FC/D - FAC/D
1.Safety
1.1.General
The equipment has been designed and constructed according to D.P.R. n° 459 of 24th July 1996 (regulation for accomplishment of Norms 89/392/CEE, 91/368/CEE, 93/44/CEE and 93/68/CEE regarding the unification of States members laws in so far as machines are concerned).
It has been designed and constructed according to European Norms UNI EN 292-1, UNI EN 292-2, UNI EN 292-2/A1, UNI EN 983, CEI EN 60439-1, CEI EN 60 204-1.
Only authorized and skilled personnel will be allowed to carry out installation, start up as well as routine and planned maintenance.
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 properties. 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 § 3.5 page 6).
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, (see § 3.2 page 5) before connection. Do not make preliminary wiring connections.

FC/D - FAC/D
2.Principles of working
FC/D and FAC/D series filters 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 FC/D
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 working of the system is controlled by an automatic programmer, allowing to schedule the day and the hour of the regeneration (backwashing).
For the best working of the filter, the backwashing should be featured before the pressure drop reaches the threshold level (1 bar - 100 kPa). According to that, it is suggested to schedule the regeneration according to a pressure drop of 0.6÷0.7 bar (60÷70 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 FAC/D
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.
FAC/D 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.

AUTOMATIC FILTERS INSTRUCTIONS MANUAL
FC/D - FAC/D
Whether raw water contains organics and/or is biologically polluted, FAC/D 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 equipment allows to schedule the days (how often) and time of day for the regeneration, same way of quartz-sand filters, as above explained.
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.
