4. FUNCTION AND STRUCTURE

3.1 Mode of operation
General principle of reverse osmosis Osmosis is a natural process, it is understood as the one-sided diffusion of a liquid (here the feed water) through a semipermeable membrane. A semi-permeable membrane is only permeable for certain substances.
As the liquid moves through a semi-permeable membrane, the pressure on the side with the lower concentration decreases and at the same time the pressure of the more concentrated solution increases until a balance is reached, stopping the water flow. Pressure difference between the two liquids is called “osmotic pressure”.
Reverse osmosis, on the other hand, is a technical process in which the natural process is reversed. It involves applying a pressure higher than the osmotic pressure to the concentrated liquid so that the water flows in the opposite direction through the semi-permeable membrane and thus separates the salts solved in the water.
Using this principle, water can be demineralized for drinking water as well as for process and industrial applications.

3.2 Influencing factors
The performance of the reverse osmosis membrane depends strongly on the following parameters:
Water inlet pressure at the membrane: ­ By lowering the working pressure, a reduction in permeate production can be achieved. ­ By increasing the working pressure, an increase in permeate production is also achieved. ­ The pump pressure can be changed by turning the screw on the pump (see chapter 8.4). ­ Be careful not to exceed the maximum pump pressure!
Salt content of the feed water: The higher the salt content, the faster the membrane wear.
Temperature of the feed water: The ROL unit is set up for a feed water temperature of 15°C. Any difference from this temperature will affect the production quantity and the quality of the permeate.

The following table shows the variation of the permeate production quantity by 3% per differing 1°C.

The colder the feed water, the lower the permeate production and the better/lower the conductivity. The warmer the feed water, the higher the production quantity, but the lower the permeate quality.

3.3 Operating conditions of the unit

The ROL system can be fed with water from the normal water supply if the water has a maximum hardness up to 50°fH. In order to avoid a reduction of the operating capacity, the water to be treated must comply with certain parameters:

turbidity Iron Manganese Aluminium SDI (Silt Density Index) Water temperature Free chlorine Hardness COD TOC TDS SiO2 conductivity

< 1 NTU < 0,15 ppm < 0,05 ppm < 0,05 ppm < 3 5 to 25 °C < 0.25 ppm < 50 °fH < 10 mg/l < 3 mg/l < 1000S/cm < 15 ppm < 1000 ppm

Notice: Ensure that the water is pre-treated by using a softener or an antiscalant.

3.3.1 Recovery value
You can optimise the permeate production by adjusting the flow rates (Ref. 1). The basis for this is the respective recovery value of the plant (see technical data). If the recovery value is 68%, this means a permeate production quantity of 68% of the feed water used for this purpose. The difference to 100% shows the concentrate share.

You can optimise permeate output by adjusting the flow rates (Ref. 1). The basis for this is the relevant recovery value of the system (see technical data). For example, the recovery value for the ROL320 is 68% at a raw water temperature of 18 °C and a TDS value of 500 ppm.

The recovery value is calculated as follows:

RECOVERY (%) = Permeate 100 (Permeate + Concentrate)

Regulate the flow rate of the concentrate through the BV03 valve and read it off the FI03 flow meter. The circulation is controlled by the BV02 valve and read off at the FI02 flow meter. The pressure regulated in this way on the membranes guarantees the spe- cified production output.

The feed water temperature clearly influen- ces both productivity and the quality of the permeate. If the temperature rises (even by only a few degrees), productivity increases (which results in a better recovery value); however, conductivity increases at the same time.

3.4 Operating sequence
The feed water (raw water) is pumped through the pre-filter, which guarantees the dechlorination and a final filter capacity of 5 µm. This ensures the necessary clarity of the water at the membrane inlet. It is next softened by the addition of an antiscalant. The feed water pressure must be at least 2 to 5 bar during normal operation to ensure a correct supply pressure at the pump inlet.
The water then flows through the water inlet solenoid valve SV1 and is then directed by the pressure pump at high pressure to the membrane(s).
The pressure switch PS HIGH provides a signal when the pressure exceeds 12 bar at the membrane inlet.
Pure water (permeate) passes through the membrane; the salts solved in the water are retained by the membrane and drained off (concentrate).
The permeate now flows via the pure water line (scope of delivery) to the expansion ves- sel or directly to the consumer.
The quality of the permeate leaving the system is controlled by the conductivity sensor (EC PROBOUT).
The production process stops automatically when the water outlet pressure has reached approx. 4 bar at the pressure switch PS MAX. The pressure in the following circuit is kept constant by the expansion vessel.
If the pressure in the following circuit at the pressure switch PS MIN falls below 2 bar (when the expansion vesel is empty), the unit starts permeate production again.
If the inlet pressure falls below 0.8 bar, the pressure switch PS LOW gives the corre- sponding alarm and interrupts operation.
The permeate production quantity achieved can be read off from the permeate flow rate display (Ref1). If this does not correspond to the the specifications in the technical data, please note the measures mentioned in chapter 4.2.

Notice: The reverse osmosis (R.O.) units of the ROL series cannot operate without an expansion vessel or permeate collecting tank.

5. MECHANICAL INSTALLATION
Caution: Risk of foot injuries!
Prevent unit from dropping during installation! Helping hand of a second person is advisable.
Caution: Risk of electrical shock!
Hazardous electrical voltage. During installation, the unit must be disconnected from power supply and secured against being switched on again. The absence of voltage must be ensured by a measurement.
5.1 Environment Parameters to be met and Mounting Recommendations
When selecting the installation site for the reverse osmosis unit, take the following into account: · The minimum clearances indicated in the fitting measures section must be observed in order to ensure adequate unit venti-
lation and allow for unob- structed access in case of maintenance · Protection class IP20 · By design, HygroMatik reverse osmosis units are not qualified for outdoor installa- tion (electronic components and water-
bearing parts may be damaged) · Ambient temperature must lie between · +5 and +40 °C (+41 and +104 °F) in order to protect the unit electronics against damage; frost may damage the steam cylinder,
the solenoid valve and pump, as well as make hoses burst · Avoid environments with excessive humidity, as it could have negative effects on the electronics. · Installation in closed rooms requires aeration and, if necessary, temperature conditioning in order to meet the envi- ronmental
conditions. · Make use of existing water connections for supply and draining. · For proper functioning of the level con- trol, plumb and level installation of the unit is required. · The optimal feed water pressure for the reverse osmosis units is in the range of 2 bar to 5 bar. If these values are not reached,
the installation of a pressure reducer or a booster pump is neces- sary. · The on-site waste water connection must be a free outflow according to DIN EN 1717. · The installation room must be well ven- tilated and equipped with a floor drain. Alternatively, a water stop device (e.g. leakage
detector) can be used. · Ensure that the system stands firmly.

6. WATER CONNECTION

Have all plumbing work done only by qualified personnel (plumber or specialist with equivalent training) to minimize risks.

Caution: Risk of electrical shock! Hazardous electrical voltage! Before starting installation work ensure that the unit is not yet connected to the power supply.

General Rules · Obey local water utility regulations · Verify that necessary safety measures have been taken ­ in compliance with either German Technical and Scientific Associa-
tion for Gas and Water (DVGW) guidelines (DIN EN1717) or local regulations ­ that eliminate backflow of polluted water into drinking water treatment facilities. This may require the installation of a system separator, allowable only when free discharge into the drainage system is given. · Ensure that there is a free outflow and drain according to DIN EN 1717. Pay attention to the minimum requirement for the free flow distance (between the drain hose and the siphon) of 26 mm to prevent microbial contamination. · Supply water must not exceed 25°C (77°F) · Allowable range of water pressure: 1,5 to 4 bar / 22 to 58 psi (150.000 to 400.000 Pa). If the pressure is below 1.5 bar, install a pressure booster, if it is above 4 bar, install a pressure reducer after the reverse osmosis system. · Install a drain tap shortly before the system to flush the pipe. Flushing the pipe prevents foreign particles such as swarf or sealing material from entering the system from the pipes.

Connection of the system supply

»

Make sure that the flow rate and pressure correspond to the values given in the technical data.

»

Ensure that the water supply stays closed. This system may only be supplied with water during commissioning

(see chapter 8) !

Connection of the concentrate discharge pipe. · The diameter of the concentrate pipe must be at least equal to the diameter of the connection piece (see technical data).

Notice: In any case, a particle filter (min. 100 µm) according to DIN 13443-1 should be installed before the reverse osmosis system. Without a water filter there is a risk of damage to the system.

Notice: The following applies to ROL units: · For safety reasons the water connections are not screwed during transport. They must be screwed during installation. · Remove the transport locks from the flow pipes.
Notice: for the Australian market and to comply with Watermark requirements, a watermarked approved dual check valve shall be installed in the supply line to the humidifier when connected to potable water. Should on the other hand the humidifier be fed with treated water from a Carel reverse osmosis system connected to potable water, the dual check valve shall be installed in the supply line to the reverse osmosis system.

8. INITIAL START-UP

Caution Danger due to incorrect operation! Commissioning may only be carried out by qualified personnel (electricians or specialists with equivalent training).
Caution Risk of electrical shock! Hazardous electrical voltage! Follow safety instructions for work on live components.
Notice: Remove the elongated transport locks from the flow tubes (Fl01-Fl03).
Notice: Do not connect the permeate line to the expansion vessel until all other commission- ing steps (especially flushing of the mem- branes) have been carried out.
Notice: At the beginning of each commissioning with the use of new membrane(s), the ROL unit produces a higher permeate quantity in the first 2-4 hours, which is combined with a higher conductivity.
Notice: The pump may only be operated with the water inlet valve open, otherwise it could be damaged. Exception: initial start-up.
Operation steps in the short overview: Step 1: Check mechanical integrity, water connection and cabling Step 2: Removal of the transport lock from the flow tubes (Fl01-Fl03) Step 3: Flushing the membranes Step 4: Adjustment of recovery value Step 5: Connect the permeate pipe to the extension vessel and thus also to the con- sumer (It is important that this step is only done at the very end of the commission- ing process) Step 6: Filling the anti-calcant canister and adjusting the dosing pump. Step 7: Observe device and check for leaks, eliminate leaks if necessary.

8.1 Flushing of the membrane(s)
When the system is started for the first time and each time it is put into operation after a period of non-use, you must remove the chemical maintenance solutions and/or standing water. If the system is not used for a longer period of time, the membrane(s) must be replaced!
Ensure no water pressure is applied!
In addition, the membranes must be gradu- ally moistened without being submitted to the working pressure (5-6 bar). The water must flow through the filters and membranes at line pressure for several minutes before the pump can be activated.

Notice: Do not use the water produced during this phase.

8.2 Adjustment of the permeate quality
Adjust the circulation volume (BV02) and the concentrate volume (BV03) to achieve the optimum recovery and permeate value (see technical data). The flow rates can be read off the flow measuring sensors FI01 (permeate) / FI02 (circulation) and FI03 (concentrate). Using the example of ROL-1000:

Fl01 Fl02
BV02 D E

Fl03
BV03 BV04 SV02

Fl01 permeate flow meter Fl02 recirculation flow meter Fl03 drain flow meter BV02 manual recirculation control valve BV03 manual drain control valve BV04 manual flushing control valve SV02 flushing solenoid valve D permeate conductivity probe E attachment for sampling permeate

Circulating flow rate: 450 l/h Concentrate flow rate: 470 l/h This results in a recovery value of 68 percent.

In general, this is calculated as follows:

RECOVER (%) = permeate*

x 100

permeate + concentrate

• quantity

Notice: · When using an upstream softening system you can reduce the amount of concentrate (lower water consumption) until a
recovery value of 75% is achieved. · Please also note the information on the correction value (chapter 4.2). · Use the red markings to document the required flow rates

Notice: If the permeate quantity (Fl01) is within the specified range (see technical data), continue with chapter 8.3

28 Initial start-up

WTS LARGE +0300131EN rel. 1.0 – 05.09.2022

ENG

8.2.1 Increase of the working pres- sure before the membranes
If the maximum permeate quantity (Fl01*) is not reached although the recovery value cor- responds to the specifications in the technical data, you can increase the permeate quantity by increasing the pressure before the membranes.

Notice: Do not exceed the permitted pump pressure!

This can lead to pump damage.

Select a low working pressure!

Although the diaphragms can be operated at a pressure of 5 to 12 bar, we recommend the lowest possible working pressure (5 to 6 bar), both during commissioning and during nor- mal system operation. This allows for a lon- ger service life of the diaphragm(s).

To increase the pump pressure, proceed as follows:

Rotary vane pump (in models from 100 l/h to 320 l/h):

»

Open or close the by-pass valve (bypass) with a slotted screwdriver

Fig. 8.a

Multi-step pump (in the models from 460 l/h to 1.000 l/h):

»

Adjust the ball valve downstream of the pump manually

Fig. 8.b

»

Watch the pressure change on the manometer downstream of the pump and the flow rate change on the

pure water flow meter.

»

Adjust until the desired flow rate is reached.

»

Let the system run for 30 minutes.

»

During this time, periodically check that the rated parameters (flow rates, pressures and conductivity) stabilise

within the limit values.

»

Take a permeate sample (at the extraction point (E*)) and, if neces- sary, carry out a chemical-physical and

possibly bacteriological analysis to check the suitability of the water for the intended purpose.

8.3 Continuation of initial start-up after successful adjustment

of the recovery rate

»

Connect the permeate pipe to the following consumer.

»

Open the shut-off cocks of the expansion vessel

»

Check whether the system switches off after reaching the operating pressure (approx. 4 bar).

When the pres- sure expansion vessel is completely filled, the pressure rises automatically (read the value on

the pressure gauge of the expansion vessel).

If the system does not switch off when the operating pressure exceeds approx 4 bar, consult HygroMatik.

»

Check the system for leaks.

»

If leaks appear, switch off the unit immediately. Locate and eliminate leaks

»

Repeat the tightness test

8.4 Filling the antiscalant tank
The antiscalant liquid is used to prevent cal- cium and magnesium residues present in the feed water from depositing on the membrane, causing a decline in performance and reducing operating life. The dosing pump feeds the desired antiscalant dose into the feed water circuit.
Filling the canister
Before filling the antiscalant canister, take the required amount of antiscalant (depending on the water hardness) from the table in the chapter Technical Data.

»

Using a measuring cup, thin the anti- scale in the canister with permeate (use the permeate produced during

the commissioning phase for this step).

»

Make sure not to damage the float when closing the cap on the tank.

Notice: To ensure the functionality of the seals, the system must be put into operation within one year of the delivery date.

8.7 Break of use
The functionality of the reverse osmosis plant is connected to the continuous production of permeate.
For a break in use of up to 10 days, the plant should remain supplied with electricity and water, because the plant periodically rinses the membranes (a periodic rinse of 30 sec- onds every 24 hours of break in use is fac- tory- set). For breaks in use of more than 10 days up to a maximum period of 1-2 months, the rinsing parameters should be set to 15 minutes every 48 hours.
Notice: During breaks in use, the extension vessel or the return pump vessel (if present) must also be emptied.

9. MAINTENANCE
8.1 General
Regular maintenance is essential to ensure that the CAREL units can achieve a long service life. The necessary maintenance work refers to components that are either subject to mechanical or electrical wear, or whose function is reduced by deposits. The optimum function and required maintenance intervals of a reverse osmosis unit depend mainly on the existing water quality and the permeate quantity produced. Different water qualities can extend or shorten the maintenance intervals.
The following factors in specific could lead to an early blocking of the membranes: · Blockage as a result of the deposit of iron or calcium sulphate and calcium carbonate · Blockage with organic material
In general, a replacement of the membranes becomes necessary if a change in the following basic system parameters (at the same temperature and salinity) is noticed: · Reduction of the permeate production to a value which is insufficient for the application downstream of the reverse osmosis
system. · Too much increase in the conductivity of the water produced to a value too high for the application downstream of the sy-
stem. · Increase of the membrane feed pressure.
8.2 Safety instructions for maintenance
Caution: Risk of electrical shock! Hazardous electrical voltage! Any work on the electrical system to be performed by certified expert staff (electricians or expert personnel with comparable training) only.
Notice: Take care of ESD protection! The electronic components of the control are very sensitive to electrostatic discharges. In order to protect these components during maintenance, steps must be taken to guard against damage from electrostatic discharge.
Notice: Removal and replacement of components If necessary, the parts of the UO unit may only be replaced by qualified personnel. Replacement work must always be carried out with the system at a standstill; contact the supplier or the manufacturer directly for this purpose.
Notice: Use disposable gloves when installing the pre-filter(s) and membrane(s) to protect them from contamination.
8.3 Routine maintenance
8.3.1 Change prefilter
The HygroMatik ROL units are equipped with two different pre-filters.
L

K J

Fig. 8.a
The CB-EC carbon filter (K) is used to reduce the chlorine content in the feed water (L). The presence of chlorine in the water may irreversibly damage the membrane. The car- bon filter works by chemical reaction, combin- ing and absorbing the chlorine molecules. Consequently, its performance will decline over time.

32 Maintenance

WTS LARGE +0300131EN rel. 1.0 – 05.09.2022

ENG

The CB-EC cartridge needs to be replaced:

·

every four months if the chlorine content in the feed water is less than 0.1 ppm.

·

every two months if the chlorine content in the feed water is between 0.1 ppm and 0.2 ppm.

The CPP micron filter (J) traps impurities around 5 µm in size. The filter works mechanically, letting the feed water fl ow through a filtering mesh. It is normal for the filter to become blocked over time, letting less water through and increasing the pressure drop.

The CPP cartridge needs to be replaced when the system feed water pressure (after having passed through the inlet filter car- tridges) is less than 1 bar during normal oper- ation (pressure read on pressure gauge PI01).

Before replacing the prefilter, check · that the ROL system is switched off · the inlet valve is closed and there is no pressure on the water line.

»

Remove the pre-filter with suitable tools.

»

Remove the old filter cartridge and clean the inlet.

»

Replace the O-ring if necessary.

»

Moisten the new O-ring and insert it.

»

Insert a new filter cartridge.

»

Mount the pre-filter with suitable tools.

»

Open the water supply and vent the filters via the screw in the upper part of the membrane container.

8.3.2 Filling of the antiscalant canister
The appropriately dosed antiscalant prevents lime deposits on the membranes. The filling level of the antiscalant canister must be con- stantly monitored. The consumption of the antiscalant mixture depends on the permeate production and the settings of the dosing pump.The reverse osmosis plant cannot work without antiscalant or softening, because oth- erwise the membranes would be irreversibly damaged. For this reason, the electronic con- trol stops operation and activates an alarm as soon as it recognizes a low level in the anti- scalant canister. To prevent this alarm and the following production stop, check the filling level of the canister regularly and refill it in time.

8.3.3 Replacing the UV lamp
The UV lamp has a limited operating life. The following intervals are recommended for replacement (whichever comes first): · 9000 operating hours · one year

8.3.4 Reset maintenance counter
Reset the maintenance hour counter in menu item 13 as described in the chapter device control.

8.4 Special maintenance and repairs

8.4.1 Membrane exchange

The membranes undergo a natural decline in performance over time, specifically:

·

annual reduction in water produced of 7%

·

annual increase in outlet water conduc- tivity of 10%

After a certain period of operation, in relation to the characteristics and volume of water treated, the membranes tend

to become blocked, with a decline in efficiency. This decline in membrane efficiency may depend on two main factors:

·

blockage due to precipitation of iron or calcium sulphate and carbonate

·

biological blockage

·

infrequent replacement of the CBC (carbon block fi lter)

Replacement becomes necessary when the system shows variations in the following fun- damental parameters (for the

same initial feed water temperature):

·

decrease in water produced to a level that is insufficient for the application connected downstream of the

reverse osmosis system.

·

excessive increase in the conductivity of the water produced to a level that is excessive for the application

connected downstream of the reverse osmosis system.

Daily maintenance
Check if the system is working cor- rectly. Check that there are no leaks in the water-carrying components. Check the water inlet pressure.

Notice: The system supply pressure (after the pre-fil- ters) must be at least 2 bar during normal operation. Replace the filter cartridges if the pressure loss is too high.

8.5.2
» » »

Weekly maintenance
Check the max. membran pressure (max.10 bar!). Check the water conductivity of the permeate with the control unit. Note down the data for the listed tests

Notice:

·

Note that the production quantity of the permeate increases with rising water temperature, while the quality

of Permeate is decreasing. Conversely, the production quantity decreases with decreasing temperature, while

the quality of the permeate improves.

·

The indication of the measured perme- ate conductivity value on the display of the control unit settles down

to the actual value within the first minutes.

8.5.3 Maintenance every two months

»

Check that there is not too much free chlorine at the outlet (less than 0.25ppm).

34 Maintenance

WTS LARGE +0300131EN rel. 1.0 – 05.09.2022

ENG

Replace the pre-filter cartridge:

»

Every 2 months if the free chlorine content is between 0.1 ppm and 0.2 ppm.

»

Every 4 months if the free chlorine content is less than 0.1 ppm.

Notice: The lifetime of the pre-filter and membrane(s) depends on feed water quality and permeate production rate.

Notice: Maximum permitted storage times of the membranes: · 6 months: if the membranes are already supplied with a chemical solution and/or impregnated with glycol; · 1 year: if the membranes are supplied dry or vacuum packed.

8.5.4 Maintenance by qualified per- sonnel

Every 6 months: Check the pre-filling pressure of the expan- sion vessel. This value must be 1.5 to 1.8 bar. To check the pressure, the outlet line of the vessel must be temporarily interrupted.

Generally:

»

Check the parameters of the water entering the system.

»

Check the conductivity of the input water and permeate with a conductivity meter.

10. DECOMISSIONING
The regular operation of the reverse osmosis unit is dependent on the continuous production of desalinated water. Even during longer periods of non- use, the system must be connected to the power supply, as hygiene regeneration is regularly carried out in standby. Keep the power and water supply of the system connected. If the system does not produce any permeate for more than 10 days, the membrane(s) must be replaced and rinsed before restarting (see chapter Initial start-up and rinsing the membrane).
10.1 Dismantling
Once the RO unit will no longer be used, dismantle (demolish or scrap) it by following the installation procedures in reverse order.
Caution: Dismantling of the unit may only be performed by qualified personnel. Electrical dismantling may only be performed by trained electricians.
Obey the safety guidelines in section “Safety Instructions,” especially the guidelines for disposal.
10.2 Disposal after dismantling
The reverse osmosis unit is made up of metal parts and plastic parts. In reference to European Union directive 2012/19/ EU issued on 4 July 2012 and the related national legislation, please note that:
The components of the electrical and electronic devices must not be disposed of as municipal waste, and therefore the method of waste separation must be applied. The public or private waste collection systems defined by local legislation must be used.
Notice: The operator is responsible for the disposal of unit components as required by law. It must be stressed that if demineralised water (manual mode) or 1-50S/cm (automatic mode) are selected, the unit will signal maintenance and cleaning via the warning only, without ever shutting down the humidifier.

The control system regulates the automatic sequence for start-up, production, process shut-down, as well as for periodic rinses by controlling the following actuators: · Feed water valve (VFEED) · Permeate flush valve (VPER) · High pressure pump (PHP) · Dosing pump Antiscalant (PASC) · Fault signal/alarm (potential-free changeover relay)
The controller is equipped with the following digital inputs for monitoring the process: · Overpressure switch (PSHIGH) · Low pressure switch (PSLOW) · Level of permeate vessel low (PSMin) · Filling level permeate vessel full ( PSMAX) · External stand-by signal (INSB) · Error dosing pump antiscalant (INPASC) · Malfunction feed water pre-filter (INFIL)
Furthermore, the controller has a conductivity measurement (not temperature compensated) for monitoring the permeate quality, with a freely adjustable limit value.
This means that the unit is switched off and a fault message is output if the limit value of the permeate conductivity is exceeded during operation.

Control 37

ENG

The different operating states
Permeate production: Production of product water. The VFEED, PHP and PASC relays are energized. STAND-BY: Unit is waiting on request. The unit is ready for operation, all relays are off. Flushing (to prevent deposits on the membrane surface): Factory activated in the main menu, flushing (when the unit is switched on), before/after water production and/or cyclically after a certain number of hours. The cyclic flushing can also be done in STANDBY mode.

Notice: Never deactivate the flushing function! (Avoidance of microbial contamination)

The production is controlled by the two level switches in the permeate tank: · PSHIGH starts the production · PSLOW stops production
In the MinPressure condition, the unit starts the water production: it opens the input solenoid valve and starts the pressure pump.
To avoid damage, a delay of 3 seconds is given after the input solenoid valve has opened.
When the MaxPressure condition is reached, the control unit goes into stand-by mode: the input solenoid valve closes and the pressure pump stops.
In the menu it is possible to deactivate one or both level switches and to operate the system with only one or no level switch at all. If both level switches are deactivated, the system goes into continuous production after switching on the power supply.
When the controller is switched on, a module flush is first carried out (if activated in menu 11).
After switching on the control system and module flushing (if activated in menu 10), the control system goes into production mode if the Min. pressure condition is underrun.
If programmed in menu 11 CLEANING the control unit starts an interval rinse during production as well as in standby (against standstill contamination) as soon as the countdown for the rinse interval has ended. The countdown for the rinse interval is reset at each rinse.

10.2 Operating states
After switching on the power supply, the version number of the control software appears for a few seconds. Then the controller returns to the last operating state before switching off.

Conductivity measurement

Permeate and feed water monitoring, alarm function included

• Specifications refer to the reference water quality: 15°C, TDS: 500 ppm, 26.7 °fH, permeat pressure: 1 bar

These values are theoretical because they can change with the temperature of the feed water and its chemical and physical qualities. These values were used for feed water with a TDS of 500 ppm and a water temperature of 18°C.

The temperature of the feed water has a great influence on the productivity and quality of the permeate. As the temperature increa- ses, the permeate output also increases, but with a worse conductivity value.

The recovery value is calculated as follows:

RECOVERY (%) = Permeate
Permeate + Concentrate*

• quantity

x 100

If a softening unit (e.g. the WaterLine-D) is connected upstream, the recovery value can increase up to 75%.

16. ANTISCALANT

Dosage specifications:
When using the recommended antiscalant Pragmaclean 309 the correct dosage depends on the ROL size and on raw water hardness, keeping constant at 30% the stroke on the dosing pump.

Notice: Use only diluted antiscalant!

How to proceed: Fill the empty canister (20l) with the quantity of antiscalant specified in the table below (l), then fill with permeate water collected from the sample tap up to full tank.
