Re: Want to add SWG....couple questions
I can't speak to the Aquarite or having a spa, but I can give my take on a couple of your questions:
Installation: Pretty straightforward. I use my AP DIG-220 to control pump run time. The manual tells you everything you need to know. That being said, if you have ANY doubts, consult a qualified electrician. Far better to err on the safe side.
The AP unit is integrated, the cell and flow switch are all in the same header. It uses a bypass valve to send 20-30 gpm (I think) to the cell, while the rest goes to the pool as normal. I believe the advantage to this is that the cell "sees" constant flow to reduce variability in your Cl level.
Since installing the SWC, I've never had CC. I believe you can get the "total control" package which will use ORP sensors to maintain pH and cl levels, but I don't know all the details on these.
I would recomend oversizing the cell. I run the 60 series in my 20,000 gal IG, and maintain 4-6 ppm FC at about 30% in the full summer sun and high bather load. Should lead to longer cell life.
Good luck!
