The Compupool Salt Chlorine Generator is a high-performance salt water chlorination system that lets you enjoy perfectly clear pool water without the use of harsh chemicals. It is a safe, clean, easy alternative to dosing your pool with dangerous and expensive chemicals. The Compupool Salt Chlorine Generator is setup and automatically controlled by its Compupool Control Unit. This guide shows you how to operate and read the touch pad controls and LED lights on the Compupool Control Unit.

Tips & Warnings

Step by Step

Step 1
CompuPool Salt Generator

ON/OFF – This button turns power to the Control Unit on and off. In an OFF state, all LEDs are off and the display will show the current time and POWER OFF. To turn the Control Unit ON, press the button once. The POWER ON LED and one of the POLARITY 1 or 2 LEDs will illuminate and the display will show time and the % of current Chlorine Output setting. Note that this button only turns on power to the Control Unit. The SET TIMER and OUTPUT functions (described next) may have to be set to pass power to the Cell and generate chlorine.

Step 2
CompuPool Chlorine Generator

SET TIMER – The Control Unit has the option of working off an external timer or off of two internal timers. This function allows you to set two internal timers to generate two chlorination cycles per day. To enter the timer mode, press the SELECT button and hold it for 3 seconds. The Display screen will ask WHAT LANGUAGE? Select a language with the up and down arrows. Then press SELECT again. The Display will now show WHICH TIMER? EXTERNAL. If you want to bypass the internal timers, press SELECT to go to the next setting (SET CLOCK). If you want to set the internal timers, press the down arrow to change the setting to INTERNAL. Pressing the SELECT button again will display ON TIME 1. Select the start time hours for Timer 1 with the up/down arrows. To change AM to PM, you have to keep scrolling through the hours until you get to the AM or PM setting you need. To set the minutes, use the right OUTPUT arrow to move the cursor from under the hours to under the minutes and then change minutes with the up/down arrows. Press the SELECT button to display OFF TIME 1 – set the end time for Timer 1. Set TIME 2 using the same process as above. Then press SELECT once more to SET CLOCK. A final push on SELECT will exit and return your Display to normal operation mode.

Step 3
CompuPool Salt Generator

SET CHLORINE OUTPUT LEVEL –The Chlorine production level can be set from 0% to 100 % in increments of 10%. To set the production level, press the OUTPUT arrows left or right. The % Output level will be shown in the Display. Note, at a Output level of 0% the Cell is turned off and the display will read OUTPUT OFF.

Step 4
Compupool

SUPERCHLOR - There are occasions when you will need higher than normal amounts of chlorine to be generated - when you have an abnormally high swimmer load, after a heavy rain, or if you have a cloudy water condition. To increase the level of chlorination, simply press the SUPERCHLOR button. This electronically "super chlorinates" the water by increasing output to 100% for a cumulative 24 hours. If, for example, your pump runs 8 hours a day, the Cell will remain in SUPERCHLOR mode for three days before returning to normal operation. Or, if you elect to stop SUPERCHLOR at any time, you can simply push the SUPERCHLOR button again to return to normal operation.

Step 5
Compupool owners manual

WINTER MODE - If you are not using your pool during the winter months, we recommend that you put the chlorinator in WINTER MODE by pressing the WINTER MODE botton. This reduces the output of chlorine by 50% of your current output setting. For example, if your output is set at 80%, pressing the WINTER MODE button will reduce the output to 40%. To return to normal operation in the spring, push the WINTER MODE button again.

Step 6
install compupool

MANUAL OVERRIDE - If the Control Unit is operating between the two internal timers (between OFF TIME 1 and ON TIME 2), it's in IDLE mode and the Cell in OFF. To manually override this function, press the SUPERCHLOR button. The cell will come on in SUPERCHLOR mode.

Step 7
compupool

POWER LED - When this LED is illuminated, the Compupool Control Unit has input power. This only indicates that the Control Unit has power. The timer has to be on and the output level must be greater that 0% for the cell to be active and generating chlorine.

Step 8
CPSC24

POLARITY 1 or 2 LEDs - When either is illuminated, it shows which end of the cell is producing chlorine.

Step 9
Compupool salt generator

WATER FAULT LED - When illuminated, the flow switch has detected that no water is flowing and the cell has stopped generating chlorine. The Display will read NO WATER. Check pump operation.

Step 10

ADD SALT LED - When illuminated, the salt level is too low and the cell is generating at low efficiency. Additional salt should be added. See our guide on "How To Add Salt To Your Pool".

Step 11
CPSC24

OVER SALT LED - When illuminated, indicates that the salt level is too high. To get the salt level back to acceptable levels and turn off this LED, purge some water out the WASTE line of your filter and add fresh water to the pool. See our guide on "How To Reduce the Salt Level In Your Pool". If you do not bring the salt level to within the acceptable, the cell will draw more current, run hotter, and fail.sooner than normal.

Joe - I just talked to the Compupool Rep and, unfortunately, he said your problem is due to a bad Display PCB which will have to be replaced. Here's the link to that board - Display PCB.

User: Joe

My display on my CPSC24 is stuck on compupool ultrakleen and it won't let me do anything. Does anyone have any ideas?

User: Inyopools

amazinghouse - We would need your specific pool test results to help isolate this problem. A couple of possibilities are a CYA imbalance or a very high phosphate level.

User: amazinghouse

I have a 15000 cu ft pool located in South Florida and have been using a CPSC24 unit with relatively no problems. Recently my pool has been turning green - darker and darker with no obvious explanation. The unit is reading okay with everything: flow, salt level, etc.) I've had the pool water tested by several different pool stores and the results are the same: Plenty of chlorine, plenty of salt, all other items within normal parameters. I've tried adding algae remover, additional chlorine, etc. Nothing seems to work. My pool is now dark green and no one seems to know what to do. Does anyone have any suggestions? Thanks

User: 

Can an external flow switch be used to control the on/off feature of this cell.

User: Inyopools

Annel - If all your LED lights are on, this is usually an indication that you have 110V power coming into the unit and the unit is configured for 220V. Verify that your supply voltage is 110V and convert the unit's wiring from 220V to 110V. If this is not the solution to your problem, see our guide on "How To Isolate and Correct Compupool CPSC Problems" for further information.

User: Annel

my system is freeze and the lights are all on, how I doing to.

User: Inyopools

Rals - Yes, increasing the speed of your VS pump may solve your problem. Chlorine Salt Generators generally have to have a minimum GPM flow to operate. Also, it wasn't clear if you just added salt. If the salt isn't completely dissolved, the water fault light will go on

User: Rals

The water fault led is on. I changed the pool filter and using your on line directions cleaned the unit plates. Turned everything on and everything appeared to work. The test showed that salt was at 2500ppm and the add salt LED went on. Unit was generating Cl but after 5 min the water fault LED came on again and unit stopped generating CL. I do have a variable speed motor. Will increasing speed help?

User: Inyopools

Norm - [Response to first question om 8/12] I just check with Compupool. They confirmed that you will need an external timer to coordinate the operation of the CPSC salt generator with the pump. The CPSC cannot control the pump and it cannot operate without the pump being on. Typically the pump and the CPSC unit are wired together on the output terminals of the external timer so that they both go on and off together. If you ran the pump continuously, you could selectively run the CPSC in two different shorter cycles within the 24 hour day using the two internal timers. But most people would not want to run their pumps more than 6-10 hours a day.

User: Norm

I have a variable speed pump that has a built in timer. The pool service company wants to install an external timer for the Compu pool unit. When I followed the directions for setting the timer nothing happens. It does not give an option for timers. My pool service company says it won't work with a variable speed pump. Shouldn't the Compupool unit at least show me the option to use the internal timer?

User: 

Norm - The CPSC series has two internal timer functions to allow two filtration cycles per day. However, they generally do not have the capability to turn the pump on and off. You will need an external timer to control the pump.

User: Norm

I have a Compu Pool unit. I have had it for two years. Today my pool service company (that owns the unit)told me I need to have a separate external timer for the Compu Pool unit. I thought it had an internal timer.

User: Inyopools

novaman - The SCG has to go in after the heater and as the last unit in the return line. See our guide on "How To Install an In-Line Salt Chlorine Generator". It has your same setup with a heater. The SCG replaces the old Chlorinator and is cut into the discharge pipe of the heater.

User: novaman

I just pursched a comp u pool cpsc 24 for my in ground pool.How do I install it with a heater ?? Not sure with lines to use.
Thanks ):

User: Inyopools

Alarnalilly - Over time the power sockets in the cord head may corrode and melt and start to push away from the cell. See our guide on "How To Clean a Corroded Salt Chlorine Generator Cord Head" for information on correcting this situation.

User: Atarnalilly

After calling in to correct the Non-Gen error (codes did not work) so I removed the power cap and found the two outlying connectors have melted. What could have caused this and is it covered by warranty? If so what should I do?

User: Inyopools

confused - Most people run their SCG as long as the pump is running so the SCG is generally run off the pump timer- generally for 8-10 hours. The % chlorine setting varies according to the season, use of the pool and size of the pool. If you are running the pool during the winter, you will set the % lower that when you run in the hotter summer. Larger pools require more chlorine so can run at a higher % than smaller pools. If the pool has heavy use, you generally put the % higher. I would set the SCG % at 50% for a couple of days and see if that is generating enough chlorine for your pool, then adjust as required. Make sure your pool chemistry is correct. If your SCG reads temperature, it will be actual water temperature. If your SCG is reading 4400 ppm and the store test shows 2900, your SCG may need to be recalibrated. Give your manufacturer a call for re-calibration instructions.

User: confused

I am in the dark about how long the timer should be set. Where does it say how long session one or two should be. How far apart should they be set? What is the normal setting for % of chlorine? Is the temperature reading a setting or should it be reading the actual water temperature?
The salt level as tested at the store and the machine are both different. Which do I follow? The store test 2900 and my machine says 4400. Please help.
Thanks

User: john italy

Thanks for your comments; as I use skype for my phone and skype cannot access an 800 number, grateful if you would provide the full USA telephone number to call from overseas.

I have tried to contact Compu Pool Australia, but the responsible person there is not very helpful/knowledgeable and is very slow in responding.

Thanks again.

User: Inyopools

John, Italy - There are several possibilities for a "Water Fault" indicator: 1- Check your salt level. It has to be above 2500 ppm. 2- Check water flow. Are slimmer and pump baskets clogged?. 3- Tighten cable connection by gently crimping the female end of the cable at the cell. If you still have a problem, give Compupool a call at 1-800-989-7258 x225.

User: Inyopools

dalila1004 - You may have a defective unit. If you have a Compupool Salt Chlorine Generator, give Compupool at call at 1-888-989-7258 x225. They should be able to help you.

User: John, Italy

I have a CPSC36 model. Water is flowing through the cell as normal but the red warning light for "Water fault" comes on (step 9 above)and no chlorine is generated. Can anyone inform me what is the problem?

User: dalila1004

I am a little concern that the cell that came with the brand new unit I bought a year and 5 months ago has corrosion and when the cell was taken out to clean I also notice that it has eroted away from plate. Also notice that only the Polarity 1 light is lit and polarity 2 never lights up.Can you directed me to the correct area as to see how I can resolve this problem.

User: larry

I have the CPSC36 CompuPool salt generator and was getting the "non-genuine call dealer" message. I have seen posts directing you to call them which I was going to do. But I removed the 3 prong circular plug that plugs directly into the salt cell and noticed that some hardened plastic was in one of the female holes. Apparently a small portion of rubber insallation around one of the 3 holes had melted. I scraped it out with a nail and needled nose plyers, plugged it back in and still had the message. I then turned the unit off then back on and it is now operating correctly. I will call them and ask about the melted plug(normal??) and take it from there. At least it is now working again.

User: Inyopools

marioland79 - Try crimping (slightly) the female connections on the cell plug to create a tighter fit around the connection terminals. See our How To Guide on Cleaning a Corroded Salt Chlorine Generator Cord Head. If that doesn't correct the polarity issue, call Compupool at 888 989-7258 x401

User: marioland79

On my cpsc16 only one polarity works, after i recalibrated it. if i last calibrate polarity 1, then always polarity 1 is on. if last calibrate polarity 2, then always polarity 2.thank you.

User: Inyopools

marioland79 - Please call the manufacturer, Compupool, at 888 989-7258. They can help you recalibrate your system.

User: marioland79

Hello, i have a cpsc 16, i tried to recalibrate it but the values is +24 instead of 16+. shall i change it?

User: Inyopools

Shawn - If any electrode plate is broken away from its bracket, the cell will have to be replaced.

User: Shawn

I was getting the no flow light. Front of Cell was corroded. Cleaned per directions. When corrosion was gone, I could see two tabs were eroded away from the plate. Is the cell usable/junk?

User: Inyopools

biasd01 - Please call the manufacturer, Compupool, on this question at 888 989-7258. They will have the answer to this question.

User: biasd01

I'm geting an "idle" indication on the display. Is this normal or do I have a problem?

User: Inyopools

Gweedofirehawk - Some SCG manufacturers have found that there were too many factors involved to generate an accurate salt level reading. They elected instead to flag a 'too high' or 'too low' condition and recommend getting an accurate reading from your pool store.

User: Gweedofirehawk

Why doesn't the unit tell you what the salt level is in the pool?

User: 

Susie - You should set the external timer to go on 5 minutes after the pump starts and to turn off 5 minutes before the pump goes off. You can get into the menu by holding down the select button.

User: Inyopools

Susie Medic - I'm not sure how you have this wired. If it is wired so that the Chlorine Generator stays on when your pump goes off, a red "no water" light is what I'd expect. Just means that the Generator has shut down because you have no water flow. Should not be an issue as long as the light goes off when the pump goes back on.

User: Susie Medic

My "no water" red fault light is on. I am using an external timer. When the pump is not running is it normal for the red "no water" light to be on or is this a sign of something seriously wrong?

User: InyoPools

bewildered - Try slightly crimping the female leads on the power cord to your cell for a tighter connection. If that doesn't work, give Compupool a call. They will be glad to help you. Their number is (888) 989-7258.
