SETTINGS
The GIX chronometric softner series features the
Logix 740 valve.
Thanks to their user-friendly approach, they can easily
be set. They have 4 buttons that are used to set
current time, regeneration time, the days on which
regeneration shall be carried out or the number of
days elapsing between two regeneration cycles.
Once set, this chronometric softener will automatically
carry out the regeneration cycles.
When operating, it displays current time and day as
well as the days on which rigeneration is scheduled.
During a regeneration cycle, the displays shows time
to completion as well as the stage it is in.
The information displpayed can be locked so as to
avoid hazardous data modification.
INSTALLATION INSTRUCTIONS:
We suggest installing the equipment:
A-NON-RETURN VALVE
B-OUTLET TAP
C-BY-PASS TAP
D-INLET TAP
E-OVERFLOW PIPE
F-UNLOADING PIPE
Install on the water outlet a check valve (A) (DVGW,
DIN 1988 T2) to protect the water softener from a
reverse flow of hot water that could cause damage.

CHOOSING THE PLACE OF INSTALLATION:
Waste water resulting from the regeneration must be
funneled into the floor sink by the flexible pipe.
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
2.8 bar
If the water softener is near a boiler, check that the
pipes and the water softener itself are not subjected to
overheating. If possible, install a pipe that keeps a few
meters’ distance (at least 3) between the outlet of the
water softener and the inlet of the boiler.
Keep away from corrosive or acid products.
CONNECTION TO THE DRAIN SYSTEM (A).
The drain pipe is not flattened or bent,as water should
flow without impedements.
THE OVERFILL PROTECTION PIPE (B)
Insert flexible pipe 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 .
ELECTRIC AND ELECTRONIC COMPONENTS:
A-OPTICAL SENSOR
B-AC ADAPTER INPUT
C-MAIN MOTOR & OPTICAL SENSOR
D-VOLUMETRIC TURBINE INPUT
E-CHLORINE GENERATOR OUTLET
RESIN STERILIZATION AND SALT ALARM
(OPTIONAL)

The GIX series chronometric softeners can be
equipped, upon request, with an optional device for
resin sterilization.
Such device is installed in the body of the valve and
connected to the timer connector.
Once installed, the timer will start it during a
regeneration cycle.
Such device uses salt so as to carry out resin
disinfection.
If salt is not present, the device will not start. Once the
regeneration cycle is over, an orange led light will turn
on –this means that salt shall be added in brine.
MAINTENANCE FOR THE INSTALLER:
For the equipment to work in optimal conditions, we
suggest performing the following operations
periodically: Clean the injector (fig. 6, B), its filter (fig.
6, D) and the brine control (fig. 6,C) at least once a
year

lack of maintenance can cause the softener to
malfunction
The filling of the brine (obstructed ejector) and the lack
of suction of the brine (air infiltration in the rapid
connections) are the problems that could occur due to
lack of maintenance by the installer.
FOR THE USER:
Maintenance for the user only consists in refilling the
brine periodically with sodium chloride (NaCl,
common salt). If salt is lacking, the water softener will
not be able to soften the water.
