Frequently Asked Questions
What filter cartridge does the Hayward Super-Star-Clear C4020 use?
The Hayward Super-Star-Clear C4020, a cartridge filter system, uses the PA100N (also sold as C-7487, all the same physical cartridge). Confirm the quantity in your owner's manual or by counting the cartridges in the housing when you open it up. Some Hayward models in the same series use a different number of cartridges than others.
How often should I replace the cartridge in my Hayward Super-Star-Clear C4020?
At 100 sq ft the cartridge in a Hayward Super-Star-Clear C4020 has a good amount of media to work with, so 18 months to two years is a fair expectation with balanced water. Go by pressure, not the calendar: when the gauge sits 8 to 10 psi over the clean starting point and a soak won't drop it, put in a fresh cartridge.
How do I clean the filter cartridge in a Hayward Super-Star-Clear C4020?
Turn the pump off and bleed the pressure from the filter tank (open the air relief valve at the top). Then open the housing and pull the cartridge. Hose them down at a 45-degree angle between the pleats, working top to bottom. For a deeper clean every few months, soak in a pool filter cleaner solution per the product's dwell instructions, then rinse before reinstalling. Don't use a pressure washer. The high pressure tears pleats permanently.
