2. Principles of working
Softening is the process that allows to remove calcium and magnesium from water. These
two elements, together with bicarbonate, are the main cause of the scale inside thermal plant
and domestic appliances (heating system, laundry machines, etc.). They also can cause big
trouble in many industrial process.
The process of softening is featured by ion exchange. The resins contained in the column
exchange the ions calcium and magnesium (Ca++ and Mg++) against sodium ions (Na+), of which
they are charged. When the resins are exhausted, they are fully charged of calcium and
magnesium (Ca++ e Mg++) while they do not have any more sodium ions (Na+) available for
exchanging and they need to be regenerated.
Regeneration means re-built the charge of sodium ions (Na+) available from sodium chloride
(NaCl), common salt used in kitchen. During regeneration, an exchanging back is performed of
sodium ions (Na+) against ions calcium and magnesium (Ca++ e Mg++) which are carried away
to drain. The equipment prepares automatically the brine from the salt (NaCl) in grain or tablets.
AM series softeners are used for water treatment for residential and industrial applications as
well. All the materials, resins included, are food grade and approved for drinking water.
The range of models includes systems with capacity from 5 up to 60 m³/h and capacity from
900 up to 7200 m³ x ºF.
The working of the system is controlled by an automatic programmer, allowing to schedule
the frequency and the hour for the regeneration. Then the system automatically starts the
regeneration that proceed automatically. During regeneration, (except for "fast rinse" phase) the
system supplies non softened water thanks to a by-pass inside the automatic valve; for
AM/METER models, water supply during regeneration is completely inhibited by means of a
membrane valve mounted on the outlet.
These system can be equipped with automatic sterilizing device (Nobel CL 90 or CL 180),
according to the local laws of some countries for the treatment of drinking water.

4.2. How to remove packaging
The vessels are shipped wrapped in a plastic foil; remove it with care before starting-up. The
automatic valves and pulse sender water meter (if present) are packed in a wooden crate.
Withdraw carefully the components from the crate. The resins are shipped in bags of 25 l each,
and the quartz-sand in bag of 50 kg or fraction of it. Keep the cards and everything contained
inside the packaging.
4.3. 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.
Figure A
4.4. Placing & commissioning
•Place the column of resins and the brine tank on a perfectly flat surface. Their mutual
position is shown on the installation drawing. The shown scheme is only suggested; the
column can be placed in different positions; according to the inlet/outlet connections on the
valve group.
•Load the supplied quartz-sand 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 tightening the
nuts.
•Load the supplied resins into the vessel, through the upper man-hole (or through the upper
head, see components drawing). The resins are shipped separately; check that the shipped
and available quantity complies exactly with the quantity listed in the Weight Table § 3.5
page 6).
•After completed the loading, close the upper man-hole (or upper head)
•Fix the group of the regeneration valve to the resins vessel. The valves group includes also
the programmer.
•For models AM/R METER, AM2700/METER and AM3300/METER :connect the pre-
assembled piece fitting/membrane valve on the outlet connection of the regeneration valve.
NB :
The fittings of control valve type S240 have to be inserted just pushing them inside the
connections of body valve and then fixed with proper pins. The fittings of valves type S360
are flanged type with 4 fixing bolts.

4.5. Hydraulic connections
(see installation and components drawings)
In order to avoid shut-off during maintenance operations, an emergency by-pass line
should be provided
•Connection of inlet fittings
For models AM/R, AM2700 and AM3300 only:complete the line from the untreated water line
to the outlet fitting of the regeneration valve.
For all other AM models:complete the line from the untreated water line to the outlet fitting of
the regeneration valve; connect also the inlet membrane valve V2 to the same water line.
•Connection of outlet fittings :
SERIES /T and /V, models AM/R, AM2700 and AM3300 only:complete the line of the treated
water line to the inlet fitting of the regeneration valve.
SERIES /T and /V, all other AM models:complete the line of the treated water line to the inlet
fitting of the regeneration valve; connect also the outlet membrane valve V1 to the same
water line.
SERIES METER: complete the line of the treated water line to the outlet membrane valve V1.
For models AM/R, AM2700 and AM3300 only the outlet membrane valve is installed
immediately downstream of the outlet fitting of the regeneration valve.
For all other AM models the outlet membrane valve is plumbed at the bottom side of the resins
columns and the outlet fitting of regeneration line is plugged.
•Insert horizontally the pulse sender water meter downstream of outlet connections, (only for
series AM/V, AM/RV, AM/METER and AM/R METER).
•Connect the drain fitting placed on the side of the automatic valve to a floor drain. The gate
valve mounted on the drain fitting will be used to adjust the backwash flow rate.
A common flexible pipe made in plastic or rubber can be used for the drain line downstream
of the gate valve; its size must be equal or larger of the one mentioned on
“CHARACTERISTICS FOR EACH MODEL” table.
It is suggested that the drain line could be inspected in order to check quantity and quality of
drain water, as well as any leakage of resins from the unit.
CAUTION : Do not run the drain line together with overflow line of the brine tank; it will cause
the filling of the brine tank.
•Connect the over-flow fitting of the brine tank to a floor drain, with a line separated from the
drain lines of the vessels. Use proper sized flexible plastic or PVC pipe.
•Complete the line from the brine drawing fitting (on the side of the automatic valve) to the
float valve of the brine tank. For models up to AM 2100, use for the connection the supplied
plastic tubing ø 9.5 (mm); for models AM 2700 and over use ¾" galvanized pipe, or proper
sized PVC or plastic tubing, suitable to withstand the pressure and depressure (0.5 bar
negative).
•run the plastic tubes, already connected to the electronic programmer, to the fittings placed
on the control valves and on the diaphragm valves, according to the numbered sketch.
CAUTION : to avoid any damage of the plastic fittings and parts, it is required to hold all the
piping using adequately sized brackets.
4.6. Electrical wiring connections
•Connect the power feeder of the programmer to a power socket; check that the available
power is correct as listed in technical characteristics (see § 3.2 page 5).
•Connect the DIN plug from the water meter on the socket placed on the side of the
electronic programmer (only for series AM/V, AM/RV, AM/METER and AM/R METER).

5. End cycle and regeneration
5.1. End cycle
The softeners are equipped with an electronic programmer that allows to schedule the
automatic regeneration. The automatic start of regeneration depends on the type of
programmer that equips the unit, as follows :
•AM/T and AM/RT SERIES : electronic time programmer : selected time and day (24 h, 14
days, max 1 regeneration per day)
•AM/V and AM/RV SERIES : end-cycle by time/volume (pulse sender external to the
automatic valve); regeneration runs at selected time and day
(24 h, 14 gg, max 1 regeneration per day), or after the preset
volume of water has been supplied but only at a pre-set time.
•AM/METER and
AM/RMETER SERIES :
end-cycle by volume; regeneration runs after the preset
volume of water has been supplied, with membrane valve to
shut off the flow during regeneration
The end-cycle has to be adjusted according to the quality of available water and the
consumption of water.
The max. quantity of available soft water the equipment can supply between two following
regeneration is to be calculated as follows:
=
where 1°Fr = 10 ppm CaCO3= 0.56° German
The cycle of all NOBEL softeners are expressed by the number identifying the model (i.e.
AM 2700/D, the cycle is 2700 m3x °Fr)
The regeneration can also be started manually at any time (see instruction of the
programmer).
5.2. How to select the end-cycle
The programmer installed on the AS/V and AS/METER series allows also working mode time
only, besides volume only and time/volume modes.
Whether it is desired to use the equipment with working mode different than the standard
one, it is possible to select an end-cycle mode different than the pre-set one; it is required to
select the new mode, according to the explanation in the special instruction of the programmer
(mod. AQUA TIMER).

5.3. Regeneration
The regeneration phases run one after one, as follows :
1. backwashing: during this phase, the water flush from the bottom to the top of the column,
lifting the resins which are mixed together and release the solids trapped on surfaces of
the resins bed 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. During this phase, it is very important to check that there is no
leakage of resins to the drain.
2. brine drawing: during this phase, a concentrated solution of water and sodium chloride
(common kitchen salt, in grain or, better, tablet) is drawn from the brine tank to the resins
column, by an injector. The brine crosses through the column from the top to the bottom.
3. slow rinse: it is the first step of the rinse, during which the ion exchanges between
sodium chloride and resins is featured. The time of this phase is not adjusted, since it
starts when the brine tank is completely empty (all brine has been drawn); a special
device built-in the brine float valve avoids the air drawing.
4. fast rinse: it is the phase during which the residual of salt is flushed away through the
resins; at the end of this phase the resins column is ready to start again a new service
cycle.
NOTE: During the fast rinse phase the unit supplies the water to the brine tank, in order to
prepare the brine for the following regeneration. The brine tank refill will be
automatically completed when the level mark of water reaches the float valve inside
the tank.
NOTE : During regeneration, (except for "fast rinse" phase) the system supplies non
softened water thanks to a by-pass inside the automatic valve; for AM/METER and
AM/RMETER series, water supply during regeneration is completely inhibited by
means of a membrane valve mounted on the outlet.
See programmer manual for the time of each phase of regeneration.

6. Starting-up
The starting-up of the unit consists of running a first regeneration cycle, during which the
columns of resins and brine tank will be filled of water, all automatic features will be checked
and the unit will be prepared to start the service.
During the starting-up is not required that salt is available inside the brine tank.
At the end of the first regeneration, put the salt into the brine tank (it can also be completely
filled). Take care not to put salt inside the protection pipe.
See § 7 page 12 for recommended quality of salt to be used.
To start-up the unit, proceed as follows :
•Be sure that the control panel is switched OFF.
•Open the by-pass valve, keeping closed the shut-off valves upstream and downstream of the
system.
•Close only partially the gate valve on backwash drain line.
•Turn clockwise the cam shaft located on the back of the programmer, until the first piston is
pressed. The second piston must not be pressed (BACKWASH).
•Open slowly and not completely the inlet valve. Water will enter from the bottom of one of the
column as air will be expelled from the top to the drain.
•When only water will come out from the drain, open completely the inlet valve and open
slowly and gradually the backwash gate valve. The flow rate must be the highest allowable
without any leakage of resins through the drain line; so adjust the gate valve accordingly.
•When the proper flow rate of backwash has been stated, adjust the gate valve definitely.
•The backwashing phase must run until the water coming out the drain is perfectly clear.
•Using a pail, add water in the brine tank, until the water mark is approx. 30 cm (12 inches)
from the bottom (this is required for the initial regeneration only and is automatically filled
thereafter).
•Turn again clockwise the cam shaft, until both pistons are pressed (BRINE DRAWING AND
RINSE). Check that some water flows to the drain line, while, in the same time, the water
flows from the brine tank to the unit. Check the water mark diminution in the brine tank
(BRINE DRAWING).
•Turn again clockwise the cam shaft, until only the second piston is pressed. The first piston
must not be pressed (FAST RINSE). The water flows to the drain line; allow the water flowing
until the drain water looks perfectly clear. In the same time the water flows to the brine tank,
too, in order to prepare the brine for the following regeneration cycle. The water level inside
the brine tank is automatically adjusted according to the float valve.
•Turn clockwise the cam shaft, until both pistons are released and not pressed (SERVICE).
The 3rd piston, available only for some kind of programmers, is used only to control
hydraulically the working of the inlet and outlet diaphragm valves of the column (if available); it
must be ignored.
•Switch ON the control panel.
•open the outlet valve and close the by-pass valve
•Put the salt into the brine tank (it can also be completely filled). Take care not to put salt
inside the protection pipe.
Starting now the unit is on service and feeds treated water.

7. Service & maintenance
Softeners are equipment designed to treat raw water supplied from municipalities or
from well.
ANY OTHER APPLICATIONS OF THE EQUIPMENT DIFFERENT THAN THE MENTIONED
ONES IS MADE UNDER THE ONLY RESPONSIBILITY OF THE USER.
The correct handling of the equipment requires:
•take off the raw water suspended solids, if any, by an adequate filtration.
•check that the water pressure is within the stated values.
•check the salt level in the brine tank. A salt lack will cause the incomplete regeneration of
the resins, or not any regeneration at all; in that case the supplied water will not be
treated (softened).
It is suggested to use clean salt, better in the shape of tablets, available almost everywhere,
in order to avoid residuals of sand or dirties in the tank and along the brine lines.
Not any further special maintenance operations are required.
The only consumption material is salt.
The average life of the ion exchange resins is approx. 5÷8 years, according to the quality of
raw water and how often regeneration is featured.
7.1. Disposal
In case of disposal of the unit or parts of it, it must be made according to local laws
concerning the waste of the materials. It should be taken in consideration that resins are usually
listed as plastic materials and not as toxic or harmful material (the safety bulletin of resins are
available upon request).
