ENGLISH

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 needs to be turned off, or if 

maintenance is necessary.

Ensure that:

•  The water inlet and outlet pipes (fig. 3) 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, 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.

All pipes must be free, not crushed or constricted.

Check for the presence of hygienic security taps on the 

entrance and exit of the equipment. Remove them only 

during this phase and not before.

 3.4 CONNECTION TO THE DRAIN SYSTEM

Waste water resulting from the regeneration must be funneled 

into the floor sink by the flexible pipe (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. 4, A)

Tighten the rubber-holding joint included in the package (fig. 

2, C) to the equipment flange, insert the drain pipe (fig. 3, F) in 

the rubber-holding joint and place the other end of the tube in 

the floor sink, ensuring that:

•  f 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 2.8 bar (fig. 5).

•  The pipe is not flattened or bent, as water should flow 

without impedements (fig. 4, A);

•  The drain pipe must never be directly connected to a si-

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 valve is connected to the salt container by a pipe with a 

diameter of 6 mm. Both the pipe ends are inserted into quick 

joints (fig. 6, A).

To disconnect the pipe it is necessary to pull out the red secu-

rity clip, then press on the black ring that surrounds the pipe 

next to the insertion, and extract the pipe.

To connect the tube safely, ensure that it is inserted all the 

way in.

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. 6, 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, and tighten the overfill protection quick joint 

(fig. 3, H). Insert the green flexible pipe (included in the packa-

ge) 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. 4, B).

Do not put the overfill protection pipe (fig. 3, E) in the same 

floor sink used for the drain pipe (fig. 3, F), 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.

IInstallation 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:

•  The 2014/30/UE Electromagnetic Compatibility Directive

• Norme: 2014/30/EU/(EMC), EN 55014-1:2017, 

E N 6 1 0 0 0 - 3 - 2 : 2 0 1 4 ,   E N   6 1 0 0 0 - 3 - 3 : 2 0 1 3 , 

E N   5 5 0 1 4 - 2 : 2 0 1 5   2 0 1 4 / 3 5 / E U ( L V D ) ,   E N 

60335-1:2012+A11:2014+A13:2017

•  Product norms IEC/EN 60335-1:2010 on the Electrical 

safety of electrical machinery for domestic use and similar

•  It uses UL/CSA/VDE homologated components

•  It is RoHS compliant

After the installation is complete, before opening the wa-

ter inlet and outlet taps, read chapter 4 “ACTIVATION”.

 4) ACTIVATION

After the installation is complete, follow the procedure below:

1.  Keep the water inlet and outlet taps closed (fig. 3, B, D), 

then plug in the equipment.

2.  Wait for the time to appear on the display; this is the 

signal that the valve is working.

3.  Press and hold the   button for 5 seconds to start a 

manual regeneration cycle.

4.  Wait for the display to show C1.

5.  Unplug the equipment.

6.  Slowly open the water inlet by half (fig. 3, D) and leave it 

in this position for about 2 minutes. Afterwards, open the 

water inlet completely and let the water flow abundantly 

from the drain pipe;

7.  Pour water in the brine tank until it covers the air check 

(fig. 1, D);

8.  Plug in the fixture again.

9.  Press the 

N

 and 

h

 buttons at the same time to pass to 

step C2. Press the buttons again to pass to step C4 and 

again to get to step C8.

10. Wait for the water softener to complete the cycle (it will 

only take a few minutes) and to position on working mode.

11. Press and hold again the   button for 5 seconds to start 

a manual regeneration cycle.

Wait a few seconds for the valve to position itself on phase 

C1.

12. Press the 

N

 and 

h

 buttons to pass to step C2, “SALT 

INSERTION”. Check that the water in the brine tank is 

sucked.

13. Press the 

N

 and 

h

 buttons at the same time to pass to 

step C5.

14. Wait for the cycle to finish (it will take about 10 minutes).

15. Open the inlet and outlet taps completely (fig. 3, B, D) and 

close the by-pass tap (fig. 3, C).

16. Add salt to the brine tank until a little bit more than half of
