2-2 Air supply
Warning
1) Use clean air.
Do not use compressed air which contains chemicals, synthetic oils containing organic solvents,
salts or corrosive gases, etc., as this can cause damage or malfunction.
Caution
1) Install an air filter.
Install an air filter close to the upstream side of the valve. Choose the filter of 5
μm of filtration.
2) Install an aftercooler, air dryer or water droplet separator.
Do not use compressed air containing a lot of condensate, which can cause the operating failure of
the product and other pneumatic equipment. Install an aftercooler, air dryer or water droplet
separator.
3) Use the product within the specified fluid and ambient temperature range.
When operating at temperatures below 5oC, water in the circuit may freeze and cause breakage of
seals or malfunction. Corrective measures should be taken to prevent freezing.
For compressed air quality, refer to SMC catalog "Compressed Air Purification System".
2-3 Piping
Caution
1) Before piping
Before piping, perform air blow (flushing) or cleaning to remove any cutting chips, cutting oil, dust,
etc. from the piping.
2) Sealant tape
When installing piping or a fitting into a port, prevent cutting chips and sealant material from getting
inside the piping.
When a pipe tape is used, leave 1.5 to 2 thread ridges exposed at the end of the pipe.
