  • Page 6: Safety Icons

    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 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 (14) 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. (15) Inserting fingers or objects into the motor inlet may result in electric shock, injury, or fire.
  • Page 9 Caution Maintenance and Repair Dispose in accordance with legislation for disposal and cleaning of waste products, handle as industrial waste, and do not incinerate. Toxic fluorine gas is generated by incineration of fluorine-based plastics. (10) If the pump ceases operation, turn power OFF (set switch to O) immediately to prevent accidents, remove the power cord from the wall outlet, and contact your dealer or the manufacturer for inspection and repair.
  • Page 10 Note Operation Use the pump within an ambient temperature range of 40°C. Use at high ambient temperatures will dramatically reduce the life of the pump. Back pressure at the outlet while the pump is starting may overload the motor. (10) The thermal protection relay operates when the pump reaches a very high temperature. Touching the pump in this condition may result in burns.

    5) When starting the pump, it may not start if the intake-side pressure is lower than the atmospheric pressure. Attach an atmospheric release leak valve between the pump intake pipe and vessel, and set the intake-side pressure to atmospheric pressure when starting the pump. After starting the pump, always close the leak valve.

  • Page 15: Precautions When Starting

    4.3 Precautions when starting 1) Starting in cold weather Cold weather will increase the viscosity of bearing grease and harden diaphragms, resulting in the pump being difficult to start. Follow the procedure below in such conditions. A) Turn the switch ON/OFF 2~3 times with the inlet open to atmosphere until the pump starts. If the pump still does not start, raise the ambient temperature to beyond 0°C.
