Saltwater Generator and Jandy VS FLOPRO

[Ziadeedee]

Hello,

I know this subject has come up many times, I have searched the forums all over but have never found a definitive and conclusive answer.

I'm going to be adding a saltwater chlorine generator to my inground 10,000G pool this summer. My setup is very basic, I have a 1.65HP Jandy vs florpro pump and I am thinking about purchasing the Hayward Aqua rite salt generator.

After reading multiple forums I realize that redundancies are very important to avoid any explosions. Thus, my plan is to have the VSP on the same breaker as the saltwater generator and to run the VSP 24/7. The second redundancy would be the flow switch included with the salt generator. The problem is, I run my VSP at a reduced RPM for 12 hours and medium speed for the other 12 hours. Will running it at a slow speed add dangerous gases to the system?

Is there a better way to setup these two systems together? Also, on the Hayward Aqua Rite manual is says not to connect it to a timer, yet many people have the same system and have it connected to a timer. Does any one have any suggestions?

I really like the Grid Controls Flow Switches. They are very reliable and there is a model for pretty much any application. Run the power for the salt system through it so, if the flow gets too low or some other issue arises (the SWCG flow switch poops out or the pump quits working), it will shut off.

Ago,

Why do you do this??? What is your goal?

You just need to find the speed that keeps your flow switch on..

Thanks,

You'll have to road test it once installed and possibly bump the low RPM a little to satisfy the flow switch. I have a 3HP pump with simple plumbing and my SWG runs at 700 RPMs.

My skimmers need 1000 and really start working well at 1200 RPMs. That covers the SWG by default. It's so cheap that we splurge a little higher because we like the look of a little more water movement.

I don't suspect your needed RPMs will be a deal breaker.

I run the pump for 12 hours on low just to keep the water moving. It’s cheap enough that I don’t notice a giant spike on my water bill.

Why do you run medium speed ?

Why do you run medium speed ?

Well I’m assuming the pool gets more turnover when I run it at medium speed, thus creating better filtration? I remember my PB told me something along those lines.

 

[Newdude]

I'm sure he did. If the water is moving, it's being filtered. But the PBs never have to pay your electric bill for you, so they just pick an arbitrarily high # of turnovers for you to achieve. If the # is high enough, it doesn't matter how much environmental debris blew in the pool, they were right. But that's only a week or three in the spring. Then you go most the summer needing very little filtration before it increases in the fall again.

Z,

Kind of what I thought... The idea that you have to 'turnover' your pool water x times a day is a myth..

I also run my pump 24/7, because I like to make a little chlorine all the time and skim all the time.. I could care less about 'turnovers'..

I suggest that you find a speed that turns on your SWCG, add 100 rpm, and then run that speed 24/7 and see how that works for you.

In my mind, it makes no sense to run the pump if you are not making chorine.

Edit.. The idea of running 24/7 is so that you do NOT have to rely on the flow switch.. If your slow speed does not turn on the cell, then for 12 hours each day, you are relying only on the flow switch.. Not a great idea..


Thanks,

Jim R.

After long consideration between saltwater generator brands. I decided to go with the circupool RJ. I have a 10k Gallon pool. Would getting the RJ-45 be over kill or cause any issues or should I stick with the RJ-30? Price wise they are very similar.

ooooh, that's a good question. The RJ is excellent, especially the 5% output increments. In Ontario, the RJ-30 will be PLENTY on a 10K pool.

That being said, the 45 will likely give you a longer life and output for the few extra $. The $100 difference, I'd get the 45. You likely will run it at 5-10% during the season if you run your pump 24/7.

Run your CSI negative to keep the plates clean.

Do you use a solar cover? If you do, with the 45, you may need to shut it off for some periods of time.

RJ series lets you adjust SWG in 5% increments.

With a RJ45 5% is 1.2 ppm in 24 hours.

With a RJ30 5% is 0.9 ppm in 24 hours.

Being very oversized can make it a bit more difficult to dial in a stable FC level. You will be adjusting the % around your target.

I do have a solar cover but I only use it at night.
