2. Concerning Your Safety
Agreement on Intended Uses The Pure Water System is intended exclusively for the production of pure water for in-
dustrial purposes. It must be operated within the specified conditions of operation in
rooms in which there is no danger of an explosion. All other uses of the Pure Water System are not intended uses and can lead to situations in which the System is a source of danger.
Use as intended includes observation of all the information in these instructions (es­pecially the comments on safety) and strict adherence to the specified operating conditions.
General Comments on Safety
- The Pure Water System may only be installed and operated by persons who are
familiar with the product and sufficiently qualified for the work at hand. It is up to the customer to supplement the technical documentation with instructions internal to the company in reference to supervisory and reporting obligations, work organi­sation, staff qualifications, etc.
- Before starting work at components of the Pure Water System, you must be sure
that the system has been correctly shut down as in chapter 7.2 and also secured against being started up by mistake (prevent power from being turned on, turn off the water supply and let all pressure out of the systems).
- Observe all local safety regulations in respect to:
- exposure to electric and electronic devices that draw on mains current - design of water and low pressure air systems.
- Poorly maintained air humidifier systems represent a danger to human health.
Therefore, the prescribed maintenance periods must be observed and the main- tenance work carried out correctly.
- If there is ever reason to believe that completely safe operations are no longer
possible, then the Pure Water System must be shut down at once and secured
Created: 21.09.2006 Changed: 29.02.2008 Printed: 02.03.2009 page 5 of 59
Page 6
against being started up again by mistake, and Nortec Systems should be informed. This can be the case under any of the following circumstances:
- when one or more components of the system have been damaged,
- when the system no longer works properly
- when connections or lines leak.
- The electrical system components (PerPur, DE 3-5) are IP00 protected. Take care
that they are protected against dripping and sprayed water at their locations.
CAUTION: If the System is installed in a room that has no water drain, then water sensors with automatic cut-off valves must be installed to shut off the water supply in case of damage to the system which conducts water.
- To avoid damage from water you should not store any water sensitive materials di-
rectly under system components.
- The Clear Water System may only be operated with softened water (0-1°dH, 17
ppm). Well water and rain water are not suitable. The water supply must be virtually germ free.
- If the pure water (generated by water softener and pure water system) is used for
an air humidification system, a greater or lesser amount of mineral deposits can accumulate in the vicinity of the aerosol mist. Sensitive materials and devices are to be taken away from this area or protected accordingly.
- Except for the work described in these instructions, no invasive operation of any
kind may be carried out on the Pure Water System.
- Only use original accessories and spare parts from DRAABE.
- Except with the written permission of DRAABE, no changes may be made to the
Pure Water System.
- In the event of changes to the system, an acceptance procedure is to be carried out
by the Nortec Systems customer service or other person authorized by Nortec Systems before the first start-up of the changed system.

3. Product Overview
3.1 Variants of the Pure Water System
The system is very flexible. Customer specific systems are oriented to the amount of pure water needed. All systems have a water softener and a pure water system. This two stage water treatment yields very soft water (0-1°dH, 17 ppm) which is also demineralised (95­99%).
The system variants described below just illustrate the most frequent applications. It goes without saying that each system can adapt to customer needs. Each customer receives a diagram which is only applicable to the given customer system. The customer specific con­figuration is shown in the diagram.
3.1.1 Water Softener and Clear Water System
The minimum configuration (see p. 8, view of basic system) consists of a water softener, an installation rail, a pure water system and a storage tank. These system parts form the basis of all system variants. Water circulation is completely closed; this is of great importance from the point of view of hygiene. The water produced by this basic system is primarily used for DRAABE Air Humidification or as process water for printing presses.
The water fed into the system (drinking water) is softened by the water softener (0-1°dH, 17 ppm), filtered through the two stage filter combination and, in the last treatment stage, de­mineralised by the pure water system. The pure water system also retains organic sub­stances.
The pure water system provides a remote fault indicator. The closer, in its closed state, sig­nals that there is a fault. This contact can turn an optical or acoustic transmitter on or off or can be used by the building services management system (BMS). The pure water system also organises the optimum regeneration point of the water softener.
The pure water produced by the system is stored in the storage tank (mounted on wall or standing).

3.1.2 Basic System with Pressure Boost
The working pressure of the basic system lies between 2 - 3 bar (29 – 44 psi). If the quan-
tity of pure water produced when the pressure lies in this range is insufficient, it is possible to add a pressure boost. The pressure boost (DE 3-5) increases working pressure to 3 - 5 bar (44 – 72 psi). This is useful when the consumers are at a distance or require higher in­put pressure.
The boost in pressure yields system separation between process water and the output of
the pure water system. This is especially important when the pure water is used both for printing presses and for a DRAABE air humidifier.
The pressure boost forces the pure water into a standing storage tank. There must always
be a non-return valve between the pressure boost and the standing tank so that the water in the tank cannot be forced back.
This variant is used when the pure water is to be used as process water. IMPORTANT: Further information on the performance of a pressure boost can be found in
Chapter 4, "Fundamentals of Planning".

3.1.3 Basic System with Dosing unit
The pure water produced has a hardness of 0-1°dH (17 ppm) and a conductance value of 7-30 S (dependent on the conductance of the water being processed, e.g. drinking water). Water with these values is not suitable for process water for printing presses. For an opti­mal printing result to be obtained with minimal consumption of operating materials, a hard­ness concentrate needs to be added. We recommend DRAABE hardness concentrate Aqua-Plus.
This task of adding this concentrate (additive) is carried out by the dosing unit. The dosage used is 0,5%. The result is a supply of optimally conditioned process water.
IMPORTANT: Further information can be found in chapters 4 "Fundamentals of Planning"
and in 3.2.4 "Functional Description".

3.1.4 Basic System with Air Humidification
In addition to being used as process water, the pure water can also be used for humidifica­tion of the air. With humidification there is a distinction between unitary and binary nozzle systems.
The DRAABE high pressure pulsation system (HighPur) increases the pressure to about 80 bar (1232 psi) and conducts the water to the atomizers via the high pressure ring.
Binary nozzle systems need compressed air and water. The pure water produced by the basic system with a working pressure of 2-3 bar (29-44 psi) is mixed with compressed air (working pressure around 6 bar (87 psi)) and atomized.
3.2 System Description
The DRAABE Pure Water System is a modern water treatment system which provides for a maximum of comfort and economy.
The system is built in dependence on the application and performance required. For this purpose there is a variety of system components which differ primarily in their operating data (e.g. pure water output, desalination performance). Greater performance of individual components has an influence on the selection of other system components (e.g. water sof­tener) and their installation and operation. It is possible to construct simple systems, double systems and systems with several pure water subsystems.
The following sections describe the function of the individual system components.
3.2.1 Functional Description: Installation Rail
The installation rail has several tasks. First of all, it serves as the interface between the drinking water network (company network) and the downstream water treatment system. A non-return valve makes it impossible for treated water to get back into the drinking water network.
Secondly, the water softener is bound to the installation rail (3). Various shut-off control units (2) make it possible to replace the water softener by hand (e.g. for maintenance).
A two stage filter (4, 5) protects the downstream systems. The decrease in pressure across the filters can be read from the two manometers (1, 6). Here, too, the shut-off controls make it easy to carry out a replacement if that becomes necessary (see chap. 7.2). The wa­ter pressure of the drinking water network (1) and of the filtered water (6) can be controlled continuously.
After filtration comes a hand faucet (7) via which a water sample can be drawn at any time.

3.2.2 Functional Description: Water Softener
The following description refers to the water softener type AC as well as to the water sof­tener type SoftCab 25 DR. For this description see also the drawings page 13 and 14. For new installations, solely the water softener SoftCab will be used. But for the sake of com­pleteness, the AC is described, too.
The water softener is the first stage of water treatment. It softens the water. That means that the quantity of substances in the water which are decisive in the formation of lime is very greatly reduced. A very soft water (0-1 °dH, 0-17 ppm) comes out of the exit of the wa­ter softener.
IMPORTANT: Softened water is of great importance for faultless operation of the down­stream pure water system (see section 3.2.3).
The water softener carries out its task of removing liming agents by applying the principle of ion exchange. In the water softener there are resin pellets which bind magnesium and cal­cium ions and release salt ions into the water. When a certain fixed quantity of water is treated, the resins wear out and have to be regenerated. That means the bound ions are rinsed away and exchanged for fresh salt ions. This regeneration process is fully automatic and lasts about 2 hours.
IMPORTANT: During regeneration the water supply into the downstream system is shut off!
The time of regeneration is determined by the softener type. There are two types. By the first type the pure water system controls the regeneration of the water softener (Type AC2101). A microprocessor calculates the time for the next regeneration on the basis of water consumption. When this time is reached, the microprocessor sends a signal to the AC, which automatically controls the regeneration process. When regeneration is over, the AC informs the pure water system and that system resumes its work.
The second type (SoftCab 25 DR) can be operated time- as well as quantity-controlled. For using the time-controlled mode, day and time of the regeneration have to be pre-selected. When using the quantity-controlled mode, the SoftCab calculates the time for the regenera­tion independently. When reaching the point in time for the regeneration, the water softener gives a signal to the pure water system which hereupon interrupts its production. After the process is finished, the water softener gives a release signal to the pure water system and the system continues its operation.
Salt in tablet form is required for the softening process. The water softener has a supply of salt. This supply may not fall below a certain fixed level. If it does, the water softener is no longer able to work. Since this would also cause damage to the downstream pure water system, the water softener's are equipped with a salt refill sensor. This sensor detects the lack of salt and informs the pure water system. The pure water system indicates the need for more salt on the display and then shuts itself off (further details in 3.2.3).
IMPORTANT: Only residue free tablet salt which conforms to DIN 19604 or EN 973 (no broken salt, etc.) may be used!
CAUTION: If an water softener does not use up any salt, call up Nortec Systems Customer Ser-vice at once!

3.2.3 Functional Description: Clear Water Systems (PerPur)
The Pure Water System PerPur is the heart of the water treatment system. The pure water system works by the principle of reverse osmosis and desalinates the water which has just been softened. Its output is the desalinated product (95-99% desalinated), the so called pure water permeate. This pure water can be used as is for an air humidification system or else mixed with an additive that renders it suitable for use by printing presses.
The systems are equipped with comprehensive hygiene functions. The DRAABE BioSafe System ensures hygienically faultless operation. The demanding hygienic requirements placed on a pure water system are of especially great importance when the water being pu­rified is destined for an air humidification system.
3.2.3.1 Service Recommendation
Regular maintenance, in addition to the Pure Water System's good concept, is of great im­portance for undisrupted operation which adheres to a high standard of hygiene.
Many Professional Associations advocates regular maintenance and service. DRAABE company agree that in view of the considerations given below, reverse osmosis systems must be serviced regularly.
Reverse osmosis systems work with a separating membrane. The undesirable substances in the water precipitate there and are conducted to the drain. The product (pure water) reaches the exit from the separating membrane. A separating membrane's operating prop­erties change through erosion and deposits (minerals, iron). Consequently, each separating membrane must be cleansed thoroughly after several months of operation.
With the patented DRAABE Container System this servicing procedure is easy, low cost and can be carried out without downtime in the customer's operations. Under the rental contract the customer automatically receives an exchange container every 6 to 8 months. The used container is sent back to the producer, where it is serviced. There the membrane is cleansed as required and always disinfected. Its operating data are checked and opti­mised. This service operation including disinfection is confirmed in the BG Service Book.
3.2.3.2 Certificate of Hygiene
The DRAABE Pure Water Systems are examined microbiologically for their hygiene by Fresenius Institute, which is an independent institute. The examinations are carried out at regular intervals and take place under test conditions which correspond to reality. Our sys­tems completely fulfil the requirements set by the Institute and the Professional Association for Printing and Paper Processing, which is located in Germany, Wiesbaden. Our systems work faultlessly in respect to hygiene. In an annex (section 9.3) you will find the Test Cer­tificate issued by the Fresenius Institute.

3.2.3.3 Explanation of PerPur Display
Two additional functions of the PerPur need to be explained.
The salt consumption optimisation mechanism controlled by a micro processor sees to it that the water softener is regenerated when a certain customer dependent operating time has passed. The 5 pole plug 1 (see illustration below) establishes a permanent connection between the water softener and the pure water system (see section 3.2.2).
The system has a remote fault indicator which is triggered by all malfunctions. If there is a malfunction, this can be passed via the 2 pole plug 2 to an optical and/or acoustic transmit­ter. This signal can also be sent to a building services management system.
The remote fault indicator is implemented by a voltage free closer.

Figure 7: PerPur Display
Explanation of the LED Displays:
LED Inlet pressure: The water inlet to the Clear Water System is monitored continuously. If
the water supply is disrupted, the pressure switch notices that, the sys­tem shuts itself down and the red LED lights up.
Created: 21.09.2006 Changed: 29.02.2008 Printed: 02.03.2009 page 16 of 59
Page 17
IMPORTANT: This indicator can also come if the upstream water softener is in regenera­tion mode, but then there is no malfunction, for after regeneration the system turns itself on again. If the latter does not happen, then there is, in fact, a malfunction and the remote fault indicator goes on (switch closes).
LED Operation: This green LED is always lit when pure water is being produced.
LED Tank full: The system generates pure water into a closed system. The pure wa-
ter tank (both wall and standing models) also follows this concept. A pressure switch at the exit of the pure water system indicates that the tank is full and the green LED lights up.
LED Conductance: The conductance of the pure water being produced says a lot about
the functioning of the pure water system. If the conductance leaves a certain defined range, the system is no longer working properly. For this reason, the conductance of the water being produced is monitored continuously. If the boundary value is exceeded the red LED goes on and the remote fault indicator switch closes.
LED Lack of salt: When this red LED lights up then there is no longer enough salt in the
water softener's supply container and the remote fault indicator switch closes. When the container is refilled with salt it takes about 20 min­utes for the sensor to notice that there is enough salt again.
LED Regeneration: This red LED is lit when the water softener is in regeneration mode,
and when this mode terminates the LED goes off.
LED Rinsing: With every restart, regardless of the reason for which the system
stopped, a magnetic valve ensures that the first freshly produced pure water does not flow into the tank but is directed to the drain. During this process this yellow LED is lit.
The system is equipped with a fresh water mechanism. There is a danger that stagnant
water will germinate if, after the tank has filled up (LED "Tank full" is lit), 10 hours elapse without sufficient consumption of pure water (the system has not entered operating mode). To counteract this danger, the system then goes into operating mode for a short period of time and LED "Rinsing" lights up.

3.2.3.4 Explanation PerPur 200 Display
Die pure water system PerPur 200 is equipped with an extended set of system controls. This model has all the displays and functions of the models already described. In addition it has the two additional displays and functions described below.
(1) (2) (1) LED Maintenance: This yellow LED, when lit, demands that unplanned mainte-
nance be carried out in addition to the regular service cycle of 6 to 8 months. This can happen because the separating mem­brane has been overworked and internal regulation is no longer able to set the required performance parameters.
Another possibility is that the pumping rate has fallen steeply
but this was not to be expected. When this LED lights up, the DRAABE Customer Service must
definitely be informed. The system will produce for another 14 days before it shuts itself down. When the problem is solved, the LED is turned off by a reset at the network switch.
(2) LED Pump fault: If pumping pressure reaches a fixed upper boundary value
(excessive pressure), the system shuts itself down and this red LED lights up. Please inform the DRAABE Customer Ser­vice in such a case. The LED can be turned off through a reset at the network switch.

3.2.4 Functional Description of Pressure Boost
The pressure boost system (DE) increases the output pressure of the pure water system from the range 2-3 (29-44 psi) to the range 3-5 bar (44-73 psi).
The DE can be divided into two parts. The lower part is fixed to a wall and serves as an in­terim storage tank. A float valve controls its inlet. If the interim tank is not completely full, pure water can flow into it. When the maximum water level has been reached, the valve turns the inlet off. The interim tank is equipped with a safety overflow and a drain plug.
inlet (pure water) float valve
interim storage tank safety overflow drain plug
Figure 8: Pressure Boost (lower part)
The upper part contains all the technical components for the pressure boost such as the pump and pressure switch. This part can be exchanged for maintenance or if there is a dis­ruption of service. The operator cannot and may not service or repair anything in or on this upper part. The upper part is serviced and repaired on the manufacturer's premises.
The upper part is correctly placed on the lower part (see section 8.4) and then it's just nec­essary for the plug for the voltage supply (120VAC) to be plugged into the network socket. The DE is operational as soon as its network switch (1) has been turned on. The pump, which is in the upper part, goes on when a sufficient quantity of water is present in the in­terim tank. The water level is monitored by two float valves (2). The pump forces the water from the interim store into a standing storage tank. The pump stops when a system pres­sure of 5 bar (73 psi) has been reached. The system pressure can always be read on the manometer (3). When the standing and interim tanks are full, the DE is in stand-by mode.
The system pressure goes down as water from the standing tank is used. When this pres­sure reaches 3 bar (44 psi) the DE starts boosting it again until it has risen to 5 bar (73 psi).
The switch on and switch off points are regulated by a pressure switch. In addition, the DE is equipped with a safety pressure switch (4). This switch is triggered at 6 bar (87 psi) and can only be reset mechanically (see section 7.1 for further details).

3.2.5 Functional Description of the Dosing unit
Aqua - Plus
Dosing unit
0,5%
Process water is supplied by a fully automatic, one stage dosage facility. The pure water produced by the system is mixed with 0,5% (fixed setting) of the hardening concentrate "Aqua-Plus" so as to ensure constant water hardness in the range 8°-10° dH (138-173 ppm).
CAUTION: Only use "Aqua-Plus"! Experience has shown that with other hardening concen­trates, which may not contain enough fungicides, germination of the system can set in.
The quality of the process water ought to be checked once a week. When the DRAABE hardening concentrate "Aqua-Plus" is used, this can be done with a conductance meas­urement (but not with a titration test or hardness test strip).
The following procedure should be followed when taking this measurement:
1. let the first 10 litres drain off
2. catch the next 10 litres in a clean container
3. stir thoroughly
4. measure the conductance with a calibrated device (500 – 700 µS = 8° - 10° dH (138­173 ppm)).
IMPORTANT: If a different hardness concentrate is used, ask its manufacturer which measuring method should be applied.

4. Fundamentals of Planning
The fundamentals of planning described below are theoretical. In practise, the required humidification will also be influenced by parameters which cannot be identified in this documentation. In many cases the theoretical values given here must be supplemented or corrected by values from experience. Our advisors would be glad to assist you with this.
4.1 Planning a Pure Water System
Follow the procedure below when selecting or designing the system:
- determine the needs for pure water (water for humidification, process water)
- ascertain data of the water to be treated (drinking water, company network)
- decide on a pure water system (PerPur 60/120)
- determine the need for soft water
- decide which type of water softener to use (AC/SoftCab 25 DR, WSD)
- determine the need for further devices (e.g. a dosing unit)
4.1.1 Pure Water System with Water Softener of Type AC (Air Humidification)
The following sections contain all the information required for the individual planning steps. Each step is illustrated with a computational example based on the following system data.
EXAMPLE 1
A DRAABE Pure Water System is to be installed in the paper warehouse of a printing plant for use by an air humidification system. The following data are known:
humidification rate: 57 kg/h (126 lbs/h). humidifier type: unitary nozzles, DRAABE TurboFog
raw water: hardness = 16°dH conductance = 400µS
IMPORTANT: The water data must be taken with calibrated measuring devices. Use of in­correct values during planning would have far reaching consequences.
Created: 21.09.2006 Changed: 29.02.2008 Printed: 02.03.2009 page 22 of 59
Page 23
For a humidification rate of 57 kg/h (126 lbs/h) a 120 litre system is required, that is, the PerPur 120. Here it does not matter how much of this total is to be used in which way. It could all be used for humidification or some of it could be used as process water. That does not affect the amount which passes through the water softener and wears its resins out.
To design a water softener one must understand that when pure water is produced by re­verse osmosis (this applies to all manufacturers) waste water (concentrate) is also pro­duced and this water was treated by the water softener too. To provide for this extra water, the required output rates are doubled. Also, a safety term is included for water hardness.
In our example: pure water output x 2 = 240 kg/h (530 lbs/h). Here we are using an AC 2101. It has a capacity of 100,000 litres for 1°dH. A safety term of 5°dH is added to the raw water hardness of 16°dH to yield:
total pure water output: 240 kg/h (530 lbs/h) capacity of softener: 100000 litres / (16°dH + 5°dH) = 4760 litres time before regeneration: 4760 litres / 240 litres/h = 19,8h
SOLUTION TO EXAMPLE 1
According to the foregoing example the resins must be regenerated after ~ 20 hours.
IMPORTANT: During the periods of regeneration (approx. 2 hours) no treated water is available for air humidification.
For questions about computation of humidification rates please contact DRAABE Ottawa.

4.1.2 Pure Water System with Water Softener Type SoftCab (Air Humidification and Process Water)
EXAMPLE 2
A DRAABE Pure Water System is to be installed in the paper warehouse of a printing plant for air humidification and for process water. The following data are known:
humidification rate: 57 kg/h (126 lbs/h). process water rate: 40 kg/h (89 lbs/h). humidifier type: unitary nozzles, DRAABE TurboFog
raw water: hardness = 16°dH conductance = 400µS
With a total rate of 97 kg/h (215 lbs/h) for humidification water and process water one needs a 120 litre system. A PerPur 120 is selected.
In our Example 2 we use a SoftCab 25 DR. This has a capacity of 90,000 litres for 1°dH The required output rates are doubled because of the waste water for reverse osmosis and
the raw water hardness of 16°dH is increased by a safety term of 5°dH. total pure water rate: 240 litres/h (530 lbs/h) ((= 2 x 120 litres))
capacity of softener: 90000 litres / (16°dH + 5°dH) = 4200 litres time before regeneration: 4200 litres / 240 litres/h = 17h
SOLUTION TO EXAMPLE 2
According to the foregoing example the resins must be regenerated after ~ 17 hours.
IMPORTANT: During the periods of regeneration (approx. 2 hours) no treated water is available for air humidification.
For questions about computation of humidification rates please contact DRAABE Ottawa.
4.1.3 Pure Water System with Water Softener of Type WSD
Systems with double softener (WSD) use two resin cartridges. When one of them is being regenerated the other is producing softened water. The result is a continuous, uninterrupted supply of treated water.

Page 25
Figure 11: PerPur with double softener (WSD)
EXAMPLE 2
A DRAABE Pure Water System is to be installed in the paper warehouse of a printing plant for air humidification and for process water. The following data are known:
humidification rate: 100 kg/h (220 lbs/h) process water rate: 150 kg/h (330 lbs/h) humidifier type: unitary nozzles, DRAABE TurboFog
raw water: hardness = 16°dH conductance = 400µS
With a total rate of 250 kg/h (550 lbs/h) for humidification water and process water one needs tree 120 litre system. Tree PerPur 120 are selected.
For uninterrupted water treatment, each resin cartridge must work for at least 8 hours be­fore its resins wear out and have to be regenerated. This assumption is used for the follow­ing computation of the minimum capacity required of the resin cartridges. The formula is:
WW = W x (HK + 5°dH) x 8 WW: soft water
W: water requirement ( {humidification_rate + process_water_rate} x 2 ) HK: customer dependent water hardness 5°dH: safety term 8: minimum working hours for resin cartridges
Created: 21.09.2006 Changed: 29.02.2008 Printed: 02.03.2009 page 25 of 59
Page 26
SOLUTION TO EXAMPLE 2
WW = 500 litres/h x (16°dH + 5°dH) x 8h = 84000 litres To be selected: a WSD 120 with capacity of 120,000 litres per resin cartridge.
For questions about computation of humidification rates please contact DRAABE Ottawa.
4.2 Water Supply
The DRAABE Pure Water System may only be operated with soft water. This prerequisite is fulfilled if the water is pre processed with a DRAABE Water Softener. On the other hand, well water, rain water and fully desalinated water are not allowed. As a matter of principle, the water may not contain any colloids or organic substances.
The DRAABE Air Humidification System is equipped with automatic rinsing intervals and a subsystem for keeping the water fresh so that stagnant water does not become contami­nated by germs. For these important hygienic functions to be carried out at all times, the System may not be turned off and its water supply may not be interrupted.
Processing water from reverse osmosis systems still contains a residue of salts between 1 and 5% of the original water. This minimal residue is discharged by the air humidification system into air in the room. Therefore, the air humidification system is not suitable for appli­cations for which an especially high standard for lack of particles in the room's air is re­quired (clean rooms, computing centres, etc.).
As a monopropellant jet system, the DRAABE air humidifier system places special de­mands on the water it is to atomise. It may only be operated with desalinated and virtually bacteria-free pure water.
Only treated water may be used. That means a three-stage treatment process must always be run before the water can be fed in to the HighPur.
All the following requirements in terms of water treatment are extremely important to en­sure safe, hygienic functioning. The operator shall ensure that the following requirements are met on a permanent basis. The requirements for a water treatment are met if a DRAABE pure water system is used. Of course, such systems must also be subjected to regular checking and maintenance.
A water flow pressure of 3 - 4 bar (44-58 psi) must be maintained continuously for reliable functioning of the Pure Water System to be guaranteed. The flow pressure may not exceed 4 bar (58 psi).
Created: 21.09.2006 Changed: 29.02.2008 Printed: 02.03.2009 page 26 of 59
Page 27
The following requirements are placed on the incoming raw water (drinking water):
- The water must be free of suspended particles which are larger than 5µ.
- The water must be free of colloids and organic substances.
- Well water, rain water and fully desalinated water are not acceptable
- It must meet standards for drinking water (e.g. number of organic materials)
- The maximum germ content of 1000 germs/ml may not be exceeded.
- It must have no chemical substances/additives (e.g. chlorine, ozone, disinfectants).
- No additional devices (e.g. dosing facilities) which change the properties of the in-
coming raw water may be used.
- Water temperature in the range 6 – 20 °C (43-68 °F).
- Flow pressure 3 – 4 bar (44-58 psi).
If an osmosis product of some third party is used (i.e. not a DRAABE product), then the fol­lowing values must be provided continuously by the operator:
- It must be three stage water preparation
- Water softening (<0.1 °dH at output)
- Filtering (aerosol removal filter 5u + activated charcoal filter)
- Demineralisation via reverse osmosis (inorganic membrane)
- Water values at output of water preparation
Water hardness < 0.1 °dH (< 17 ppm) Electric conductance 5-10 µS Water temperature 6-25 °C (43-77 °F) Flow pressure 2-3 bar (29-44 psi)
- No use may be made of water tanks with floating controls; rather, closed mem-
branes in stainless steel or plastic for interim storage of the product are to be used (pressure control).
- Fittings and pipes must be made of materials which are allowed in the food industry
(plastic, stainless steel). Do not use copper pipes or brass.
- The pure water must be free of organic substances.

IMPORTANT:
When the system is placed in operation, it is checked out by the DRAABE customer service technician for conformity to specifications. The technician is authorised to cancel initial op­erations if the installation is found to be erroneous.
5.4 Electrical Installation
The documentation does not cover the installation of the voltage supply. However, require­ments placed on this supply are treated. The installation of the electric components of the pure water system is shown together with the place where the voltage supply must be ap­plied.
CAUTION:
The electrical installation, including the voltage supply, must conform to all local safety regulations and standards.
IMPORTANT:
- Be sure to put the attachment cables through the cable run that is supplied.
- The cable ends are to be fitted with suitable cable end sleeves.
- Observe the values indicated for fuse protection.
- The installation may only be carried out in accordance with the diagrams gone into
here.
- During installation the voltage supply must be turned off and secured against acciden-
tal activation.
5.4.1 Water Softener
The water softener is delivered with a 12V network part and is ready to connect. For new installations, solely the water softener SoftCab will be used. But for the sake of complete­ness, the AC is described, too.
5.4.1.1 Water Softener Type AC
The type AC2101 is consumption driven. This means, that the regeneration time depends on the water consumption.
consumption driven
A consumption driven water softener (AC2101) is to be connected with the clean water sys­tem by means of the 5 pole plug delivered with it. A micro processor in the clean water sys­tem calculates the times of regeneration in dependence on water consumption and when these times are reached it sends a signal to the AC.
5.4.1.2 Water Softener Type SoftCab 25 DR
The water softener has to be connected to the pure water system by using the 5-pin-lug (in­cluded in delivery). The water softener can run both time-controlled and quantity-controlled. The time-controlled mode executes the regeneration at a fixed time. When running the quantity-controlled mode, the microprocessor of the SoftCab 25 DR calculates the point in time for the regeneration subject to the water consumption. When reaching the time for the regeneration, the SoftCab gives a signal to the pure water system. The respective mode (time- or quantity-controlled) is defined ahead of delivery. When starting up the water sof-

6. Operation
The system may not be used by the operator (customer) or some person authorised by the operator (customer) until DRAABE customer service or a person authorised by DRAABE has approved this. Also, the person operating the system must have been introduced by DRAABE to proper operation. When placing the system in operation after being instructed in its proper use, the operator (customer) is obliged to ensure that all persons who operate the system have been properly instructed. This is a condition for the DRAABE warranty.
6.1 Shutdown During Daily Operation
For maintenance work, replacement of system components which are defective or are to be serviced or in the case of malfunctioning of the system it can be necessary to turn off the system. Precisely when the system must be turned off is gone into in Chapter 8.
Complete Shutdown. Here, selected system parts or even the entire system is made volt­age free and the water supply is turned off.
PerPur: Network switch OFF (AUS). If wall socket has a switch, turn this switch off too. Shut off water inlet valves by hand.
Water Softener: Pull network part out of wall socket. Shut off water inlet valves by hand.
DE 3-5: Network switch OFF (AUS).
CAUTION: For longer shutdowns (more than 24 hours) there is a danger of germ con­tamination (automatic fresh water automatic, FWA, is not active). Before any complete shutdown (or directly afterwards) please be sure to inform DRAABE customer service.
Partial Shutdown. Here it is only necessary to prevent restart of the system while a com­ponent is being replaced.
PerPur: Shut off water inlet. The absence of pressure puts the PerPur

Page 41
6.2 Startup during Daily Operation
Depending on whether a partial or complete shutdown was carried out, the components that were turned off must be turned on again in the reverse order. As a matter of principle:
PerPur: First turn on water inlet, then establish 120VAC supply, then
turn on network switch. Water Softener: First turn on water inlet, then the voltage supply. DE 3-5: First turn on water inlet, then establish 120VAC supply, then
turn on network switch.
6.3 Checks/regular service
Regular service
PerPur: Aside from the inspections described here, the container is subject to regular service. The
operational safety as well as the hygienically clean function depend on regular service.
The manufacturer recommends a service cycle of 6 to 8 months. Service must be per­formed by the manufacturer. Only the manufacturer has special test equipment at his dis­posal, has the required knowledge to perform the necessary work and enters into a com­mitment towards the user by performing the service.
Note to purchasers (byer) of PerPur: For the duration of the 24-month warranty period, the user is obliged to comply with the above mentioned service cycle. Failure to comply may render the warranty null and void. Should a functional defect of the PerPur occur dur­ing the 24-month warranty period, warranty claims will only be accepted by Draabe, if the described service intervals for the PerPur have been complied with, i.e., if regular service has not been performed on the PerPur at max. time intervals of 8 months, the warranty of the PerPur will be rendered null and void.
Transport costs are the responsibility of the user. Service costs must be paid by the user (the user receives a report of service work performed as well as a guarantee for exchanged parts). For the time of service work (2-3 weeks) the user will receive a rental unit. The cost of the rental unit is included in the service costs.
Regular service is also recommended after the expiry of the warranty period. Note to lessees (rental) of PerPur: The manufacturer is responsible for the above men-
tioned service cycle. Transport costs for the return from the user to the manufacturer are charged the responsibility of the user. Service costs are included in the lease.
Whenever inspections reveal something suspicious or any case of incorrect functioning, the DRAABE customer service are to be notified at once! Inspection work may only be carried out by properly instructed persons. The operator (customer) is responsible for checking that the inspectors are suitable for the task and are instructed properly.

Checks
Water Softener: Check salt: Salt level should be checked regularly and the Wa-
ter Softener refilled as required (see page 13).
Cycle: every two days
Dosing unit: Check Aqua-Plus: The Aqua-Plus level should be checked
regularly and the container replaced as appropriate.
Cycle: once a weeks
6.3.1 Installation Rail (pressure lost, pressure reducer filters)
The water softener's input pressure and output pressure (i.e. PerPur input pressure) can be read at the two manometers. The difference indicates the pressure lost in the water sof­tener, the filter of the pressure reducer and the two cartridge filters. If, as is assumed here, the water softener is working properly, then this pressure difference just indicates the condi­tion of the filters. The more material that these filters have filtered out, the greater the loss of water pressure.
When this difference, or pressure loss, exceeds 0.9 bar (13.5psi), the filter of the pressure reducer must be cleaned (1) and/or the filters (4, 5) must be replaced. In this case please get in touch with your Nortec Systems Customer Service.
Cycle: once a weeks
6.3.2 Storage Tank (initial pressure)
Valve where the pressure meatering device has to be connected.
The initial pressure of the storage tank can be checked with a pressure measuring device. Then the tank must be completely empty. The pressure must be 0.7 bar (10 psi).
Cycle: every 6 months

6.4 Consumables
6.4.1 Salt in Water Softener
The water softening process requires salt in tablet form. If the salt supply in a Water Sof­tener has been consumed, then salt must be refilled. For this, take off the blue covering and then the white cover underneath it. Refill with a new package of salt (25kg) and put the cover and covering back on the water softener (see page 13).
IMPORTANT:
Only residue free tablet salt as in DIN 19604 or EN 973 (no broken salt, etc.) may be used!
IMPORTANT:
If no consumption of salt is established, inform Nortec Systems Customer Service at once! This case could indicate a mal function.
6.4.2 Filter of the installation rail
For each regular servicing of the pure water system the filters of the installation rail must be replaced. These are delivered with the exchange container. If there is a severe drop in pressure or any discolouration during operation, contact Nortec Systems Customer Service.
6.4.3 Aqua-Plus
Aqua-Plus is not a hazardous substance as defined by chemicals legislation and EU Direc­tive 67/548/EEC; however, when it is not properly handled it still constitutes a threat to hu­man beings and the environment. In addition to the safety measures listed below the re­gionally applicable safety measures for handling chemicals should be observed:
- Avoid all contact with the eyes and any longer contact with the skin.
- Change any contaminated clothing immediately. Preventive skin protection is neces-
sary. When work is over wash hands and face.
- Do not allow Aqua-Plus to get into the sewage system or the ground.
- To remove Aqua-Plus, use material that binds water. Rinse away small amounts with
water.
- Aqua-Plus should be stored in an airtight, leak-proof container at 10 to 25°C (50 to
77°F).

According to paragraph 10 of the German Ordinance on Pressure Vessels (DruckBehV), recurrent tests are to be carried out on pressure vessels (inner and pressure test). Type and scope of test depend on which of various groups the vessel belongs to:
Groups II and III: Recurrent tests by an expert. The time intervals between tests are deter-
mined by the operator.
Group IV: Recurrent tests by an expert.
outer test: every 2 years inner test: every 5 years

Test objects:
Product description: Air humidification system Model: PUR
Appliances tested : DRAABE pure water system PerPur, SynPur
DRAABE high pressure system HighPur DRAABE air humidification system Turbo Fog (TF4, TF16, TF32
DI Flex (ED/HT), BS
Test period:
The DRAABE appliances that are listed as "tested appliances" were microbiologically tested by us in 2005 over a period of 6 months. Microbiological check studies are carried out on the system at regular intervals to also confirm the results in the long term.
Test conditions and requirements:
The system must permanently prove that it permanently functions hygienically as part of this study. In this process the test conditions assume the "worst case". This is the case if:
- the entire system is in standby mode
- no air humidification is demanded
- the room air does not require any conditioning in terms of the humidity (% air humidity)
The hygiene levels must ensure the maintenance of the following requirements during the entire test period (3% humidification EIN). Pro­cedures were not employed which cause the additional discharge of chemicals /biocides in the room air.
The system was contaminated with a germ compound three times in the course of the test. The system configuration corresponded to the maximum extension level of the DRAABE system (see above). The results shall be stated by means of a detailed analysis report.
Contents of the analysis report:
Materials tested, description of the test, test bacteria, contamination interval, germ pollution, individual results, composition and quantity of the germ compound (for the contamination process).
Results: The DRAABE system tested by us completely fulfils the aforementioned requirements. As a result the requirements for the
awarding of the INSTITUT FRESENIUS quality seal have been fulfilled. The DRAABE system that was tested works perfectly in terms of the hygiene levels and fulfils the present demands (as at: December 2005) of BG Druck und Papierverarbeitung, Wies­baden.
The following total germ levels were not exceeded:
Admission water air humidification KBE*/ml Humidifier water KBE*/ml
The evaluation of the test result is based on the data of a system operating in accordance with the operating instructions drafted by DRAABE and their service intervals.
