6	Operating principle
1st step	DSX series filter is fitted with a front primary strainer to avoid sucking nozzle blocked. The water flows through the primary strainer from the inlet leaving bigger particles outside the primary strainer cartridge . The the water flows towards the two-stage fine strainer where the small particles are screened and allowing the clean water flowing towards the outlet.
2nd step	The pressure differential will generate once the dirts accumulated on the inwall of fine filter. When the pressure fifference reach to the pre-set value, the controller will send out indicating signal of opening blowoff valve and starting scanner.
3rd step	When the system start blow off dirts, a stream of strong backwash water generated and flow towards atmosphere through blowoff valve. It generats suctions inside sucking nozzle.The sucking nozzle removes the inwall dirts by means of suction and eliminates the dirts through blowoff valve.The scanner keeps rotary and axial moving simultaneously to insure the cleanliness of strainer.
4th step	It'll take 8s~25s for one self-cleaning cycle without interruption of water flow and the loss of water is few. Once self-cleaning process finished, the valve closed and the scanner moved back automatically . The next self-cleaning cycle will start according to the system programming and repeat the above steps.
