Wa rning and safety instructions
Warning and Safety instructions
Take care when handling liquids
such as detergents, wetting agents, or neutralising agents. These may contain irritant or corrosive ingre­dients, acids or alkalis. On no account use any organic solvent, as there may be the danger of an explosion occur­ring. Follow the instructions and relevant safety procedures carefully. Wear pro­tective gloves and goggles.
Avoid inhalation of powder
cleaners. They can cause burning in the mouth and throat if swallowed, or inhibit breathing.
The water in the machine must not
be used as drinking water.
Do not sit or lean on the open door,
or rest objects on it. This could cause the machine to tip and be dam­aged.
Be careful when sorting items with
sharp pointed ends and position­ing them in the machine that you do not hurt yourself or create danger for other operators.
When using this machine in the
temperature ranges from 70 to 95°C be especially careful not to scald or burn yourself. Baskets and inserts must first cool down. Any water which may remain in containers will be very hot and must be emptied into the wash cabinet. After drying with the TA drying unit then open the door to allow the items and in­serts to cool down.

Warning and safety instructions
Warning and Safety instructions
For pre-treatment and / or cleaning
only use low-foaming detergents and disinfecting agents which have been approved by Miele. Foam can have an adverse effect on the disinfec­tion and cleaning process.
Where a chemical additive is re-
commended on technical applica­tion grounds (for example with a clean­ing agent), this does not imply that the manufacturer of the machine takes re­sponsibility for the effect of the chemi­cal on the material of the items being cleaned. Please be aware that changes in formulation, storage conditions etc, which may not be publicised by the chemical producer, 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. Only use the product for the application described by the manufac­turer, to avoid any material damage or the occurrence of strong chemical reac­tions such as oxyhydrogen.
The machine is designed only for
operation with water and additive cleaning agents. Organic solvents must not be used in the machine, as there is the danger under certain cir­cumstances of explosion. Although this is not the case with all organic sol­vents, other problems could arise with their use, for example damage to rub­ber and synthetic materials.
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 cleaning agent, quality of water are discussed with the Miele Ap­plication Technology specialists.
If the cleaning result is subject to these particularly stringent requirements (e.g. chemical analysis, specialised pro­cesses), a regular quality control test should be carried out by the user to en­sure that required standards of cleanli­ness are being achieved.
Please follow the advice on installa-
tion in these instructions and the separate Installation Instructions.
Empty any containers or utensils
before arranging them in the ma­chine.
Do not allow any remains of acids
or solvents, 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).
Ensure that solutions or steam con-
taining acid salts do not come into contact with the steel outer casing of the machine, to avoid any corrosion damage.

Warning and Safety instructions
Accessories
Use special inserts in accordance with the instructions provided.
The only accessories to be used
with the special commercial ma­chine must be those supplied or ap­proved by MIELE for the specific appli­cation. Consult your dealer or the Miele Professional department for advice.
Disposal of an old machine
When disposing of an old machine
first make it unusable. Disconnect, cut off the cable and any plug from the cable. For environmental and safety reasons ensure the machine is com­pletely drained of any residue water and cleaning agent. (Observe safety regulations and wear safety goggles and gloves). Make the door lock inoper­ative, so that children cannot acciden­tally shut themselves in. The simplest way to do this is to remove the locking pin (2 philips screws above the door). Make appropriate arrangements for the safe disposal of the machine. For tank system machines ensure that any water is emptied out of the tank.
The manufacturer cannot be held re­sponsible for any damage caused through non-observance of these Warning and Safety instructions.
In countries where there are areas
which may be subject to infesta­tion by cockroaches or other vermin, pay particular attention to keeping the machine and its surroundings in a clean condition at all times. Any dam­age which may be caused by cock­roaches or other vermin will not be covered by the machine guarantee.

Setting the water softener
Setting the water softener
To avoid the build-up of calcium de­posits on glassware and in the machine the water needs to be softened, where the supply hardness exceeds 107 ppm, (6°d).
To ensure a steady supply of soft water the water softener unit must always be:
1. correctly set
2. reactivated with "dishwasher" salt as soon as the k indicator light comes on.
The water softener must be set to corre­spond with the water hardness the time the machine is used.
Your local water authority will advise you on the water hardness in your area.

Applications and loading
Applications and loading
This laboratory glasswasher normally requires a top and a bottom basket.
Depending on the type and shape of the glassware, inserts can be supplied and there is a range of other baskets for special applications. The diversity of the inserts is so great that it is not possible to illustrate them all or give de­tailed instructions on their use here. As an example there are inserts for direct injection spraying of volumetric flasks, butyrometers, pipettes etc.
General glassware used in labora­tories, e.g. beakers, conical flasks, test tubes, etc., can be arranged in full­size, half or quarter inserts in top or bot­tom baskets. Your Miele laboratory dealer will advise on specific require­ments.
The following instructions relate only to basic preparation and loading of glass­ware.
Remove all agar residues from petri dishes.
Remove blood clots and residues from test tubes, etc.
Remove all stoppers, corks, labels, sealing wax residues, etc.
Notes
Load the glassware so that water will come into contact with all surfaces. This ensures that they will be properly cleaned.
Do not place items to be cleaned in­side other pieces where they may be concealed.
Hollow vessels such as beakers, measuring cylinders, flasks, etc. should be inverted and placed in the correct inserts. A cover net can be used to reduce the risk of movement during the wash process.
Loading the machine
Removing excess soils
Empty all glassware before loading into the machine. Take any hygiene measures necessary against infec­tion.
Ensure that no acid or solvent residues, especially hydrochloric acid or chlorides get into the wash cabinet.
Petri dishes and similar should be placed in the correct insert with the soiled side facing the centre.
Pipettes should be placed with the mouthpiece facing upwards.
Deep based items should be placed at enough of an angle for water to run off them freely.
Tall, narrow, hollow pieces should be placed in the centre of the basket to ensure good coverage of water.
Do not cover the funnel in the middle of the top basket. Mobile injector units or baskets with an adapter must engage correctly, (see below).
13
Applications and loading
Applications and loading
The spray arms must not be blocked by items which are too tall for the basket or which hang down. Rotate the arms manually to test.
Important
Make sure that the spring adapter for water connection engages correctly when a basket, injector or mobile unit is inserted into the machine. It must be 4 ­5 mm higher than the water connection inlet in the roof of the cabinet. If it is not, adjust the adapter accord­ingly.
Loosen the lock ring. Push up the adapter (4-5 mm higher
than the water connection inlet) and tighten the lock ring.

Rinsing agent
Rinsing agent
A liquid storage container incorporated in the door has a capacity of approxi­mately 200 ml. The required amount of appropriate liquid rinsing agent (e.g. Mielclear, in those countries where available), is dispensed automatically from this container.
Adding Rinsing agent
Pour rinsing agent into the storage container until the level indicator is dark (see arrow in illustration). Use a funnel if necessary.
Firmly tighten the screw cap. Clean up any spillage.
Refilling with rinsing agent
The level indicator shows how much rinsing agent is left in the container. When there is no dark colouring visible in the level indicator, the container needs to be refilled.
Setting the dosage
Undo the screw cap.
The dosage adjuster in the opening has settings from 1-6 (1-6 ml). It is set to "3" (3 ml) at the factory.
Use a higher setting if spots are left after drying.
If smearing appears, use a lower set­ting.

Wa rning and safety instructions
Warning and Safety instructions
Take care when handling liquids
such as detergents, wetting agents, or neutralising agents. These may contain irritant or corrosive ingre­dients, acids or alkalis. On no account use any organic solvent, as there may be the danger of an explosion occur­ring. Follow the instructions and relevant safety procedures carefully. Wear pro­tective gloves and goggles.
Avoid inhalation of powder
cleaners. They can cause burning in the mouth and throat if swallowed, or inhibit breathing.
The water in the machine must not
be used as drinking water.
Do not sit or lean on the open door,
or rest objects on it. This could cause the machine to tip and be dam­aged.
Be careful when sorting items with
sharp pointed ends and position­ing them in the machine that you do not hurt yourself or create danger for other operators.
When using this machine in the
temperature ranges from 70 to 95°C be especially careful not to scald or burn yourself. Baskets and inserts must first cool down. Any water which may remain in containers will be very hot and must be emptied into the wash cabinet. After drying with the TA drying unit then open the door to allow the items and in­serts to cool down.

Warning and safety instructions
Warning and Safety instructions
For pre-treatment and / or cleaning
only use low-foaming detergents and disinfecting agents which have been approved by Miele. Foam can have an adverse effect on the disinfec­tion and cleaning process.
Where a chemical additive is rec-
ommended on technical applica­tion grounds (for example with a clean­ing agent), this does not imply that the manufacturer of the machine takes re­sponsibility for the effect of the chemi­cal on the material of the items being cleaned. Please be aware that changes in formulation, storage conditions etc, which may not be publicised by the chemical producer, 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. Only use the product for the application described by the manufac­turer, to avoid any material damage or the occurrence of strong chemical reac­tions such as oxyhydrogen.
The machine is designed only for
operation with water and additive cleaning agents. Organic solvents must not be used in the machine, as there is the danger under certain cir­cumstances of explosion. Although this is not the case with all organic sol­vents, other problems could arise with their use, for example damage to rub­ber and synthetic materials.
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 cleaning agent, quality of water are discussed with the Miele Ap­plication Technology specialists.
If the cleaning result is subject to
these particularly stringent require­ments (e.g. chemical analysis, spe­cialised processes), a regular quality control test should be carried out by the user to ensure that required stand­ards of cleanliness are being achieved.
Please follow the advice on installa-
tion in these instructions and the separate Installation Instructions.
Empty any containers or utensils
before arranging them in the ma­chine.
Do not allow any remains of acids
or solvents, 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).
Ensure that solutions or steam con-
taining acid salts do not come into contact with the steel outer casing of the machine, to avoid any corrosion damage.

Reactivating the water softener
Reactivating the water softener
When the k indicator light on the left hand side of the control panel comes on during a programme the built-in water softener is depleted and cannot supply any more softened water. It must therefore be reactivated with dish- washer salt as soon as the pro­gramme has finished.
If this cannot be done immediately, and further batches have been washed, then the reactivation process must be carried out twice in succession.
Only use special course grained dish­washer salt (granule size approx. 1-4 mm), for reactivation, as other salts may contain insoluble impurities or ad­ditives which can impair the functioning of the softener.
The salt container holds approx. 2 kg salt.
Never fill the salt reservoir with dish­washer cleaning agent this can lead to – damage to the water softener and – blockage of the salt container filter insert, resulting in a build up of pressure in the salt reservoir. The irritant alkali solution could be a hazard and personal injury could be caused when the salt container is removed. Make sure that you have picked up the right packet of before filling the salt container.
dishwasher salt
Filling the salt container
Important
If the only reactivation salt available is fine grain, please consult your Miele service representative.
Reactivation salt with granules larger than 4 mm cannot be used.
Unscrew the filter insert from the salt container and remove.
Fill the salt container with granular dishwasher salt and screw the filter insert back in place.
29
Reactivating the water softener
Position the salt container as follows:
Remove the bottom basket from the machine.
Unscrew the plastic cap in the base of the wash cabinet.
Switch on the machine
Open the stopcocks if previously closed. Close the door. Press I-0. Press the k touch pad. Press the "Start" h touch pad.
The reactivation programme proceeds automatically and finishes when the indi­cator light k at the left hand side of the control panel and the "Start" indicator light h have gone out.
Then:
Switch off the machine. Unscrew the salt container carefully, so that any water pressure that has built up can be released. Do not use force. If you cannot uncrew the salt container by hand, contact the Miele Service department. Screw the plastic lid back on the socket. Reposition bottom basket. Rinse the salt container and filter in­sert thoroughly. Turn off the stopcocks if the machine is not to be used again for some time.
Place the salt container on the reacti­vation socket and screw firmly into place.
30
Important
The water pressure (flow pressure at the take off point) must be at least 2.5 bar. If it less than this see "Programming spe­cial functions".
If the flow pressure is below 2.5 bar, or if it fluctuates, the water softener can­not be reactivated in the normal way. After reactivation, salt remains may still be found in the salt container.
To use up the salt remains and to wash out the water softener, the "reactivate softener" programme must be switched on again.
Cleaning and care
Cleaning the filters in the water cabinet
The filter combination in the base of the cabinet should be inspected regularly and cleaned if necessary.

Correcting minor faults
With the aid of the following explana­tory notes, minor faults can usually be corrected without contacting the Miele Service Department. Any work on the electrical components of the machine should only be carried out by a suitably qualified and compe­tent person.
Faults/P ossib le Causes
The machine does not start
– Check that the door is properly shut. – Check the plug connection or isolator.
– Check the fuses.
A few minutes after switching on, the indicator light p q flashes.
– The stopcocks are closed. – The water inlet hose filters are dirty.
The water in the wash cabinet is not heated; the programme sequence lasts too long.
This machine has a resettable heater limiter which will switch off the heaters in the case of over-heating. This could be caused for example, if large articles obscure the heating elements or if the filters in the wash cabinet are blocked.
Remove cause of fault. Take off service panel (see under
"Electrical connection").
Switch off the machine. Open the stopcocks or clean the fil­ters (see "Cleaning and care"). Switch on the machine again and re­select the programme.
The wash cycle finishes too early and the p q indicator light flashes

Disposal of the packing material
The transport and protective packing has been selected from materials which are environmentally friendly for disposal and can normally be recycled.
Rather than just throwing these ma­terials away, please ensure they are of­fered for recycling.
Disposal of your old machine
Old machines contain materials which can be re-cycled. Please contact your local authorities or scrap merchant about potential recycling schemes, be­fore disposing of the machine.
When disposing of an old machine first make it unusable. Disconnect, cut off the cable and any plug from the cable. For environmental and safety reasons ensure the machine is completely drained of any residue water and cleaning agent. (Observe safety regulations and wear safety goggles and gloves). Make the door lock inoperative, so that children cannot accidentally shut themselves in. The simplest way to do this is to remove the lock­ing pin (2 screws above the door). Make appropriate arrangements for the safe disposal of the machine. For tank system machines ensure that any water is emptied out of the tank.
