MAINTENANCE
The Pressure Filter is equipped with the “Backwash” (reversed water flow) system, which quickly cleans the filter without having to open and
disassemble it. The preliminary “Backwash” system operations are as follows:
(1) Switch off the pump.
(2) Open the safety valve, and connect a pipe to the “DIRTY” outlet to carry the wash water of the filter at any time (Fig. 3, Page 3). You can activate
the “Backwash” system while the filter is in operation by turning the knob on top of the filter to the “CLEAN” position. (5) After cleaning the filter,
put the knob back in the “WORK” position.
(3) Put the safety valve back in the closed position.
To clean more thoroughly, you have to remove the various filter materials from the filter and wash them under running water. Do not use
chemical detergents. To open the filter, loosen the lid clips and lift the lid, following the instructions below. After cleaning close the filter,
making sure you position the lid correctly (see Fig. G, Page 4).
