This pump is only for vacuum pumping, and may malfunction or cause accidents if not handled appropriately. Read the manual thoroughly, and pay due attention to inspections, maintenance, and safety.

  • Page 7: Checks When Opening Packaging

    4. Use ventilation holes, and fit a cooling fan, to reduce the temperature in the vicinity of the pump. Ensure that the pump cooling fan inlet is not blocked. Ensure that a space of at least 100mm is available on all sides of the pump. DOP-301SB DOP-301SVB...

  • Page 8: Using The Pump Safely

    0.2 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 9: 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 evacuate explosive gases. (2) In addition to discharge of gas via the pump outlet, gas may leak from the pump itself. Use it only with clean air at normal temperature, or gases of equivalent characteristics.
  • Page 10 Warning Power Supply (10)When attaching the main power cord to the pump, please use the power cord which meets the rated voltage and current, pursuant to the provision. 4-Core-cable(Size of the wire lead: 1.0mm or larger, 300V or more, 10A or more, 100°C or higher, one earth cable included) Ensure that one of the core wires is used as an earth wire.
  • Page 11 Caution Installation (1) To prevent back injuries, always use at least two people when lifting and moving the pump. (2) Microscopic particles resulting from wear of components are discharged from the outlet and contaminate the room. If necessary, connect a pipe from the discharge outlet to the outside of the building.
  • Page 12 Caution Maintenance and Repair (9) If the pump ceases operation, switch off the main power supply immediately to prevent accidents, remove the power cord from the wall outlet, and contact your dealer or the manufacturer for inspection and repair. (10)After stopping the pump, leave it for 30 minutes or more and begin work on it only after checking that it has cooled sufficiently.
