General FAQ
These saltwater chlorine generator systems come with everything you need except salt, PVC glue, primer, a saw, and a few common tools.
In addition to adding salt to your pool water, installation entails adding one new piece of equipment to your pool. This can be performed by a handyman, plumber, electrician, pool contractor or Do-It-Yourself (DIY).
If you are contemplating installation, read more here.
The simple, industry-wide, rule-of-thumb is that your salt system should be sized at 1.5 times your pool size, or more, for the temperate and colder parts of the US.
If you live in the southern sunbelt, then you should select a system with specs of at least 2 times your pool size.
Bear in mind that an undersized system will be a constant challenge, at best, while an oversized system will extend cell life and give you reserve capacity for weather events and periods of heavy use.

Questions From Customers
Q:
what is the difference between SJ & the RJ systems?
Asked by: Bill
- 3/6/2017
A: Great question. Beside the main differences in power and lifespan, here are a few of the things that set them apart once they are in your hands:
The SJ models are very simple, easy-to-use systems. They have status lights that verify the unit is working, tell you at what power level it is set, and whether you need to clean the cell or add salt to the pool. Because it is simple there is less to think about, it is particularly low maintenance (no acid is required to clean the cell), and it is also less expensive.
The RJ and RJ+ models are the flagship systems. They are more powerful and longer lasting. They have a digital screen and touch keypad, giving you more control and diagnostics. It displays the salinity level in real time, calculates the running average, displays the water temperature, and displays the electronic performance levels of the cell so you can see exactly how things are working. The power levels on the RJ models can be turned up and down in smaller increments. RJ models also synchronize more easily with variable-speed pumps if you plan to upgrade.
So the SJ gives you simplicity and a huge value, and the RJ gives you top of the line performance and control.

I have a small (6000 gallon) fiberglass pool, located in Florida. Is there such a thing as too much when it comes to the size of the chlorinator? For example, will I hurt anything if I choose a SJ-20 versus a SJ-15?

The CircuPool SJ-20 system is controlled by the Control Module. Featuring a convenient medium size, molded-plastic exterior with a touch keypad and LED indicators to monitor settings and performance.
The control module mounts conveniently on most walls, posts, or supports. Just follow the accompanying instructions and mounting template for screw placements and installation.
The digital LED indicators on your control module will communicate whether or not your system is operating at optimum performance levels, and will otherwise alert you with its LED indicators for potential service issues such as: the pool's salt level is low, the cell needs cleaning, there is insufficient water flow, or it the water has reached winter temperatures. Keypad controls will also give you the ability to increase or decrease chlorine output, or activate a boost (or SuperCL) mode.
For the cell component of your CircuPool SJ-20 unit, it comes equipped with an SJ-20 electrolytic cell in a clear, raised housing. This contains a set of titanium electrode plates that can be removed, as well as a built-in power supply cord.
Thanks to its unique design, the SJ-20 has a reduced need for cleaning mineral deposits that may occur, which makes it one of the few systems that do not require acid for cell cleaning. You can easily remove the mineral deposits with the cleaning wand included in your system’s kit!
This cell also features threaded connections near the head of the cell, so you can quickly access the titanium plates whenever you need to service them, or if you need to take them out for winter. The cell comes with both 2” and 1.5” unions to easily connect to existing return-line PVC plumbing. The clear housing on the cell makes it easy to inspect for both cleaning and function purposes!
Included in the CircuPool SJ-20 parts kit is an instruction manual, 2" and 1.5" plumbing unions, o-rings, mounting hardware, flow switch, and cleaning wand.
