3.3 CONNECTION TO THE WATER SYSTEM

The connection to the water system must be done according
to all applicable norms, following the instructions of the manu-
facturer and qualified personnel.
During the installation use pipes, hoses, valves and compo-
nents which comply with applicable norms on hygienic safety
DM 174/2004. They must be kept in their sealed package
until the moment of installation to preserve their hygienic sa-
fety. It is forbidden to use components that are not suitable for
drinking water contact, or components which hygienic safety
was compromised, as they could corrupt the quality of treated
water and the equipment itself.
We suggest using the method of installation described in fig.
3, as it includes a by-pass to avoid interruptions in the supply
water flow in case the equipment should need to be turned
off for maintenance. The by-pass will allow you to use wa-
ter in your structure even while the water softener is under
maintenance.
Check for the presence of hygienic security taps on the
entrance (INLET) and exit (OUTLET) of the equipment (fig.
2), remove them only during this phase and not before.
3.3.1 QUICK JOINTS
The pipes are connected to the valve by quick joints.
To connect a pipe it is necessary to insert it all the way in.
The metal inserts of the quick joints will prevent the pipe from
disconnection.
To disconnect the pipe it is necessary to depressurize the
tank, then press on the black ring that surrounds the pipe next
to the insertion, and extract the pipe (fig. 4).
Ensure that:
• The water inlet (fig. 3, G) and outlet (fig. 3, H) pipes comply
with the norms on drinking water pipes.
• The water inlet pipe has an internal diameter of at least 8
mm.
We suggest installing a filter before the inlet pipe (fig. 3, G), to
clean the feed water.
Install on the water outlet a check valve (fig. 3, A) (DVGW, DIN
1988 T2) to protect the water softener from a reverse flow of
hot water that could cause damage.
Install a tap to take a sample of the outlet water, to test its
hardness.
Connect the water inlet and outlet pipes to the 3/8"G or 3/4"G
joints in the package, tightening them safely (fig. 2 and fig.
3, D, B).
Insert the joints all the way into the valve (fig. 4).
All pipes must be free, not crushed or constricted.
3.4 CONNECTION TO THE DRAIN SYSTEM
Waste water resulting from the regeneration must be funneled
into the floor sink by the plastic flexible pipe with an 8 mm
internal diameter (fig.3, F) included in the package.
Very often, the main cause for the water softener malfunctio-
ning is that this tube was not installed correctly. (fig. 5, A)
Insert the drain pipe in its joint (fig. 2, "DRAIN") and place the
other end of the tube in the floor sink, ensuring that:
• If the floor sink is placed higher than the water softener,
the maximum height acceptable is 1.8 metres, provided
that the pipe is not longer than 5 metres and the pressure
of the water system is at least 3 bar (fig. 6).
• The pipe is not flattened or bent, as water should flow
without impedements (fig. 5, A);
• The drain pipe must never be directly connected to a si-
Instruction manual AL series
phon or to other drain pipes, to avoid reverse flows of water
and the contamination of the water softener.
• Keep the drain pipe suspended over and not immer-
sed in the water of the sink.
• Ensure that the pipe does not come out when the wa-
ter softener is doing the regeneration.
3.5 CONNECTION TO THE BRINE TANK
The installer must make sure the pipes and the joints con-
necting the valve and the brine are perfectly sealed, to avoid
air infiltration (fig. 8, A).
3.6 CONNECTION TO THE OVERFILL PROTECTION PIPE
The installation of an overfill protection pipe (fig. 3, E) on the
brine tank allows for the draining of possible excess of water
in the brine, that may be caused by faulty refills or working
malfunctions.
Drill a hole of 17 mm in diameter in the brine tank, around 10
cm under the lid (fig. 1, E), and tighten the overfill protection
quick joint (fig. 3, I). Insert the green flexible pipe (included
in the package) in the quick joint, then connect the pipe to a
floor sink that must be placed under the quick joint, because
the water that may come out will not be pressurized (fig. 5, B).
Do not put the overfill pipe in the same floor sink used for the
drain pipe, to prevent any possible reverse flows of water in
the brine.
3.7 CONNECTION TO THE ELECTRICITY GRID
Make sure that the voltage of the electricity grid is compatible
with the voltage needed by the equipment.
Make sure that the plug is compatible with the socket. If in-
compatible, let qualified personnel change it. They will al-
so check that the cables are compatible with the absorbed
power.
Installation must be carried out in accordance with the
law on electrical systems, CEI 64.8.
This equipment was built in accordance with the essential
safety requirements set by the following European regulations:
• Low Voltage Directive 2006/95/CEE
• Electromagnetic Compatibility Directive 2004/108/CEE
• Norms: EN 55014-1 (2006)+A1+A2, EN 55014-2
(1997)+A1+A2, EN 61000-3-2 (2006)+A1+A2, EN
610003-3 (2008)
• Product norms IEC/EN 60335-1:2010 on the Electrical
safety of electrical machinery for domestic use and similar
• It uses components which comply with UL/CSA/VDE
• It conforms to the RoHS norm.
After the installation is complete, before opening the wa-
ter inlet and outlet taps, read chapter 4 "ACTIVATION".
4) ACTIVATION
To activate the water softener you must: select your language,
set current the day and time and run the installation program.
ATTENTION! In order to store the data, follow the instructions
carefully. You will have to disconnect and reconnect the power
connector (fig. 9, A) while pressing and holding the buttons
next to the display.

You can select one of the following languages: Italian, English,
French, German and Spanish.
To select your language:
- Insert the plug (fig. 9, B) in the socket
- Insert the connector (fig. 9, A) in the valve while pressing
