CONTENT CHECK
Actualpartsthatyouhave received,maydifferfromthe
pictures/illustrations in these Instructions!
Only on systems with ≥3 cuft of filter media: for ease of
transportation and installation, the filter media is NOT
loaded in the pressure tank, but delivered in separate bags
of 1 cuft; it must be loaded on-site, after positioning of the
pressuretank.
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 calledNormallyOpenService Valve
(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 allSimplexsystemswill be
open, guaranteeing uninterrupted supply of water.

DRAIN
We recommend the use of a stand pipe with air trap.
To prevent backflow from thesewerage system into the
appliance, always install and use an air gap (included with
PF-OXY1 & PF-OXY1+), 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 rateof the appliance.

ELECTRICAL
1. Connect the appliances power cord to the transformers
output.
2. Plug the transformer into an electrical outlet.
PRESSURIZING
1. Put the bypass system in 'bypass' position.
2. Make sure the electronic controller of the appliance is in
service mode.
3. Open the mains water supply.
4. Open a cold treated water faucet nearby the appliance
and let the water run for a few minutes until all air is
purged and all foreign material that may have resulted
from the installation is washed out; close the faucet.
5. Gently pressurizethe appliance, byputting it into service:
close the 'BYPASS' valve;
open the 'OUT' valve;
slowly open the 'IN' valve.
6. After 2-3 minutes, open a cold treated water faucet
nearby the appliance and let the water run for a few
minutesuntilallairispurgedfromtheinstallationandthe
filter media is rinsed (it is normal for the rinse water to
show some discoloration!); let the water run until the
rinse water is clear; close the faucet.
7. Check the appliance and all hydraulic connections for
leaks.
During the passage through the compressed air
chamber,the treated water will get highlyoxygenated. As a
consequence it may becomeslightly non-transparent (milky
appearance) when it flows from the tap into a glass. This is
totallyharmlessfor the qualityof thetreated water and will
disappear rapidly if thewater is left standing for a moment!
ELECTRONIC CONTROL PANEL
1. Program the electronic controller.
INITIATE A REGENERATION
We strongly recommend to postpone the execution of
this 'start-up' regeneration by 24 hours. The filter media
needs sufficient time to absorb water and reach its normal
service weight. If the regeneration is performed too soon,
the filter media may be pushed against the top distributor
duringthe backwash cycle, possiblyresulting in loss of filter
mediaor damageto the top distributor.
1. Manually initiate a regeneration, by pressing the scroll
button repeatedly until the display shows:
2. Leave the appliance in this position; the count-down
timer will count down to 0 sec and start a regeneration.

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.
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.

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.
