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 [12. Dimensions] (page
19) for necessary space.
5) Install vertically so that outlet of drain is facing downward. It cannot be used in horizontal or upward
direction as it may cause operation failure.
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.
6) Drain guide is not equipped with valve function. Be sure to connect piping for drain. No piping for
drain allows the drain and compressed air to exhaust freely. Also, the piping should be performed
with drain guide held by spanner to prevent breakage of bowl.
7) To make drain discharge piping for auto drain, connect pipes under the following conditions to avoid
malfunction. Tube with a piping internal diameter of ø6.5 (ø1/4") or above and a length of 5 m (200
inch) or less.
8) Pipework for auto drain discharge which rises higher than the auto drain outlet should be avoided. It
may cause the auto drain operation to fail.
