efficiency and durability. This philosophy is accredited through certification by external bodies.
The highest efficiency of the system is obtained with correct operation and maintenance, please
properly follow the indications in this manual throughout the life of the product. We invite you
to visit our website: www.itmfilters.com for more information about our products and our
company policies.
1.1 Filter identification
The filter is identified with the following decal:
1.2 Basic concepts
Filtration surface: Area that allows water to pass while retaining suspended particles.
Recommended flow: Optimal filtration must take into account the quality of the source water
and its use. The quality of the source water is divided into 4 sections, which have maximum
theoretical flows. The sectorization corresponds to the particles per million diluted in the water.
Stretch 1: 0-50 ppm.
Stretch 2: 50-100 ppm.
Stretch 3: 100/200 ppm.
Stretch 4: >200 ppm.
Loss of pressure: It is the difference in load produced between two points of the same flow. The
friction of the water with the filter medium produces a loss of energy. The diluted substances
are trapped in the mesh generating a decrease in the porosity of the filter medium, which causes
an increase in the pressure drop. The pressure drop measurement is carried out by means of a
pressure tap on the inlet manifold and another one on the outlet manifold.

3. Installation
1. Place the filter on a flat surface. If more than one filter is purchased and they are
stacked, they must be separated by unscrewing the union on the upper supports.
2. Position the inlet and outlet manifolds, fixing the flanges with their corresponding
gaskets.
3. Connect the drainpipes and direct to the desired area.
4. Filter filling. First fill the water filter halfway. Open the top cover and pour the filter
material slowly to avoid damage to the internal structure. The amount of sand required
is indicated in the technical sheet (Page 2).
5. Place the pressure gauges, one on the water inlet manifold and the other on the filtered
water outlet manifold.
6. Check that the unions are tight, turn on the water supply and verify that there is no leak.
7. Carry out a first cleaning to remove possible impurities from the sand.
8. Filtering. Open the water flow at the recommended flow rate (depending on the quality
of the water) and at a working pressure of 8 kg/cm².
9. When the pressure gauges indicate a pressure difference equal to or greater than 0.5
kg/cm², clean the filter by reversing the direction of the water.
4. Operation
Sand filtration is a highly efficient and in-depth filtration method. It consists in the physical
separation between water and the substances that are suspended in it. The water descends
through the filter bed of sand where impurities are trapped, and the system of arms allows the
filtered water to escape.
When the sand filter becomes clogged, it produces a pressure difference between the water
inlet and outlet. The cleaning cycle begins when a pressure difference of 0.5 kg/cm is reached.
The cleaning cycle consists in reversing the direction of circulation: the water rises and carries
all the particles trapped in the sand filter bed and it is expelled.
5. Maintenance and spare parts
5.1 Maintenance
1. Avoid leaving the filter without water for proper maintenance of the filter material. If
the sand becomes dry and caked, open the lower mouth of the filter, empty its contents
and replace it. In case the sand does not evacuate properly, connect the water flow to
facilitate its exit.
2. Proper filter maintenance includes checking the condition of the paint. Damage caused
by corrosion must be corrected.
