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. 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

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 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.
