Instructions for ass mbly, us and maint nanc .
1. Possibl applications
The range of water filters CINTROPUR® NW 8 -25 -32 is designed for filtering clear water with only
low levels of substances in suspension, of the types town water, rainwater, borehole water, spring
water.
Other types of non-aggressive liquid can also be filtered. The possible areas of use will be in
domestic, industrial, public and agricultural situations.
The materials used for making the filter are suitable for filtering liquid foods. The use of the 25 TE-
CTN + NW32 TE + DUO-CTN + TIO with activated carbon is well known for de-chlorination, removal
of odours, improvement of taste, reduction of pesticides and herbicides.
2. T chnical d scription
Installation and use of the filters NW 8 - 25 - 32 - 25 TE (-CTN) - 32 TE - DUO (-CTN) - TIO must
comply with the technical requirements stated in the following table:

3. Ass mbly and handling
•The filters must be fitted using the correct procedures, by qualified personnel: they must be
free of mechanical stress, with the piping upstream and downstream aligned. The distance
between the couplings must be correct to avoid causing any tension or compression stress
on them.
•The ideal location for the CINTROPUR® water filter is directly at the plant inlet (after the
meter or the pump). Ensure that the direction of water flow corresponds to the direction of
the arrow on the filter head.
•The pressure reducer will effectively reduce the supply pressure if it exceeds the operating
pressure. An anti-water-hammer device is essential if they are known to occur in the
installation.
•The filter is supplied complete and ready to install. The equipment supplied includes a set of
2 threaded connectors (except with the DUO where there are 2 connectors of size ¾’’ and 2
connectors of size "), a 25μ filter screen (except all TE models) and a spanner for
disassembly.
•The only available options are wall mounting, the pressure gauges and the bleed valve (on all
models that have the filter screen).
•The optionally supplied dry pressure gauges (0 - 0 bar) have a standard /8" thread; fitting
is done using a spanner (the dial is not to be used as a handle for screwing it in) after
through drilling and tapping the pressure-gauge holes in the head. In this case the wall
mount cannot be installed. It is never permissible to use the pressure gauges as fixings for
the wall mount!
•Fixing the wall mount to the head is done using the two bolts (M8 Allen head) provided for
this purpose. Lightly tightening these is adequate for a good hold.
•The tightness of the threaded connections can be achieved with any of the usual trade
products. However, the hemp and paste from Kolmat is to be preferred. Leave one thread
turn free on the filter connector to provide a good start for the valve or connector of your
installation.
•Using removable connections will enable the filter to be easily removed from the installation
at a later date if necessary.
•The tightness between the connector and the filter head is ensured by a sealing ring; hand-
tightening is sufficient. The tightness between the head and the bowl is ensured by a sealing
ring: hand-tightening is sufficient. The spanner is for disassembly.
•If you choose the valve option, its nickel-plated brass adapter is factory-fitted with a Teflon
seal. This assembly (adapter + ¼’’ valve) must be hand-fitted to the bottom of the bowl. The
sealing between the male thread of the adapter and the bowl is ensured by an O-ring;

Tightening this assembly (adapter + ¼’’ valve) will be a maximum of ¼ turn of the O-ring
blocked against the bowl.
•The cylindrical support of the filter screen is fitted at the 2 ends with a centrifugal spinner
and a sealing cover. The purpose of the latter is to provide the sealing between the
unfiltered water and the filtered water. The largest part of the support will be placed in
centrifugal spinner.
•Fitting isolating valves upstream and downstream of the filter is advised for assisting
maintenance of the filter.
•Filling the bowl of the models TE - DUO - TIO with the treatment material (activated carbon,
polyphosphate etc.) is made easier by following the rules stated in the appendix.
•There is no model NW18TE.
4. Maint nanc
Before disassembling the bowl, close the upstream and downstream valves and release the
pressure. Maintenance and replacing the filter screen for drinking water is advised at least twice per
year. The filters graded 5, 0, 25, 50 & 00μ are intended for a single use. Cleaning them would
change the structure of the fibre, so degrading the fineness of the selected filtering and making the
filter more fragile, which could lead to tearing.
The nylon filters graded 50 & 300 μ are designed to be cleaned and re-used.
Replacement of the activated carbon in the models TE - DU - TI for drinking water is necessary
every 12 m
3
, and in other cases at least every 6 months.
The thread of the bowl must stay clean and greased for easy fitting and removal of the bowl during
its life time. The sealing ring between the head and the bowl must also remain clean and greased for
good sealing. Plan to replace it every 5 years. All slots and O-ring seating’s must remain clean and
without burrs.
Every component of the filter, even if only slightly damaged, must be replaced immediately to
ensure good performance under pressure and water-tightness of the whole filter.
5. Warranty
The choice of high-quality raw materials for manufacturing each component of your filter is the best
guarantee of giving you full satisfaction for many years of use. If, nevertheless, a component
develops a fault related to a manufacturing defect, this would be covered by a replacement of that
component under guarantee.
