    4. Tighten all motor bolts. Float control installation ITT supplies several different float controls. Refer to the float control installation instructions provided with the controls for the proper installation procedure. This topic describes the Square D 9036 Simplex and Square D 9038 Duplex float controls.
  • Page 26 Installation How float controls work The on and off levels of the Square D 9036 simplex and the Square D 9038 duplex are controlled by adjusting the collars (335). As the liquid level rises, the float rises to contact the upper collar and the upward movement of the float rod causes the mechanical switch inside the control to close.

  • Page 27: Install The Square D 9036 Simplex And 9038 Duplex Float Controls

    Installation Float ball switches Float balls are individual switches that are used in multiple configurations to control the pump circuit. The float balls are suspended in the sump to the desired control level. When the fluid level rises to the float ball, the switch begins to float. The float is either anchored to a pipe or weighted.

  • Page 28: Piping Checklists

    Installation You must maintain the radius (4) between the float switch column and the float. Figure 13: Radius between float switch column and float Piping checklists General piping checklist Precautions WARNING: • Risk of premature failure. Casing deformation can result in misalignment and contact with rotating parts, causing excess heat generation and sparks.
