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/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. s.r.l.milano - ITALY Page 5 of 24 p4.05-amd-tvm_mi-r5.doc

4. 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. GOLFARI HOOKING CAUTION : DO NOT LIFT OR MOVE THE UNIT HOOKING OR CATCHING BY THE PRE-ASSEMBLED PARTS. GAMBE DI SOSTEGNO 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. s.r.l.milano - ITALY Page 8 of 24 p4.05-amd-tvm_mi-r5.doc

4.5. 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: SOLENOID MEMBRANE VALVE MEMBRANE VALVE VALVE SERIES AM/DT AM/RDT AM/DV AM/RDV SERIES AM/D METER AM/RD METER EV no. TYPE no. TYPE no. TYPE 1 NC V1 - V2 - V5 NC - NA - NC V1 - V5 NC - NC 2 NC V3 NC V2 NA 3 NC V6 NC V3 - V6 NC 4 NC V4 NA V4 NA 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. s.r.l.milano - ITALY Page 9 of 24 p4.05-amd-tvm_mi-r5.doc

4.6. Electrical wiring connections Make wiring connections in the control board QE according to following directions (see WIRING DIAGRAM): o o Power supply 110 240V, 50 60 Hz, directly to the inlet clamps of the main switch o o o o GND For softeners of series AM/DV, AM/RDV, AM/D METER, AM/RD METER only : o + o Pulse sender water meter WM o 11 o " " " " Available for external commands : I3 input (24V cc) to inhibit the starting of regeneration The following free voltage contacts (max 3A-24V), directly on the LOGO unit, are also available for remote signals : Q1 Q2 Q3 Q4 enabling signal to start CL180 signal of running regeneration signal of running service signal of service for duplex mode working 4.6.1. Special connections for AM/D METER, AM/RD METER only For AM/D Meter and AM/RD Meter models only, the following features are also available: I4 I5 I6 input (24V cc) for low level water tank input (24V cc) for high level water tank input (24V cc) to inhibit the starting of service The level switches, whether used, must be the type open without water; the oulet valve of the column will open below the low level and will close over the high level. If not any level switch is connected, the outlet valve is always open during service. It is also allowed the installation of 2 softeners METER models, but working much the same way of a DUPLEX softener, hence only one softener will be on service while the other one is on regeneration or stand-by. In this case, make the crossing connections between the two control panels, as follows (directly on their own LOGO units) : column A column B + Q4 I6 Q4 Q4 + Q4 I6 s.r.l.milano - ITALY Page 10 of 24 p4.05-amd-tvm_mi-r5.doc

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 CaCO 3 = 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 m 3 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. s.r.l.milano - ITALY Page 11 of 24 p4.05-amd-tvm_mi-r5.doc

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 1 second. CAUTION : 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 "STOP" for at least 1 second. 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. OPEN VALVES FOR MODELS PHASE DRIVEN SOLENOID VALVES (= OPEN) AM/DT AM/RDT AM/DV AM/RDV AM/D METER AM/RD METER SERVICE // V2 - V4 V2 - V4 BACKWASH E2 - E3 - E4 V2 - V3 - V6 V3 - V6 DRAWING AND SLOW RINSE E1 - E2 - E4 V1 - V3 - V5 V1 - V5 FAST RINSE E1 - E2 V1 - V3 -V4 - V5 V1 - V4 - V5 For the time of each phase see 8.5 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. s.r.l.milano - ITALY Page 12 of 24 p4.05-amd-tvm_mi-r5.doc

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 1 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. s.r.l.milano - ITALY Page 13 of 24 p4.05-amd-tvm_mi-r5.doc

7. Control panel 7.1. Functions of the logical programmer The logical programmer Siemens mod. LOGO controls the logical working of the whole system. The display allows the visualization of the current time and date, the status of the input signals (marked as I) and the output signals (marked as Q), the several messages enabled by the programme. It is also possible to modify the setting of the entered numerical parameters (marked as B). The numbering of the inputs and outputs is written on several lines, each of them is related to ten (I1 I9, I10 I19 etc.) By pushing the buttons or the display shows, alternatively, the visualizations of the service : current time and date, inputs, outputs, (M, to be ignored), function buttons (ESC+C..). By pushing the buttons and the messages enabled by the programme are visualized.

9. 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. s.r.l.milano - ITALY Page 20 of 24 p4.05-amd-tvm_mi-r5.doc

10. 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). s.r.l.milano - ITALY Page 21 of 24 p4.05-amd-tvm_mi-r5.doc
