  • Page 17: Before Use

    1. Before Use “Strictly observe the following points.” Operators and maintenance service staff must read the instruction manual thoroughly before using the products. Do not operate the pump system unless all of the contents in the manual are completely understood. Caution Turn off the power supply.
  • Page 18 • The pump can be operated outdoors, as the pump employs a simple water and dust proof structure. When installing the pump, avoid places exposed to direct sunlight or direct rain with an ambient temperature of above 40ºC, or with a relative humidity of above 85%.
  • Page 19 • Arrange grounding! Do not operate the pump without connecting the grounding wire. Other wise, an electrical shock may result. Make sure the grounding wire is connected with the grounding terminal. • Limited operating site and storage Do not install or store the pump in the following places: Places where a flammable gas or material is used or stored.

  • Page 20: Installation, Piping, And Wiring

    3. Installation, Piping, and Wiring Installation z Installation Install the pump at a place where the ambient temperature does not exceed 40ºC and the relative humidity does not exceed 85%. (There should be no dew condensation inside the control unit.) The place should be convenient for future maintenance and inspection.
  • Page 21 Piping z Piping of pump fittings tube For discharge side and suction side piping, use the tube provided. The connections should be firm enough to prevent liquid leakage or air suction.
