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. (see § 3.5 page 6). 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.

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
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
(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.

4.4. 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.

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 :
• AM/V and AM/RV SERIES :
• AM/METER and
AM/RMETER SERIES :
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:
