4 Function
The untreated water flows through the untreated
water inlet into the filter and there from the inside
through the filter element to the clean water outlet.
Impurities >90 µm are trapped on the inside of the
filter cloth. Depending on their weight and size,
these particles fall directly into the lower section of
the filter element or the filter cloth. The filter element
can be cleaned by backwashing at regular intervals.
Backwashing is carried out manually according to
the effective principle of backwashing by suction
(suction-backwash system). The filtration process
continues uninterruptedly even during backwashing,
as approx. 90% of the filter surface is constantly
available for filtering (nonstop filtration).
5 Installation conditions
Observe local installation regulations, general
guidelines and technical data.
There must be a flush of at least 3.5 m
3
per hour for
backwashing, or a pressure of at least 2 bar during
backwashing behind the filter.
A connection to the sewage system (drainage) of
min. DN 50 must be available.
The installation site must be protected against frost
and must guarantee the protection of the filter from
solvent vapours, fuel oil, lees, chemicals of all types,
UV radiation and heat sources over 40 ºC.
Keep plastic parts free from oil and grease, solvents
and acids as well as basic cleaners. After hard
collisions and impacts (e.g. with unsuitable tools,
falls onto stone floor, etc.) a plastic part must be
replaced, even if there is no visible damage (danger
of bursting). Avoid extreme pressure blows.
