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 in this
Owner's 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 Owner's 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 in unforeseen danger for the user, for which 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. Refer to national/local laws and codes for
correct recycling of this water softener.

OPERATING CONDITIONS & REQUIREMENTS
Page 4
OPERATING PRESSURE: min. 1,4 / max. 8,3 bar
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.
make sure to plug the transformer into a power outlet,
which is installed in a dry location, with the proper rating
and over-current protection.

INSTALLATION
Page 5
To facilitate the installation process, remove the salt lid and main cover from the water softener.
INLET & OUTLET
Check the water pressure 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 softener to the water distribution
system; use hoses with a large diameter in order to limit
the pressure 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.

INSTALLATION
Page 6
DRAIN
We recommend the use of a stand pipe with air trap.
To prevent backflow from the drainage system into
the water softener, always make sure to have an air gap
between the end of the drain line and the drainage system
itself; as a rule of thumb, the air gap should be minimum
2x the diameter of the drain line.
Always use separate drain lines for the control valve
(evacuation of rinse water) and the softener cabinet's
overflow.
Lay-out the drain hoses in such a way that pressure
loss is minimized; avoid kinks and unnecessary elevations.
1. Connect a 13 mm hose to the drain solenoid of the
control valve (); secure it by means of a clamp.
2. Run the drain hose to the drainage system and
connect it to the stand pipe assuring sufficient air
gap. This drain line operates under pressure, so it may
be installed higher than the water softener.
3. Connect a 13 mm hose to the 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 drainage 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
1. Plug the transformer into an electrical outlet.
2. Plug the transformers output lead into the socket on
the water softeners power cord; secure it by means
of the clamp.

START-UP

2. Make sure the electronic controller of the water
softener is 'in service'.
3. Open the mains water supply.
4. Open a cold treated water faucet nearby the water
softener and let the water run for a few minutes until
all foreign material that may have resulted from the
installation is washed out; close the tap.
5. Gently pressurize the water softener, by putting it
into service:
factory bypass:
1. open the 'outlet' valve;
2. slowly open the 'inlet' valve.
3-valve bypass:
1. close the 'bypass' valve;
2. open the 'outlet' valve;
3. slowly open the 'inlet' valve.
6. After 2-3 minutes, open a cold treated water faucet
nearby the water softener and let the water run for a
few minutes until all air is purged from the
installation; close the tap.
7. Check the water softener and all hydraulic
connections for leaks.
BRINE CABINET

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.
The POWER led will light up.
POWER FAILURE
In the event of a power failure, the program will remain
stored in the NOVRAM® during an undefined period, while
an incorporated SuperCap (capacitor) will maintain the
correct time of day during a period of several hours;
consequently, in case of prolonged power failure, the time
of day might not be maintained; if this happens, the time
of day indication will flash when the power supply is re-
established, 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 and the
remaining number of days:
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 time
by 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 display will count back per unit, i.e. per litre;
furthermore the water usage indicator will revolve. 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

BYPASSING THE WATER SOFTENER
Occasionally it may be necessary to put the unit
hydraulically in bypass, i.e. to isolate it from the water
distribution system; f.e.:
in case of an urgent technical problem with the water
softener;
when the water softener needs to be removed for
maintenance;
when it is not necessary to supply treated water to
the house/application (refill swimming pool,
irrigation,...).

WATER CONDITIONER SALT
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 conditioner salt. Therefore he should
periodically check the salt level inside the brine cabinet
and refill it if necessary. To open the salt lid, simply take it
by the handle and lift it. 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, resulting in a loss of softening capacity. A
higher level of water conditioner salt can cause salt
bridging (hard crust or salt bridges in the brine cabinet).
When you suspect salt bridging:
1. carefully pound on the outside of the brine cabinet to
break loose the salt bridges;
2. using a broom (or like blunt tool) carefully push the
salt to break it apart;
3. 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 in safe conditions to assure it 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'. As this is a time-
controlled water softener, it 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 (refer to section 'ELECTRONIC
CONTROL PANEL').
