Common buying mistakes
Frequently asked questions
How should a CircuPool system be sized?
Choose from chlorine output and realistic peak demand, not maximum pool gallons alone. Oversizing provides operating reserve.
What is the difference between the RJ and SJ series?
RJ models generally offer more advanced controls and output options, while SJ models emphasize simpler operation.
Can CircuPool systems use 1.5-inch and 2-inch plumbing?
Selected Universal models include unions for both sizes, but every installation must be checked by model.
Why does a salt system stop producing chlorine?
Low flow, low or high salt, cold water, scale, wiring faults or controller errors can interrupt production.
How often should the cell be cleaned?
Inspect it at the manual's interval and clean only when scale is present using the approved method.
Does the generator replace water testing?
No. Free chlorine, pH, salinity, stabilizer and supporting water-balance parameters still require testing.
Can the system run at low pump speed?
Only when flow remains above the cell's required minimum and the flow switch stays satisfied.
Are CircuPool cells interchangeable across series?
No. Match the exact controller, series, connector and rated output.
