Use
The filters are intended to filter drinking and do-
mestic water. They protect the water pipes and any
connected system parts for transporting water from
malfunctions and corrosion damage due to such as
rust particles, chippings, sand, hemp, etc., up to a
diameter of 2 mm.
The filters are not intended for use with chemically
treated circulating water. Expert advice should be
sought if to use to filter process water and cooling
water for continuous cooling systems.
A coarse sediment bowl should be added for water
containing coarse sediment particles.
The filters are not suitable for oils, greases, sol-
vents, detergents and other lubrifying media, nor
for separating water-soluble substances.
The installation of the equipment and significant
modifications may only be carried out by the water
supply company or an installation company.
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 filtra-
tion process continues uninterruptedly even during
backwashing, as approx. 90% of the filter surface is
constantly available for filtering (nonstop filtration).

Installation conditions

Observe local installation regulations, general
guidelines and technical data.
There must be a flush of at least 3.5 m
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.
