Occasionally the salt indicator on the Pentair Intellichlor will not match the actual salt level of the pool. If this is the case, the salt level on the cell will need to be recalibrated. The following steps will provide a guide on how to recalibrate a Pentair Intellichlor. Note: This guide is only intended for versions 1.9 and below. Newer versions can not be recalibrated.

 

Step by Step

Top

Step 1

If the Intellichlor has been in operation for a few weeks, remove and acid clean the salt cell before field recalibrating. This will give the most accurate starting point.

Step 2

Manually test the salt level with salt test strips or an electronic salt tester. If the salt level is in the proper range of 3000-4200, proceed to step 3. If not, adjust the salt level to the proper parameters before recalibrating.

Step 3

With the pump running, verify the "Flow" light on the cell is green. This indicates good water flow through the cell. 

Step 4

Press and hold the "More" button for 3 seconds to enter system status mode. All the lights will scroll across the panel, and then go dark. Only the "Power", "Cell", "Life", and "Low" lights will be lit.

Step 5

After a few moments, the "Good", "Add", and "Low" salt lights will begin to scroll, indicating the salt level is being read. It may take up to one minute to read the salt.

Step 6

The salt scrolling will stop and one of the salt lights will be displayed. The "Sanitizer Output 20%" light will turn on to indicate changes are now allowed. Press the "More" button to cycle through each salt level, and then press the "Less" button to choose and save the display as the new salt level. The "PWR", "Cell", "Life", and "Flow" lights will flash 4 times, then the mode exits to normal.

Step 7

The unit is now recalibrated to the salt level of the pool. The display will now be normal, showing the output percentage, flow status, etc. The field calibrate mode will exit in 5 seconds if no buttons are pressed.

I did everything for the reset, including cleaning the cell and it is still showing 9900.

Where do you see 9900 ppm on the cell? The Intellchlor does not have a readout display, just a light dashboard that will begin to flash if the ppm goes above 4200.

I have the app on my phone, didn’t think about checking the panel.

I would also get the water tested by a local pool store just to confirm the readouts you are receiving from your equipment is accurate.

My low salt light is on. I have run a diagnostics on my easy touch unit and it reads 2100ppm but I have had the salt tested at the pool store and it is 3000ppm. Any suggestions?

You should clean the cell to determine if that may be providing a false fault code. Scale buildup can prevent your cell from getting a good reading.

My salt cell is showing 2100 PPM while the actual reading is 3100. I have cleaned the cell as you suggested but problem remains. Any further suggestions?
 Reply

If you have already recalibrated and cleaned the cell without any success, I am afraid the cell is probably in need of being replaced. Because of the Intellichlor's design, all the crucial sensors and computational elements are in the cell. When one of them starts to fail, your cell is running on borrowed time.

My new Salt Cell was installed today. The red flashing low salt indicator is on. My pool actually tested above 4500 yesterday. How long until it calibrates and sees the high salt level?
 Reply

InyoPools Product Specialist  Posted: 9/3/2020 

Give it a few minutes. But why are you waiting for it to provide a reading that is out of its range? Lower the salinity, because whether it is low or high, the cell is not going to work.

Intellichlor ic 40 Pool guy added salt yesterday read good for about 10 hours now it reads low this keeps happening over and over again any suggestions out there

The first things that need to be known, how old is the cell, and when was the last time the cell was cleaned? Also, what troubleshooting have you already done so far?

My swimming pool has only had water in it For two months everything is brand new I check the levels periodically seems low on chlorine every time. Is it possible I need to clean the salt cell already I know my filter was pretty bad when I cleaned it out For the first time

Salt systems usually have a "clean cell" alert programmed to pop-up every 500 hours of use. This alert pops up whether the cell needs it or not. But if your cell is flashing a warning, it never hurts to give a chemical soak. Does your salt system have an output control? Most systems have a knob or someplace in the UI settings to adjust chlorine output. If you can, I would increase it. What are your other water chemistry results? CYA, TA, pH, and such.

I have a Pentair Intelichlor. It has no power going to it. It was working fine and when I went to backwash the pool I noticed that there were no lights on the intelichlor... Is there a fuse that I can check? It was just replaced last season.
 Reply

InyoPools Product Specialist  Posted: 9/1/2020 

there is a fuse on the Intellichlor's power center. The fuse (p/n - 521248Z) is the little black knows shown at the bottom of the power center.

I replaced my unit a year ago... produces chlorine just fine and all the lights are green. My problem is that on the on the pentair app it only shows 0% ppm salt... not sure what to do... any help would be appreciated.

Unfortunately, I am not familiar with the Pentair app; but if the cell lights are green, you should be alright. You should contact Pentair's tech support for troubleshooting instructions for your app.

My intelliclor does not have any lights is there a reset button somewhere
 Reply

InyoPools Product Specialist  Posted: 10/23/2020 

The Intellichlor does not have a reset button; have you checked that the Intellichlor power supply is receiving power from the breaker and output voltage to the cell?

I have a new IC40 cell and salt in my pool but the red/green light flashes under salt level and the red light is on under flow. Motor is on and temperature is reading at 70. Need assistance.

When we first installed an Intellichlor, we had a few blinking lights on the initial start-up for a few minutes. After the initial boot up, the cell worked fine.Do you have a variable or dual-speed motor operating on a lower RPM? This might be the thing triggering the "Low Flow" alert.

All of my levels tested good and the lights are all working as they should but the MORE & LESS buttons do nothing when they are pressed, either individually or together. Any ideas? Thanks, T

Your cell's user interface may be bad; whether from age or compromised by water. unfortunately, those interface panels are not a replaceable item and generally require the whole cell to be replaced.

I’m having same issues. I cleaned and still showing cell light flashing. Tried recalibration but it did not go through the cycling of salt lights. What else can I do?
 Reply

InyoPools Product Specialist  Posted: 7/3/2019 

How old is the cell? If it is a few years old, it is likely just old and needs to be replaced.

After cleaning the cell on my IC40, the green salt light continues to flash. The salt level in the water tests fine. Any thoughts on how to get back to solid green? It was working great before cleaning.
 Reply

InyoPools Product Specialist  Posted: 7/2/2019 

Did you already try recalibrating it?
 Reply

 Posted: 4/14/2020 

i have the IC60 high salt is flashing but did the salt test and its good i calibrate but still the same flashing green light
 Reply

I suggest checking the cell for calcium build-up and perform a thorough cleaning. Scale build-up is he usual cause for this alert
 Reply

 Posted: 7/2/2019 

After letting it run for 24 hours, it reset to solid green so all is good. Thanks
 Reply

 Posted: 5/10/2019 

Thanks, I just did this and my cell light turned on to green. I will let you know if it starts producing chlorine and if I saved $600.

How can I tell what version of my IC40 I have? Thanks.

InyoPools Product Specialist  Posted: 5/10/2019 

Does your cell's light display resemble the examples shown in this guide? Or is the order or grouping different?
 Reply

intellichlor ic40 replaced flow switch. Salt level light is red for couple of minutes and then turns off. All other lights are good/green. Salt level is also good...added a bag over the past week.

I’ve had same problem and can’t find ANYONE who has ever heard of this problem. Any ideas?
 Reply

Since the cell eventually does revert to normal chlorination, I wouldn't be too concerned. But to be on the safe side, I would clean the cell with muriatic acid. If the cell is having issues getting salt readings, it is a sign of a dirty or worn cell.

After cleaning my cell, high salt light is flashing and panel reading is 9900 and I don’t think it is generating chlorine. Salt levels in pool are good and all other status lights are correct. It was working fine before cleaning. Version 2.02. Any suggestions?
 Reply

 Posted: 4/26/2020 

Were you ever able to fix this? Mine is doing the same thing 9900 PPM high salt. IC60 rev3110. Cell is clean. No calcium build up. All lights are good except high salt blinking green even though salt level is fine.
 Reply

InyoPools Product Specialist  Posted: 3/25/2019 

Version 2.02 cannot be recalibrated. The issue is either the cell or the flow switch. Most people start by replacing the flow switch since it's much cheaper and a common cause for a faulty salt reading.
