5.1 Preconditions for assemblyPreconditions for assembly:n Make sure that the installation site of the system is frost-free

and guarantee that the system is protected from chemicals,dyes, solvents, vapours and the effects of weathering. Do notallow the ambient temperature to exceed 40 °C, even beforecommissioning. Avoid direct heat sources, e.g. radiant heaters,as well as direct sunlight.

n The raw water pressure must be 3 bar ... 6 bar. Pressure fluc‐tuations of more than +/- 0.5 bar are not permitted. It maytherefore be necessary to install a pressure reducer in thesupply line to the system.

n A sewer connector must be available to discharge the concen‐trate. This needs to be resistant to acid and alkali and largeenough to allow the respective volumetric flow of concrete todrain away freely.

n Make sure that there is an adequate power supply.

5.2 Assembly

CAUTION!Possible consequence: Slight or minor injuries.Material damage.– Install the reverse osmosis system on a solid,

even base.– Make sure that the load-bearing capacity of

the floor is at least the weight of the system+ the weight of the water.

– The system must be fixed to the base at itsinstallation place.

– Mount a shut-off valve between the system andthe water supply.

n Place the system near a water and sewer connectionn The installation of a permeate storage tank is recommended to

reduce the switching frequency of the system to a minimumwith irregular permeate consumption and to fully exploit thetotal output (daily output) of the system

7 Setting up the systemn User qualification: trained user Ä Chapter 2.2 ‘User qualifica‐

tion’ on page 9Before removing water from the system, it is essential that thesystem is rinsed and thus freed of preservative substances.Ä Chapter 8.1 ‘Commissioning rinse of the system’ on page 33

Pre-set parametersAll parameters are factory-set to sensible defaultvalues but they can be adjusted if required.

7.1 OperationIn manual mode, the PLC immediately starts up the system once ithas been switched on if the key switch is turned to the “RO” posi‐tion. You can also switch off the system by turning the key switchto the “Off” position.Level-controlled operation with 2 level switches is used for theautomatic filling of a permeate tank. The system only starts upwhen the permeate level in the permeate tank is below the min‐imum level. The PLC switches off the system when the upper levelis reached during automatic filling. However, you can also switchoff the system externally using a pause contact.The inlet pressure of the raw water is checked by the PLC prior tocommissioning the system. If the inlet pressure of the raw water isinsufficient, then a fault message is generated by the system. Atthe end of a delay time, the inlet pressure of the raw water ischecked again by the PLC. If the inlet pressure of the raw water isstill inadequate after the maximum permitted number of attempts,then no further attempts are undertaken and the system remains ina permanent fault state.If the inlet pressure of the raw water is sufficient, then the solenoidvalve opens and the high-pressure pump starts up. Permeate isproduced. The conductivity of the permeate is checked by the PLCduring the operation of the system. If the permeate conductivity isstill above the maximum permitted conductivity within the max‐imum free rinse time, then a fault message is generated and thesystem remains in a permanent fault state.

7.2 Chemical cleaning (optional)Chemical cleaning of the reverse osmosis module is required atregular intervals and is supported by the PLC.1. Fill the cleaning tank with a suitable cleaning solution.2. Start chemical cleaning.

ð The cleaning pump is started manually.

3. Once the cleaning time you have selected has ended,cleaning needs to be ended manually.

ð All valves are closed manually.

The cleaning pump switches off.

ð This takes you to the Parameter menus.

7.7 Setting up the permeate tank level control[PERMEATE LEVEL CONTROL]The level control with 2 level switches enables a permeate tank tobe automatically filled. When level control is activated, the systemonly starts up when the permeate level in the permeate tank hasfallen below the minimum level. The system switches off automati‐cally once the upper permeate level has been reached.

7.8 Setting the standby/standing control[Standby/standing control]This switches the standby/standing control on/off when the levelcontrol is active. See Ä Chapter 7.15 ‘Setting the maximumstandby time’ on page 27 and Ä Chapter 7.16 ‘Setting the oper‐ating time interval’ on page 28.

7.9 Pause function[EXTERNAL PAUSE]You can switch the system on and off by opening and shutting anexternal contact connected to the pause input of the PLC. You canselect whether the system is started up with an open pause contactor with a closed contact. A raw water rinse is performed, if pro‐grammed, when the system is switched off by the pause contact.

7.10 Setting the system’s inlet pressure bridge[START-UP, PRESSURE BRIDGE]The inlet valve opens when the system is switched on. This is thetime at which the system ignores the pressure switch until the inletpressure is stable to prevent the system from immediately gener‐ating a fault message due to the inlet pressure possibly being toolow.

7.11 Setting the system’s start-up rinse cycle[START-UP, RAW WATER RINSE]During the system’s start-up rinse cycle, the inlet valve opens whilethe high-pressure pump remains disabled. The system’s start-uprinse cycle fills the system with water and removes air. With sys‐tems in which chemicals are metered to stabilise the feed water,the system’s start-up rinse cycle is also used to guarantee theeven distribution of the metered chemicals on the raw water side ofthe reverse osmosis system before the high-pressure pump startsup.

7.12 Setting the pump start-up time[START-UP, HP PUMP STARTING]The inlet pressure is not monitored during the start-up phase of thepump. A longer start-up time is needed, particularly with larger sys‐tems, to prevent the system being incorrectly switched off to anassumed shortage of water while the pump is starting up.

: If the start-up time of the pump is too long, it can also result indamage to the pump. Precise information can be obtained in theoperating instructions for the pump.

7.13 Setting the waiting time after water shortage[PARAMETER MENU-7 WAITING AFTER W. SHORTAGE]

If the inlet pressure is insufficient, the inlet valve closes and thesystem waits for this set time before attempting once again to openthe inlet valve.

7.14 Setting the maximum number of attempts with water shortage[PARAMETER MENU 8 MAX. TRIALS OF W. SHORTAGE][WARNING! WATER SHORTAGE DURING RAW WATER RINSEWAITING TIME IS RUNNING 00:50 MIN BRIDGE BY ESC+]The inlet valve opens after the system has been switched on orwhen the liquid level in the permeate tanks drops below the min‐imum level. The inlet pressure is checked. The system's start-uprinse cycle is performed once the inlet pressure is sufficient.

If the inlet pressure is too low, then the inlet valve closes again.The system goes into warning mode.The inlet pressure is checked again after expiry of a wait time.If the inlet pressure is still too low after the programmed maximumpermitted number of attempts, then no further attempts are under‐taken.

If at the end of the rinse time of the system the inlet pressure dropswhen the high-pressure pump starts up, then the high-pressurepump is switched off. A second pump start takes place a short timelater.If the pressure once again drops below the minimum pressurelevel, then the system goes into fault mode.

The inlet pressure continues to be monitored during operation ofthe system. If the inlet pressure once again drops below the min‐imum pressure during operation of the system, then the system isimmediately switched off. Then, as described above, the inlet pres‐sure is checked again by the maximum programmed number ofattempts.If the pressure is still inadequate after the maximum number oftests, then no further attempts are undertaken and the system gen‐erates a fault message. The PLC’s operating relay is only de-ener‐gised in the event of a fault of the system.

7.15 Setting the maximum standby time[PARAMETER MENU 9 MAX.

7.26 Setting maximum conductivityMonitoring the conductivity ensures that only permeate with therequired conductivity reaches the consumer. The maximum per‐missible conductivity can be set in the integrated conductivity con‐trol system mounted on the system. The procedure for setting themaximum permissible level is described in the corresponding con‐troller instructions supplied with the system. The setting can easilybe adapted to your needs.If the conductivity exceeds the maximum value set in the PLC, thenthe system switches to warning mode but continues to operate. Awarning message is generated on the PLC and the maximum freerinse time is simultaneously started. If the conductivity falls belowthis maximum value within the maximum free rinse time, then thewarning disappears. If the conductivity does not fall below the max‐imum permitted value within the maximum free rinse time, then thesystem generates a fault and stops operation. Please also refer tothe chapter Ä Chapter 10 ‘Troubleshooting’ on page 45 for furtherdetails.

8.2 Commissioning process for the system1. Switch on the electrical power supply.2. Switch on the system using the Schneider 455 key switch

and check the direction of rotation of the high-pressure pump(with 3-phase motors); if necessary, reverse the polarity ofthe wiring, as otherwise the pump will not build up enoughpressure and will be damaged.

3. Use the ball valves (15) and (18) to adjust the concentrateflow (flow meter 16) and the permeate flow (flow meter 13)according to the specification of the system.

: Under no circumstances increase the permeate capacityaccording to the specification. Increasing the permeatecapacity will damage the diaphragms and result in impairedpermeate quality.

4. Reduce the operating pressure if the permeate capacity isexceeded. Increase the concentrate return at ball valve no.18 to reduce the operating pressure.

5. Reduce the output of the system if the conductivity is higherthan wished. To reduce, drain off more concentrate by slowlyopening ball valve no. 15 until the required conductivity levelis reached.

6. Set the 3-way ball valve (14) for permeate to the “Permeatetank” position.

7. Connect the drain ball valve (21) of the cleaning tank.

ð The system is now in operation.

8. Complete checklists 1 and 2, referring to the appendix ofthese operating instructions.

9. Fill out checklists 1 and 2 weekly, which enables you todetermine if and where a fault may have occurred should onearise.

10. Use the Schneider 455 key switch to switch off the system11. Connect the permeate connector to the permeate tank or the

consumer.12. Switch on the system again.

9.3 Chemical cleaning and disinfection9.3.1 Introduction

CAUTION!Possible consequence: Slight or minor injuries.Material damage.– Carry out immediate cleaning if the conductivity

rises and the permeate output drops in con‐stant conditions (raw water quality and tem‐perature).

– To increase the lifetime of the modules, carryout two acid and one alkaline prophylacticcleaning processes every year.

When operating reverse osmosis systems, deposits form on thesurface of the diaphragm over time. They can either be of an inor‐ganic nature (e.g. lime, gypsum, iron, manganese), or they canalso form an organic film (bacteria, germs). Depending on the typeof deposits, this can result in a decreased permeate quality and/ora reduction in the flow of permeate.Chemical cleaning enables the majority of deposits to be removedwith ease.First carry out an acid and then an alkaline cleaning process wherethere is a combination of mineral deposits and organic dirt.Clean the modules according to the instructions. The quantity ofcleaning fluid required for this and/or its composition can be foundin the following table.

CAUTION!Specifications for the chemical metering quantityPossible consequence: Material damage.The specifications for the chemical metering quan‐tity largely depend on the water used to producethe cleaning fluid and are therefore only guidelinevalues.– The acidic cleaning fluid should have a pH

value of 3– Never allow the pH value to fall below 2
