Pentair IntelliChlor IC20 Salt Generator Replacement Cell

IntelliChlor® Salt Chlorinator uses common table salt to produce all the chlorine a pool needs, safely, effectively, and automatically. Same sanitation performance as manual chlorine addition without the drawbacks. No need for customers to buy, transport and store chlorine compounds.

Electrolytic chlorine generation (or salt chlorine generation) with IntelliChlor Salt Chlorinator is the easiest, most effective, and convenient way to keep your pool water sparkling clean and sanitized. The IntelliChlor Salt Chlorinator uses table salt to produce all the chlorine your pool needs, right in your pool - safely, effectively, and automatically.

An Eco SelectChoice: Using only natural table salt, the IntelliChlor Salt Chlorinator automatic chlorine generator creates pure chlorine in the pool and eliminates the need to buy, store, and add harsh chlorine products manually. In effect, fewer resources are used in the production, packaging, and transportation of these chemical compounds.

Can I use a 40k on a 18k gal. Pool?
Daniel P on Aug 29, 2017
BEST ANSWER: Sure, why not? I use one on a 9000 gallon pool. It should last longer than the smaller unit.
What is the current retail price of the Pentair salt cell IC-40?
A shopper on Jun 4, 2016
I have a 10,500 gallon pool and run the pump about 10 hours a day in Houston summer heat. What sanitizer output setting should I expect to use under normal operation to maintain proper chlorine level?
Nick P on Aug 19, 2017
BEST ANSWER: I live in central Arkansas and have a 16,500 gallon pool and run it 12 hours per day at 100 percent during the summer months
Purchased a replacement earlier this year. Will Pentair take the old unit and rebuild it? Seems like a waste to throw it in the garbage.
A shopper on Jul 15, 2016
BEST ANSWER: As far as I know they do not take them back. I usually recommend people keep the old cells to use as a pass through for any time the pool is not chlorinating. It basically becomes a winter/dummy cell.
how long does the salt cell last?
A shopper on Sep 22, 2015
BEST ANSWER: There is actually an industry standard based on hours and percentage you have for generating rate.

My first generator lasted approx. three seasons at which I ran the pump 12 hours per day from April thru October at 60% generation rate. I also did not clean it as recommended. My new generator is in its' second season and generate 8 hours per day at 60 to 80% from April thru October. My best guess will be 4+ years. I clean it every 3 months of operation. As an aside our pool is 10,000 gals.
What comes in the box ?
Ismael Z on Aug 28, 2016
BEST ANSWER: Everything you need comes with it. They even include new fittings for the pipes but if you are just switching it out you do not need these. Unscrew and unplug the old one and then screw the new on in place and plug it in. It is that easy.
What do I do when light is flashing to "inspect" the cell??
Vernon R on May 14, 2018
BEST ANSWER: If you have not cleaned the cell in 4 months or longer, you may want to soak the cell in a muriatic acid/water solution (1 part Muriatic to 3 parts water}. Also, if the pool water is below 52 degrees, the cell probably will not produce chlorine. Lastly, if your cell is getting to be 7 - 10 years old, it may be time to replace it.
Do I need a power source if I have an easytouch system, or do I just plug it into the easytouch?
Grant B on May 16, 2016
BEST ANSWER: When I bought the Pentair IntelliChlor Salt Generator Replacement Cell | 20,000 Gallons I just plug it in to the transformer of the old unit and when I started it up it started up just fine the plug is the same plug as the old unit and plugs right in the transformer and thats where it gets its power
Shipping time to florida?
A shopper on Aug 8, 2019
Do i need to bring this salt cell into my house during the winter or can it stay hooked up to the filter during the cold months?
A shopper on Oct 31, 2017
Is the plug compatible with IntelliChlor chlorine generator power center?
Donna on Apr 27, 2016
BEST ANSWER: It is a plug and play. remove the 2 couplings unplug and remove old generator then replace with new and plug in shouldn't take more than 15 minutes.
Can I just swap out the present IC20 with a new one? Do I have any adjustment to make? Would you forward instructions with new unit? A quick response will be appreciated
Laurrel W on Jan 23, 2016
BEST ANSWER: Yes, just unplug and unscrew the old unit and put in the new one just as the old one was. Plug in the new unit and start the pump.
How much is installation?
Dennis B on Apr 18, 2019
BEST ANSWER: The only cost was for the cell you can install your self, if you are asking about the system I did a 58000 gal pool and a 3000 gal spa at the cost of about $7,000 pluming cells.
Does it come as pictured with replacement unions and nuts?
A shopper on May 18, 2016
BEST ANSWER: Yes it does. However, there is one thing that you will notice when you get it. The display/control panel will be upside down from the way your original is. It's a manufacture thing I guess.
Hope this helps
It looks like my cell is no longer working after 3 years. No light on Status of cell. Can I just order a replacement cell and replace it myself. Do I need a professional to replace it. Do I have to do any special adjustment?
Laurrel W on Jan 21, 2016
It just screws in Easy to replace by yourself.
Just opened pool. 1 season chlorinator flashing "cell". Temp is 45 degrees. Do we need to wait for water to warm up?
A shopper on May 16, 2020
BEST ANSWER: The manual says the unit switches off and will not produce chlorine in water temperatures of 52° and below. If the CELL light is flashing green, the manual says that means one of three things: 1.) check salt level, 2.) cell has calcium build-up and requires cleaning, or 3.) check water chemistry and balance. Hope this helps!
I don't understand one thing. The information above says "Complete Intellichlor Salt Generator requires purchase of Power Center and one Salt Cell (IC20 or IC40). I am replacing a dead one, but why does this say i need to purchase a Salt Cell. Isn't that what this is?
A shopper on May 14, 2018
BEST ANSWER: The power center should be mounted on a wall, connected to a chlorine generator (cell) in the piping. If your cell only has gone bad, that's all you need to replace. The nomenclature is confusing, but a Salt Cell is merely a chlorine generator that is self-contained. Mine is the IC20 model. The power center is a completely separate item.
My salt cell has no power. Does the flow switch determine power?
Sam W on Jun 1, 2021
BEST ANSWER: No the flow switch does not control power. The flow switch only controls chlorine production. If no flow, the flow switch stops chlorine production. The cell receives its power from a small transformer that may be in your main panel or located near the panel depending on the installation. Follow the black cord from the cell back to where it is plugged in.
Is the ic-20 big enough for 16 by 32 pool deep end 8 foot?
A shopper on Jul 31, 2018
BEST ANSWER: The ic-20 isn't really good for any size pool unless you like spending money on replacements. I have gone through 3 of these in the last 5 years. The warranty is usless.
Which Pentair Model do I need for a 13,00 Gallon pool?
Sara L on Sep 8, 2016
BEST ANSWER: They come in sizes which represents the gallons of water your pool holds. Sizing is IC 15, 20, 40, 60. I have 17,500 gallons so I purchased the 20. If Sara has 13,000 gallons the 15 would work for her.
When I turn the pool puump on ,the salt cell comes on and shuts right back off. Is it the cell or power center?
A shopper on Aug 4, 2016
BEST ANSWER: I would recommend putting the old one back on to see if it does the same thing. If it does you know it's not the salt cell.
Why are My sanitizer lights are flashing?
A shopper on May 17, 2022
BEST ANSWER: Which lights
How does the chlorine convert back to salt? Where does the sodium come from?
Kelly on Apr 26, 2022
BEST ANSWER: Never heard of chlorine turning into salt
What is a chlorine generator recommendation for 8000 gallon pool?
A shopper on Apr 11, 2022
BEST ANSWER: IC20 will work fine for 8,000 gallon pool
can i replace my ic20 salt cell with a ic40 salt cell without buying the whole system?
A shopper on May 9, 2020
BEST ANSWER: I'm not an expert but I see no reason why you couldn't. The IC40 is is made for a larger pool than the IC20
Can the control panel (face plate) be turned 180 degrees?
Jay F on Mar 29, 2020
BEST ANSWER: No, it cannot rotate. If you look at the first picture on the Pool Supply site, you will see an arrow for direction of flow. The generator must be mounted in this direction.
How do you recalibrate an IC-40? I bought a new one and it reads salt at 1500 PPM compared to 2900 PPM at local pool store.
AC on Mar 9, 2020
BEST ANSWER: I don't under stand, You had a pool place check your pool for salt and they came up with 2900 ppm and you came up with 1500? I would check the date of your chem. I have a 58000 gal.I use two and maintain 2900ppm to 3200 ppm
why is my generator not making chlorine ?
joe o on Aug 2, 2019
BEST ANSWER: Your water may be low on stabilizer, so the chlorine is just evaporating as fast as the generator produces it. The other possibilities are it needs an acid cleaning, or it’s just toast…
High salt reading how to lower?
Tim C on May 15, 2019
BEST ANSWER: I have just dropped the water level in the pool and added more water. That will usually take care of the high salt reading if you just added too much salt.
If the flow light stays red,does that mean it's not working?
A shopper on Mar 11, 2019
BEST ANSWER: Yes. If your pump is not circulating then the system is not generating salt.
