The process should be validated on a regular basis, and checked against documented control results. Chemical disinfection procedures should also be validated using chemical or bio indicators.
For thermal disinfection, use temperatures and temperature holding times to achieve the required infection prophylaxis in accordance with current health and safety regulations.
Disinfection programmes which use a chemical disinfecting agent at moderate temperatures such as 65 °C or lower are not recognised by §18 IfSG for disinfection. They should only be used for items which cannot withstand the higher temperatures used by thermal disinfection. The range of effective disinfection is based on claims made by the producer of the disinfecting agent. Their instructions on handling, use and effectiveness must be observed. The use of chemical disinfection procedures is the responsibility of the operator.
Theatre (OP) shoes should only be cleaned and disinfected in a machine installed specifically for this purpose.
Only use chemical agents formulated for special processes and approved by Miele for use with this machine. Use of unsuitable agents could adversely affect the components of the machine. 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 disinfection and cleaning result.
7
Warning and safety instructions
Foam must not be able to escape from the wash cabinet. It would hinder the correct functioning of the machine.
Check the machine regulary during use to monitor foaming.
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 agent 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 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.
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, baskets and inserts should only be used for the purpose they are designed for.
Hollow instruments must be thoroughly cleaned, internally and externally.
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).
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.

Intended Use
This washer-disinfector can be used to clean, rinse, disinfect (thermally and chemically) and dry a wide range of reusable medical devices and laboratory equipment.
Follow the manufacturer's instructions (according to EN ISO 17664) on how to process their items by machine.
Examples of application areas:
–surgical instruments,
–minimally invasive surgical instruments,
–anaesthetic and intensive care instruments,
–baby bottles and teats,
–operating theatre shoes,
or
–laboratory equipment used in research and development,
–laboratory equipment used in areas of analysis and specimen taking,
–laboratory equipment used in micro-biology and biotechnology.
The type of laboratory equipment which can be processed ranges from evaporating dishes to centrifugal test tubes.
Processing medical devices and laboratory equipment by machine achieves reproducible results, and should be used in preference to processing them by hand.
Where disinfection is required for the protection of staff and/or patients, a thermal disinfection programme, e.g. the DESIN vario TD programme, should be selected.
The parameters for thermal disinfection according to EN ISO 15883-1 (A0 concept) vary depending on the disinfection standard required. They are 80 °C (+ 5 °C, - 0 °C) with a 10 min holding time (A0 600) or 90 °C (+ 5 °C, - 0 °C) with a 5 min holding time (A0 3000). An A0 value of 3000 is suitable for deactivating the HBV virus.
National health and safety regulations regarding disinfection must also be observed.
The cleaning programme as well as any chemical agents must be chosen according to the type of soiling and load being processed.
The agents used for processing the products should be selected to suit the level of cleaning required as well as the method of analysis used.
10
Intended Use
The cleaning result must ensure that instruments can be disinfected correctly, that no residues are left behind, that subsequent sterilisation can be carried out and that the instruments can be used again safely. Medical devices are best processed using the DESIN vario TD programme, or the ORTHOVARIO or OXIVARIO programme where applicable.
The use of a suitable carrier (mobile unit, module, insert etc.) is important to ensure the adequate cleaning of the load. Examples are given in the section "Areas of application".
The washer-disinfector is programmed to carry out the final rinse with mains water or with processed water of a quality to suit the application (e.g. aqua destillata, purified water, de-ionised water, demineralised water).
This machine complies with EN ISO 15883 for validation purposes.

Opening and closing the door
Electro-thermal door lock
This machine is equipped with an electro-thermal 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 or disinfection programme is not in progress.
To open the door
Press the 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. The elements 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.
Be especially careful when using DESIN programmes - read the notes in the Warning and Safety instructions carefully.
If a great deal of hot water is present 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.

Water softener softener (Optional)
In order to achieve good cleaning results, the washer-disinfector needs to operate with soft water. Hard water results in the build-up of calcium deposits on instruments, etc, and in the washer-disinfector.
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 washer-disinfector must be programmed to correspond to the water hardness in your area.
–Your local water authority will be able to advise you on the water hardness in your area.
The water softener is set ex-works for a hardness level of 3.4 mmol/l or 19°d.
If your water hardness differs from this (even if it is below 0.7 mmol/l or 4°d) you will need to programme the level into your machine.
Where the water hardness fluctuates e.g. between 1.4 - 3.1 mmol/l (8 - 17 °d German scale) always programme the washer-disinfector to the higher value (3.1 mmol/l in this example).
The built-in water softener has settings from 1 °d - 60 °d (0.2 - 10.8 mmol/l).
For future servicing it is useful to make a note of your water hardness level.
Enter your water hardness level here:
°d 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, Operation/Reactivation).
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 softener (Optional)
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. If in doubt consult the Miele Professional Department.
The salt container holds approx. 2 kg of salt.
If only fine grained reactivation salt is available please consult the MIELE Professional Sales office for advice.
Salt with granules 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.

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.
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.

Run the reactivation programme
Close the door.
Open the stopcocks.
Select the REACTIVATION programme.
The programme will run automatically.
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 plastic cap.
Push the mobile unit back into the cabinet.
Turn off the stopcocks.
Empty the salt container. Do not empty it into the wash cabinet.
Rinse the salt container and filter insert with clean water.
The water pressure (flow pressure at the take off point) must be at least 100 kPa (1 bar).
If it is below100 kPa (1 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)
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 the 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.
20
Automatic mobile unit recognition (AWK)
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 to start the programme.
Coding is effected through 5 Bits:
–Bits 1 to 4 define the mobile unit code,
–Bit 5 serves as a control (Parity Bit).
21
Automatic mobile unit recognition (AWK)
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.

The coded total must be an even number.
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, and the mobile unit recognition function will have to 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.
Remove the magnetic strip from the track.
