Installation
Warning
1) Do not drop or apply impact during transportation or installation. It will cause damage to the product
and result in operation failure.
2) Do not install in areas of high humidity or high temperature. Operation outside of the product
specification range may cause damage to the product or operation failure, or shorten the product life.
3) Connect the product ensuring the direction of arrow or "1"(IN) and "2"(OUT) ports for air direction or
an arrow. Incorrect connections may cause malfunction.
4) Install with adequate space for maintenance beneath the product. Refer to [11. Dimensions] (page
16) for necessary space.
Piping
Warning
1) Before piping, perform flushing or cleaning of the piping, etc. to remove any cutting chips, cutting oil,
solid foreign matter, etc. from the piping. Contamination of piping may cause damage or malfunction.
2) When screwing together pipes and fittings, etc., be certain that chips from the pipe threads and
sealant do not get inside the pipe. When a sealant tape is used, leave 1.5 to 2 thread ridges exposed
at the end of the threads.
3) Connect piping/fittings using the recommended torque while holding the female thread side tightly.
Insufficient tightening torque can cause loose piping or sealing failure. Excess tightening torque may
cause damage to threads. If the female side is not held while tightening, excessive force will be
applied to the bracket directly, causing breakage.
Recommended tightening torque (Unit: N m)
Thread size
3/4
1
Torque
28 to 30
36 to 38
4) Before screwing-in an SMC fitting or S coupler, please refer to "Tightening the threaded portion of
the connection thread" section of the Fitting & Tubing Precautions.
5) Do not apply torsion or bending moment other than the weight of the product itself. External piping
needs to be supported separately as it may cause damage. Non-flexible piping like steel tube is
susceptible to excessive moment load or vibration. Insert flexible tubes to prevent this.
