The cleaning sequence

The control system activates the self cleaning sequence at a preset pressure differential level or by a preset timer,
whichever comes first

(Fig8)

The cleaning sequence starts with the control unit starting the flushing pump

(Fig9)

, which boosts into the system highly

pressurized clean water. The inlet and outlet valves are than closed isolating the filter from the main line. A few seconds
later, the drain valve opens, emptying the filter

(Fig10)

Figure 8

Figure 9

Figure 10

The highly pressurized water enters the filter through the flushing control valve, into a shuttle pipe fitted with a movable
spray unit

(Fig11)

. The spray unit

(Fig12)

moves back & forth along the entire length of one cartridge row, pushed by a piston

driven in both directions by boosted water
