Mounting
1. Operation manual
Install the products and operate them only after reading
the Operation Manual carefully and understanding its
contents.
Also keep the manual where it can be referred to as
necessary.
2. Maintenance space
The installation should provide with sufficient space for
maintenance activities (removal of valve, etc.).
3. Observe the tightening torque for screws.
Tighten the screws to the recommended torque for
mounting the product.
4. If air leakage increases or equipment does not
operate properly, stop operation.
Check mounting conditions when air and power supplies
are connected. Initial function and leakage tests should be
performed after installation.
5. Painting and coating
Warnings or specifications printed or affixed on the
product should not be erased, removed or covered up.
Please consult with SMC if paint is to be applied to
resinous parts,
Piping
1. Before piping
Before piping, it should be thoroughly blown out with air
(flushing) or washed to remove chips, cutting oil and other
debris from inside the pipe.
2. Wrapping of pipe tape
When screwing piping or fittings into ports, ensure that
chips from the pipe threads and sealing material do not
get inside the valve.
Also, when the pipe tape is used, leave 1.5 to 2 threads
ridges exposed at the end of the threads.
4. Connection of fittings
When screwing fittings into valves, tighten as follows.

Wiring
1. Applied voltage
When electric power is connected to a solenoid valve, be
careful to apply the proper voltage. Improper voltage may
cause malfunction or coil damage.
2. Confirm the connections.
After completing the wiring, confirm that the connections
are correct.
Lubrication
Lubrication
1) The product has been lubricated for life at manufacturer,
and does not require lubrication in service.
2) If a lubricant is used in the system, use turbine oil Class
1 (with no additive), ISO VG32. Once a lubricant is used
in the system, lubrication must be continued because
the original lubricant applied during manufacturing will be
washed away.
When turbine oil is used, refer to its Material Safety
Datasheet (MSDS).
3) Please contact SMC regarding Class 2 turbine oil (with
additives), ISO VG32.
