Is the warranty on the Intellichlor IC 40 for two years?
kmw58 on Dec 21, 2015
BEST ANSWER: That is correct. They were just upgraded to 2 year warranty earlier this year. So moving forward from that point, they have a 2 year warranty.
What is the delivery time to Georgia on the ic40?
A shopper on May 3, 2017
the lights on my salt generator stopped working. what does that mean?
A shopper on Apr 5, 2016
BEST ANSWER: It needs to be cleaned at least every time the pump is cleaned. Usually 4 times a year. We had the same thing and cleaning fixed it.
If my pool is less then 20,000 do I need the Intellichlor IC-40 or is the IC20 sufficient?
Phil O on Sep 5, 2015
BEST ANSWER: With a chlorine generator it is best to be over sized so you will be able to meet high demand and in normal operation your cell will not have to work so hard. A good rule of thumb is to double what you have so with a 20,000 gallon pool the IC40 is perfect.
what size Intellichlor do I need for a 33,000 gal pool?
A shopper on Mar 21, 2016
BEST ANSWER: For your size pool, I would use a minimum of the IC40. If your budget allows it, upgrade to the IC60. It's a little more expensive off the bat, but since it's oversized it will last much longer saving replacement costs in the long run.
Does the cell shut down when the water is cold?. All the lights go out except the cold water light.
Warren T on Feb 5, 2016
BEST ANSWER: Yes, it's a freeze protection. At a certain temperature the unit will not operate properly so it shuts off automatically.
My pool technician just tells me my Intellichlor system needs to be replaced. It has been very cold at night but warms during the day so it may be adjusting itself when needed. They say the salt levels are 4000 and have been adding salt tabs bc cell isn't working. Also, want to charge me $900.00. Any advice? Not happy.
Robin S on Feb 8, 2016
BEST ANSWER: I'm not sure about your specific situation, but with no experience, I was able to change out my intelliclor. All I did was buy an over sized pair of channel lock pliers( big enough to fit over the ridges of the black connectors, stop the pump, disconnect the power supply, remove the old one and reverse the order to install the replacement. The hardest part is remembering which direction to turn the connectors- Righty tighty, Lefty Loosey. I think my 8 year old would do it for less than 900.00. If that's truly the cause, it could be fixed for the cost of the part and a tool. Mine works fine.
two questions: 1-can an chlorine generator be used on a non=salt water in ground pool? is instillation possible by a home owner & where in the system is it installed
Gregory W on Oct 12, 2015
BEST ANSWER: It cannot be installed without switching the whole system to salt water. The chlorine generator works by breaking down salt, which is chemically NaCl, sodium and chlorine, into it's components. It needs the salt to create the chlorine.
My unit flashes red and then green to high salt then the red goes on (low salt) then the red light stays on constant. the salt is 3200 the generator recommends 3400 will this make the alarm light go on if it is below 3400?
Hal E on May 24, 2016
BEST ANSWER: Yes the salt must be above the 3400ppm
I have a40k pool should i get the ich60?
A shopper on Mar 26, 2016
BEST ANSWER: I researched this question myself. I was told that getting one that matches your pool size is good but getting one with a higher level of power works better and it worth it if it's only a couple of hundreds more. It's worth the investment. The amount of power is lowered. My two cents.
Salt level flashes between green and red. Flow light is on all the time. What do I need to do?
Sue on Jun 14, 2019
BEST ANSWER: Nothing it’s calculating your salt level give it a minute or two it will stop eventually you should be okay just be patient
do I need to replace power pack when replacing the IC 40 salt cell?
Roger on Aug 14, 2016
BEST ANSWER: I replaced the cell and simply connected to the existing power pack. Worked fine.
will this unit still produce chlorine when flashing green light indicates high salt? Salt is 3500 ppm tested at pool store
fraze on Jun 14, 2016
BEST ANSWER: It will continue to produce chlorine as usual even if the salt is currently too high. Continue to monitor and don't add salt until the lights blink yellow, then have it tested again at your local pool store so you know how much salt is needed.
My intellechlor C40 flow light is red indicating the unit is turned off. How do I turn it on?
Kenett A on Jun 1, 2018
BEST ANSWER: Which light? You I’ll only get red lights if you need to add more salt to the water, if the water is too cold to produce chlorine, or if there is not enough flow of water ( this means something is blocking the water flow inside the chlorinator)
Would I go with IC 40 or IC 60 if my pool contains around 42,000 gallons??
Granick on Jun 25, 2016
BEST ANSWER: My pool is 16 X 36 with 9' deep end and holds about 26,000 gallons of water. I bought the IC40 because of the amount of direct sunlight my pool gets and have been pleased. I would consider how much shade your pool has. If it gets a lot of direct sunlight, I would go with the IC60 to be safe. If it has a lot of shade, I think you would be OK with the IC40. Hope this helps.
The face of my new system is upside down will it still work?
Lisa M on May 15, 2017
BEST ANSWER: Yes. Mine also is upside down. You have to have the flow direction towards the flow valve (that movable disk-shaped regulator at the top). It all depends on how your piping was plumbed.
Red light on, system off?
A shopper on Mar 7, 2017
BEST ANSWER: It can mean a number of things: water is too cold to produce chlorine, low salt in the pool, system not functioning (cell may be bad), cell may need cleaning.
I have a 15500 gl pool. Should I have an IC 20 or 40?
Rey G on Jul 3, 2020
The man came to open my pool for the summer. He added a bag of salt . My intellichlor generator red light after 2 days is still on and I then pushed the 2 boost buttons and now all of the green lights keep lighting up from min to max in a row. I thought that was to stop after 2 min --what should I do?
A shopper on May 24, 2020
BEST ANSWER: The LEDs stay on all the time, check your salt level it should be at least 32000 or above you also need to check the generator to make surest clean
Does the ic40 include power/control cord for easy touch controller?
A shopper on Oct 14, 2019
BEST ANSWER: The ic40 comes with a cord
what is the best way to clean the system? Please, the procedures to use
jackz on May 1, 2018
BEST ANSWER: Remove the cell from the pipes, cover one end with a plastic grocery bag and screw one of the extra end washers over the bag to seal the end. Stand the unit up outside, put on some acid gloves and eye protection and fill the unit with Muriatic acid from the hardware store. It will bubble and smoke and then stop. After 10 minutes dump in a harmless place and soak/rinse everything with copious amounts of fresh water from the hose. All the deposits on the plates inside should be gone. Replace the cell on the pipes
Is there a way to adjust the system to increase chlorine output? Had my water tested and they said everything was good, except it had almost no chlorine and I should bump it up to 100% for a little while. All the lights on the system are green, but I don't see anything on the system regarding chlorine output.
Phil N on May 19, 2017
BEST ANSWER: Just pump it up to 100% 4 day then check your chlorine levels they should go up then you can find what percentage keeps it on an average depending on the sunlight
Do you open the salt cell up to clean inside of it ???
cindy E on Apr 22, 2017
BEST ANSWER: No, but it should be removed once or twice a season and cleaned inside with a solution of muriatic acid poured into it standing on end in a bucket (other end plugged). When it stops foaming crystal build-up should be gone & rinse well.
is this item new?
A shopper on Sep 22, 2016
BEST ANSWER: This is a replacement part. The original was > 5 years old. Which I understand is the "life". I ordered due to the savings VS my local pool supply store and am very satisfied. Thanks.
How do you clean the IC40 cell?
A shopper on Aug 2, 2016
BEST ANSWER: An easy DIY task. You can find the instruction manual and a FAQ on this subject at the Pentair website. Simply Google Pentair Intellichlor.
Is basically a case of removing the cell from the plumbing (two easy to remove connections) then flushing out with diluted acid. Be careful with acid and follow directions. To make it easier you can also purchase a kit which provides a cap to put on one end of the cell while cleaning. I have one and it makes task much easier. Good Luck.
The cell light is on solid yellow. Just clean or replace?
Rob A on Jul 16, 2016
BEST ANSWER: Cleaning the cell is always good, make sure to turn all power off to cell, unplug the cord from the transformer, clean the cell thoroughly, plug the cell back in to the transformer, restore power, good luck
What version is this item (version 1.9 or 3.7, etc)?
A shopper on Jun 23, 2016
BEST ANSWER: Not aware of any version#
I have a 5plus year old Intellichlor chlorine generator IC40. A couple days after I did the acid cleaning of the cells It started spraying water out the side where the plastic top cover slides back and forth. Can this be repaired or is it time for a new one?
Ray G on May 22, 2016
BEST ANSWER: The cells generally last about 5 years anyways. I had mine about that same time and it's output greatly dimished. I would just replace it at this point.
How do I clean the Intellichlor IC-40 myself?
Terry W on Feb 20, 2016
BEST ANSWER: Piece of caje. Screw on an end cap to close one ebd. Then pour in a 50/50 mix of muratic acid diluted with water. Let it sit for 15 min. The salt on the blades will disolve and just pour out the diluted acid.
Replaced my IC20 with and IC40. Control panel is upside down when mounted for correct flow. Do I just have to live with this?
A shopper on May 4, 2020
BEST ANSWER: I did not have that issue but if it works good I would live with it:)

Two Failures in Two months, third unit working poorly
When my Previous cell got the "Clean" alarm which would not reset I purchased a new cell. I did notice that the design of the cell was new with plastic dividers in-front of the cells. When installed the cell seemed to work fine for a month before it completely failed , tripping the breaker on my Easytouch. Pentair replaced the cell under warranty and 6 weeks later the next cell failed . Pentair sent out a company to check my system and they verified that it was another bad cell and they replaced it again.. That was 6 weeks ago and things are still "Working" . I have an intelichem system and this new cell seems to have trouble generating enough chlorine . Starting from a chemically balanced pool It has fell behnd in ORP and been on all day for the last 6 weeks . I'll give it a few more weeks then call it in. Something seems to have changed in these cells . They are very unstable. I am considering going with another salt system if this fails again.

Great unit but has a few glitches
The Pentair Salt Generator is a real time saver and may even save $$ versus treating your pool with chemicals. It's kept our pool clear all summer and is a huge time saver - we couldn't live without it.

My only concern is the lights on the control panel either shut off at times or give misreading signals that the pool is low or high on salt concentrations for instance. We also had issues with the low or high salt readings on the last one we used.

Still, I would highly recommend this unit.
August 22, 2016
My original required cleaning too often, so after 5 years, I decided to replace the cell. The replacement cell from Pool Supply was fairly price, came quickly and was simple of install. It's producing abundant chlorine from the salt water, and the frequency of cleaning requirements has returned to normal.
