Keep your Swamp Cooler from becoming a Swamp Thing

Step 13 Plugging in

Place the electrode in the water and plug it to the power outlet inside the swamp cooler. I modified the outlet so continuous 120 vac is supplied to the ion generator (bottom outlet), while power for the pump (top outlet) is only on when the fan is on. There is a small tab that joins both top and bottom "hot terminal" of the outlet made to break off with pliers. By keeping the ion generator on all the time keeps the water clean and also allows the electrode to act as a "impressed current anode" to save the cooler from corrosion.
