1. Unplug the softener from the outlet.
2. Remove the top cover:
a. On the back of the unit, unhook the two clips that hold the cover onto the tank below (Figure 1). Flex/pull the cover out and away from the softener at these clips.
b. There are two similar clips holding the front of the cover on as well. Slide the cover towards you to release these clips, being careful not to disconnect any wires. (Figure 2). It is normal for the plastic cover to produce some noise as it shifts and bends.
3. Under the lid, locate the control board and wires. You will see a red plastic connector with 5 wires attached to it: red, white, black, orange, and green.
4. Remove the red connector from the control board, flip it around, and reconnect. The red connector should cover the metal prongs completely, sitting flush with the white piece on the control board. The wires should be running away from the board.
5. Return the top cover to the unit and plug the power into the outlet.
