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 7).
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

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/DT, AM/DV and AM/D METER 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, the system supplies non softened
water thanks to an internal by-pass; 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.

Installation
4.1.
Room conditions
In cold countries, whether the room temperature is below 15 °C (59°F), the salt requires
longer time to be dissolved, even up to 10 hours; this feature must be considered in designing
and selecting the correct system. Apply Nobel Technical Dept. for further information.
4.2.
How to remove packaging
The vessels are shipped wrapped in a plastic foil; remove it with care before starting-up. The
control board and pulse sender water meter 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 quartzsand 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. 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.

4.4.
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 7).
• After completed the loading, close the upper man-hole (or upper head)
• Fix the control board to the wall.

Hydraulic connections
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 no. 2) to the treated water line, inserting the pulse
sender water meter (for series AM/DV, AM/RDV, AM/D METER and AM/RD METER only)
downstream of the outlet connections.
• Connect the drain valves (nos. 1 and 6) to a floor drain. The gate valve mounted downstream
of the valve no. 6 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; 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 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.
• Complete the line from the brine drawing fitting (on the injector of the column) 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).
• 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.
• 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 driving of the lever simulates the acting of the coil. Hence, for the NC (normally closed)
solenoid valve, it 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 provided.

5.
End cycle and regeneration
The softeners are equipped with an electronic programmer with microprocessor that allows
to run automatically the regeneration. The end of the service cycle (briefly "end-cycle"), can be
featured according to different modes, depending of the entered programme.
The end-cycle should be programmed according to the quality of available water and the
consumption of water.
The max quantity of available soft water that the equipment can supply between two
following regenerations is to be calculated as follows:
cycle of the softener (m³ ∗ ºFr)
= m³ of available soft water per cycle
total hardness of raw water (°Fr)
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 m3 x °Fr)
The water meter sends 1 pulses every 100 liters of water supplied; the programmer will
increase one unit for every pulse and will show the volumes in hectoliters (hl).
5.1.
Volume mode (standard for AM/D METER and AM/RD METER models)
End-cycle is reached when the preset volume of water has been supplied; in the same time the
regeneration starts.
The time of service is also counted (parameter-counter B5), although this feature has not any
influence on the end-cycle.
The countings of time and volume of service are re-set to zero at any regeneration.
5.2.
Time mode (standard for AM/DT and AM/RDT models)
End-cycle is reached after that the pre-set time of service (in hours) is elapsed, but the
regeneration starts at a pre-set time of day. The pre-set number of hours of service does not
have an absolute value, since the unit will continue in supplying water till the subsequent preset time of regeneration; hence to schedule one regeneration per day it is the same entering 3
hours or 23 hours of time of service. This feature should be taken into consideration during the
programming operation.
It is suggested to enter multiple of 24 hours decreased of 4 hours as time of service (20, 44, 68,
92, etc).
Although it is allowed to schedule up to 3 different times of regeneration in the same day, it is
suggested to pre-set only one time, in order to avoid problems due to unproper preparation of
the brine (inadequate time of dissolution of the salt).
5.3.
Delayed volume mode
End-cycle is reached when the preset volume of water has been supplied, but the regeneration
starts at the pre-set time of day.
The time of service is also counted (parameter-counter B5), although this feature has not any
influence on the end-cycle.
The countings of time and volume of service are re-set to zero at any regeneration.
5.4.
Delayed volume and time mode (standard for AM/DV & AM/RDV models)
End-cycle is reached when anyone of the two pre-set limits (volume or time) is reached, but the
regeneration starts only at a pre-set time of day.
The countings of time and volume of service are re-set to zero at any regeneration.

5.5.
Regeneration
The regeneration of resins can be automatically or manually controlled.
An additional regeneration can be manually started, at any time, by pushing the button
"START" for at least 3 second.
• The pushing of the button "START", while a regeneration is already
running, does not have any effect.
• An undesired running regeneration can be stopped at any moment, just by
pushing the button "RESET" for at least 3 second.
CAUTION :
The regeneration can also run during power failure, by hand-driving the lever of the pilot
solenoid valves: the driving of the lever simulates the acting of the coil. Hence, for the NC
(normally closed) solenoid valve, it 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 provided.
The correspondent membrane valve (controlled by the pilot solenoid one), if NC type, is
open when the solenoid valve is open, and viceversa if the membrane valve is NO (normally
open) type.

For the time of each phase see § 8.6 page .
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 resins which are mixed together and carries 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 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, an internal by-pass line allows the system to supply un-treated
water; for AM/METER and AM/RD METER models, a membrane valve mounted on
the outlet line avoids suplying of untreated water.

5.6.
Inhibit of the regeneration
It is possibile to inhibit the starting of regeneration by mean of an external command, using
the input I3 of the programmer (see electrical wiring connection)
Hence, when the end-cycle is reached, the column will remain on REGENERATION
REQUIRED until the inhibit signal is switched off.
In the cases the time working modes are selected, the starting of the regeneration depends
on the pre-set time of regeneration. Hence when the inhibit signal is switched off, the
regeneration starts only at the pre-set time of day.
Even if the inhibit signal is still on, it is also possible to start manually the regeneration, as
above explained, by pushing the button “START” for at least 3 second.
6.
Special working modes
READ THIS CHAPTER ONLY IF THE EQUIPMENT WILL BE USED WITH DIFFERENT
FUNCTIONS THAN STANDARD ONES.
The programmer used for the equipments models AM/D, starting from november 2004, allows
to select all the working modes described for every models of equipment.
The limit to the selection of working modes depends on the different hydraulic arrangements of
the several models.
AM/DT and AM/RDT models
The models AM/DT and AM/RDT are not equipped with pulse sender water meter; hence they
cannot work in any volume working modes.
Whether modified with additional installation of a pulse sender water meter, these models will
became alike equipments AM/DV and/or AM/RDV ones.
AM/D METER and AM/RD METER models
All the described working modes can be selected; in any case, the units do not supply water
during regeneration.
AM/DV and AM/RDV models
All the described working modes can be selected; in any case, the units supply (untreated)
water during regeneration.
CAUTION :
for volume controlled models (V and METER), the selecting of a time working
mode does not avoid the volume working mode. Hence, the end-cycle features
at the pre-set time of day (time mode) but also when the pre-set volume of
supplied water is reached. In order to set the time only mode, it is suggested to
enter a very high volume as end-cycle (for example 900000) that will never be
reached, or just take out the wires of the pulse sender. This working mode can
be useful whether the consumption of water is very discontinuous and not
constant (during long time), hence it is requested to run the regeneration even
there is not consumption of water.
The countings of time and volume of service are re-set to zero at any
regeneration.

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 beginning, it is suggested to operate manually, hand-driven the valves, as above
explained at the § "Regeneration". This way will allow to stop, to run for longer time or to repeat
each phase as desired.
The following operations must be performed one after another, in the listed order.
To start-up the unit, proceed as follows:
• be sure that the control panel is switched OFF.
• close the gate valve along the backwash drain line
• open the shut-off valve upstream of the system, as well as the by-pass valve, keeping closed
the valve downstream of the system
• hand-drive the solenoid valve E4 to close the membrane valve no. 4
• hand-drive the solenoid valves E2 and E3 to open the backwashing membrane valves
• open slowly and gradually the gate valve on backwash drain 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, adjust the drain valve in order that the flow
rate will be the highest allowable without any leakage of resins 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 valves E4 to open the membrane valve no. 4.
• Hand-drive the solenoid valve E1 to open the drain membrane valve no. 1.
The rinse phase must run until all the water coming out the drain is perfectly clear.
• Hand-drive the solenoid valves E1 and E2 to conclude the regeneration; the column is now
ready for service.
• Switch ON the control panel.
• Open the outlet valve and close the by-pass valve.
Starting now the unit is on service and feeds treated water.
At the end of the first regeneration, put the salt into the brine tank (it can also be completely
filled). It is required to use clean salt, better the type in tablets.
Take care not to put salt inside the protection pipe.

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 and/or compressed air 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.
10.1. 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).
