  • Page 8: Cautions For Safety In Use

    ・ Cautions for Safety in Use Danger Applications (1) This pump is not designed to be explosion-proof, and should therefore not be used to discharge explosive gases. Such use may result in injury and fire. (2) In addition to discharge of gas via the outlet, gas may also leak from other parts of the pump, and it should therefore not be used with toxic gases.
  • Page 9 Warning Power Supply (5) Always check the pump and install wiring with the power cord disconnected. Working with power connected may result in electric shock, or the pump starting unexpectedly. (6) Ensure that wiring is installed by persons qualified in accordance with regulations for wiring (e.g. technical standards for electrical equipment, requirements for internal wiring).
