requirements. Refer to national/local laws and codes for correct recycling
of this appliance.
OPERATING CONDITIONS & REQUIREMENTS
Page 4
OPERATING PRESSURE MIN-MAX: 2,5-8,0 bar / 36-116 psi
low operating pressure may lead to insufficient backwash of the
filter media, resulting in an increase in pressure drop and/or a
reduction of the filtration capacity during the service cycle.
if installed on a well, verify that the well pump is powerful
enough to provide sufficient flow rate for the backwash cycle.
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: 4-48 °C / 39-120 °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:
this appliance only works on 24 VAC; always use it in
combination with the supplied transformer.
in case of damage to the power supply cable of the transformer,
immediately disconnect the transformer from the power outlet
and replace the 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.
ASSEMBLY
Page 5
CONTENT CHECK
Actual parts that you have received, may differ from the
pictures/illustrations in these Instructions!
For ease of transportation and installation, the filter
media may NOT loaded in the pressure tank, but delivered in
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).
During normal operation, the system delivers treated water.
As soon as it initiates a regeneration, it automatically goes
into bypass, guaranteeing uninterrupted supply of untreated
water.
It is possible to install a so called Normally Open Service Valve
(e.g. a solenoid operated diaphragm valve) in the outlet of the
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 installed in parallel;
- are programmed for different times of regeneration;
- may have a so 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 the control valve's standard 'untreated water
bypass during regeneration'.
During normal operation, all Simplex systems are in service,
doubling/tripling/… the service flow rate!
In case of a power failure, all Service Valves will be
deactivated, meaning the outlet of all Simplex systems will be
open, guaranteeing uninterrupted supply of water.
FILTER MEDIA LOADING
1. Move the pressure tank to the correct installation
location; position it on a flat and level surface. Make sure
to leave enough space for ease of service.
2. Position the riser assembly upright and centred in the
pressure tank; plug the top of the riser tube with a piece
of tape or clean rag, to prevent filter media from entering
the tube.
3. Place a funnel on the pressure tank opening and fill the
pressure tank with filter media; make sure the riser
assembly remains centered in the pressure tank.
4. Rinse the pressure tank opening to remove any grains of
filter media from the threaded section.
5. Unplug the top of the riser tube.
CONTROL VALVE

INSTALLATION
Page 6
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.
We strongly recommend the installation of a 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 full-flow (untreated) water supply to the user.

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 an air gap (drain adaptor
with air gap included with PF-GAC1 & PF-AG1), 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.
only for PF-GAC1 & PF-AG1

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.
only for PF-GAC1,5 & PF-AG1,5
Picture 7
1. Connect a pipe to the 1” BSP Male drain connection of the
control valve (); use an appropriate sealant.

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.

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.

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
application.

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.
