1. The raw water entering the system flows through a particlefilter (1) with a pore size of 5m to remove physical impurities(particles)
The pressure drop at the filter can be determined by the
upstream and downstream manometers (2), which thenallows conclusions to be drawn on the degree of foulingto the filter.

2. The downstream solenoid valve (3) is closed when thesystem is switched off
This is necessary because otherwise permeate would beproduced by the pressure of feed water, even when thesystem is switched off. The system would then be "operated" at an incorrect operating point, resulting in poorpermeate quality.
3. The pressure switch (4) continuously checks the feed waterpressure because if the inlet pressure is too low then thiswould negatively affect the performance of the system
If the pressure drops below a preset minimum then thesystem is switched off.
4. The high pressure pump (6) feeds the raw water at a correspondingly high pressure to the spiral winding modules in thepressure pipes (9,10); a partial flow (ultra-pure water, permeate) flows over the membrane and a second partial flow(concentrated water, concentrate) is fed to the drain or isrecirculated
5. The angled retaining valve (27) thereby prevents counterpressure at the concentrate outlet by means of a high pressure pump
6. The permeate and the flow volume of the concentrate can beset using control valves (15,18)
7. The partial flows can be read off at the flow meter (13,16)8. The microprocessor controller (12) monitors function and dis
plays malfunctions
9. The controller calculates the quality (salt content) of the purewater using a conductivity measuring cell (11)
It thereby continuously checks the salt content of the per
meate and stops the system if a limit value is exceeded

5 Assembly and Installationn User qualification, mechanical assembly: trained qualified per
sonnel, see Chapter 2.2 Users' qualifications on page 7
n User qualification, electrical installation: Qualified electrician,see Chapter 2.2 Users' qualifications on page 7
n During assembly and installation of the system, the local instal
lation regulations, general regulations and the technical data ofthe system must be observed.
The position numbers refer to the flow diagram inChapter System overview on page 11
5.1 Preconditions for assemblyNOTICE!Preconditions for assembly The location of the system must be dry and free of
frost and the protection of the system from chemicals, dyes, vapours and weather conditions mustbe guaranteed. The ambient temperature must notexceed 45 C, even before start-up. Immediateheat sources, e.g. radiant heaters, as well as directsunlight, must be avoided
The minimum raw water pressure must be at least
3 bar and the maximum pressure must not exceed6 bar. Pressure fluctuations of more than +/- 0.5bar are not permitted. It might therefore be necessary to install a pressure reducer in the supply lineof the reverse osmosis system
A sewer junction must be available to drain off theconcentrate. This must be acid and alkali resistantand large enough to allow the respective volumeflow of concentrate to drain off freely
The power supply must have sufficient output

5.2 AssemblyCAUTION!Possible consequence: Slight or minor injuries, material damage.
The reverse osmosis system must be placed onto
a solid, even surface . The bearing capacity of the surface must be at
least the weight of the system + the weight ofthe water
The system must be fixed to the ground at itsinstallation location
A shut-off valve must be mounted between thesystem and the water supply
NOTICE! Place the system near to a water connection and
sewer junction To reduce the switching rate of the system to a
minimum during irregular permeate consumption,and to fully exploit the total power (daily output) ofthe system, we recommend installation of a permeate storage tank
5.3 InstallationWARNING!The electrical connection as well as all other electricalwork must be carried out by a qualified electrician.
n Connect the system to the water line
n Connect the system to the power supply Terminal arrangement 230 volt version (No. 1004192): on page 55accordingto the terminal plan
5.3.1 Systems with cleaning systemCAUTION!The system is designed so that when in operation, thepermeate flows off freely into a permeate tank. If aconsumer is directly connected to the system thenmake sure that no counterpressure can build up in thepermeate line when stopping the system. This woulddestroy the membranes. We recommend you install areturn valve in the line.
1. Connect the permeate outlet with the permeate tank or consumer2. If installed, connect the level switch of the permeate tank tothe controller

6.2 FunctionIn manual operating mode, the Dulcosmose
reverse osmosis system starts running immediately after beingswitched on and can be switched off with the STOPSTART key.
The level-controlled operating mode with 2 level switches is usedfor automatic filling of a permeate tank. The system only starts upafter the permeate level in the permeate tank has dropped belowthe minimum level. If the upper level is reached when filling then
the Dulcosmose switches off. The system can be externallylocked by a pause contact.
The raw water pressure is checked before system start. If the rawwater pressure is insufficient then the system goes into fault mode.After expiration of a waiting time, the raw water pressure isrechecked. If there is still insufficient raw water pressure after themaximum permissible number of checks then no additionalattempts are made.
If there is sufficient raw water pressure then the solenoid valveopens and the high pressure pump starts. Permeate is generated.The permeate conductivity is monitored during operation. If thepermeate conductivity does not drop below the maximum permissible conductivity within a maximum flushing time then the systemgoes into fault mode.
6.3 Optional chemical cleaningAn optional cleaning station is available for system sizes ecoPRO600 to 2700. The cleaning module can be retrofitted for system
sizes ecoPRO 600 to 1500. The module is installed as shown onFig. 5. The cleaning module is integral to the system for systemsizes ecoPRO 1800 to 2700.

Chemical cleaning of the reverse osmosis module is required atregular intervals and is supported by the controller. Chemicalcleaning is started manually after filling the cleaning tank withcleaning agent. The flushing pump starts. Chemical cleaning isstopped by manual switch-off. All valves are closed manually. Thecleaning pump is switched off.
6.4 DisplayNOTICE!After switching on the mains supply, the controllerstarts in "system OFF" mode or in the last active operating mode. If the contact for the external pause or thepermeate tank full level switch is activated at switch-on then the system starts in "idle" mode.
Pressing the STOPSTART key during raw water or permeaterinsing stops the rinse procedures. The system
switches off immediately.To do this, press the STOPSTART key for at least 2 seconds.

6.5.3 Set level control of permeate tankLevel-controlled operating mode: The level-control with 2 levelswitches allows a permeate tank to be automatically filled. When
the level control is enabled, the Dulcosmose system only starts upon switching on after the permeate level in the permeate tank hasdropped below the minimum level The system switches off automatically once the upper permeate level is reached.
Manual operating mode: In manual operating mode, theDulcosmose system starts running immediately after beingswitched on and can be switched off with the STOPSTART key.
6.5.4 Set cell-constant conductivity sensorCAUTION!Incorrect cell constantAn incorrect cell constant results in an incorrect con
ductivity measurement.
The cell constant of the conductivity sensor used must be entered.The entry is made in steps of 0.01.
6.5.5 Set the temperature compensation of the conductivity measurementConductivity is a temperature-dependent variable. The controllercan compensate for the influence of the temperature on the conductivity in two ways. The simplest method is temperature compensation using a Pt 100 temperature sensor. If no temperature sensoris installed, the permeate temperature can be entered manually. Ifthe temperature is entered manually then no temperature is displayed in the standard display.
6.5.6 Set compensation constant (Cal.-factor)CAUTION!Incorrect compensation constantAn incorrect compensation constant or temperature
setting results in an incorrect conductivity measurement.
The compensation factor (Cal.-factor) can be selected. In mostcases, a temperature compensation of 1 % / Kelvin is used. Thecompensation constant can be adjusted during operation to calibrate the conductivity display.
6.5.7 Set maximum conductivityIn conjunction with the permeate valve (optional) the monitoring cir
cuit for the conductivity ensures that only permeate with therequired conductivity reaches the consumer. The system is startedup with the permeate valve opened. As soon as the permeate conductivity drops below the maximum permissible conductivity, the

permeate vale closes in systems that have no permeate rinsingand the water us then fed to the consumer. In systems with permeate rinsing, the permeate valve only closes after the cleaningtank is full. If the maximum permissible conductivity is not undershot during the flushing time then the system goes into fault mode.The permeate conductivity continues to be monitored during operation. As soon as the conductivity exceeds the maximum permissible value, the permeate valve opens. If the conductivity once
more drops below the maximum permissible conductivity then thepermeate valve closes. Otherwise, the system goes into fault modeafter the maximum flushing time has expired. The permeate conductivity is not monitored during all rinsing procedures The permeate valve is opened. The function of the conductivity sensor isnot monitored by the controller. If conductivity value "0 S/cm" isdisplayed then the conductivity sensor must be checked.
6.5.8 Wait time and maximum number of attempts in case of water shortage
After switching on the Dulcosmose system manually or after thelower level in the permeate tank is undershot, the inlet valveopens. The water pressure is checked. If there is sufficient waterpressure then a system start rinsing procedure is run.
If there is not enough water pressure then the inlet valve closesagain The system goes into fault mode. The water pressure is re-checked after expiration of a wait time If there is still not enoughwater pressure after the maximum number of attempts then nomore attempts are made.
If the water pressure breaks down after expiration of the pantrinsing time while the high pressure pump is starting up then thepump is switched off. A second pump start-up commences a shorttime after this If the water pressure again breaks down then thesystem goes into fault mode. No additional attempts are made.
The water pressure continues to be monitored while the system isrunning. If the water pressure drops while the system is runningthen the system is immediately switched off. As previouslydescribed, the water pressure is then checked several times andthe system restarts if there is enough water pressure . If there isstill insufficient water pressure after the maximum permissiblenumber of attempts then no more attempts are made and thesystem goes into fault mode The operation relay of the controlleronly drops off if the system goes into fault mode.
6.5.9 Set rinse time of system startNOTICE!Rinse time of system startThe rinse time of the system start-up must be set so
that after expiration of the rinsing time, the motor valveis fully opened and the metered chemicals are distributed within the complete system.

Open the inlet and rinse valve (optional) for system start rinsing;the high pressure pump remains switched off. In case of systemswhere agents are added to stabilise hardness, the system startrinse serves to ensure there is an even distribution of the metered
chemicals on the raw water side of the Dulcosmose systembefore starting up the high pressure pump. In case of Dulcosmose
systems fitted with slow-opening motor-driven valves, the systemstart rinse also serves to completely open the valve before the
pump starts up
6.5.10 Set start-up time of high pressure pumpCAUTION!Maximum start-up timeIf the start-up time is too long then may result indamage to the pump. Exact specifications are contained in the operating manual of the pump.
The water pressure is not monitored during the pump start-up time.A longer pump start-up time is especially required for larger systems to prevent incorrect switch-off due to a supposed watershortage during the pump start-up time.
6.5.11 Set maximum flushing timeIf the permeate conductivity does not drop below the maximumconductivity during the maximum flushing time then theDulcosmose system switches off and the pant goes into fault
mode.
6.5.12 Set maximum filling time of cleaning tankDulcosmose systems with the "permeate rinsing" option have 2level switches in the cleaning tank whose contacts close as thelevel increases. The top level switch ends the filling procedure ifflushing has already completed. After removal, the cleaning tank isfilled automatically by the permeate valve the next time the
Dulcosmose system is started. The lower level switch serves asdry-run protector for the cleaning pump If the cleaning tank is not
filled within the maximum filling time then the Dulcosmose
systemswitches off and the Dulcosmose system goes into fault mode.
6.5.13 Set frequency and duration of raw water rinse in operation .
The raw water is rinsed at regular intervals during operation of theDulcosmose system. To do this, the rinse valve (optional) openswhile the system is running and the permeate valve opens duringthe rinsing time. Any coating that might have formed on the mem
brane is removed and rinsed off . This function is switched off byentering "0 hours" for the wait time . Raw water rinsing during operation is always carried out by the high pressure pump.

6.5.14 Raw water rinsing at end of operation
For raw water rinsing, the rinse valve (optional) opens for the duration of the rinsing time after switching off the system. The concen
trate is thereby rinsed off at the raw water side of the Dulcosmose
system. The inlet valve remains open. Normally, the raw waterrinsing is carried out with the high pressure pump switched off.However, depending on the configuration of the system, rinsingmay also be necessary when the high pressure pump is switchedon. If no rinse valve is installed then "concentrate suppression" canbe carried out. This is always done with the high pressure pumpswitched on.
6.5.15 Permeate rinse, set rinse timeDuring permeate rinsing (optional), the raw water side of the
Dulcosmose system is rinsed out of the rinsing tank with per
meate for the rinsing time. The cleaning tank is automatically filledthe next time the system is started up. If the minimum level isreached in the tank during permeate rinsing then the cleaningpump switches off. The warning message "dry run" is displayed.The "dry run" message goes out after completion of the rinsingtime. No error message is issued.
6.5.16 Cleaning pump for chemical cleaningChemical cleaning of the reverse osmosis module is required atregular intervals and is supported by the controller. A cleaning
system may or may not be installed, depending on the configuration of the Dulcosmose system .
6.5.17 Set maximum idle timeWhen the level controller is switched on, the Dulcosmose systemautomatically goes back into operation for the interval operationtime as soon as the maximum idle time is overshot and no pauselock is enabled. This automatic restart significantly reduces themicrobial contamination during idle as well as biological fouling ofthe membrane elements. This function is switched off by setting
the idle time to "0 h".
6.5.18 Set interval operating timeCAUTION!Permeate tank overflowThe permeate tank might overflow during interval operation. A suitable level drain must be installed in thepermeate tank.

When the level controller is switched on, the Dulcosmose systemautomatically goes back into operation for the interval operationtime as soon as the maximum idle time is overshot and there is noexternal pause lock.
6.5.19 Set analogue outputThe permeate conductivity can also be written with a recorder fordocumentation purposes. To do so, connect the recorder to thestandard output of the controller. It is possible to choose from a 0to 20 mA and 4 to 20 mA standard signal: 0 or 4 mA correspondsto the conductivity; 0 S/cm, 20 mA ca be assigned to any conductivity.
6.5.20 Pause functionThe Dulcosmose system can be switched on and off by opening
and closing an external contact connected to the Pause input ofthe controller. It is possible to select whether the Dulcosmose
system starts up with an open or closed pause contact. If theDulcosmose system is switched off by a pause contact, then rawwater rinsing or permeate rinsing may occur. If there is a watershortage during this then the permeate rinse is immediatelyskipped.
6.5.21 Set minimum mains voltagen The minimum mains voltage that can be tolerated by the con
troller can be set in this menu. Permissible range: 79 - 108 %
Default setting: 90 %
100 % corresponds to 230 volt

9.CAUTION!Maximum permeate outputPossible consequence: Slight or minor injuries,material damage.
The yield corresponds to the permeate outputrelative to the consumption of raw water.
Permeate outputs compliant to the specifications must never be increased in any circumstances
This damages the membrane and resultsin degradation in the quality of the permeate
If the permeate output is exceeded then theoperating pressure must be reduced
This is done by increasing the recirculation of concentrate at the ball valve (18)
If conductivity is higher than required then lower the yield, i.e.discard more concentrate. To do this, slowly open the ballvalve (15) until the required conductivity is reached.
10. Set 3-way ball valve (14) for permeate to the permeatetank position

8.3 Chemical cleaning and disinfectionCAUTION!Possible consequence: Slight or minor injuries, material damage.
Also carry out immediate cleaning if the conduc
tivity rises and the permeate output drops in constant conditions (raw water quality and temperature)
To increase the lifetime of the modules, carry outtwo prophylactic cleanings with acid and one withalkali every year
When operating reverse osmosis systems, deposits form on themembrane surface after a while. These deposits can either be inorganic (e.g. lime, plaster, iron, manganese), or organic (bacteria,germs). Depending on the type of deposits, this results in adecrease in permeate quality and/or a reduction in the flow of permeate.
Chemical cleaning allows the majority of deposits to be removedeasily.
The modules must be cleaned according to instructions. Theapproximate amount of cleaning fluid required for this, or its composition, is contained in the following table.
WARNING!DisinfectionPossible consequence: Fatal or very serious injuries.
Observe the safety data sheet
Wear protective goggles and gloves. If the chemical touches your skin then immediately rinse offwith lots of water and contact a doctor.
Peracetic acid is injurious when breathed inand can result in serious burns.
Danger of fire if acid comes into contact withflammable substances.
CAUTION!Specifications for metering quantity of chemicalsPossible consequence: material damage.The specifications for the metering quantity of chemicals depends significantly on the water used to manufacture the cleaning fluid and can therefore only serveas an estimated value.
