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

There is no chemically pure water in nature. Even in the atmosphere,

rain water absorbs various substances that change the properties of the water to a greater or lesser degree. This process continues as the water passes through the ground layers, with the result that the water is enriched with increasingly large quantities of materials. Carbon dioxide (CO2) is particularly important here, since this substance increases the dissolving capability of the water even more. Consequently, drinking water contains quantities of dissolved sodium, potassium, calcium, magnesium, iron, manganese, copper, zinc, chlorides, fluorides, sulphates and also nitrates, nitrites, phosphates and silicates that vary greatly from location to location.

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 from natural water bodies again represents a particular challenge. Grünbeck rises to this challenge and aims at generating unpolluted drinking and industrial 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.

Fig. B-2: Reverse osmosis principle

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, particles and dissolved organic substances are also reduced.

3.1 Functional principle of the AVRO system

AVRO is an alternative anti-scaling process to the common traditional processes of "softening" or “antiscalant dosing”. Contrary to these processes, AVRO does not require any addition of auxiliary additives. The chemical composition of the generated concentrate is not modified. There is only a doubling of the concentration (standard recovery 50 %).

Hydraulically, the AVRO is installed in the concentrate pipe downstream of the membrane.

The treatment unit consists of two inert special electrodes to which a low current is applied. Seed crystals (calcium carbonate) are generated at the cathode and are permanently directed via the concentrate recirculation. The salts of the supersaturated concentrate continue to grow on these seed crystals, and they are finally washed out to the drain with the residual concentrate flow. This reliably prevents scaling (deposits of insoluble salts on the membrane). Some of the calcium carbonate remains on the cathode of the AVRO and due to increasing electrical resistance, limits the service life of the AVRO treatment unit to 3000 operating hours (permeate production) or 5 years.

2 | Functional description

Via a fine filter (filter element), the water is directed to the inlet of the

feed water section. The water flows to the high-pressure pump via the inlet solenoid valve with a downstream “pressure switch for minimum pressure”. By means of a control valve, the pressure generated by the high-pressure pump is reduced to the required operating pressure and the water is directed to the membrane. The membrane separates the water into the partial flows permeate and concentrate. A partial flow of the concentrate is returned to the feed water via an orifice regulating independently of pressure and thus ensures a steady flow over the membrane and increases the economic efficiency of the reverse osmosis.

At the same time, the concentrate volume flow is run via an AVRO

treatment module where seed crystals are formed at a cathode due to the application of direct current. These seed crystals are then washed out with the residual concentrate and thus the reverse osmosis membrane is protected from clogging. Whenever the system is switched off or in case of disturbances, the substances retained on the membrane are flushed off by means of the inlet solenoid valve and a solenoid valve switched in parallel to the control valve for concentrate.

The hydraulic set-up of the system is designed in a way that the concentrate volume and the permeate volume are registered by means of flow sensors and are displayed in the control unit. The system recovery can also be called up in the control unit.

Downstream of the membrane, the permeate produced can be delivered into the heating system with a counter-pressure of up to 3.5 bar.



Note: If the counter-pressure on the permeate side increases, the permeate output decreases.

Filling mode:

If "filling mode" is selected via the selector switch on the controller,

three waves are visible in the controller. The pressure switch is interrogated as the start criterion.

Workshop mode:

If "workshop mode" is selected via the selector switch on the control-

ler, one wave is visible in the controller. Selection of the operating switch is used as the start criterion. After 24 hours, permeate is produced over time. The workshop mode prevents germs from infecting the system, thereby ensuring a constant permeate quality.

4 | Intended use

The reverse osmosis system AVRO-flex 400 is designed for the de-

mineralisation of drinking water and for the filling of heating systems / district heating networks and other systems with fully demineralised water as per the stipulations of VDI 2035, sheets 1 and 2.

If the demineralised water as per VDI 2035 is used to fill systems <

0.11°dH (0.196 °f; 0.0196 mmol/l), it may - subject to the feed water - be necessary to install a desaliQ:BA mixed bed cartridge downstream.

The continuous permeate output of the system is subject to the temperature and is defined at 15 °C. As the feed water temperature rises and falls, the permeate outputs can decrease by up to 3% per °C (falling temperature) or rise by the same amount (rising temperature).

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 must NEVER be removed, bridged or otherwise tampered with.

Intended use 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.

The reverse osmosis system AVRO-flex 400 is exclusively designed for use in the industrial and commercial sector.

4.1 Standstill of the system

If the system is out of operation for more than 14 days, the reverse

osmosis system must be preserved by Grünbeck's technical service/ authorised service company. The maximum time, the system can remain in the preserved condition is 6 months.

In case the downtime is longer, the system must be preserved again in regular intervals by Grünbeck's technical service/authorised service company. Prior to resuming operation, the preserving agent must be flushed from the system.

AVRO-flex 400, the limit values for admissible substances contained in water which are stipulated in the German Drinking Water Ordinance do represent the upper limits for the system.

 < 22° dH (39.2 °f; 3,92 mmol/l) without water analysis

 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 < 3

 pH range 3 - 9

A water analysis is required in case of a total hardness > 22 °dH or

sulphate > 500 mg/l.



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.

Attention! In case of an admissible excess of the sulphate concentration due to geogenic conditions, the recovery with regard to the standard settings according to layout might need to be reduced.

D Installation

1 | General installation instructions

The installation site must provide adequate space. A foundation of a

sufficient size and adequate load carrying capacity has to be provided. The required connections must be provided prior to the installation of the system. For dimensions and connection data, please refer to table C-1.



Note: For the installation of systems with optional accessories (refer to Chapter C, item 6.3), also observe the operation manuals supplied with these components.

1.1 Water connection

Certain binding rules must always be observed when installing a mobile reverse osmosis system AVRO-flex 400. Additional recommendations are given in order to facilitate the handling of the system. The installation instructions described below are also illustrated in fig. E-2.

Binding rules

The installation of a mobile reverse osmosis system AVRO-flex 400 represents a major interference with the drinking water system. Therefore, only authorised experts may install such systems.

 Observe local installation guidelines and general regulations.

 Install a drinking water filter (e. g. BOXER KD) upstream of the sys-

tem.

 Install a system separator upstream – not required when using a

GENO-therm filling device.

 Install an activated carbon filter upstream, if required.

 Provide a drain connection (minimum DN 50) to discharge the con-

centrate.



Note: If the concentrate is directed to a lifting system, the delivery rate of the lifting system should at least be 800 l/h.

Warning! The installation site must have a floor drain. If no floor drain is available, an adequate safety device needs to be installed (refer to Chapter C, item 6.3 “Optional accessories”).

Warning! Floor drains that discharge to a lifting system do not work in case of a power failure.

Recommendation

If the mobile reverse osmosis system AVRO-flex 400 is not connected

to the optional filling device GENO-therm, a sampling valve should be installed directly upstream and downstream of the mobile reverse osmosis system AVRO-flex 400. This simplifies the sampling for the regular quality control (functional check).

E Start-up

The work described below may only be performed by trained experts. We recommend having Grünbeck‘s technical service/authorised service company start up the system.

1 | How to connect the system to the water supply

 Connect the feed water / raw water hose to the system

(refer to fig. E-1, item 3).

 Connect the permeate hose to the system and to the system to be

filled (refer to fig. E-1, item 2).

 Connect the concentrate hose to the system (refer to fig. E-1, item

1). Run the hose with a gradient to the drain and connect in accordance with EN 1717 (free outlet).

2 | How to flush the system

For the duration of storage and transport, the membrane is protected

by means of a preserving agent. This preserving agent must be flushed off before starting up the system for the first time. To do so, the concentrate hose (refer to fig. E-1, item 1) and the permeate hose (refer to fig. E-1, item 2) have to be routed to the drain.

2.1 How to flush off the preserving agent



Note: For more detailed information on the handling of the control unit, refer to Chapter F.

Switch on the mains switch and switch the operating mode selector

switch to the "OFF" position.

Open both solenoid valves ("DEAERATE") via Code 113, parameter EnL: 1 and flush off the preserving agent from the system for a duration of 30 min. To do so, open parameter with P button, set ENL: 1 with ▲ button and confirm with P button.

Complete program step “DEARATE”: Open parameter with P button, set EnL:0 with ▼ button and confirm with P button.

Exit the “EnL” program by simultaneously pressing the buttons ▼and ▲.

2.2 Filling mode

In filling mode (refer to fig. E-2), e.g. heating / cooling water systems, direct the hose supplied with the system from the permeate connection of the reverse osmosis system to the filling valve or to the GENO-therm filling device.

The pressure switch is set to a switch-off pressure of 2.5 bar = system pressure. If a higher or lower system pressure is required, this can be set via the pressure switch (refer to fig. C-2, item 13). Then switch on the reverse osmosis system via the selector switch at the controller housing. The system produces permeate. Close the filling valve and monitor at which pressure the system switches off. Use the adjusting screws to set to the desired switch-off pressure/system pressure.



Note: Based on the permeate output of the reverse osmosis, a max. pressure of 3.5 bar can be reached. With an increasing counter-pressure, the continuous permeate output will decrease.

2.3 Workshop mode

To prevent damage to the membrane due to germs (bio-fouling), the

mobile reverse osmosis system AVRO-flex 400 must be run in workshop mode during the entire periods of standstill (refer to fig. E-3). In this case, the permeate line as well as the concentrate line are connected as per DIN EN 1717. In the workshop mode, water is rejected for a certain time set in the controller (factory setting 15 min.) every day.



Note: The system must be connected to the power supply as well as to the water/waste water network for the entire period of standstill (transports up to 48 h excluded).



Note: If installed, the shut-off valve on the permeate side must be open!

5 | Operation of reverse osmosis system AVRO-flex 400

5.1 How to set the system recovery

A certain part of the feed water must be rejected in order to prevent

the membrane from clogging due to scaling. The ratio of the produced permeate volume to the feed water volume is called recovery.

5.1.1 How to set the permeate volume

Switch on the system via the ▲ button at the control unit. With the control valve for the operating pressure (refer to fig. F-3, item

1), throttle the high-pressure pump in a way that the system-specific permeate flow of 400 l/h is attained.



Note: The current permeate flow can be displayed via the controller (refer to Chapter F, paragraph 2.1 “Reading the operating status”).

5.1.2 How to set the concentrate volume

Set the concentrate flow at the concentrate needle valve (refer to fig.

F-4, item 1).

To safeguard against the valve changing its position, it features a safety screw which is centrally located at the green cap.

The concentrate flow in a standard system has to be set in a way, that a recovery of 50 % is attained (400 l/h of permeate flow, 400 l/h of concentrate flow).



Note: The current concentrate flow and the recovery can be displayed via the controller (refer to Chapter F, paragraph 2.1 “Reading the operating status”).

Attention! If the set recovery is not met, scaling (precipitation of dissolved salts) occurs on the reverse osmosis membrane.

H Maintenance and care

1 | Basic information

In order to guarantee the reliable function of the systems over a long

period of time, some maintenance work has to be performed at regular intervals. All regulations and guidelines which apply at the installation site must be strictly adhered to.

 Check the quality and the system volume flows every day.

 Maintenance has to be performed by Grünbeck’s technical ser-

vice/authorised service company or by a specialised company. Maintenance is subject to the load but at the latest has to be performed once a year.

 An operation log and the corresponding test log must be kept in or-

der to document the maintenance work performed.



Note: By concluding a maintenance contract you ensure that all maintenance work will be performed in due time.

The maintenance work performed must be documented in the checklist, refer to appendix "Operation log".

2 | Inspection (functional check)

You may perform the daily inspections yourself.

Please refer to the following summary for the tasks to be performed within the framework of an inspection.

Summary: Inspection work

 Read the recovery



Note: Minor deviations are normal and cannot be prevented technically. In case of considerable deviations from the standard, notify Grünbeck's technical service.

 Take the remaining time of the AVRO treatment unit’s maintenance

interval into consideration (refer to Chapter F, paragraph 2.1). If the remaining time is < 100 hours, notify Grünbeck’s technical service/ authorised service company to have the treatment module replaced.

 Take the remaining time of the maintenance interval [d] into consid-

eration (refer to Chapter F - paragraph 2.1 “Reading the operating state”). In case the remaining time of the maintenance interval is < 30 days, inform Grünbeck's technical service about the impending service.

 Check the system’s tightness to the drain. Solenoid valves are not

tightened, visible in the display (refer to fig. F-2, items 9 and 10). In this state, no water must creep to the drain.



Note: Leaky solenoid valves will cause the system to consume more water. The recovery will be reduced.

3 | Maintenance

According to DIN 1988 part 8 / A 12, maintenance work at the systems may only be performed by Grünbeck’s technical service/authorised service company or an approved specialist company.

For this kind of systems, an operation log - a checklist has to be kept.

In this operation log, the customer service technician records all maintenance and repair work performed. In case of malfunctions, this log helps to identify possible sources of error. In addition, the log documents the proper system maintenance.



Note: Make sure that all maintenance work is recorded in the operation log as well as in the corresponding test log.

Summary: Maintenance work

 Replace the filter element.

 If necessary, replace the filter element of the activated carbon filter.

 Check the permeate quality; flush or replace the membrane, if nec-

essary. So-called flushing instructions (order no. 700 950) are available for authorised service personnel.

 Replacement of AVRO treatment unit, if necessary

(limit value: 3000 h or 5 years)

 Solenoid valves – check function, clean if necessary.

 Check the flow volumes and recalibrate the water meters.

 Check the state of the entire system and check the entire system

for tightness.

 Mechanical resp. electrical functional and performance check of all

aggregates (pumps, valves).

 Prepare a written maintenance log on the state and function of the

system and the maintenance work performed, incl. evaluation and assessment of the operating values and water analysis results.



Note: The maintenance work performed must be documented in the checklist, refer to appendix "Operation log".
