If bags are opened before the valves are ready to be connected to the pipes, the entry of foreign matter from the piping ports could cause the solenoid valves to fail or malfunction.
  • Page 5 INSTALLATION (Section 4.2) a) When installing a solenoid valve unit, never attempt to hold it in ！ WARNING : position by means of the pipes connected to it. Mount the solenoid valve by applying the mounting screws and/or mounting plate to the solenoid valve. b) Tighten the screws with proper torque.
  • Page 6 WIRING (Section 4.4) Be sure to turn off the power, before conducting any wiring opera- ！ WARNING tions. Also, do not touch or make the wet hands close to the termi- nal areas while they are energized. It may result in electric shock. a) Confirm the used voltage and polarities securely, when wiring.

(2) For installation at a site that has spatters in the air, select incombustible tubes or metal pipes.
  • Page 20 INSTALLATION (7) Tube connections Do not bend a tube immediately at where it is connected to the joint but lead it out straight from the end of the joint for a length equal to or greater than the outside diameter of the tube. The tension applied sideways through the tube should not exceed 40N (about 5N for C18, CL18 and CLL18).
