UNPACKING (Section 3) Bags containing solenoid valves should be opened only ! CAUTION : when you are ready to connect the valves to the pipes immediately afterward. If bags are opened before the valves are ready to be con- nected to the pipes, the entry of foreign matter from the piping ports could cause the solenoid valves to fail or malfunction. ...

f) Avoid using the solenoid valve system in a humid en- ! CAUTION : vironment because the humidity is likely to cause condensation with a change in the temperature. g) Do not use the normal type solenoid valves for an ap- plication that requires conformity with explosion-proof specifications. Choose explosion-proof solenoid valves instead. h) The packing and gaskets may deteriorate sooner than usual if used in an atmosphere with a higher than normal density of ozone (for example, the atmosphere near a beach or in an area with frequent thunder- storms). ...

PIPING (Section 4.3) a) M ake sure that the pipes will not be disconnected at the ! CAUTION : joints by mechanical movements, vibrations or tension. If the exhaust piping of the pneumatic circuit is discon- nected, the actuator speed control is disabled. If the above happens to a chuck holding mechanism, the chuck will open. The inadvertent opening of the chuck may cause a serious accident. ...

CAUTION : different from the specified conditions or if you intend to use the product for a special application, be sure to con- sult us about the product specifications before using the product. 4.1 Environment a) In a dusty environment, foreign matter may enter even ! CAUTION : through the exhaust port. The movement of the exhaust valve causes a respiratory action at the exhaust valve, which may cause inhalation of foreign matter near the exhaust port. This potential sit- uation would be worse if the exhaust port is facing up- ward. Attach a silencer to the exhaust port or have the exhaust port face downward. ...

5.3.1 Lubrication The MN4KB2 Series solenoid valve systems use pre-lubricated valves that usually do not require lubrication from the outside. If you have to lubricate a valve, use Type 1 turbine oil (ISO-VG32) without additives. Excessive lubrication and extremely low pressure may cause a longer re- sponse time.
