Choosing Best SWG for Hayward OmniPL

[MyBikeIsAwesome]

Encouraged by @JoyfulNoise and @proavia 's suggestions to consider a SWG in a post last month, I've been spending quite a bit of time learning about salt water chlorine generators. I have a few questions that I've not been able to find an answer to yet. Seems the more I learn the more there is to learn At this point I'm more likely than not to make the switch.

My pool was installed with a Hayward OmniPL automation system.

Questions

1. Are only Hayward cells compatible? The OmniPL installation manual pg 63 seems to suggest the warranty is voided if not Hayward.
2. If only Hayward chlorinators are an option, which series is best/lasts-the-longest/most recommended? T-Cell-3, TCell9xx or TCellS3xx. Here's a list I found of compatible models. I'm having a difficult time finding literature that describes how they differ.
3. It seems at least some of these models are only sold in person. I like my pool builder so I could buy it through them, but am open to other options. Any recommended store that sells them?
4. Given a 15k gallon pool in the Phoenix area, is the biggest Hayward cell of 40k about the right size? The step down is 25k and that seems to be less than ideal.

Thanks!

1. A Hayward cell will allow the OmniPL to fully interface with the SWG.
2. One rated for 40k gallons will work well in our desert climate. T15 or similar - they have changed model numbers recently.
3. Be sure it's a genuine Hayward cell. Any local authorized Hayward dealer should be able to help you. Shop around and hit your pool builder up to match the price.
4. Yes - the ones rated for 40k gallons are the ones you need to look at.

I am not sure if there are addition items needed to make the OmniPL work with the cell. Hopefully someone will be along to advise.

You also need a drop based salt test. The full Taylor salt test kit is the K-1766 - but I think you can just order the 2 needed reagents and add them to your TF-Pro
You will want to test your pool water first, before adding any salt. Then only add enough to get to the low end of the SWG operating range.

Here is a relatively recent post on the forum about adding a SWG to the OmniPL

Adding SWG With Hayward OmniPL

I'm new to the forum, and fairly new to pools. We had our pool installed last year, and I'm exploring the idea of adding a SWG. I have Hayward OmniLogic PL automation, and I have 2 bodies of water (pool and hot tub) on a single set of equipment, the automation toggles them back and forth (not...
