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 softening
resin is NOT loaded in the pressure tank, but delivered in
separate bags of 25 ltr; 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
(PF-SOF1-SIM & PF-SOF1,5-SIM)
A Simplex system consists of 1 single softening module
(pressure tank, resin, control valve and accessories).
During normal operation, the Simplex system delivers
softened water. As soon as it initiates a regeneration, it
automatically goes into hard water bypass, guaranteeing
uninterrupted supply of untreated water
It is possible to upgrade a Simplex system to a Duplex Parallel
system, by adding a second Simplex system.
DUPLEX ALTERNATING
(PF-SOF1-ALT & PF-SOF1,5-ALT)
A Duplex ALTERNATING system consists of 2 Simplex systems,
that:
-are hydraulically installed in parallel;
-are electronically interconnected by means of an
InterConnect cable;
-have a Normally Closed solenoid operated diaphragm
valve (so called Service Valve) in the outlet of each
Simplex system; this Service Valve is controlled by the
electronic timer of the Simplex system and is activated
during the service cycle to open the outlet of the
respective Simplex system;
-share 1 brine tank, that contains 2 brine valves.
During normal operation, only 1 of the 2 Simplex systems is
in service, while the other one is regenerating or ‘in
standby’!As soon as the first Simplex system initiates a
regeneration, the second system goes into service,
guaranteeing uninterrupted supply of treated water. In case
of a power failure, both Service Valves will be deactivated,
meaning the outlet of both Simplex systems will be closed off,
cutting off the water supply (potentially hard water!) to the
application.
DUPLEX PARALLEL
(PF-SOF1-PRL & PF-SOF1,5-PRL)
A Duplex PARALLEL system consists of 2 Simplex systems,
that:
-are hydraulically installed in parallel;
-are electronically interconnected by means of an
InterConnect cable;
-have a Normally Open solenoid operated diaphragm valve
(so called Service Valve) in the outlet of each Simplex
system; this Service Valve is controlled by the electronic
timer of the Simplex system and is activated during the
entire duration of the regeneration, to close-off the
control valve's standard 'hard water bypass during
regeneration';
-share 1 brine tank, that contains 2 brine valves.
During normal operation, both Simplex systems are in
service, doubling the service flow rate! When one of the
Simplex systems initiates a regeneration, it immediately
communicates it's status to the other Simplex system via the
InterConnect cable, to make sure the other Simplex system
remains in service, guaranteeing uninterrupted supply of
treated water. In case of a power failure, both Service Valves
will be deactivated, meaning the outlet of both Simplex
systems will be open, guaranteeing uninterrupted supply of
water.
For correct assembly, repeat the different assembly steps,
until both Simplex systems are assembled and positioned
correctly.
For large installations, with an important need for treated
water, 2 or more Duplex systems can easily be installed in
parallel hydraulically, to double/triple/... the flow rate and
softening capacity.
RESIN 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 resin from entering the
tube.
3. Add water to the pressure tank to a height of ±30 cm from
the bottom; this water will protect the bottom of the
pressure tank and the bottom distributor, during filling of
the pressure tank.
4. Place a funnel on the pressure tank opening and fill the
pressure tank with resin; make sure the riser assembly
remains centered in the pressure tank.
5. Rinse the pressure tank opening to remove any resin
beads from the threaded section.
6. Unplug the top of the riser tube.

MAINTENANCE
Page 16
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. Measure water hardness before/after appliance.
3. Check drain line from control valve; there shouldn’t be
any water flow (unless appliance is in regeneration).
4. Check drain line from brine tank overflow; there shouldn’t
be any water flow.
5. 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.

WATER CONDITIONER SALT
This appliance needs 'brine' for its periodic regenerations.
This brine solution is made from water, that is automatically
dosed in the brine tank by the control valve, and water
conditioner salt. The user should make sure that the brine
tank is always kept full of water conditioner salt. Therefore he
should periodically check the salt level inside the brine tank
and refill it if necessary. Simply lift the brine tank cover to
check the salt level inside the brine tank.
Ideally the level of water conditioner salt inside the brine tank
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 tank). When you suspect salt bridging:
carefully pound on the outside of the brine tank to break
loose the salt bridges;
using a broom (or like blunt tool) carefully push the salt to
break it apart;
pour warm water over the top of the salt to dissolve it.
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 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 is equipped with a
'days override' feature, that will automatically rinse the resin
bed periodically, even in case of low or absence of water
usage.
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.
NORMALLY CLOSED SERVICE VALVES
(only for PF-SOF1-ALT & PF-SOF1,5-ALT)
Picture 16
= automatically operated = normally closed
= manually operated = constantly open
The Normally Closed Service Valve in the outlet of each
Simplex system will only be opened when it is powered. To
manually open the Normally Closed Service Valve (f.e. in case
of a power failure), simply turn the white solenoid coil
counter clockwise.
