Pentair iChlor Salt Cell: What Do all the Lights Indicate? A Video Guide

The Pentair iChlor is a great salt water system and the control panel is very user friendly. There are al ot of different lights and functions so to clear things up for you I made a short video going over all of the lights and functions.

The Status LED indicates the following on the iChlor Salt System.

Cell Status: Shows the status of the iChlor.
Green: iChlor is operating normally and producing chlorine.
No Light: iChlor is off and not producing chlorine. It may be in an off-period of the sanitizing cycle and
will return on shortly. This happens if the percentage is set to less than 100%. If you set it at 20% the iChlor will be running for 12 minutes every hour and off for 48 minutes. So the cell light will be off when it is not producing during that time. There is nothing wrong with the unit.

Red: iChlor is in “Standby” mode (system off, no chlorine production) due to a cold water condition. The iChlor will resume to normal operation mode, including salinity report, once water temperature rises above 52° F (11° C). In this mode, the display will read “COLD” to indicate the condition. The salt cell will not function or produce salt in water temperatures below 52° F (11° C).
Short Red Flash: Unit has detected a malfunction on the temperature sensor, and will indicate it with
short red flashes either while the cell is off (LED off), or while the cell is ON (Green LED). The unit will
continue normal operation, but salinity indication might not be accurate until flow switch is replaced.

Green (Flashing): iChlor needs to be inspected. The blades may have calcium buildup or any other
condition that cause a lack of conductivity. The iChlor is not producing chlorine.
In this mode, the display will read “CELL” to indicate the condition. Clean the salt cell at this time to remove the calcium build up.

Flow Status: This light indicates the status of water flowing through the iChlor.
Red: Insufficient water flow through the iChlor, no chlorine is being produced.
Green: Sufficient water flow to produce chlorine.
Short Flickering: Short flickering: iChlor is in communication with an IntelliFlo pump, and it is monitoring
the pump status. This short flickering will be present as long as there is communication with the pump,
either with no flow (RED FLOW LED) or with good flow (GREEN FLOW LED).

Here is what the Salt Level LED Light indicates.
Green LED: Good salt level. The pool water salt level is between 3000 ppm and 4500.
Green LED (Flashing): Salt level is above 4500 ppm. The salt level is too high
Red LED: Low salt. The salt level is between 2600 ppm and 3000 ppm. Ithe iChlor will stillproduce chlorine but at a reduced level.
Red LED (Flashing) Very low salt. The salt level is between 2000 ppm and 2600 ppm. The iChlor
will produce chlorine at a very reduced rate.

Red LED (Flashing): Not enough salt. The salt level has fallen below 2000 ppm. The iChlor will not produce chlorine.

Digital Display Overview:
The iChlor Display shows the “output %” and cell polarity, while it is operating.

To adjust output percentage simply press either LESS or MORE button. If your iChlor is connected and controlled by a Pentair Automated system you will not be able to adjust the output from the cell, only from the automated system settings or the app.

Once the output begins to flash on the digital display, this indicates that the iChlor is ready to change output levels. While output is flashing, press LESS or MORE button, to change output in 1% increments.

Note: Press and hold LESS or MORE button to change output in larger increments (5% jumps).

Once the desired setting is programmed and you stop changing the setting, the digital display will stop flashing after a few seconds.

The last setting after the digital display stops flashing will be the new set output level.

Cell polarity indicator:
Cell polarity is displayed as a small rotating character on the left side of the output % display. Clockwise rotation indicates Forward polarity on the blades. Counterclockwise rotation indicates Reverse polarity on the blades. The rotating feature also indicates chlorine production. If the cell is OFF, the character will not be displayed.
