SETTINGS
The GIX volumetric softener series features the Logix 760 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 amount of salt to be used for a
regeneration cycle and water hardness data.
Once set, the volumetric softener will count the number of litres
flowing through it, and it will automatically carry out a
regeneration cycle when the resin is close to depletion.
Typically, during operation, its display shows the actual time, the
current date, and the number of litres remaining before a
regeneration cycle.
During a regeneration cycle, the display shows the time needed
before completion as well as the phase it is in.
It is possible to lock the displayed information so as to avoid any
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 volumetric softeners can be
equipped, upon request, with an optional device for
resin sterililzation.
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 (B), its filter (D) and
the brine control (C), quick joints (A) at least once a
year

Lack of maintenance can cause the water 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.
