9 B Basic information 1 Laws, regulations, standards In the interest of good health, rules cannot be ignored when it comes to the processing of drinking water. This operation manual takes into consideration the current regulations and stipulates information that you will need for the safe operation of your water treatment system. Among other things, the regulations stipulate that only approved companies are permitted to make major modifications to water supply facilities and that tests, inspections and maintenance on installed devices are to be performed at regular intervals. 2 Water Due to dynamic substance and water cycles, harmful elements, which are only partly and only slowly biodegradable are increasingly released into nature. Over time, these elements therefore accumulate in ground and surface water. Removing them again from natural water bodies represents a particular challenge. Grünbeck rises to this challenge and aims at generating unpolluted drinking and process water. The water works provide us with pure drinking water that is suitable for consumption. However, if the water is to be used for technical purposes, further treatment is frequently required. 7

10 3 Functional principle of reverse osmosis Principle: Concentrate: Pre-treated feed water Permeate Fig. B-1: Functional principle Osmosis Osmotic pressure Reversed osmosis Solution of high concentration Solution of low concentration Fig. B-2: Reverse osmosis principle Solution of high concentration Solution of low concentration Solution of high concentration (concentrate) Solution of low concentration (permeate) In the osmosis process, watery solutions of different concentrations are separated by a semi-permeable membrane. In keeping with the law of nature, the concentrations try to equalise. On the side of the higher original concentration, the so-called "osmotic" pressure is generated. In case of reverse osmosis, this osmotic pressure is countered by a higher pressure. The consequence: the process proceeds in the reverse direction. A particular advantage of the reverse osmosis technology compared to other water treatment processes is the fact that - apart from the removal of dissolved salts - bacteria, germs and dissolved organic substances are also reduced. 8

18 4 Appropriate application The reserve osmosis system is designed for the demineralisation of drinking water according to the German Drinking Water Ordinance (TrinkwV). The generated water is primarily used for industrial applications. A corresponding pre-treatment is required and the application limits (paragraph 5) must be adhered to. Note: In case of water that does not comply with the stipulations of the German Drinking Water Ordinance (TrinkwV), a water analysis is required beforehand. The continuous permeate capacity is subject to the temperature and was defined at 15 C. The permeate capacity decreases by up to 3 % per degree centigrade of the feed water temperature. Note: This reverse osmosis system adjusts the permeate capacity automatically subject to the temperature. The recovery (concentrate to drain) as well as the concentrate recirculation are adapted to the modified permeate capacity. The system is adjusted to the permeate requirements to be expected at the installation site, it is not suitable for major deviations. The system may only be operated if all components are installed properly. Safety devices and equipment must NEVER be removed, bridged or tampered with. Appropriate application of the device also implies that the information contained in this operation manual and all safety guidelines applying at the installation site be observed. Furthermore, the maintenance and inspection intervals have to be observed. 4.1 System idle time If the system is out of operation for more than 14 days, it must be preserved by Grünbeck's technical customer service/authorised service company. The maximum time, the system can remain in the preserved condition is 6 months. In case the down time is longer, the system must be preserved again in regular intervals by Grünbeck's technical customer service/authorised service company. Prior to resuming operation, the preserving agent must be flushed from the system. 16

19 5 Application limits For the application of the reverse osmosis system, the limit values stipulated in the German Drinking Water Ordinance represent the upper limits for the admissible substances contained in the water. Total hardness < 0.1 dh 1) (0.18 f; mmol/l) Free chlorine not detectable Iron < 0.10 mg/l Manganese < 0.05 mg/l Silicate < 15 mg/l Chlorine dioxide not detectable Turbidity < 1 FTU Colloid index (SDI) < 3 ph range 3-9 1) Different application limits for the total hardness do apply for the optional pre-treatment AVRO resp. antiscalant. Note: The permeate originating from the reverse osmosis system is not potable but requires additional treatment (blending, hardening) if it is to be used as drinking water. 17

26 D Installation 1 General Installation Instructions The installation site must provide adequate space. Only the left side (pressure pipes) of the system may be placed flush to the wall. In front, behind and on the right side of the system, adequate clearance for installation and service work must be provided (> 50 cm). A foundation of a sufficient size and adequate load carrying capacity must be provided. The required connections must be provided prior to the installation. For dimensions and connection data, please refer to table C Preliminary work Unpack all system components. 2 Water installation Check for completeness and soundness. Place the reverse osmosis system at the designated location. Note: Also observe the operation manuals that have been supplied with the optional accessories (see chapter C-6.2) for your system (if applicable). Certain binding rules must always be observed when installing a reverse osmosis system. Additional recommendations are given in order to facilitate the handling of the system. The installation instructions described below are also illustrated in fig. D-1. Binding rules The installation of a reverse osmosis system represents a major interference with the drinking water system. Therefore, only authorised experts may install such systems. Please observe the local installation guidelines and the general regulations. Install a drinking water filter upstream of the system (e.g. BOXER K). A system separator must be installed upstream as well. Install a water softener upstream. Mount an activated carbon filter, if necessary (take water analysis into consideration). Provide a drain connection (minimum DN 50) to discharge the concentrate. Note: If the concentrate is directed to a lifting system, the delivery rate of the lifting system should at least have the concentrate volume flow indicated in table C-1. Warning! The installation site must have a floor drain. If no floor drain is available, an adequate water stop device needs to be installed (refer to option C-9). Warning! In case of a power failure, floor drains with a discharge to a lifting system will be out of operation. 24

27 3 How to connect the system Remove the protective caps at the feed water, permeate and concentrate to drain connections of the system. Connect the feed water. Connect the concentrate to drain according to DIN 1988 and install the pipe aeration above system level. Make the connection between permeate outlet and supply tanks. 1 BOXER K 1" drinking water filter 6 2 System separator GENO -DK Delta-p water softener 8 4 GENO -softwatch Komfort 5 Activated carbon filter AKF Reverse osmosis system Permeate tank with sterile air filter and level sensor Pressure booster system GENO FU-X 2/40-1 N Fig. D-1: Installation drawing Note: The feed, concentrate resp. permeate pipe provided by others on site must feature a provision to separate the pipes (e. g. a screw connection). Note: The permeate and concentrate pipes have to be made of corrosion-proof material. 25

28 4 Electrical installation As the reverse osmosis system features a frequency converter for the high-pressure pump, problems with the residual current circuit breaker installed in the feeder may occur. We therefore recommend: Use of an AC/DC sensitive RCCB with a response threshold of 30 ma. For the power supply of the system, a power outlet 3 x 400 V / 50 Hz/L/N/PE with a fuse protection of at least 25 A has to be provided by others on site. The aluminium system rack must be connected to the equipotential bonding on-site. The earth wire must have a minimum cross section of 6 mm² Cu or 10 mm² Al. The necessary connecting materials (screw, hammer nuts, washers, etc.) are located in a bag in the system power distributor (see Chapter F-4.1). The connection to the equipotential bonding is required because the speed-controlled high-pressure pump has a ground leakage current of > 10 ma during its designated operation. 4.1 Circuit diagram of power distribution The power distribution features the mains switch of the GENO OSMO-X system and is accessible if the control unit is flipped downwards. If required, the entire "production line" (softening + residual hardness monitoring or antiscalant dosing, reverse osmosis, pressure booster system) may be supplied by the power distribution. The power line of an antiscalant dosing pump is plugged into the mains socket of the power distribution in order to be able to quickly replace it during servicing. 26

35 E Start-up The work described below may only be performed by trained experts. For safety reasons, the start-up must be performed by Grünbeck's trained and authorised technical customer service/ authorised service company. Note: Incorrect parameter settings or still missing signal connections may cause malfunctions due to which the flushing of the preserving agent cannot be started. 1 How to flush the system 1.1 How to flush off the preservation agent For the duration of storage and transport, the membrane(s) is (are) protected by means of a preserving agent. First of all, this preserving agent must be flushed off. After switching on the power supply for the first time, select the subsystem menu. Tap on it. The following pop-up window will appear in the touch display of the GENO -tronic control unit: 33

36 By tapping on "START", the feed water solenoid valve, the control valve concentrate to drain and sporadically the control valve concentrate recirculation open. The preservation agent is washed out to the drain. Attention! While the preserving agent is being flushed off, the system is deaerated at the same time. When skipping or prematurely aborting the step "flushing" and putting the system in operation, there are the following two risks High-pressure pump is running dry. The preserving agent gets into the permeate tank or into the permeate line provided by others on site - these can only be cleaned/flushed with difficulty. Note: The flushing of the system can be restarted manually. Refer to chapter F-4.1: To do so, select the operating mode "flushing". 34

37 F Operation 1 Introduction Note: Instructions in bold are absolutely essential to ensure that work can continue. All other instructions can be ignored if the value shown on the display remains unchanged. Settings in the technical service programming level may only be performed by Grünbeck's technical customer service/authorised service company or by persons expressly authorised by Grünbeck. Warning! Incorrect settings may lead to hazardous operating conditions which cause injury, illness or damage to property. The operation manual must be strictly adhered to! Only make the settings described in there! 2 Screen layout of the GENO -tronic operating element 2.1 Home screen The home screen is the superordinate screen for all subsystems connected to/interconnected with the control unit of the GENO - OSMO-X: Here, it is set out from left to right how the water flows through the individual treatment steps. On the far left, the system range (cogwheels) for fundamental settings is located. Lightly tapping on a subsystem provokes a switch-over to the Info level of the respective subsystem. Status line, colour signals the system status System range Subsystem range 35

38 2.2 Info level of If the subsystem features an ON/OFF function such as the reverse osmosis system OSMO-X, the Info level has an ON/OFF button, too: Green = subsystem ON, Red = subsystem OFF. With the Home button, you may return to the Home screen. By pressing on the illustration, you may access the submenu. Home button Access to the GENO -OSMO X menu ON/OFF button Operating mode, current measuring values The following information is stored in the Info level of the OSMO-X (can be accessed via arrow keys ^/v): Operating mode (locked / flushing / manual operation / automatic) Permeate flow [l/h] Current set value for permeate capacity [l/h] Permeate conductivity [µs/cm] Permeate recovery [%] Water temperature [ C] Service in [d] AVRO RO1 B5 (only in case of AVRO pre-treatment) [h] Concentrate to drain [l/h] Concentrate recirculation [l/h] Permeate pressure (only for Online version) [bar] AVRO RO1B5 treatment current (only in case of AVRO pre-treatment) [ma] Output of regulating valve RO1V3 [%] Output of regulating valve RO1V2 [%] Conductivity of inlet and concentrate (only if optional conductivity measurement is available) [µs/cm] Remaining duration of the service interval [d] Feed water flow [l/h] Feed flow [l/h] 36

39 2.3 Change, save, reject parameters In a menu with permanently stored selections, any choice (line) can be selected by tapping on it. The middle line is in slightly larger print, however. Save your selection with this button. Quit the menu with this button without changing the prior selection. The numerical and the alpha-numerical menu each feature the same operating logic: Save your selection with this button. Quit the menu with this button without changing the prior selection. Save your selection with this button. Quit the menu with this button without changing the prior selection. 37

40 2.4 Acknowledgement of errors/signals In case of a pending signal or malfunction, the status line changes its colour and on the home screen, the subsystem concerned has a coloured frame. Yellow = signal Red = error Tap on the status line >> Switch to error list The error list may show one or several entries. Tap on the entry you are interested in >> switch to the acknowledgement window Button to return to the Home screen The acknowledgement window will show an illustration of the subsystem concerned. Acknowledgement button of the signal/error Button to call up a help text including the telephone number of the technical customer service. Button to return to the error list The error can either be acknowledged or left pending. In any case, you will get back to the error list. Acknowledge signal/error Leave signal/error pending 38

41 2.5 Screen saver The screen saver is displayed automatically if the screen is not touched for 5 minutes (or after an adjustable period of time). As soon as the touch screen is tapped on or a signal or an error occurs, the display returns to the basic display. 3 System range 3.1 System menu I System menu I can be accessed without entering a Code. The parameters stored apply to all systems in case more subsystems than just the are present and are operated via the GENO -tronic operating element. 39

42 Note: Prior to removing the SD card, make sure that the data logging was terminated with "Nein/No"! Note: The SD card used must be formatted FAT32. We recommend proper formatting instead of quick formatting. Note: The SD card socket is integrated in the operating element of the GENO -tronic - to insert the card, the control unit of the must be opened. Parameters Factory setting Setting range Operating language German German English French Dutch Italian Russian Spanish System designation Date, time Data logging Start Start/ Stop Comment 18 digits, alphanumerical, text will appear in the upper left corner of the Home screen Incl. automatic switch-over from daylight saving time to standard time All measured values of all subsystems (Info level) are logged on the SD card.

Save current parameter record on the SD card Note: The protective foil over the touch screen may only be wiped with a damp cloth and a mild soapsuds solution at the most! Never use cleaning agents for plastics or stronger cleaning agents! Otherwise there is a risk that the foil will assume a milky colour and therefore be difficult to read! 40

43 3.2 Data logging on an SD card The measured values on the SD card theoretically comprise an entire "production line", from the softening or anti-scaling dosing) to the reverse osmosis (electrodeionisation is still not possible at present) and via the pure water tanks up to the pressure booster. The log files are not yet very clear when viewed with a text editor: It is recommended to open the file with a spreadsheet program (e.g. MS Excel) so that the structuring is easier to identify. The system serial number is included in cell B1. The assignment of all other information can be found in the following table. Unavailable sub-systems should be ignored. 41

46 3.2 System menu II 3.3 Software version The purpose of the system menu II is to log on all existing components of the "production line" that are to be displayed in the GENO -tronic. Not Code protected: Indication of the software version of the control unit and the GENO -tronic operating element. 4 Sub-system reverse osmosis system The menu of the reverse osmosis system is structured as follows: 44

47 4.1 User programming level The user programming level can be accessed without entering a Code. Parameters Factory Setting Comment setting range Operating mode Locked Locked/ Flushing/ Manual operation/ Automatic The desired operating mode (except for Locked) has to be started in the Info level by means of the I/O button (the colour of the button changes from red to green): Locked = delivery state, no system operation possible Flushing = flushing volume stored in the system size will be flushed to the drain once Manual operation (not possible in case of system output Online) = permeate production continues as long as the system stays switched on via the I/O button. No switch-off command via tank full detection will be processed. Automatic operation = permeate is produced subject to the level in the permeate tank or the permeate pressure 45

48 Parameters Switch-on pressure (only in case of system output Online) Switch-off pressure (only in case of system output Online) Automatic restart Factory setting Setting range Comment [bar] In automatic operation, the system starts the permeate production if the switch-on pressure is undershot. [bar] In automatic operation, the system terminates the permeate production if the switch-off pressure is exceeded. Note: The systems are designed for 4.0 bar. Forced operation Operation Operation/ flushing Conductivity monitoring RO1CQ1 Conductivity limit value RO1CQ1 Delay conductivity error/signal RO1CQ1 No No/Yes What to do after a power failure No = after return of power, the system signals "Error power failure ; automatic resp. manual operation remains stored but is blanked. YES = after return of power, the system continues running in the operating mode set previously and does not indicate an error. Signal Signal/ error [µs/cm] [min.] Behaviour in case of a longer period without permeate production (also refer to the customer service level): Operation = permeate production, switch-off command tank full is ignored (tank with overflow required) Flushing = Factory setting in case of system output Online: Flushing to the drain, highpressure pump is not running. Monitoring of permeate conductivity: If the programmed conductivity limit value is exceeded for the set delay time, the following options can be programmed: Signal: The system continues running although the limit value was exceeded. Error: The system switches off. 46
