Cintropur NW 18 Montage-, Bedienungs- Und Wartungsanleitung Seite 8

NW 18 – 25 – 32 & 25 TE (-CTN) + NW 32TE + DUO (-CTN) + TIO
Instructions for assembly, use and maintenance
1. Possible applications
The range of water filters CINTROPUR
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
dechlorination, removal of odours, improvement of taste, reduction of pesticides and herbicides.
2. Technical description
Installation and use of the filters NW 18 - 25 - 32 - 25 TE (-CTN) - 32 TE - DUO (-CTN) - TIO must be
comply with the technical requirements stated in the following table:

3. Assembly 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
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 1"), 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 - 10 bar) have a standard 1/8" thread; fitting is
done using a spanner (the dial is not to be used as a handle for screwing it in) after through
