7) MANUAL SETTINGS

7.1 MANUAL REGENERATION
To perform a manual regeneration, press the
seconds.
When the regeneration begins, the writing "REGENERATION
OF RESINS" will appear on the display.
During the regeneration, the display will show the current step
and the time left until completion.
To skip to the next step, press and hold the
seconds.
The regeneration is made of the following 4 phases:
B1 Service mode: the machine is operational. Water from
the system comes in, and softened water comes out.
B3 Backwash: it is the quick rinse phase. Water flows in
the tank backwash, mixing and rinsing the resins and
carrying to the drain any impurities that may have formed
in the water softener during its work.
B5 Brine sucking and slow rinse: during the first part, salt
water is sucked and sent in contact with the resins, to-
gether with the hypochlorite produced by the electrodes
(fig. 10, A). At the end of this phase, a slow resin rinse is
performed.
B7 Refill and quick wash: water is sent to the brine tank in
order to melt the correct amount of salt that will be used
in the next regeneration. At the same time, a resin rinse
is performed.
During steps B3, B5 and B7 the water softener will send water
to the drain.
When the machine is in service mode, the water softener does
not send water to the drain.
Water is always supplied during regeneration.
See CHART 3, paragraph 5.5 for the duration of every step.
7.2 DELAYED MANUAL REGENERATION
By pressing the button, (R ) will be visible on the display.

The softener will carry out a regeneration cycle at the time set
in the program (paragraph 5.3).
7.3 RETURNING TO SERVICE MODE
If you want to interrupt a regeneration and make the valve
return to service mode, press the
time.
7.4 RESIN RINSE PROGRAM
The water softener may sometimes dispense salt water,this
problem can be caused by a lack of hydric pressure during
regeneration, which prevents the water softener from being
properly rinsed.
Thanks to the resin rinse program, the tank will be emptied of
the salt water in a few minutes, and soft water will be supplied
again.
In order to star the rinse cycle:
+ keys until you read "RESIN RINSE"
• Press the and
OK
on the display.
The water softener will rinse the resins in Backwash mode
(B3) for 5 minutes, then will return to Service mode.
It is possible to interrupt the rinse step at any moment, pres-
sing the + key for 5 seconds. The water softener will inter-
rupt the cycle and will return will automatically get in opera-
ting mode.
This is a very useful function also to decrease pressure in the
cylinder, in case maintenance procedures are to be carried
out

8) SETTING WATER HARDNESS USING
THE MIXER
The water softener supplies hardness-free drinking water.
In some cases, a residual level of water hardness is es-
sential.
By tightening the mixer screw, a small quantity of non-softe-
ned water will mix with softened water near the outlet, raising
the hardness levels of the outlet water.
The more you tighten the mixer screw (fig. 3, M) the more the
hardness levels in the outlet water will rise.
Please remember that this operation must be carried out very
carefully by the installer, who will have to measure correct
water hardness at the end of the procedure.
9) MAINTENANCE FOR THE INSTALLER
During all maintenance operations, all necessary precautions
must be adopted to preserve the hygienic integrity of the equi-
pment.
Reparations and maintenance must be carried out using ori-
ginal replacements.
9.1 PERIODIC MAINTENANCE
For the equipment to work in optimal conditions, we suggest
performing the following operations periodically:
- Clean the brine with warm water and remove any sediment
from the suction pipe (fig. 1, B) every six months;
For external cleaning use a damp cloth and warm water.
Do not use detergents or other chemical substances.
- Check and clean the injector (fig. 10, B), its filter (fig. 10, C)
and the electrodes (fig. 10,A) at least once a year, following
the instructions reported below:
1. Close the water inlet and outlet taps (fig. 3, B, D)
2. Simultaneously press the
read "RESIN RINSE" on the display
3. Wait 30 seconds then disconnect the transformer connec-
tor from the timer (fig.9, A)
4. Unscrew the caps (fig. 10, D) and remove the ejector (fig.
10, B), the filter (fig. 10, C) and the electrode holder.
5. Clean the components with water and make sure the hole
in the ejector is not blocked (fig. 10, B).
6. Put the parts back in their place carefully.
7. Take out the two electrodes, (fig. 10, A) inspect and clean
them by using a wet cloth; in case of clear wear and tear
signs, replace them.
8. Put them back in the right position.
9. Open again the water inlet and outlet taps.
10. Reconnect the transformer connector to the timer (fig. 9,
A) and let the resin rinse cycle end (around 5 minutes).
9.2 RESIN PRESERVATION AND ACTIVATION AFTER
A LONG PERIOD OF INACTIVITY
If the water softener is not to be used for more than 30 days,
it is necessary to do a double regeneration first.
Inactivity of the device for more than 12 months is not advi-
sable, and switching on the system after such a long period
of non-use is not authorized.
If the period of inactivity is shorter than 12 months, it is ne-
cessary to perform a resin rinse (see paragraph 7.4) and a
manual regeneration (see paragraph 7.1) before reactivating
the equipment.
9.3 DISCONNECTING THE EQUIPMENT
1. Close the inlet and outlet water taps (fig. 11,A)
2. Simultaneously press the
