Thermal Protection
Run 3-phase motors through a control panel for thermal protection.
Single-phase motors are a continuous-duty type equipped with an automatic resetting heat sensor and may
restart unexpectedly. Heat sensor opening is an indication of motor overloading/overheating, which must
be corrected to extend the life of the pump. Refer to
“Troubleshooting” on page 9 for further details.

Risk of personal injury or damage to pump or other equipment.
• This pump is equipped with a cutting mechanism that has very sharp edges. Use caution when
working on or near these parts. Do not allow anything to enter the pump during testing.
• The float or ball portion of the switch must not be obstructed by the pump, the walls of the basin,
the plumbing, or any wiring in the basin as it floats up or down. Contact with obstacles may cause
the pump to continue running without water or to stop running when water is present, damaging
the pump or other property.
• Do not run pump dry. If run dry, the surface of the pump will rise to a high temperature that could
cause skin burns if touched, and will cause serious damage to the pump.
