Be sure to read before handling.
Refer to front matter 43 for Safety Instructions.
Precautions on ON/OFF Valve
Mounting
Warning
Warning
1. If air leakage increases or equipment does not oper-
ate properly, stop operation.
After mounting is completed, confirm that it has been done cor-
rectly by performing a suitable function test.
2. Do not apply external force to the coil section.
When tightening is performed, apply a wrench or other tool to
the outside of the piping connection parts.
3. Avoid sources of vibration, or adjust the arm from
the body to the minimum length so that resonance
will not occur.
Piping
Caution
1. Preparation before piping
Before piping is connected, it should be thoroughly blown out
with air (flushing) or washed to remove chips, cutting oil and
other debris from inside the pipe.
Install piping so that it does not apply pulling, pressing, bend-
ing or other forces on the module unit.
Operating Environment
Warning
1. Do not use the product in a place where corrosive
gas, chemicals, brine, water and/or water steam are
present or can splash on it.
2. Do not use the product in a place with the explosive
atmosphere.
3. Avoid using the product in a place where vibration
or impact can occur.
4. Do not use the product in the vicinity of a heat
source or under radiant heat.
5. In locations where there is contact with spatter from
water, oil, solder, etc., take suitable protective mea-
sures.
Lubrication
Caution
1. This solenoid valve can be used without lubrication.
Maintenance
1. Low frequency operation
Switch valves at least once every 30 days to prevent malfunc-
tion. Also, in order to use it under the optimum state, conduct
a regular inspection once a half year.
2. Do not disassemble the product. Once the product
has been disassembled, SMC does not warrant
such product.
When it is required to disassemble the product, contact SMC
or SMC sales representative.
