Description of the machine

Areas of application

This professional cleaning machine is particularly suitable for use in high-tech industrial production plants where very high reproducible standards of cleaning are required for complex items.

Areas of application include:

Electronic components such as

–

printed circuit boards and soldering frames,

Metal cleaning,

–

– Glassware cleaning,

– Decontamination of boxes and trays.

Cleaning process

This machine uses the fresh water principle. The batch time for cleaning, rinsing etc. is between 20 and 60 minutes. Drying takes place in an integrated drying unit. Drying times will vary depending on the heat retention properties of the items being processed as well as the amount of contact water left on them after cleaning. An additional drying time of between 15 - 45 minutes should be calculated. This machine can be equipped with baskets and inserts to suit the application it will be used for. Application specific programmes can also be added. Each application requires its own cleaning programme. These are not supplied as standard.

Water recovery

The IR 6002 is supplied with a two-part drainage system and a pump for recovering process water from the machine for re-use. This water must be stored in a recycling tank (not supplied) situated next to the professional cleaning machine.

This machine, together with the recycling tank as applicable, can be used as follows:

1. Fresh water system:

The whole process is carried out with fresh water. Once used the water is drained into the mains drainage system, or into a special water disposal unit.

2. Recyling the rinse water:

Water from the last two rinses, for example, is recovered and used for the cleaning and neutralising stages of the next batch. Used water from the cleaning and neutralising stages is then drained into the mains drainage system or into a special water recycling unit.

3. Recyling the cleaning water:

Used water from the cleaning stage is recovered and used for the cleaning stage of the next batch. Used water from the remaining rinse stages is then drained into the mains drainage system or into a special water recycling unit.

Correct application

Warning and Safety instructions

Please pay attention to the following notes to avoid injury and damage.

This machine should be installed,

commissioned and then maintained by a Miele authorised and trained service technician or other suitably qualified and competent approved person. Repairs and other work by unqualified persons could be dangerous. The manufacturer cannot be held liable for unauthorised work.

Do not install the machine in an area

where there is any danger of explosion or of freezing conditions.

This machine is designed for use as

described in these operating instructions only. Alterations or conversions to the machine, or using it for purposes other than those for which it is designed, are not permitted and could be dangerous. The manufacturer cannot be held liable for damage caused by improper or incorrect use or operation.

This machine is intended for land

based stationary, indoor use only. It must not be installed in mobile sites such as ships or military containers etc.

The electrical safety of this machine

can only be guaranteed if connected to a correctly installed on-site earthing system which complies with local and national safety regulations. It is most important that this basic safety requirement is present and regularly tested, and where there is any doubt, the on-site wiring system should be inspected by a qualified electrician. The manufacturer cannot be held liable for damage or injury caused by the lack of or inadequacy of an effective earthing system (e.g. electric shock).

A damaged or leaking machine is

dangerous. Disconnect the machine from the mains immediately and call the Miele Service Department.

Personnel operating the machine

should be trained regularly. Untrained personnel must not be allowed access to the machine or its controls.

Warning and Safety instructions

Take care when handling chemical

agents such as cleaning agent, neutralising agent, rinsing agent etc. These may contain irritant or corrosive ingredients. Please follow the manufacturer's safety instructions. Wear protective gloves and goggles. With all chemical agents, the manufacturer's safety instructions and safety data sheets must be observed.

The machine is designed for

operation with water and recommended additive chemical agents only. Organic solvents and flammable liquid agents must not be used in this machine. These could cause an explosion, damage rubber and plastic components in the machine, and cause liquids to leak out of the machine.

The water in the cabinet must not be

used as drinking water.

Do not sit or lean on an open door.

The machine could tip up and be damaged or cause an injury.

Be careful when sorting items with

sharp pointed ends and positioning them in the machine that you do not hurt yourself or create a danger for others. Sharp knives etc. should be placed in baskets with the pointed ends facing downwards.

When using this machine in the

higher temperature ranges, be especially careful not to scald or burn yourself or come into contact with irritant substances when opening the door. Where disinfecting agents are used there is a danger of inhaling toxic vapours.

Where there is a risk of toxic or

chemical substances occuring in the suds solution (e.g. aldehyde in the disinfecting agent), it is essential to regularly check door seals and make sure that the steam condensor is functioning correctly. Opening the machine door during a programme interruption carries particular risks in such circumstances.

Should personnel accidentally come

into contact with toxic vapours or chemical agents, follow the emergency instructions given in the manufacturer's safety data sheets.

Mobile units, modules, inserts and

the load must be allowed to cool down before unloading the machine. Any water remaining in containers could still be very hot. Empty them into the wash cabinet before taking them out.

After using the hot air drying unit,

open the door to allow the everything in the cabinet from the load itself to the mobile units, modules and inserts to cool down.

Do not touch the heating elements if

you open the door during or directly after the end of a programme; you could burn yourself. They remain hot for some time after the end of the programme.

Warning and Safety instructions

Do not clean the machine or near

vicinity with a water hose or a pressure washer.

The machine must be disconnected

from the mains electricity supply before any maintenance or repair work is carried out. Do not reconnect it until the maintenance or repair work has been successfully completed.

The following points should be observed to assist in maintaining quality standards, to protect users, and to avoid damage to the machine and items being cleaned.

Chemical agents could, under

certain conditions, cause damage to the machine. Please only use agents recommended by Miele. In the event of any damage or material deterioration please contact your Miele application specialist.

Pre-treatments with cleaning or

disinfecting agents can create foam, as can certain types of soiling and chemical agents. Foam can have an adverse effect on the cleaning process.

Foam must not be able to escape

from the wash cabinet. It would hinder the correct functioning of the machine.

Check the process used regularly to

monitor foaming levels.

To avoid the risk of damage to the

machine and any accessories used with it caused by chemical agents, soiling and any reaction between the two, please read the notes in "Chemical processes and technology".

Where a chemical additive is

recommended on technical application grounds (e.g. a cleaning agent), this does not imply that the manufacturer of the machine accepts liability for the effect of the chemical on the items being cleaned. Please be aware that changes in formulation, storage conditions etc. which may not be publicised by the chemical manufacturer, can have a negative effect on the cleaning result.

When using cleaning agents and

specialised products it is essential that the manufacturer's instructions are followed. Chemicals must only be used for the purpose they are designed for and in the situation specified, to the exclusion of other chemicals, to avoid such dangers as chemical reactions (e.g. oxyhydrogen reaction) and material damage.

In critical applications where very

stringent requirements have to be met, it is strongly recommended that all the relevant factors for the process, such as chemical agents, water quality etc. are discussed with the Miele Application Technology specialists.

Warning and Safety instructions

If cleaning and rinsing results are

subject to particularly stringent requirements (e.g. chemical analysis, specialised industrial processes etc.), a regular quality control test must be carried out by the user to ensure that the required standards of cleanliness are being achieved.

Mobile units, modules and inserts

should only be used for the purpose they are designed for.

Empty any containers or utensils

before arranging them in the machine.

Do not allow any remains of acids or

solvents, and in particular hydrochloric acid or chloride solutions, to get into the wash cabinet. Similarly avoid any materials with a corrosive effect. The presence in compounds of any solvents should be minimal (especially those in hazard class A1).

Please ensure that any water

drained into the public mains drainage system complies with all local and national water regulations. To prevent pollution to the waterways please ensure that accepted tolerance levels are adhered to.

Do not process items in this

machine if they have, for example, filings or metal shavings on them. Depending on the type and shape of filings, shavings etc. there is a risk of them causing damage to the circulation pump and also of causing contact corrosion.

Ensure that solutions or steam

containing hydrochloric acid do not come into contact with the steel outer casing of the machine, to avoid any corrosion damage.

After carrying out any work on the

mains water system, the water supply system to the machine must be vented. Otherwise, components of the machine may become damaged.

Please follow the advice on

installation in these instructions and the separate Installation Instructions.

Warning and Safety instructions

Using accessories

Symbols on the machine

Warning: Observe the operating instructions.

Warning: Danger of electric shock.

Opening and closing the door

Electric door lock

This machine is equipped with an electric door lock.

The door can only be opened when:

the electricity supply to the machine

–

is switched on,

the master switch I-0 is pressed in,

–

and

a cleaning programme is not in

–

progress.

To open the door

^ Press the 5 door button, and holding

onto the door grip open the door.

Do not touch the heating

elements if you open the door during or directly after the end of a programme: you could burn yourself. They remain hot for some time after the end of the programme.

To open the door with the emergency release

The emergency release should

only be used when the door cannot be opened normally, e.g. in the event of a power failure.

If there is a lot of hot water in the

wash cabinet when the programme is interrupted and the door is then closed quickly, hot water can escape. Danger of burning or scalding.

^ Switch the machine off with the I-0

button.

To close the door

Lift the door upwards and push until it clicks shut.

The emergency release cable is located at the bottom of the machine behind the service panel. Pull it downwards to open the door.

In order to achieve good cleaning results, the machine needs to operate with soft water. Hard water results in the build-up of calcium deposits on the load and inside the wash cabinet. Mains water with a hardness level higher than 0.7 mmol/l (4 °d – German scale) needs to be softened. This takes place automatically in the integrated water softener.

The water softener requires

–

reactivation salt.

The machine must be programmed

–

to correspond to the water hardness in your area.

Water softener

Enter your water hardness level here:

°dH or mmol/l

Setting the water softener

When the machine is first commissioned the Miele service technician has to set the machine for your local water hardness level (see Programme manual, Operating information/Reactivation).

– Your local water authority will be able

to advise you on the water hardness in your area.

The water softener unit is set at the factory for a water hardness level of 19 °dH (3.4 mmol/l).

If the water supply is harder or softer than this (including below 0.7 mmol/l or 4 °dH) the factory setting will need to be reprogrammed via the electronic controls.

For fluctuating levels, e.g.8-17°dH (1.4 - 3.1 mmol/l), set the water softener to the highest setting; in this example, to 17 °dH (3.1 mmol/l).

The built-in water softener has settings from 1 °dH - 60 °dH (0.2 -

10.8 mmol/l).

For future servicing it is useful to make a note of your water hardness level.

Reactivation display

After a certain number of cycles the message REACTIVATION will appear in the display to warn you that the water softener is depleted and cannot supply any more softened water. As soon as the programme has finished reactivation salt will need to be replenished.

If this cannot be done immediately, and further cleaning cycles have been carried out, the reactivation process will need to be carried out twice in succession.

Water softener

Reactivating the water softener

Please only use special coarse grained reactivation salt with granules of approx. 1-4 mm. Do not use other types of salt, e.g. table salt, agricultural or gritting salt. These could contain components which are insoluble in water which could result in damage to the water softener.

The salt container holds approx. 2 kg of salt.

If only fine grained reactivation salt is available please consult the Miele Spare Parts Department for advice. Salt with granules ü 4 mm must not be used in this machine.

Inadvertently filling the salt reservoir with cleaning agent can cause serious damage to the water softener and damage the filter insert, and cause pressure to build-up in the salt container. To avoid the risk of injury please exercise caution when removing the salt container as there may be irritant alkaline solutions present. Before filling the salt container make sure that you have picked up the right packet of reactivation salt.

Filling the salt container

Unscrew the filter insert from the salt

container and remove.

^ Fill the salt container with reactivation

salt and screw the filter insert back in place.

Position the salt container as follows

Remove any mobile units from the cabinet.

Unscrew the plastic cap situated in the top right-hand side of the cabinet.

There will be a small amount of

residual water in the cap. Take care as it may be hot from the previous programme.

^ Screw the salt container firmly onto

the socket.

Water softener

Then:

Switch off the machine.

Carefully unscrew the salt container,

making sure any water pressure still remaining can depressurise. Do not use force! If the container will not come off manually please contact the Miele Service Department.

Replace the cap.

Select and start the COLD WASH

programme to flush out any excess salt from the softener unit and from the cabinet.

^ Push the mobile unit back into the

cabinet.

^ Turn off the stopcocks.

^ Empty the salt container. Do not

empty it into the wash cabinet.

Run the reactivation programme

^ Close the door.

Open the stopcocks.

Select the REACTIVATION programme.

The programme will run automatically.

^ Rinse the salt container and filter

insert with clean water.

The water pressure (flow pressure at the take off point) must be at least 150 kPa (1.5 bar) for cold and hot water. If it is below150 kPa (1.5 bar) or if it fluctuates a lot, the water softener will not work properly. After reactivation, salt remains may still be found in the salt container. To use up salt remains and to rinse out the water softener, the REACTIVATION programme must be carried out again.

Automatic mobile unit recognition (AWK) (optional)

In operating level C the automatic mobile unit recognition system (AWK) allocates programme places from 1 15 to mobile units with the correct coding.

The unit coding (on the mobile unit) and the programme place with the corresponding programme (in the electronic control unit) have to match each other.

To do this:

Each mobile unit must be coded

before being used for the first time (see "Coding the mobile unit"), and

^ The programme for which the mobile

unit is coded must be allocated to t

^ he correct programme place.

See "System function - Selector switch organisation" in the Programming manual for information on how to change programme positions.

Before starting a programme it is absolutely essential that you check that the programme shown in the display is the correct one for the mobile unit being used. Otherwise inadequate cleaning or disinfection could be the result. Please make sure, that the places assigned for the programmes using Automatic mobile unit recognition are not changed around arbitrarily.

Mobile unit coding

The automatic mobile unit recognition feature assigns a programme place to a mobile unit. The mobile units must be coded with a magnetic strip (via a Bit combination). In operating level C, the only programme available for a coded mobile unit is the one assigned to the corresponding programme place.

After a coded mobile unit has been put into the machine and the door closed, the automatic mobile unit recognition system will select the allocated programme (as long as there are no residues or particles on the magnetic strip).

Make sure that there are no

small metallic objects or instrument parts attracted to the magnetic strip, in particular to the underside of it. Any metallic objects on the strip can result in the coding being incorrectly read.

Press 6 to start the programme.

Automatic mobile unit recognition (AWK) (optional)

Coding is effected through 5 Bits:

Bits 1 to 4 define the mobile unit

–

code,

Bit 5 serves as a control (Parity Bit).

–

Mobile unit coding strip

15 different codes can be set. They are assigned to programme places 1 to 15.

Under "System function, Selector switch organisation" the matching programmes have to be put into the first 15 programme places.

If the coded total gives an odd number the message CHECK MOBILE UNIT RECOGNITION appears. If the mobile unit total equals 0, the message NO MOBILE UNIT RECOGNITION will appear. In neither case can the programme be started, The mobile unit recognition function must be re-set.

Setting mobile unit coding

To set or alter the coding of a mobile unit with automatic recognition (AWK), proceed as follows:

Unscrew the track with AWK (using an allen key) and remove from the retainer.

Automatic mobile unit recognition (AWK) (optional)

Remove the magnetic strip from the

The magnetic strip must be placed in the track such that the Bit coding set out in the chart is visible through the round windows in the track.

Set the programme place coding.

Place the track in the holder in the mobile unit and screw firmly in place.

The magnetic strip must have grey magnets.

Areas of application

Cover plate

The machine is supplied with a baffle fitted in front of the hot air outlet in the rear wall of the wash cabinet. This baffle has to be dismantled if mobile units and baskets are used which have a drying unit connection on them.

^ Loosen both screws on the baffle.

Baskets

This machine can be fitted with wide variety of baskets. There are too many to describe them all here. Please contact your Miele application specialist for details of suitable baskets and inserts for your requirements, or to discuss the possiblity of having custom built ones for your particular application.

Special cleaning applications

It is possible to test particular cleaning requirements. The machine may then be used for other applications. Many users carry out their own test washes. Should the use of the machine change, then the cleaning programme can also be adapted. This applies in particular to the cleaning agents used, the type of load, and the type of soiling and material from which the items are made.

^ Take the baffle off.

Areas of application

Cleaning programmes

The machine is supplied without programmes. When creating programmes account has to be taken of the plumbing connections and any buffer or recyling tank. Consideration also has be taken of process chemicals and any physical or chemical properties of the items being cleaned and the type of soiling being handled.

The following pages give some tips on particular problems and ways of dealing with them.

If you have any questions please contact the following:

– The Miele Service Department

– Your Miele application specialist

– Your Miele Dealer

Before starting a programme you should carry out a visual check on the following:

Is everything correctly

–

Unscrew the roller bearings on both sides of the basket with a suitable spanner and reposition as required.

Areas of application

Electronics

Depending on the soldering process used and the application the products are to be used for soldering frames used in the production of electronic components and printed circuit boards can be cleaned in this machine.

Printed circuit boards

Resin or colophonium coated circuit boards can be cleaned in this machine. The results will be influenced by the type of fluxing agent used. Please seek the advice of your application specialist if required. A tenside additive is required for cleaning (0.5 - 0.7 % at 65 - 75 °C, process 1 or 2, see "Description of the machine - Water recovery") or a special cleaning agent (20% at 50 °C, process 3, see "Description of the machine - Water recovery"). If the rinse water or the special cleaning agent is to be re-used a buffer or recycling tank is required. Fully demineralised water is required for the rinse.

Fluxing agents and soldering paste

Batch times for cleaning are approx. 30 - 40 min, and approx. 30 - 50 min for drying, depending on the complexity and quantity of items being processed.

The special baskets for circuit boards, upper basket O 500 and bottom basket U 500 are made from plastic coated stainless steel. Each is designed to process 73 europa size circuit boards per batch.

Upper basket O 500

Residues from the soldering process are water soluble and must be removed. The cleaning process then takes place in water only.

Bottom basket U 500

Large quantities of small boards can be processed using inserts such as the E 402 or E 403 in conjunction with an E 439. Lightweight or sensitive circuit boards should be protected with a cover net or grille.

Areas of application

Carrying out the final rinse on aluminium soldering frames with fully demeralised water will help to prevent any material damage that might be caused by the quality of the mains water.

Example: 8 soldering frames approx. 475 mm x 430 mm x 45 - 50 mm (length x width x thickness) can be cleaned and dried in this machine in a batch time of 30 minutes, if the machine is connected to a 65 °C hot water supply.

Loading example:

Bottom basket U 874 with insert E 500

Soldering frames

Depending on the type of soiling (adipic acid, colophonium etc.) cleaning should be carried out using an alkaline cleaning agent (0.3 - 0.5% at 50 - 75 °C, process 1 or 2, see "Description of the machine Water recovery") or a special cleaning agent (1 - 3% at 50 - 75 °C, process 3, see "Description of the machine - Water recovery"). If the rinse water or the special cleaning agent is to be re-used a buffer or recycling tank is required. Depending on the type of material used to manufacture the soldering frames it may be necessary to use an acidic neutralising agent (0.1 - 0.2%) or a rinsing agent (0.05 - 0.1%).

Insert E 500

Areas of application

Metal cleaning

This machine can be used to degrease and remove any dust and lapping abrasives from metal components at the end of the manufacturing process or before they are lacquered or galvanised.

Process 1 and 2 (see "Description of the machine - Water recovery") are frequently used for this where the items are only lightly soiled with residues (0.5-1.0% cleaning agent at 60-80 °C). Process 3 (see "Description of the machine - Water recovery") is frequently used for this where the items are heavily soiled with residues (1.0-3.0% cleaning agent at 60-80 °C). If the rinse water or the special cleaning agent is to be re-used a buffer or recycling tank is required.

The cleaning agent and process used will depend on the iron, steel and non-ferrous heavy metal content. With lapping agents a test wash should be carried out to ascertain cleaning levels.

Make sure that metal shavings

(from drilling, cutting etc) cannot get into the wash cabinet. This is particularly important with corrosive iron materials.

The O 188 upper basket in conjunction with the U 874 bottom basket are recommended as standard baskets for this machine, or the 4 level E 439 for processing small components. Various mesh trays and inserts are available for processing very small items. The mesh trays and inserts can be placed in O 188/U 874 or E 439.

Depending on the material and rinse results it is often necessary to carry out a final rinse with fully demineralised water.

Glass cleaning

Technical and optical glassware can be processed in this machine to remove grease, dust and lapping abrasives and to ensure a residue free final rinse. A residue-free final result will depend on the quality of the water used. Technical advice should be sought regarding the processing of very sensitive glassware and fine grade lapping abrasives.

Process 1 and 2 (see "Description of the machine - Water recovery") are frequently used for glassware cleaning (0.5-1.0% cleaning agent at 60-80 °C). If the rinse water is to be re-used a buffer or recycling tank is required.

Baskets and inserts

Small glass lenses can be cleaned in the machine using baskets O 188/U 874 and inserts E 402/403. For larger glass lenses inserts E 118 and E 136 should be used. Small lenses can also be processed using an E 403 in an E 439.

General notes

Problem How to resolve it

If elastomers (seals and hoses) and plastics in the machine suffer damage, this can cause swelling, shrinkage, hardening and brittleness in materials and cause cracks to occur in them. They will then not function correctly. This usually takes the form of them not being water-tight.

Heavy foaming during a programme affects cleaning and rinsing results. Foam escaping from the wash cabinet can cause damage to the machine. Cleaning processes cannot be regulated and validated where there has been a build-up of foam..

Corrosion to stainless steel in the wash cabinet and to accessories can give them a different appearance:

– rust (red marks / discolouration), – black marks / discolouration, – white marks / discolouration (etched

surface).

Corrosive pitting can lead to the machine not being water-tight. Depending on application, corrosion can influence cleaning and rinsing results (laboratory analysis) or cause corrosion to stainless steel items in the cabinet.

1.7 m long terminating in a 3/4 inch female thread. On no account must the inlet filters be removed.

–

Large surface area filters should be fitted between the stopcock and the inlet hose (see "Problem solving"). The large surface area filter for AD water is made from chrome nickel steel and can be recognised by the matt top surface.

The inlet hoses must not be

shortened or damaged in any way (see illustration).

Plumbing

Drainage

The drainage system is fitted with a

–

non-return valve which prevents dirty water from flowing back into the machine via the drain hose.

The machine should preferably be

–

connected to its own drainage system on-site. If separate drainage is not available use a twin chamber siphon. The on-site drain connection point should be sited between 0.6 m and 1 m above the lower edge of the machine. If it is lower than 0.6 m lay the hose in a curve at a height of at least

0.6 m. The drainage system must be able to take a minimum drainage flow of 50 l/min.

– The drain hose is approx. 1.5 m long,

is flexible and has an internal diameter of 22 mm. It must not be shortened. Hose clips are supplied for securing it in position.

Vent at the rear

The cabinet vent at the rear of the machine has to be connected to an on-site ducting system.

–

A longer drain hose (up to 4 m long) is available to order from the Miele Spare Parts Dept.

–

The drainage system must not exceed 4 metres.
