Does not meet explosion-proof specifications. Please use only in non-explosion proof areas. . When using in an explosion-proof area, please select explosion-proof equipment. . Please use a low-power-consumption solenoid valve if you plan to keep the solenoid valve energized for extended periods of time. Please refer to page 26 for details. . Using equipment in a solvent atmosphere may result in diminished product quality, so please check the specifications and materials of the model. . When using equipment at high temperatures or in a solvent atmosphere, please check the specifications (operating temperature, materials, etc.) of the model before using.
