How do I clean my cartridge filter?
First turn your pump off and open the air valve! Failure to turn the pump off and open the air valve before unscrewing the lid could result in serious injury. After you have turned the pump off and opened the air valve to relieve pressure, unscrew the hand nut on top of the filter. Lift the filter cover off and lift the cartridge filter out off the filter housing. Be careful, the filter can be heavy. Use correct lifting techniques to avoid injury. Use a pressure nozzle on your water hose (or take the filter to a quarter car wash) to clean the filter inside and out. If you use suntan oil, we recommend using a mild dish detergent to break up the oil (car wash detergent will work also). Return the cartridge to the filter housing, clean the lid, "O" ring and filter housing of debris and put some "Aqualube" or equivalent on the "O" ring. Place the lid on the filter housing, screw the hand nut down firmly, open the air valve, prime your pump (see "How do I prime my pump?") and turn it on. When water squirts out in a steady stream from the air valve, close the valve.
