I measured twice and cut one all the PVC fittings, giving the new fittings a light sanding and coat of PVC primer. I was sure to cut the PVC as squarely as possible, and sanded those tubes so that all paint and oxidation was removed. I dry fitted all the fittings, primed all pieces, and then cemented them all together.
Using the supplies from the Depot, I removed the cover of the control unit and removed the provided power cable. Take a note (or a cell phone camera picture) to remember where each wire gets connected. The white wire to the power switch used a very small connector not available at The Home Depot; I cut wire with that connector, leaving an extra 2", so that I could make a pigtail.
After wiring it all up (I connected to the load connectors on my Intermatic timer), I threw the breaker, crossed my fingers, and it came up like a charm. I will be running the water over to my local pool supply company for analysis this weekend to see how my levels are.
Why do I give it 5 stars despite the short cables? I realize that each installation is unique, so there is no cookie-cutter solution that will fit every need, so why deduct a star if the product itself works as expected. I fully intend to report annually on this unit so that others can get a real-world review, rather than a brief description of my one week of use.
I have to run at 100% concentration nearly all the time to keep my 30,000 in-ground pool at the proper chlorine levels, but it does the job.
Overall I'm very pleased with the SJ Salt Chlorine Generator. I got the -40 with a 22,000 gal pool, so I only have it set to 50% chlorination, in the hope that I can extend the life of the cell and generator system. Long-term reviews on the Circupools on the internet is why I made the purchase; they seem to be very reliable and lower cost than other companies. Time will tell for me, but so far, I'm quite happy with it. I also liked that I could remove the cell without taking out a chunk of the pool loop like some other systems, and the clear housing for the cell is a blessing to visually see the health of the cell and water flow. Excellent work with that!
Installation took a while, but that was more to do with my electrical work than anything else. I had to get a couple 1 1/2 in PVC adapters for the cell housing, but that was not $3 at my local handyman store. Mine arrived without an O-ring for the cell tube, which isn't listed in the parts list, so I had to wait a couple days for one to be shipped to me while my pool was down. It was a quick shipment, and Circupool was very helpful on the phone. It would be good to have a more robust parts list for the instructions, however.
Mounting the controller is done with a provided hole template, where four blind screws anchor the controller in place; If you're not lucky, this can take a long time, as one misaligned screw (from the paper moving, or the drill running off by even a small amount) means having to make four more holes! This method looks elegant when installed, but there are faster, more efficient ways to do this. I'll get to that with the quirks section...
Operation is super straight forward, as it's basically a set it and forget it kind of thing. I have it wired to a GE Z-Wave outdoor appliance switch, which is controlled by Alexa and also manages the pump.
There are a few quirks about the system that made me scratch my head a bit, however. For example, the power cable is terminated with a 1/2" compression fitting for a water-tight fit, but removing it to install a standard outdoor electrical cover is a massive pain, and required me to open the case, which is done with only four screws, and no hinge. This in itself is not difficult, but also revealed some other curiosities. Inside, there is a BEAUTIFUL toroidal transformer and a power regulation PCB mounted to a metal plate for heat, which is connected to the front IO and brains of the system. This case itself is probably twice as big as it needs to be. The bulky ABS plastic looks super 90's, but since it's mostly hidden, it's no big deal. I just can't for the life of me understand why pool companies don't design controllers that match other outdoor electrical boxes? It would cut down on manufacturing costs a lot, make opening for maintenance and repair easier, as well as make mounting faster, as an access door with holes to mark is far more preferable. None of this applies to daily operation, but are still important factors for the design.
Idiosyncrasies aside, I would recommend this to anyone who wants a salt pool, and doesn't need an expensive pool company to do it!
Better than other salt systems that cost twice the price! Installation is very simple and took us about an hour!
