The flow switch will work great on the horizontal pipe after the filter. It shouldn't be mounted with down flow or gravity may close the switch when it fails.

Direction of the cell with an external flow switch doesn't matter. That can be mounted downward.

No only pool return.

Okay that makes sense. I was concerned with the short space under the cell and above. I'm so excited to get a working system. I have been fighting this set up since the pool was installed. 1.5 years ago. I had a salt intex pool for 8 years with no issues. So when we bought a new house. We wanted some thing more permanent. So our budget allowed for this semi inground. And the salt system has been a thorn in my side. Will update when it arrives tomorrow and get it installed.

After studying the pictures I now understand what you meant in picture one.
Please ask us to rewind or slow down *anytime* we get too far ahead for you. It takes a min to grasp it all. :)

Put the flow switch more towards the right side of the horizontal pipe. You have a simple system with oodles of flow, but it might be a little turbulent immediately out of the filter which could theoretically mess with the flow switch. Leave a little pipe after the flow switch so you can easily splice in another one when it fails one day without needing a new 90 and cell union.

Then the cell goes more or less where it is, but lower it a little for the same future splice / coupler reason.

Good point! That might be the reason my aqua troll had issues with no flow light coming on. And it didn't require a flow switch.

With the turbulence. Is it better to run my pool on high or low?
 
Update! Got the new system. Circupool RJ45+. The cell was a easy slip in from
the hayward. I did have to add the flow switch using the adapters that came with it. Got the controller wired up. See picture of new set up.

According to the formula in the circupool manual it shows for oval pool
15 x 26 x 4.5 x 6.7 = 11,758.50. So my RJ45+ is 3.75 times more than my gallons so should work great at a shorter time running and lower salt production. I will update my profile.

I got it wired up. Just had to undo the hayward and wire up same place.

I got it running but have a questions. It's reading power, flow, temp, voltage, software version and cell type.


But it's showing cell amps as zero. And salinity now as 0000.

The salinity button show salt 2400. My digital salt tester it shows 2700.
I had the water tested yesterday at pinch a penny and it tested 3400. (Still thinking of getting the TF professional salt kit) added a 1/4 bag of salt just to see if tomorrow it shows higher salt.

Just wondering what up with the cell amps and salinity now reading all 0's?
Going to let it run all night and check in the morning.

I googled and found answer to my questions. The cell amps at 0.00 means not generating chlorine.

Salinity 0000 means salt to low to measure.
Will see what readings are in the morning. As I added a little salt tonight and pool is running.

When your Hayward warranty replacement comes sell the system and recoup some of your $. Ebay is a great option. Glad your install went smoothly!

Yes, I plan to do that. I'm happy it went smoothly as well. I'm a do-it-herselfer but I'm afraid of electricity. So made sure I turned off the main first.
 
Update: DSP customer service is awesome!

I emailed them and sent pictures of what my system was showing on the cell volts and showing 0.00 amps and not showing salinity now. They got right back to me and said it sounds like my hook up is 110. So told me to change the jumper and add the second one as shown in the manual. I did that and now getting all readings.

And it's nice to see the cell pushing out tiny bubbles. My intex swg was clear. My hayward was not. I had to take it off and put in bucket of pool water to see if it was working.

On to making chlorine now. Woo hoo!
