• 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.
8.3 WATER NETWORK CONNECTION
Make sure the pressure of the water network ranges between
2 bar and 8 bar; if pressure is higher than 8 bar, the installa-
tion of a pressure reducer is required. If it is lower than 2 bar,
the water softener will not function properly.
For a higher security, install a tap on the inlet pipe and
another tap on the outlet pipe (fig. 3, B, D); this allows to stop
the water in case of need.
Install a non-return valve (DVGW, DIN 1988 T2) on the water
softener outlet (fig. 3, A) to prevent hot water to return to the
softener as it may damage the fixture.
We advise you to perform the installation described in fig.
3, because it will allow you to use water in your fixture also
during maintenance.
At the end of installation, before you open the inlet and outlet
taps, the water softener must be set to work (see paragraph
11).
8.4 UNLOADING SYSTEM CONNECTION
While regenerating, the outgoing water must be unloaded
being conveyed through a plastic flexible pipe (included in the
package) and into the nearest unloading system.
Install the unloading pipe following the instructions below,
as a poor installation will cause malfunctioning to the water
softener:
• If possible, the unloading point must be at floor level;
• If the unloading point is placed higher than the water softe-
ner, the maximum height acceptable is 1.8 metres, provi-
ded that the distance is not longer than 5 metres and the
pressure of the supply water network is at least 2.8 bar
(fig. 5).
• Make surethe pipe is not flattened or bent, as water should
flow out without running into obstacles (fig. 4, A);
• The unloading system must never be directly connected
to a siphon or to other unloading pipes, in order to prevent
returns or pollution into the water softener
8.5 BRINE CONNECTION
The installer must make sure the connection between the
valve and the brine must be perfectly sealed and airtight (fig.
8, D).
8.6 OVERFLOW PIPE CONNECTION
Install the overflow union joint (included in the package) on the
brine tank, to allow the unloading of possible excess of water
in the brine that may be caused by irregular refill or defects
in the functioning. Drill a hole in the brine, tight the overflow
union joint, insert the flexible pipe on the hose fitting, connect
the pipe to an unloading system placed lower than the union
joint, to allow the water to come out simply by falling rather
than by pressure (fig. 3, E and fig. 4, B).
Do not connect the overflow pipe to the unloading pipe of the
water softener, in order to prevent any possible return of water
in the brine.

9) SETTING THE TIMER

9.1 MINI - MAXI
The MINI - MAXI water softener can be programmed in a
quick and easy way. It is provided with four buttons allowing to
10
MINI - MAXI
set time, day and salt amount for regeneration (fig. 9).
During service, the display shows the time, the current day,
and, if programmed, the regeneration days.
During regeneration, the display shows the residual time until
the end of the operation, and the current step (fig. 18).
9.2 PLUGGING IN THE FIXTURE
Plug in the fixture and connect the connector to the timer (fig.
6, G). The display (fig. 9, E) will show the time.
If "Err3" appears instead, wait for the valve to position to the
correct step. The error message will disappear and the display
will show the time.
9.3 SETTING DAY AND TIME
1) Press N and the display will flash.
ih
2) Using the buttons set the current time (fig. 10).
3) Press N to confirm.
Now, on the higher part of the display, a little triangle indi-
cating the day will appear (fig. 11).
1) Press Nand the little triangle will flash.
2) Move it using the buttons
12)
3) Press N to confirm.
9.4) SETTING REGENERATION TIME
On the left side of the display, a little triangle will point to the
words "regen time".
1) Press N and the display will flash.
ih
2) Using the buttons select the regeneration time (fig.
13).
3) Press N to confirm.
9.5 SETTING REGENERATION DAY
On the display, you will see a number indicating the lapse of
time between a regeneration and the next, and a little triangle
under the word "DAYS" (fig. 14).
