  • Page 6 Warnings EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury. • Do not operate the unit when fatigued or under the influence of drugs or alcohol. • Do not exceed the maximum working pressure or temperature rating of the lowest rated system com- ponent.

  • Page 7: Pressure Relief Procedure

    Pressure Relief Procedure Pressure Relief Flushing Procedure Follow the Pressure Relief Procedure when- ever you see this symbol. To avoid fire and explosion, always ground equipment and waste container. To avoid static sparking and injury from splashing, always flush at the lowest possi- ble pressure.

  • Page 8: Troubleshooting

    Troubleshooting Troubleshooting 1. Follow the Pressure Relief Procedure, page 7. 2. Check all possible problems and solutions before disassembling pump. PROBLEM CAUSE SOLUTION Pump does not operate. Insufficient power supply. Verify that power supply meets require- ments. See Performance Charts, page No flow rate input to VFD.
  • Page 9 Troubleshooting PROBLEM CAUSE SOLUTION Erratic flow or pressure. Pump cavitation; suction/supply line leak. Check and repair. Exhausted fluid supply. Refill and reprime pump. Restricted fluid supply to pump. Ensure all valves are fully open. Held open or worn ball check valves. Check and repair.
