥ ⑥ ⑥ ⑥ A protective cover, etc., should be used to shield valves from
direct sunlight.
⑦ ⑦ ⑦ ⑦ Shield valves from radiated heat generated by nearby heat
sources.
⑧ ⑧ ⑧ ⑧ Employ suitable protective measures in locations where there is
contact with water droplets, oil or welding spatter, etc.
⑨ ⑨ ⑨ ⑨ When solenoid valves are mounted in a control panel or are
energized for extended periods of time, employ measures to
radiate excess heat. So than temperatures remain within the valve
specification range.

① ① ① ①
Perform maintenance procedures as shown in the
instruction manual.
If handled improperly, malfunction or damage of machinery or
equipment may occur.
② ② ② ② Equipment removal and supply/exhaust of compressed air
When eqipment is removed, first confirm that measures that
measures are in place to prevent dropping of work pieces and
run-away of equipment, etc. Then cut the supply pressure and
power, and exhaust all compressed air from the system using its
residual pressure release function.
Furthermore, in the case of 3 position closed center type valves,
compressed air will remain between valves and cylinders, and must
be exhausted similarly.
When the equipment is to be started again after remounting or
replacement, first confirm that measures are in place to prevent
lurching of actuators, etc., and then confirm that the equipment is
operating normally.
③ ③ ③ ③ Low frequency operation
Valves should be switched at least once every 30 days to prevent
malfunction.（Use caution regarding the air supply..）
④ ④ ④ ④ Manual override operation
When the manual override is operated, connected equipment will be
actuated. Confirm safety before operating.
Caution Caution Caution Caution
① ① ① ① Drain flushing
Remove drainage from air filters regularly.
② ② ② ②
Lubrication
In the case of rubber seals, once lubrication has been started, it
must continued and use turbine oil Class 1 (no additives), VG32.
If other lubricant oil is used, it may cause malfunction. Contact us
for suggested turbine oil Class 2(with additive), VG32.
