  • Page 6: Using The Pump Safely

    Using the Pump Safely To ensure that the pump is handled correctly, read this section thoroughly before use. This manual and the warning labels on the pump include safety icons as an aid to understanding safety requirements. These safety icons warn the operator and others of possible dangers and damage and should always be followed.

  • Page 7: 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. (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 8 Warning Operation (15) This pump is not designed to be explosion-proof. When using the pump, ensure that there are no inflammable materials such as solvents, or explosive gases, in the vicinity. Use under such conditions may result in injury or fire. (16) Inserting fingers or objects into the motor inlet may result in electric shock, injury, or fire.
  • Page 9 Caution Operation Do not use in applications involving organ transplants, or contact with body fluids or living tissue. Touching rotating components (eg motor, main shaft, axial joints, cooling fan) while the pump is in operation may result in injury. The overload protector operates when the pump becomes excessively hot. Touching it in this condition may result in burns.
  • Page 10 Note Operation (9) Ensure that the pump is used within an ambient temperature range of 7 - 40°C. Use at high temperatures will dramatically reduce the life of the pump. (10) Back pressure at the outlet while the pump is starting may overload the motor. (11) The thermal protector operates when the pump reaches a very high temperature.
