Cleaning the filter elements
•
Turn off the pump
•
Close the main valve A
•
Open vent valve B
•
Open the drain valve D (emptying)
•
Open the clamp ring and remove the cover
•
Close the drain valve D as soon as the filter elements are
standing in water by 1/6 only.
•
Put the cleaning brush over the filter element and move it up and down 6-8 times
and, at the
same time, flush with water from the pump (For this process, water
must not be filtered).
Repeat the process as needed until the surface of the
filter element is clean. In addition to
the dirt particles that will be removed,
some of the ceramic will also be rubbed off in the
process. That is completely
normal and desirable. In that way, you will be assured that the
filter element
has totally new filter characteristics when cleaning is completed.
•
Repeat the above procedure on all filter elements.
