Their typical installation scheme is as follows:

GENERAL WARNINGS
- This filter is an equipment for the treatment of drinking water made in compliance with the DM.
25/12 and DM. 174/04, the user must use it in full compliance with this manual in order to avoid
potential risks to health or safety;
- This filter is suitable for the filtration and treatment of drinking water as defined by the competent
authorities of the place of installation and, in any case, for liquids for food use, with PH close to
neutral;
- Do not use in presenceof water with unknown origin or microbiologically not pure, without providing
for the use of an adequate disinfection system;
- Use the filters in compliance with the operating pressures declared by the manufacturer. With
presence of high pressures in the circuit or "water hammer", protect the device by installing a
pressure reducer upstream;
- Except for special filters, use the filters with liquids at room temperature (20-25°C), however within
the limits indicated by the manufacturer. If used upstream of a boiler, it is recommended to install a
non-return valve to prevent boiling water from entering the filter;
- Do not use the containers for the filtration of compressed air, oil or gas, even at low pressures.
- Do not use these filters in environments exposed to freezing temperatures or high temperatures.
Therefore, installation outdoors or in places exposed to bad weather or ultraviolet rays is not
recommended;
- This equipment requires regular periodic maintenance in order to ensure the maintenance of the
drinking water requirements of the treated water.
INSTALLATION
The installation of the filter must be performed by qualified personnel capable of issuing a regular
declaration of conformity.
The typical filter assembly scheme is the
one shown in the image alongside.
It is advisable to create a bypass to
ensure maintenance of the filter cartridge
without eliminating the supply of water to
the users.
During the assembly phase it is important
to respect the inlet / outlet direction (IN-
OUT) indicated on the filter head. This is necessary to
allow the cartridges to work correctly.
To install the filter on the wall, use the appropriate wall
bracket (optional), which
allows for correct fixing
and proper spacing from
the wall, necessary to
ensure the opening of the
filter with the use of the
appropriate key.

It is also important not to fix the filter too close to the floor,
otherwise it becomes impossible or difficult to remove the
cartridge when carrying out the necessary maintenance.
The minimum recommended distance from the wall is 80
mm.
The minimum distance from the floor is 25 mm. The
recommended distance is instead of 100 mm (or more).
Depending on the size of the filter purchased, it is
possible to determine the fixing point of the bracket using
the following table, where the dimensions ofthe FP3 filter
can also be deduced:
Similar considerations can be made for FP2 filters.
The relative dimensions can be found in the following table:

To connect the filters to the pipes, use
flexible fittings to avoid possible tensions
caused by the pipes.
It is, in fact, preferable not to connect the
threaded pipes directly to the device.
Pipes can be used for welding, pressure
or with union.
Use fittings with cylindrical thread with
GAS or BSP pitch. Do not use fittings with
tapered threads.
When fixing the fittings to the head, avoid
using sealing pastes, hardening liquids,
silicone, hemp or other, but only Teflon
tape.
After fixing, open the taps and check that
there are no leaks or drips.

STARTING AND OPERATION OF THE FILTER
After fixing and connecting the filter to the water mains, you can start using it.
The first operation is to insert the
cartridge inside the filter.
After closing the water, open the filter
using the special key and insert the
filter cartridge necessary for the chosen
treatment inside it.
CAUTION: Remove the film or package
that wraps the cartridge. If the cartridge
has gaskets, make sure they are
correctly positioned before closing the
sump.
After placing the cartridge in the sump,
put the O-Ring in its seat and screw the
sump clockwise onto the head.
It is recommended to tighten tightly, but
by hand (without using the key). If, once
put into operation, drips occur, tighten
further with the aid of the key.
Re-open the water, check that there are no drips and vent the vessel by slightly opening the vent
screw on the head (or by pressing the appropriate button if present).
Let the water flow from a tap for a few minutes, in order to evacuate all the air and remove any dust
or dirt present in the filter, even after its assembly.
After these operations the filter is running regularly.
These operations must be repeated every time the filter cartridge is replaced or serviced.
CLEANING AND MAINTENANCE
ATTENTION: This equipment requires regular periodic maintenance in order to ensure the potability
requirements of the treated drinking water and the maintenance of improvements as declared by the
manufacturer.
In particular, periodic cleaning and maintenance operations are required, especially the filter
cartridge.
The filter must be cleaned only with a sponge and running water, every time the filter cartridge is
replaced or cleaned. Do not use detergents, solvents, alcohol, detergents or anything else that can
affect the structure of the plastic material and / or affect the potability of the treated water.
Replace thecontainer sump in theevent of acollision or if it falls to the ground. The sump(especially
the transparent one) is in fact made of fragile material, which tends to crack or chip in the event of a
collision. These micro-cracks can lead to the sudden rupture of the vessel once put under pressure
or once subject to water hammer.

When reassembling the sump, check that the O-Ring is not deteriorated (or pinched) and that it is
positioned correctly in its seat.
If the water is not used for several weeks, it is advisable to remove the cartridge from the container.
Before reinstalling the filter cartridge, wash it thoroughly and sterilize it, or fit a new cartridge.
At the end of all maintenance operations, it is advisable to let the water run for a few minutes before
using it.
To carry out maintenance, follow the steps below:
- Divert the passage of water from the filter, by acting on the by-pass (if present) or by closing the
water taps;
- Act on the screw or on the vent button, in order to reduce the internal pressure of the filter;
- Place a low container on the floor to collect the water that will drip from the filter when it is opened,
or some rags to collect the water;
- Disassemble the sump using the special plastic key. Be careful not to drop the sump. It is sensitive
to shocks;
- Be careful not to lose the O-Ring and check that it is not damaged. Otherwise, recover a new O-
Ring;
- Remove the cartridge and eliminate any dirt present in the vessel, inside the head or on the O-
Ring.
- Place a new cartridge or the removed cartridge (if washable) in the sump after cleaning it, taking
care to position the gaskets correctly, if present;
- Screw the sump onto the head (by hand);
- Reactivate the water network by keeping the vent valve open until all the air present in the network
has escaped, after which close the vent valve.
- If the filter shows dripping tighten the sump with the key;
- Regardless of the type of cartridge used, at the end of each cleaning or maintenance operation, let
the water run for a few minutes before using it.
The frequency of intervention is linked to the type of cartridges used:
CARTRIDGES FOR SEDIMENTS: (wire wound, Melt Blown, pleated, RLA, etc.):
Replace or wash the sediment cartridges within 2-5 months, or if necessary, if a significant pressure
drop is detected. Washable cartridges (RLA) can be used multiple times.
They must be washed and disinfected periodically, as specified below.
1). Wash thoroughly under running water.
2). Immerse the cartridge in disinfectant that does not alter / corrode the structure of the cartridge
itself, for 5 (five) minutes.
3). Remove the cartridge from the disinfectant liquid and rinse thoroughly.
The polypropylene cartridges (Melt Blown) must be thoroughly washed before installation, to
eliminate the residues of the antistatic compound used for processing of the fibers.
CARBON CARTRIDGES:
Replace the active carbon cartridges within 3-4 months, or if necessary if you perceive a taste of
chlorine, bad smells or tastes.
Before installing a new cartridge, rinse thoroughly to remove any carbon dust residues.
SALT POLYPHOSPHATE:
Replace the polyphosphate salt cartridges within 4-6 months or, in any case, when the
polyphosphate salt is exhausted.

In case of replacement of cartridges or of the entire filter, follow the correct disposal
rules provided by the state or region in which the product is installed.
In general, these rules prescribe:
- CARTRIDGES: disposal as unsorted waste as it is dirty or soiled material;
- FILTERS AND VASES: recycling with plastic products as they are made of
polypropylene. However, any metal parts must first be removed.
