OPERATING CONDITIONS & REQUIREMENTS
Page 4
OPERATING PRESSURE MIN-MAX: 2,0-8,3 bar / 29-120 psi
check water pressure regularly; it may fluctuate severely
depending on the time of day, the day of the week or even the
season of the year.
take into account that night time water pressure may be
considerably higher than day time water pressure.
install a pressure reducer ahead of the appliance if necessary.
install a pressure booster, if it is likely that water pressure may
drop below the minimum.
OPERATING TEMPERATURE MIN-MAX: 2-48 °C / 36-120 °F
do not install the appliance in an environment where high
ambient temperatures (e.g. unvented boiler house) or freezing
temperatures can occur.
the appliance cannot be exposed to outdoor elements, such as
direct sunlight or atmospheric precipitation.
do not install the appliance too close to a water heater; keep at
least 3 m (10 ft) of piping between the outlet of the appliance
and the inlet of the water heater; water heaters can sometimes
transmit heat back down the cold pipe into the appliance;
always install a check valve at the outlet of the appliance.
ELECTRICAL CONNECTION:
the appliance only works on 24 VAC; 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 overcurrent protection.

INSTALLATION
Page 5
INLET & OUTLET
We strongly recommend the use of flexible hoses to
connect the appliance to the water distribution system; use
hoses with a large diameter in order to limit the pressure
loss.
If the appliance 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
appliance from the water distribution system in case of
repairs. It allows to turn off the water to the appliance, while
maintaining (untreated) water supply to the user.
WITH FACTORY BYPASS (optional)
Picture 1
= mains water supply (untreated water)
= inlet of appliance (untreated water)

1. Screw the factory bypass onto the in/out ports on the
control valve (&); make sure to install the gasket
seals. Tighten the nuts firmly by hand.
2. Screw the connection kit with nuts onto the factory
bypass (&); make sure to install the gasket seals.
Tighten the nuts firmly by hand.
3. Connect the mains water supply to the adaptor on the
inlet port of the factory bypass ().
4. Connect the house/application to the adaptor on the
outlet port of the factory bypass ().

2. Screw the connection kit with nuts onto the in/out ports
on the control valve (&); make sure to install the
gasket seals. Tighten the nuts firmly by hand.
3. Connect the 3-valve bypass system to the adaptors on the
in () and out () port of the control valve.
4. Connect the mains water supply to the inlet of the 3-valve
bypass system.
5. Connect the house/application to the outlet of the 3-valve
bypass system.
DRAIN
We recommend the use of a stand pipe with P-trap.
To prevent backflow from the sewerage system into the
appliance, always install and use the included drain adaptor
with air gap and double hose barb, to connect the drain hose
to the sewerage system.
Lay-out the drain hose in such a way that pressure loss
is minimized; avoid kinks and unnecessary elevations.
Make sure that the sewerage system is suitable for the
rinse water flow rate of the appliance.
Picture 3
1. Install the drain adaptor to the sewerage system; it fits
over a 32 mm pipe or inside a 40 mm pipe adaptor. Ensure
a permanent and watertight connection.
2. Connect a 13 mm hose to the drain connection of the
control valve (); secure it by means of a clamp.
3. Run the drain hose to the drain adaptor and connect it to
one of the hose barbs; secure it by means of a clamp. This
drain line operates under pressure, so it may be installed
higher than the appliance.

POWER-UP
After power-up the display will show the installed software
version for a period of 5 seconds.
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 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 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 remain in its
last position; when the power supply is re-established, the
control valve will return to the service position, stay there 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:
If powering off/on the appliance doesn’t solve this problem,
professional service is required.
MAINTENANCE REMINDER
Only available if the maintenance reminder function has
been activated and programmed by your supplier!
Once the maintenance interval is reached, the display will
intermittently show the message:
While the appliance will continue to operate normally, it is
recommended to have preventive maintenance performed
by a professional.
SERVICE MODE
In service mode the display shows the time of day and the

The regeneration cycle is necessary to wash out
impurities that are captured in the filter media during the
service cycle, and to prevent ‘caking’ of the filter media,
which may result in an increase of pressure drop over the
appliance. Typically a regeneration every 7 days should be
sufficient. In case of high flow rates, excessive water usage
or a high concentration of impurities in the incoming water,
it may be necessary to lower the number of days between
regenerations.

MAINTENANCE
Page 10
RECOMMENDATION
Notwithstanding the reliability of the appliance, we strongly
recommend to have it serviced and maintained on a regular
basis by a competent and duly trained technician. He will be
able to determine the appropriate maintenance interval for
the appliance, depending on your specific application and the
local operating conditions. The advantages of performing
regular maintenance are:
regular check of the local operating conditions (water
quality, pressure, etc);
regular control and adjustment of the settings of the
appliance, to guarantee it operates at maximum
efficiency;
minimize the risk of unexpected break-down.
Contact your dealer or installer for more information, or visit
our website.
ROUTINE CHECKS
Regularly the user should perform a basic check to verify if the
appliance is functioning correctly, on the basis of the
following control points:
1. Check settings of electronic control panel.
2. Check water composition before/after appliance.
3. Check drain line from control valve; there shouldn’t be
any water flow (unless appliance is in regeneration).
4. Check appliance and surrounding area; there shouldn’t be
any water leakages.
BYPASSING THE APPLIANCE
Occasionally it may be necessary to put the appliance
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,...).

SANITIZING THE APPLIANCE
This appliance is manufactured from premium quality
material and assembled in safe conditions to assure it is clean
and sanitary. If installed and serviced correctly, this appliance
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 appliance will automatically
rinse the filter media periodically.
If the power supply to the appliance is disconnected for a
longer period of time, we recommend, when the power
supply is re-established, to manually initiate a complete
regeneration.
