1.2. How to displace the unit
Particular care and attention should be put in during moving and displacing of heavy items, in
order to avoid injuries to persons or damage (see § 3.5 pag. 7). The heavy parts must be lifted
and displaced always hooking and lifting them by the points shown on the drawings (see fig. 1)
and using only suitable ropes, hooks and/or chains, according to the weight (see weight table).
1.3. Hydraulics
All operations must be performed by and/or under direct supervision of skilled and authorized
operators, using proper tools and personal protection devices if required (CE marked).
Before any operation of taking out pipes or part of hydraulic system, it is required to release
the pressure inside and empty the part of the system.
1.4. Electrical
Before starting any operation on electrical devices, be sure that main power supply is OFF.
All operations must be performed by skilled and authorized operators.
In case of liquid leakage, switch off the main power supply before operate. Before the
switching ON, be sure all the parts of the system are perfectly dry. Check that the available
electrical power is correct before connection. Do not make preliminary wiring connections.

2. PRINCIPLES OF WORKING
FCD, FACD and FCD series filters (on versio DT, DT-DUAL, DP and DP-DUAL) are used for
water treatment for residential and industrial applications as well. All the materials are food
grade and approved for drinking water.
2.1. Quartz-sand filters FCD
The filtration through a sand media is a mechanical process that allows to remove suspended solids
(even of small dimensions) from water.
The slower is the linear flow (speed of water trough the filtering bed), the better is the filtration action.
During the process, as the filtering bed traps the suspended particles, as filtration action increases,
since the trapped solids works the same way of a filtering bed!
But it also increases the resistance of the filtering bed against the water flow; so the pressure drop
between inlet and outlet increases as well.
The maximum allowed pressure drop is 1 bar (100 kPa), after that it is required to backwash the
filtering bed.
The purpose of the backwashing is to re-built the filtering bed efficiency, by removing the solids
trapped during service; it is featured by a counter-flow of water through the filtering bed.
The programmer allows to set the regeneration at the scheduled days and time; for DP and DP-DUAL
models, regeneration can also be set to start when the max allowable value of pressure drop is reached.
For the best working of the filter, the backwashing must be featured before the pressure drop
reaches the threshold level (1 bar - 100 kPa).
During regeneration the water supplying is completely inhibited by means of a membrane valve
mounted on the outlet line.
2.2. Activated-carbon filters FACD
Filtration through a bed of activated carbon is the process that allows to remove organic matters and
chlorine from water.
The lower is the flow rate, the better is the filtration action.
FACD series filters are designed and sized for chlorine removal. The expected life of activated-carbon
used as de-chlorination (chlorine removal) is very long; it works as chemical reduction of chlorine to
chloride ion.
Activated carbon action is not selective in removing the substances contained in water and crossing
the filtering bed: hence, it removes also the organics the water contains, if any.
Therefore, it could happen that the filtering bed is exhausted or clogged by the trapping of substances
contained in water, even if the purpose of treatment was not the removal of these substances, but just the
de-chlorination.
Furthermore, it could happen that the filtering bed releases some of the substances previously trapped
in higher concentration than before.
Since it is quite impossible to forecast the exhaustion of the activated carbon bed, or to monitor the
exhaustion itself, with current instrumentation, the utilization of an activated carbon filter must be strictly
avoided without adequate pre-treatments, like quartz-sand filtration, chlorination, etc.
Whether raw water contains organics and/or is biologically polluted, FACD series filters CANNOT be
used without written authorization by NOBEL Technical Department.
The activated-carbon bed also works as a mechanic filter same way of quartz-sand bed.
Although this working should be avoided, it can happen that the pressure drop of activated-carbon bed
reaches a value of 1 bar (100 kPa); in this case the backwashing of the filtering bed is required.
The programmer allows to set the regeneration at the scheduled days and time; for DP and DP-DUAL
models, regeneration can also be set to start when the max allowable value of pressure drop is reached.
For the best working of the filter, the backwashing must be featured before the pressure drop
reaches the threshold level (1 bar - 100 kPa).
It is recommended to run the regeneration only when it is strictly required: the backwashing causes
the mixing of the bed and could displace the higher layers of activated carbon (most polluted) from the
top to the bottom of the column.
During regeneration the water supplying is completely inhibited by means of a membrane valve
mounted on the outlet line.

2.3. Iron removal filters FFD
Iron removal filters series FFD are used for water treatment for residential and industrial
applications as well. All the materials, media filter included, are food grade and approved for
drinking water. The range of models includes systems with capacity from 4.0 up to 40.0 m³/h.
Iron removing is the process of filtration that allows to remove iron and manganese from
water. This special filtration is made through a special catalytic media filter, (activated
pyrolusite, briefly successively named PL, mixed with quartz-sand) which action is to oxide and
then filter the dissolved iron and manganese.
The media filter is kept in its activated state by mean of an oxiding agent, oxigen or
hypochlorite, contained in water.
As a general rule, the continuous addiction of sodium hypochlorite in water, upstream of the
filter, is used; this system is more reliable and effective than the forced oxygenation.
Under the same conditions of the filtering bed, the filtration action increases when the linear
flow (speed of water trough the media) decreases, hence at a lower flow rates.
The slower is the linear flow, the better is the filtration action.
During the process, as the filtering bed traps the suspended particles, as filtration action
increases, since the trapped solids works the same way of a filtering bed !
But it also increases the resistance of the filtering bed against the water flow; so the pressure
drop between inlet and outlet increases as well.
The maximum allowed pressure drop is 1 bar (100 kPa), afterthat it is required to backwash
the filtering bed.
The purpose of the backwashing is to re-built the filtering bed efficiency, by removing the
solids trapped during service; it is featured by a counter-flow of water through the filtering bed.
The programmer allows to set the regeneration at the scheduled days and time; for DP and
DP-DUAL models, regeneration can also be set to start when the max allowable value of
pressure drop is reached.
For the best working of the filter, the backwashing must be featured before the pressure drop
reaches the threshold level (1 bar - 100 kPa).
During regeneration the water supplying is completely inhibited by means of a membrane
valve mounted on the outlet line.

4. INSTALLATION
4.1. How to remove packaging
The vessels are shipped wrapped in a plastic foil; remove it with care before starting-up.
Keep the cards and everything contained inside the packaging.
The media filter are shipped as separated:
•in bags of 25 kg (35 liters approx) each or fraction anthracite
•in bags of 25 kg each or fraction quartz sand
•in bags of 25 kg (50 liters approx) each or fraction activated carbon
•in bags of 25 kg each or fraction PL
4.2. How to move and lift the unit
The vessels can be displaced when they are empty, hooking and lifting by the special rings
mounted on the upper part of the vessels (see fig. 1). It is recommended to use proper sized
hooks and ropes, according to the weight. It is also possible to hook and lift the vessel by the
bearing legs.
4.3. Placing & commissioning
Place the unit according to the available room of the site and the required room for current
maintenance and service of the equipment. See the dimensional drawing.
•Place the column of media filter on a perfectly flat surface. See the dimensional drawing
concerning the placing of the unit according to the walls of the site and required room for
maintenance and service. The shown scheme is only suggested; the column can be placed
in different positions; according to the inlet/outlet connections on the valve groups.
•Fix the valves manifold to the vessel (see installation drawing)
•Fix the control board to the valves manifold
-DUAL arrangements only :
•Repeat the same operations for both columns; yet, the control panel is only one for both
columns and must be fixed on column A (see installation drawing).

4.4. Hydraulic connections (see DRAWINGS installation and components)
In order to avoid shut-off during maintenance operations, an emergency by-pass line
should be provided
•Complete the line from inlet fittings to the raw water line.
•Complete the line from outlet fittings (valve V2) to the treated water line.
•Connect the drain valves (V1 and V5) to a floor drain. The gate valve mounted downstream
of the valve V5 will be used to adjust the backwash flow rate.
A common pipe can be used for the drain line; its diameter must be of at least one size larger
of the one mentioned on “CHARACTERISTICS FOR EACH MODEL” table.
It is suggested the drain line could be inspected in order to check quantity and quality of
drain water, as well as any leakage of media filter from the unit.
•Connect the inlet air fitting, placed on the base manifold of the solenoid valves, to a
compressed air-mains, complete with pressure reducer, dehumidifier filter and shut-off valve.
The air pressure must be kept at value equal or higher of the pressure of water to be treated,
with max value of 8.0 bar.
•Whether water is used to pilot the valves, the inlet fitting of the base manifold of the solenoid
valves must be connected to the pilot water fitting (¼"), pre-arranged on the inlet manifold of
the column; run to the drain a pipe from the drain fitting (¼") of the base manifold of the
solenoid valves.
•Complete the line between the outlet fitting of each solenoid valve to the correspondent
membrane valve:
SOLENOID VALVE MEMBRANE VALVES
Solenoid
v. no.
TYPE no. TYPE
1 NC V1 NC
2 NC V2 NA
3 NC V3-V4-V5 NC-NA-NC
All the solenoid valves can be hand-driven by the lever placed at the base of each of them; the
turning of the lever simulate the action of the coil. Then, for valves NC type, the valve is closed
when the lever is on parallel to the base; it is opened when the lever is on perpendicular to the
base itself.
-DUAL arrangements only :
•the hydraulic connections must be made for both columns
•each group of pilot solenoid valves (E1A-E2A-E3A / E1B-E2B-E3B) is coupled to its own
filtering columns (A/B)
•put in the 2 pressure sensors on the inlet and outlet manifolds of the 2 columns (see
transducers drawing)

4.5. How to load the media filter
The media filter must be loaded inside the vessel afterthat the placing of the filter is
completed or in the case the media have to be replaced.
•Open both the side man-holes
•Check that the filter nozzles are correctly fixed and not damaged.
•Load the supplied quartz-sand (2-3 mm size for FCD and FFD filters, 1-2 mm size for FACD
filters) into the vessel, through the lower man-hole, until the sand covers completely the filter-
nozzles. Make a flat surface of the sand using a wooden tool, in order to avoid any damage
to the coating of the vessel.
•Close the man-hole, after checking the integrity and correct position of the gasket, by
tightening the nuts.
•Load the rest of supplied media filter into the vessel, through the upper man-hole (or through
the upper head, see components drawing). The media filter are shipped separately; check
that the shipped and available quantity complies exactly with the quantity listed in the Weight
Table (see § 3.5 pag. 7).
Filtering media must be loaded, one after the other one, and according to the following order:
◊quartz sand 2÷3 mm (only for filters FCD and FFD)
◊quartz sand 1÷2 mm (only for filters FCD and FACD)
◊quartz sand 0.4÷0.7 mm (only for filters FCD)
◊anthracite (only for filters FCD)
◊activated carbon (only for filters FACD)
Take care to make a flat surface of each layer of sand, before load the next one.
(For FFD filters only : after loaded the quartz sand 2÷3 mm, load 3 bags of quartz sand
0.8÷2 mm and 2 bags of PL, alternately (one bag of quartz-sand then one of PL, and so on).
NB: The alternating loading is required in order to mix the two kind of media (quartz-
sand 0.8÷1.2 and PL) supplied; the mixing will be properly completed by featuring
the first backwashing .
•After completed the loading, close the upper man-hole (or upper head), after checking the
integrity and correct position of the gasket, by tightening the nuts

5. END CYCLE AND REGENERATION
5.1. End cycle at time (for all version)
The electronic micro-processor programmer allows to run the regeneration according to time
schedule, at pre-set time and day (max 3 regeneration per day).
5.2. End cycle at pressure drop (only for version DP e DP-DUAL)
The unit is equipped with 2 pressure sensors plumbed on inlet and outlet line of the filters;
the sensors gauge the correspondent pressure (IN/OUT) and therefore also the differential
pressure; when the pressure drop across the filtering bed reaches the value of 0.8 bar (80 kPa),
the end-cycle is driven.
During normal service, possible peaks of pressure could cause a wrong indication of reached
max allowable pressure drop; in order to avoid that, the end-cycle driving is delayed of an
adjustable time. Hence the max pressure drop must remain for all the time of adjusted delay, to
drive the end-cycle.
To set the regeneration by time only (regardless of pressure drop), proceed as follows :
-set at least 1 regeneration by time schedule
-enter as max allowable pressure drop (end-cycle) the value 10000.
To set the regeneration by pressure drop only (regardless of time), proceed as follows :
-delete any programmed regeneration by time control
-enter as max allowable pressure drop (end-cycle) the desired value (standard =8)
5.3. Regeneration
The regeneration is automatically controlled by the electronic programmer according to time
schedule or (only for version DP e DP-DUAL) pressure drop.
The regeneration can also be started manually at any time, out of any automatic
programme, by keeping pushed for 3 consecutive seconds the button “START”.
Warning : •The pushing of the button "START", while a regeneration is already
running, does not have any effect.
•An undesirable regeneration can be interrupted, in any moment, by
keeping pushed the button “RESET” for 3 consecutive seconds.
When the manually started regeneration is completed, the unit will continue to work
according to previous programming.
-DUAL arrangements only :
The regeneration of column A starts when the button “START” is kept pushed for 3 consecutive
seconds, while the column B turns on REGENERATION REQUIRED.
The regeneration of column B can be started, before the one of column A is completed,
interrupting this one by keeping pushed for 3 consecutive seconds the button “RESET”.


The regeneration can also run in case of power failure, by hand-driving the lever of the pilot
solenoid valves: the solenoid valve is closed when the lever is on parallel to the base and it is
open when it is on perpendicular to the base itself. Naturally, the compressed air supplying (air
controlled valves) or pilot water supplying (water controlled valves) must be assured.
The correspondent membrane valves (controlled by the pilot solenoid ones), if NC type is
open when the solenoid valve is open, and viceversa if the membrane valve is NO type.
PHASE SOLENOID VALVES
EXCITED (=OPEN)
OPEN VALVES
SERVICE // V2 - V4
BACKWASHING E2 - E3 V3 - V5
RINSE E1 - E2 V1 - V4
The regeneration phases run one after another, as follows :
1. Backwash : during this phase, the water flushes from the bottom to the top of the column,
lifting the filtering media and releasing the solids trapped on its surface during the service.
The backwashing water flows to drain from the top of the column. This is the only phase,
during which the water crosses through the column from the bottom to the top.
2. Rinse : it is the phase during which the filtering media are rinsed; at the end of this phase
the column is ready to start again a new service cycle.
NOTE: During regeneration the water supplying is completely inhibited.
NOTE : For -DUAL arrangements, when regeneration is required, column A starts it
immediately, while in the same time column B enters in “regeneration
required”state, although it continues to feed water.
At the end of regeneration of column A, with an adjustable delay (see
following how to adjust time of delay), column B starts regeneration.
5.4. Inhibit of the regeneration
It is possibile to inhibit the automatic starting of regeneration by mean of an external contact,
using the input I2 of the programmer as described at paragraph "Electrical wiring connection".
Hence, when the end-cycle is reached, the filter will remain on REGENERATION
REQUIRED until the inhibit signal is switched off.
Even if the inhibit signal is still on, it is also possible to start manually the regeneration, as
above explained.
5.5. Inhibition of the water supply
It is possibile to inhibit the water supply during the service by mean of an external contact,
using the input I6 of the programmer as described at paragraph "Electrical wiring connection".
Hence the filter will not be able to supply water until the inhibit signal is switched off.

8. STARTING-UP
The starting-up of the unit consists of running a first regeneration cycle, during which the
filtering media column will be filled of water, all automatic features will be checked and the unit
will be prepared to start the service.
At the beginning, it is suggested to operate manually, and to hand-driven the valves, by
hand-driving the lever of the pilot solenoid valves:
the solenoid valve is closed when the lever is on parallel to the base and it is open
when it is on perpendicular to the base itself.
This way will allow to stop, to run for longer time or to repeat each phase as desired, and to
adjust the flow rates according to the attached table.
To start-up the unit, proceed as follows (for -DUAL arrangements, operate on column A
only):
•DISCONNECT ELECTRIC POWER
•shut off the inlet, outlet and by-pass gate valves.
•close quite completely the gate valve along the backwash drain line
•hand-drive the solenoid valves E3 to open the backwashing membrane valves
•open slowly and only partially the gate valve on inlet line. The water will enter inside the
vessel from the bottom and, during filling, will expel the air inside it.
•when only water will come out from the drain, open completely the inlet gate valve and adjust
the backwash drain gate valve in order that the flow rate will be the highest allowable without
any leakage of media filter through the drain line; when the proper flow rate of backwash has
been stated, adjust the gate valve definitely. The backwashing phase must run until all the
water coming out the drain is perfectly clear.
•Hand-drive the solenoid valves E3 to close the backwashing membrane valves.
•Hand-drive the solenoid valve E1 to open the membrane valve V1 (RINSE); the rinse phase
must run until all the water coming out the drain is perfectly clear.
•Hand-drive the solenoid valves E1 to close the valve V1 and to conclude the regeneration.
•Switch ON the control panel.
•Open the outlet valve .
Starting now the unit is on service and feeds treated water.
For -DUAL arrangements : repeat all listed operation on column B
It is suggested to check, during the running of the first automatic regenerations, that the
adjusted flow rates and times are correct.

9. SERVICE & MAINTENANCE
Normally, these units do not require any regular maintenance operation and there is not any
consumption material to be currently replaced.
The only parts that can be aged are the electrical components and moving parts, as listed :
•the membrane of the automatic valves; after years, they can be aged and crack.
•the solenoid valves can break down (electric) or can get dirty if the pilot fluid is not
perfectly clean.
•The average life of the media filter is approx 5÷8 years, according to the chemical-phisical
characteristics of the water and how often the regeneration is featured.
The correct handling of the equipment requires :
•check monthly the values of pressure and flow rate of water, which have to comply with
stated ones.
•check that the air and/or water pressure are within the stated values.
•check that the values of pressure shown by the programmer meet the ones gauged by the
manometers (only for DP and DP-DUAL arrangement).
Not any further special maintenance operations are required.
Not any consumption material is required .
9.1. Media filter, nozzles
Whether the filtering bed is clogged and “packed” in order that it is impossible to backwash it
properly, the replacing of the media filter is required.
Proceed as follows for the emptying :
•Switch OFF the control panel
•Close the shut-off valves upstream and downstream of .
•Empty the column of water, by opening the bottom drain valve
•Open the upper-side man-hole (or upper head)
•Open the lower-side man-hole, leaving one nut inserted in. It will allow to control the flow
of the media filter outside.
•Then open completely the lower and side man-hole. Keep the nuts and gaskets of the
man-holes.
•Flush water to take out the media filter still laying along the internal walls of the column
and on the internal nozzles.
•Complete the emptying of the column, using an aspirator, if necessary.
•During the last part of the operation, take care not to damage the nozzles mounted on the
holding plate.
•Replace the damaged nozzles, if any.
Proceed as explained at § 4.5 to load the new media filter.
Proceed as explained at § 8 to start-up the unit, after replacing of media filter.
