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
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.

4.4. 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:

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

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
