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.
CONTROL VALVE
only for PF-SOF1
1. Make sure the O-ring in the riser insert and the tank O-
ring (around the threaded section of the control valve) are
in the correct position.
2. Screw the top distributor onto the control valve.
3. Lubricate the threaded section of the pressure tank, the
top of the riser tube and the tank O-ring of the control
valve; use a silicon-based lubricant.
4. Lower the control valve straight down onto the riser tube,
until the riser tube is correctly inserted in the riser insert;
then push it down firmly and screw it onto the pressure
tank.
