    Notes:
  

  

    1) Flow settings are calibrated using water @ +70°F on increasing flow, with
      units in a vertical position (lead wires up).
  

  

    2) Care should be taken by specifiers to ensure fluid compatibility with the
      above listed wetted materials.
  

  

    3) Use of 50 micron filtration is recommended.
