How to Clean a Pentair Intellichlor Cell

The Pentair Intellichlor cell turns ordinary salt into chlorine on a continual basis to keep your pool clean and sanitary. The Pentair Intellichlor cell keeps track of salt levels, chlorine output, pool temperature and cleanliness. With time and use, the Intellichlor cell can accumulate minerals that are naturally present in the pool water. Regular cleaning with muriatic acid is necessary to prevent damage to the cell. The Intellichlor's diagnostic system informs you when the cell requires cleaning.

Step 1

Unplug the communication cable from the power center. If your system is connected to the load center, unplug the cable from the load center.

Step 2

Turn off the system pump and unscrew the unions on each end of the Intellichlor cell. Remove the cell from the plumbing system.

Step 3

Place the o-ring from the cleaning kit inside the washer. Place the washer inside the cap and screw the cap onto the Intellichlor cell.

Step 4

Fill a bucket with 1 gallon of tap water. Carefully mix in 1 quart of muriatic acid.

Step 5

Place the Intellichlor cell vertically in the bucket, cap-side down. Pour the muriatic acid carefully into the cell until the blades are covered. Allow the cell to sit in the acid solution for up to 30 minutes, until the bubbling stops.

Step 6

Pour the muriatic acid back into the bucket. Rinse the Intellichlor cell thoroughly with tap water.

Step 7

Remove the cap from the Intellichlor cell and place it back into its original position. Screw the unions back into place and plug in the connector cable.
