WARNING & SAFETY INSTRUCTIONS
Page 3
Before you begin the installation of the water softener, we advise you
read and carefully follow the instructions contained in this manual. It
contains important information about safety, installation, use and
maintenance of the product. The actual system that you have received,
may differ from the pictures/illustrations/descriptions in this Technical
Manual.
Failure to follow the instructions could cause personal injury or damage
to the appliance or property. Only when installed, commissioned and
serviced correctly, the water softener will offer you many years of
trouble-free operation.
The water softener is intended to 'soften' the water, meaning it will
remove hardness minerals; it will not necessarily remove other
contaminants present in the water. The water softener will not purify
polluted water or make it safe to drink!
Installation of the water softener should only be undertaken by a
competent person, aware of the local codes in force. All plumbing and
electrical connections must be done in accordance with local codes.
Before setting up the water softener, make sure to check it for any
externally visible damage; do not install or use when damaged.
Use a hand truck to transport the water softener. To prevent accident or
injury, do not hoist the water softener over your shoulder. Do not lay the
water softener on its side.
Keep this Technical Manual in a safe place and ensure that new users are
familiar with the content.
The water softener is designed and manufactured in accordance with
current safety requirements and regulations. Incorrect repairs can result
inunforeseen danger for the user, forwhich the manufacturer cannot be
held responsible. Therefore repairs should only be undertaken by a
competent technician, familiar and trained for this product.
In respect of the environment, this water softener should be disposed of
in accordance with Waste Electrical and Electronic Equipment
requirements.Refertonational/locallawsandcodesforcorrectrecycling
of this water softener.

OPERATING CONDITIONS & REQUIREMENTS
Page 4
OPERATING PRESSURE: min. 1,4 / max. 8,3 bar
this system is configured to perform optimally at an operating
pressureof3bar(±½bar);incaseofalowerorhigheroperating
pressure the performance may be affected negatively!
check water pressure regularly.
take into account that night time water pressure may be
considerably higher than day time water pressure.
install a pressure reducer ahead of the water softener if
necessary.
OPERATING TEMPERATURE: min. 2 / max. 48 °C
do not install the water softener in an environment where high
ambient temperatures (e.g. unvented boiler house) or freezing
temperatures can occur.
the water softener cannot be exposed to outdoor elements,
such as direct sunlight or atmospheric precipitation.
do not install the water softener too close to a water heater;
keep at least 3 m of piping between the outlet of the water
softener and the inlet of the water heater; water heaters can
sometimes transmit heat back down the cold pipe into the
control valve; always install a check valve at the outlet of the
water softener.
ELECTRICAL CONNECTION: 230V-50Hz
this water softener only works on 24VAC; it is equipped with a
230/24V-50Hz transformer; always use it in combination with
the supplied transformer.
makesuretoplugthetransformerintoapoweroutlet,whichis
installed in a dry location, with the proper rating and over-
current protection.

INSTALLATION
Page 5
Picture 1&10
To facilitatethe installation,youmay want to remove the salt
lid and main coverfrom the water softener.
1. Remove the salt lid.
2. Remove the rivets at the rear of the main cover.
3. Carefully lift the main cover from the water softener.
INLET & OUTLET
Check the waterpressure at the place of installation of
the water softener; it should never exceed 8,3 bar.
In case of high concentration of impurities in the inlet
water, we recommend the installation of a sediment filter,
ahead of the water softener.
We strongly recommend the use of flexible hoses to
connect the water softenerto the waterdistributionsystem;
usehoseswithalargediameterinordertolimit thepressure
loss.
If the water softener is not equipped with the factory
bypass (optional), we strongly recommend to install a 3-
valve bypass system (not included with this product!) to
isolate the water softener from the water distribution
system in case of repairs. It allows to turn off the water to
the water softener, while maintaining (untreated) water
supply to the user.

DRAIN
We recommend the useof a stand pipe with air trap.
To prevent backflow from the sewerage system into the
water softener, always make sure to have an air gap
betweenthe end ofthedrain hose andthe sewerage system
itself; as a rule of thumb, the air gap should be minimum 2x
the diameter of thedrain hose.
Always use separate drain hoses for the control valve
(evacuation of rinse water) and the softener cabinet's
overflow.
Lay-out the drain hosesin such a waythat pressure loss
is minimized; avoid kinks and unnecessary elevations.
Make sure that the sewerage system is suitable for the
rinse water flow rateof the water softener.
Picture 4

than the water softener.
3. Connect a 13 mm hose to the cabinet overflow elbow,
located at the back side of the water softener; secure it
by means of a clamp.
4. Run the drain hose to the sewerage system and connect
it to the stand pipe assuring sufficient air gap. This drain
line does NOT operate under pressure, so it may NOT be
installed higher than the water softener.
ELECTRICAL

POWER-UP
After power-up, the display will show the installed software
version for 5 seconds, f.e.:
Afterwards it will automatically revert back to the service
display.
POWER FAILURE
In the event of a power failure, the program will remain
stored in the NOVRAM®duringan undefined period, while an
incorporated SuperCap (capacitor) will maintain the correct
time of dayduring a period ofseveral hours; consequently, in
case of prolonged powerfailure,the timeof day might not be
maintained; if this happens, the time of day will be reset to
8:00 when the power supply is re-established, while the
indication will flash, indicating that the time of day needs to
be set.
When the power failure occurs during the execution of an
automatic regeneration, the control valve will immediately
return to the service position; when the power supply is re-
established, the control valve will stay in the service position
for 60 sec. and restart a complete regeneration from the
beginning.
TIMER FAILURE
In the event of a timer failure, the display will show the
message:
In such case, entering one of the programming levels can
possibly solve the problem. However if the problem persists,
professional service is required.
SERVICE MODE
In service mode the display shows the time of day, the
remaining capacity and the water usage indicator:
REGENERATION MODE
In regeneration mode the display shows the actual
regeneration cycle and, where relevant, the total remaining
regeneration time and remaining cycle time:
The control valve can be reset to service mode at any timeby
pressing the scroll button, as such manually advancing it
through the regeneration cycles.
CHECKING THE FLOW METER
In case of water usage, the remaining capacity counter in the
service displaywill count back per unit, i.e. per litre. This way
the correct functioning of the water meter can be verified.
MANUAL REGENERATION
It is possible to manually initiate a regeneration.
1. Press the scroll button repeatedly until the display
shows:
If the control valve is left in this position, the
countdown timer will countdown to 0 sec and start a
regeneration.
To cancel this mode, press the scrollbuttonbefore
the countdown timer has reached 0 sec; the control
valve will return to the service mode.
2. Press the scroll button again if you want to manually
advance the control valve to the next regeneration cycle.

MAINTENANCE
Page 11
ROUTINE CHECKS
Regularlytheusershouldperformabasicchecktoverifyifthe
water softener is functioning correctly, on the basis of the
following control points:
1. Check settings of electronic control panel.
2. Measure water hardness before/after water softener.
3. Check drain line from control valve; there shouldn’t be
any waterflow (unless water softeneris in regeneration).
4. Check drain line from cabinet overflow; there shouldn’t
be any water flow.
5. Check water softener and surrounding area; there
shouldn’t be any water leakages.
BYPASSING THE WATER SOFTENER
Occasionally it may be necessary to put the water softener
hydraulically in bypass, i.e. to isolate it from the water
distribution system; f.e.:
in case of an urgent technical problem;
when it is not necessary to supply treated water to the
house/application (refill swimming pool, irrigation,...).

WATER CONDITIONER SALT
Picture 10
The water softener needs 'brine' for its periodic
regenerations. This brine solution is made from water, that is
automatically dosed in the brine cabinet by the control valve,
and water conditioner salt. The user should make sure that
the brine cabinet is always kept full of water conditionersalt.
Thereforeheshouldperiodicallycheckthesaltlevelinsidethe
brine cabinet and refill it if necessary. The salt lid can be
removed completely to facilitate refilling.
Ideally the level of water conditioner salt inside the brine
cabinet is kept between 1/3 and 2/3. A lower level of water
conditioner salt can cause insufficient brine saturation,
resultinginalossofsofteningcapacity.Ahigherlevelofwater
conditioner salt can cause salt bridging (hard crust or salt
bridges in the brine cabinet). When you suspect salt bridging:
carefully pound on the outside of the brine cabinet to
break loose the salt bridges;
usingabroom(orlikeblunttool)carefullypushthesaltto
break it apart;
pour warm water over the top of the salt to dissolve it.
BRINE CABINET
To retain the appearance of the water softener, simply wipe
it with a damp cloth or clean it with a mild soap solution;
never use abrasive cleaners, ammonia or solvents.
RESIN CLEANER
Other contaminants (f.e. iron) present in the feed water can
cause the resin bed to foul up, resulting in a loss of softening
capacity. An approved resin cleaner can be used periodically
to thoroughly clean the resin bed.
SANITIZING THE WATER SOFTENER
This water softener is manufactured from premium quality
material and assembled insafe conditions toassureit is clean
and sanitary. If installed and serviced correctly, this water
softener will not infect or contaminate your water supply.
However, as in any 'device' plumbed-in in your water
distribution system, a proliferation of bacteria is possible,
especially in case of 'stagnant water'. Therefore this water
softener is equipped with a 'days override' feature, that will
automatically rinse the resin bed periodically, even in case of
low or absence of water usage.
If the power supply to the water softener is disconnected for
a longer period of time, we recommend, when the power
supply is re-established, to manually initiate a complete
regeneration.
