CONTENT CHECK
Actualpartsthatyouhave received,may differ from the
pictures/illustrations in these Instructions!
For ease of transportation and installation, the filter
media mayNOTloaded in thepressure tank,butdeliveredin
separate bags of 1 cuft; it must be loaded on-site, after
positioning of the pressure tank.
Check the content of the system, using the Composition
Overview in these Instructions. Identify and lay-out the
different components to facilitate the assembly.
SIMPLEX
Picture 1.a, 2.a, 3.a
A Simplex system consists of 1 single filter module (pressure
tank, filter media, control valve).
Duringnormaloperation,the system deliverstreatedwater.
As soon as it initiates a regeneration, it automatically goes
into bypass, guaranteeing uninterrupted supply of untreated
water.
It ispossibletoinstall aso calledNormallyOpenServiceValve
(e.g.asolenoidoperateddiaphragmvalve)intheoutletofthe
system, that is controlled by the electronic timer of the
system; this Service Valve will be activated during the entire
duration of the regeneration, to close-off the control valve's
standard 'untreated water bypass during regeneration'.
MULTIPLEX PARALLEL
Picture 4
A Multiplex PARALLEL system consists of 2 or more Simplex
systems, that:
-are hydraulically installedin parallel;
-are programmed for different times of regeneration;
-may have aso called Normally Open Service Valve (e.g. a
solenoid operated diaphragm valve) in the outlet of each
Simplex system, that is controlled by the electronic timer
of each Simplex system; this Service Valve will be
activated during the entire duration of the regeneration,
to close-off thecontrolvalve's standard 'untreated water
bypass during regeneration'.
During normal operation, all Simplex systemsare in service,
doubling/tripling/… the service flowrate!
In case of a power failure, all Service Valves will be
deactivated, meaningtheoutlet of all Simplexsystemswill be
open, guaranteeing uninterrupted supply of water.

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®duringan 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.

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
water filter. Typically a regeneration every 4 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.

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 yourspecificapplication andthe
local operating conditions. The advantages of performing
regularmaintenance 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, orvisit
our website.
ROUTINE CHECKS
Regularlytheusershouldperformabasicchecktoverifyifthe
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. Checkapplianceandsurroundingarea;thereshouldn’tbe
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
application.

SANITIZING THE APPLIANCE
This appliance is manufactured from premium quality
material and assembled in safeconditions to assureit is clean
and sanitary. If installed andserviced correctly,this appliance
willnotinfectorcontaminateyourwatersupply. 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.
