NOTE: The motor in this unit contains thermal protection that responds to motor current and heat from the motor winding and ambient
temperature. When the combination of current and heat exceeds a predetermined point, the protector opens and interrupts the circuit.
When the winding termperature returns to a more normal level, the protector will automatically reset.
