Please note: Part number change from 3004046 to 3004146 is because Refco added a ground wire to the power wiring harness and removed a wire from the alarm relay wiring harness that was not being used.

If a previously installed 3004046 Combi needs to be removed, a contractor will need to also remove the present wires and replace them with the wires provided with the new part number Combi.

Our engineering department felt that grounding the pump would make the sensor and pump even more reliable.
