Designed for Outdoor Installation and Operation
The CircuPool SJ-35 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-35 unit, it comes equipped with an SJ-35 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-35 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!
