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.

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. Maintenance

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, 10, 25, 50 & 100µ 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 150 & 300 µ are designed to be cleaned and re-used.
Replacement of the activated carbon in the models TE - DUO - TIO for drinking water is necessary
3
every 12 m , 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 seatings 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.
