FILTER OPERATION GENERAL DESCRIPTION
General Operation
Water enters the filter through the "Inlet" (7) and passes through the "Screen" (2), which
purifies the flow by separating smaller particles from the water. The purified water exits
the filter through the "Outlet" (1).
Self-Cleaning Process
As impurities on the "Screen" (2) accumulate, a pressure imbalance is built up between the
internal and external sections of the "Screen" (2).
When the pressures difference between the internal and external sections of the "Screen"
(2) (further - DP) reaches the value preset in the control unit, a series of events are
triggered while the water continues to flow to the user. The flushing valve opens and
pressure is released from the inner side of the "Screen" (2). The "Electric Motor" (6)
simultaneously rotates the "Brushes assembly" (3) around its axis. The "Brush units" (4)
wipe all the dirt accumulated on the inner side of the "Screen" (2) and efficiently clean its
entire surface. The dirt removed them the "Screen" (2) is washed out of the filter to the
drain through the "Flushing outlet" (5).
The flushing cycle takes about 10 seconds. At the end of the flushing cycle, the flushing
valve closes and the operation of the "Electric Motor" (6) is stopped. The filter is now
ready for the next flushing cycle, with clean and filtered water flowing through the "Outlet"
(1).
