Installation and Operation Manual
Jandy® Cartridge Pool Filters
CL and CV Versa-Plumb™ Series Filters
Cartridge filters do not require sand or diatomaceous earth as the filter medium. Instead, the filter contains filter elements which are easily removed for cleaning or replacement. Dirty water flows into the filter tank through the water line connected to the lower bulkhead (inlet) on the bottom half of the tank body. It is directed through the filter cartridge inside of the filter. The debris is collected in the filter and the clean water flows out of the filter through the upper bulkhead (outlet) on the bottom half of the tank body. Clean water is returned through the piping system to the pool. As debris collects in the filter, the pressure will rise and water flow to the pool will diminish. The filter will eventually become so plugged with debris that it will be necessary to remove the filter cartridges and clean them with soap and water.

Dirty water flows into a two or three port diverter valve, then into the filter through the lower bulkhead on the bottom of the tank and is directed through the DE grids. The debris is collected on the surface of the grids as the water flows through them. The clean water is directed into the manifold, then through the outlet tube, and finally, out of the filter through the upper bulkhead on the bottom half of the tank. The filtered water then goes through the two or three port diverter valve and is returned through the piping system to the pool. As debris collects in the filter, the pressure will rise and water flow to the pool will diminish. The filter will eventually become so plugged with debris that it will be necessary to perform the backwash procedure. It is important to know when to backwash the filter. See Section 6 for further discussion of backwashing the filter.
