Frequently Asked Questions
What filter cartridge does the Jandy CL340 use?
The Jandy CL340, a cartridge filter system, uses the PJAN85 (also sold as C-7459, all the same physical cartridge). It takes 4 of them. Confirm the quantity in your owner's manual or by counting the cartridges in the housing when you open it up. Some Jandy models in the same series use a different number of cartridges than others.
How often should I replace the cartridge in my Jandy CL340?
85 sq ft is mid-size for a pool filter, which works out to about 12 to 18 months in typical residential use. Hose-rinse between the pleats every two or three months, soak in cleaner once a quarter, and replace the cartridge when cleaning stops bringing pressure back to baseline.
How do I clean the filter cartridge in a Jandy CL340?
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 cartridges. The Jandy CL340 runs 4 cartridges; if any one of them is dirty, the others are too, so pull all of them. 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.
