  • Page 12: Precautions

    Refer to Safety Data Sheets (SDS) precautions from your solution supplier. Water Pre-Prime All LMI pumps are pre-primed with water when shipped from the factory. If your solution is not compatible with water, disassemble the Pump Head Assembly. Thoroughly dry the pump head, valves, O-rings, balls and diaphragm.
  • Page 13 PRECAUTIONS Back Pressure/Anti-Syphon Valve If you are pumping downhill or into low or no system pressure, a backpressure /anti-syphon device should be installed to prevent over pumping or syphoning. Contact your LMI distributor for further information. Electrical Connections WARNING: To reduce the risk of electrical shock, the metering pump must be plugged into a properly grounded grounding-type receptacle with ratings conforming to the data on the pump control panel.
  • Page 14 PRECAUTIONS Flow Display The accuracy of the flow value as shown on the pump display is highly dependent on the specific application. Calibration is necessary in order to display an accurate measure of the flow. Spills CAUTION: Spills of Dangerous chemicals should be cleaned up immediately.

  • Page 17: Installation

    Consult your distributor for additional information. Your LMI metering pump must be mounted so that the suction and discharge valves are vertical. NEVER posi t i on pu m p head and fi t t i ngs hor i zont al l y.

  • Page 18: Flooded Suction

    When pumping downhill or into a low or no pressure system, a backpressure / anti- syphon device should be installed to prevent over pumping or syphoning. Although popular for all solutions, LMI recommends flooded suction installations for all high-viscosity fluid applications.

  • Page 19: Tubing Connections

    INSTALLATION 3.3 Tubing Connections Use only LMI supplied tubing with your pump, as the tubing is specifically designed for use with the pump fittings. Before installation, all tubing must be cut with a clean square end. Valve and head connections from the factory are capped or plugged to retain pre-prime water.
