When should I clean or replace the filter cartridge elements in my NORSUP CF 230?

[KathrynDella]

To maintain peak performance of your NORSUP CF 230 Cartridge Filter, monitor the pressure gauge. The filter cartridge elements need cleaning or replacement when the pressure gauge indicates a rise of 30 psi (200 kPa) above the starting pressure, or if the water flow noticeably decreases. It's helpful to note the initial pressure reading after installing fresh filter elements to guide your maintenance schedule. If, after cleaning and reinstalling the elements, the starting pressure is more than 25 PSI above the starting pressure with new elements, plan to replace the elements the next time the gauge reaches the red zone. Regular maintenance is crucial for optimal filtration and water clarity in your pool or spa.
