Description of the machine

This Miele washer-disinfector is capable of cleaning a wide range of medical and laboratory products, and disinfecting them either thermally in temperatures up to 95 °C or chemo-thermally in temperatures up to 65 °C with the addition of a suitable chemical agent in accordance with general standards of hygiene and those required for the containing of epidemics. Medical products include e. g. surgical and minimally invasive instruments, instruments and utensils used in anaesthetics and intensive care, etc. Laboratory products include e.g. wide and narrow necked flasks, conical flasks, measuring cylinders, pipettes, beakers, Petri dishes etc.

Follow medical and laboratory product manufacturer's instructions on how to process their items by machine. The DESIN vario TD programme provides optimum protection for rigid fibre optics, patient systems and surgical motor systems which have been declared by their manufacturers as being suitable for machine processing. Optional drying with sterile filtered hot air is also available.

These cleaning processes use hydrogen peroxide under alkaline conditions to oxidise and remove protein soiling. The cleaning agent used must be tenside free and have a pH value of between 11 and 11.5.

The OXIVARIO procedure has an alkaline main wash making it particularly suitable for the processing of surgical instruments where existing procedures are not satisfactory and is very effective for the final stage of instrument processing.

The cleaning process is gentle enough for instruments used in minimally invasive surgery, including fibre optics, where the manufacturer has declared that they are suitable for processing with an alkaline cleaning agent.

It is not suitable for anodised aluminium. Be aware that items made from alloys containing titanium such as some implants, do not always state the material's compatibility. Processing such items can result in colour changes, rendering any coding on them ineffective. If in doubt please consult the manufacturer of the item.

This washer-disinfector is equipped to run the OXIVARIO programmes. The DOS 2 dispenser is used for the H

2O2

solution. Two special programmes are available

for this cleaning process, OXIVARIO PLUS and OXIVARIO.

Instruments processed using the OXIVARIO PLUS or OXIVARIO programmes must be very carefully handled afterwards.

Description of the machine

Areas of application:

surgical instruments,

–

with the Vario-TD programme:

–

minimally invasive instruments can be processed immediately after being used,

anaesthetic and intensive care

–

instruments, baby bottles and teats,

–

operating theatre shoes,

–

laboratory products used in research

–

and production as well as in all areas of analysis and specimen taking, including micro-biology and biotechnology.

Instruments should preferably be cleaned and then thermally disinfected using the DESIN vario TD programme. The parameters for thermal disinfection in accordance with prEN ISO 15883-1 are 80 °C (+ 5 °C, - 0 °C) with a 10 min. holding time or 90 °C (+ 5 °C, - 0 °C) with a 5 min. holding time for the inactivation of HBV.

In the U.K., reference should be made to your local infection control officer for guidelines of disinfection temperatures and holding times at temperature in accordance with HTM 2030. In Germany, the parameters for disinfection of a temperature of 93 °C, with a holding time of 10 minutes, correspond to effective areas A and B. These have been adopted into the official list for disinfection of instruments in washer-disinfectors and decontamination units, according to section 3.2 § 18 IfSG by the Robert Koch Institute (RKI) in Berlin (institute

for infectious diseases and non-communicable illnesses).

The effective areas are defined as follows: A = Suitable for the destruction of vegetative bacteria, including myco-bacteria, fungi and fungal spores. B = Suitable for inactivating viruses (including HBV and HIV).

The cleaning programme must be chosen according to the type of soiling and product requiring processing in order to ensure that disinfection is carried out correctly, no residues are left behind and that subsequent sterilisation can take place. Medical devices are best processed using the DESIN vario TD programme, or one of the OXIVARIO programmes where applicable.

This washer-disinfector is programmed to carry out the final rinse with mains water or AD water (aqua destillata = purified or de-ionised water (VE), H

pure, demineralised water, aqua purificata or distilled water where the application requires this standard). The water quality is of particular importance for applications requiring analytically clean laboratory glassware. The type of chemical agents used will depend on the analysis or analytical methods being used.

This disinfector is equipped with a steam condenser (DHK), drying unit (TA) and water softener as standard.

Optional:

- DOS 4 for retro-fitting

Correct use

Warning and safety instructions

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

The machine should be

commissioned and then maintained only by a Miele authorised and trained service technician. To ensure compliance with the Medical Devices Directive a Miele service contract is recommended. Repairs and other work by unqualified persons could be dangerous.

Do not install the machine in an

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

This washer-disinfector is designed

for specialised applications only as described in these operating instructions. Alterations or conversions to the machine, or using it for purposes other than those for which it was designed, are not permitted and could be dangerous. This machine must only be used for cleaning and disinfecting instruments or medical products and laboratory ware if the manufacturer has stated that they are suitable for machine processing. Manufacturer's cleaning and maintenance instructions for instruments etc. must also be observed. The manufacturer cannot be held liable for damage caused by improper or incorrect use of the machine.

This equipment may only be used

in mobile installations such as ships, caravans, aircraft etc. if a risk assessment of the installation has been carried out by a suitably qualified engineer.

The electrical safety of this

machine can only be guaranteed if connected to a correctly installed earthing system on site. It is most important that this basic safety requirement is tested regularly, and where there is any doubt the on-site electrical 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 machine is dangerous.

Switch off at the mains immediately and call the Miele Service Department or an authorised and trained Miele Ser vice Dealer.

Personnel operating the machine

should be trained regularly. Untrained personnel must not be allowed access to the machine or its controls. This machine is not a toy! To avoid the risk of injury never allow children to play on or near the machine, or to operate it.

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. Do not use organic solvents as these could cause an explosion. Follow all relevant safety procedures carefully. Wear protective gloves and goggles. With all chemical agents, the manufacturer's safety instructions must be observed.

The water in the machine 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 fumes. Baskets, inserts and utensils must be allowed to cool down before they are unloaded. 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.

Never clean the machine or near

vicinity with a water hose or a high pressure hose.

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 for processing medical instruments and senstitive laboratory glassware, and to avoid injury to patients or damage to equipment.

If the machine is being used for

disinfection in accordance with official regulations on the control of epidemics, the steam condenser and its connections to and from the wash cabinet must be cleaned and disinfected whenever any repairs are carried out or parts replaced.

Warning and safety instructions

For decontamination in

accordance with official regulations, the programme must not be interrupted by pressing the I-0 button to switch off after START has been pressed . Interrupting any other programmes should also be avoided as this will reduce cleaning, disinfection and the final rinse results. If it is opened the programme should be completely repeated.

The standard of cleaning and

disinfection in the disinfection programmes must be routinely confirmed by the user. The process should be regularly monitored using thermo-electrical indicators and the results should be fully documented.

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 chemo-thermal disinfection procedures is the responsibility of the operator.

If there are toxic or chemical

substances in the suds solution (e.g. aldehyde in the disinfecting agent) you must be particularly vigilant of the risks these carry should you need to interrupt a programme and open the door. The door seals and correct functioning of the steam condenser should be regularly monitored.

Theatre (OP) shoes should only be

cleaned and disinfected in a machine installed specifically for this purpose.

H2O2solution must only be used in

the special containers and adapters provided by the Ecolab and Dr. Weigert companies.

Important: observe the

manufacturer's safety instructions as given on their safety data sheet.

Be especially careful when

handling H

solution. It is an

2O2

irritant chemical. Observe all current safety instructions pertaining to its use. Wear protective gloves and goggles.

Empty containers must be

disposed of in accordance with the manufacturer's instructions.

H2O2solutions must not be mixed

with other chemicals. This could cause a serious chemical reaction, e. g. the release of harmful vapours or gases.

Warning and safety instructions

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 process.

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 and material damage.

The machine is designed for

operation with water and recommended additive chemical agents only. Organic solvents must not be used in this machine, as there is the danger under certain circumstances of fire or 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 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, modules 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.

Please follow the advice on

installation in these instructions and the separate Installation Instructions.

Warning and safety instructions

Using accessories

Only use genuine Miele

accessories with this machine. Consult Miele on the type and application of such equipment.

Only use Miele mobile units,

baskets and inserts in this machine. Using accessories made by other manufacturers, or making modifications to Miele accessories can result in unsatisfactory cleaning and disinfecting results, for which Miele cannot be held liable. Any resultant damage would also invalidate the machine guarantee.

Disposal of your old machine

Before throwing an old machine

away, it must first be made unusable. Disconnect from the mains and cut off the cable as close to the machine as possible. Please note that the machine may have contamination from blood or other bodily fluids in it and must be decontaminated before disposal. For environmental and safety reasons ensure the machine is completely drained of any residual water and cleaning agent. Observe safety regulations and wear safety goggles and gloves. Make the door lock inoperable, so that children cannot accidentally shut themselves in. Then 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 liable for damage caused by non-compliance with these Warning and Safety instructions.

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 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. 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. Important note for DESIN programmes - read the notes in the Warning and Safety instructions!

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

The water needs to be softened to avoid calcium deposits building up on instruments and utensils and in the machine itself.

To ensure a steady supply of soft water, the water softener unit must always be:

1. correctly programmed and

2. the salt reservoir must be filled. If the water hardness level is below 4 °d - German scale (0.7 mmol/l), the reservoir does not need to be filled with reactivation salt.

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

If the water supply is harder or softer than this (including below 0.7 mmol/l or 4 °d) the factory setting will need to be changed following the instructions in "Setting the water softener" in the Programming Manual.

Your local water authority will be able to advise you on the water hardness in your area.

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

Enter your water hardness level here:

°d (German scale)

or mmol/l

Setting the water softener

See "Operating information Reactivating the water softener" in the Programming Manual supplied with the machine.

Salt indicator

Reactivation salt will need to be replenished when the NO SALT indicator lights up in the display.

Reactivation takes place automatically during a programme. The programme sequence indication light REACTIVATION lights up whilst this is happening.

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

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

10.8 mmol/l).

Water softener

Filling the salt reservoir

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 wa ter which could result in damage to the water softener. If in doubt consult the Miele Professional Department.

The salt reservoir holds approx. 2.5 kg of salt.

Inadvertently filling the salt

reservoir with cleaning agent will damage the water softener. Before filling the salt reservoir make sure that you have picked up the right packet of reactivation salt.

^ Remove the bottom basket from the

machine.

Place the funnel provided in place.

^ ^ Fill carefully with salt.

As it is poured in, displaced water will run out.

^ Wipe any residual salt off the screw

threads on the socket.

^ Screw the cap on firmly.

^ Unscrew the salt reservoir cap.

Important: Before filling the salt reservoir with dishwasher salt for the first time, you must fill it with approx. 2.5 litres of water to enable the salt to dissolve. Once the dishwasher has been used, there is always sufficient water in the reservoir.

^ Select service programme REMOVE

SALT to flush out any traces of salt from the cabinet.

If, after switching on the REMOVE SALT programme, the start is delayed for a few minutes this is not a fault. The water softener is being reactivated.

Automatic mobile unit recognition (AWK)

In operating level C the (optional) AWK allocates a fixed programme place to a mobile unit with valid coding. Programme places 1-15 are reserved for the AWK automatic mobile unit recognition.

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 wash programme through which

the mobile unit is coded has to be assigned to the relevant programme place (operating level D, see the "System function - Selector Switch Organisation" section in the Programming Manual).

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). Press 6 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).

The magnetic strip on the G 7835 must have grey magnets.

Areas of application

This washer-disinfector can be fitted with a variety of mobile units, depending on the type of items being cleaned and disinfected. Various baskets and inserts are also available for a wide variety of instruments and utensils. The diversity of inserts and baskets means that it is not possible to illustrate them all or give detailed instructions on their use here.

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

– Is everything correctly

loaded/connected for cleaning?

– Are the spray arms clean and do

they rotate freely?

– Are the filters clean? Remove any

coarse soiling and clean them properly if necessary.

– Is the adapter connecting the water

supply to the spray arms/jets correctly connected?

Loading the machine

Removing excess soiling

Empty all containers before loading

into the machine (paying particular attention to regulations regarding epidemics).

Ensure that no acid or solvent

residues, especially hydrochloric acid or chlorides, get into the wash cabinet.

Preparing instruments for cleaning

^ This should preferably take place in a

dry state.

–

Are all chemical containers sufficiently filled?

Please note

Arrange the load so that water can

access all surfaces. This is to ensure that it will be properly cleaned.

Do not place items to be cleaned

inside other pieces where they may be concealed.

Hollow instruments must be

thoroughly cleaned, internally and externally.

Hollow vessels should be inverted

and placed in the correct mobile units, baskets and inserts to ensure that water can flow in and out of them unrestricted. A cover net can be used to reduce the risk of glass breakage during the wash process.

^ Please check that instruments with

long narrow hollow sections can be flushed through properly before placing them in inserts or connecting them to jets.

Lightweight items should be secured with a cover net (e.g. an A 2) and small items placed in a mesh tray to prevent them blocking the spray arms or being caught up with the magnetic strip on the automatic mobile unit recognition system.

Areas of application

Tall, narrow pieces should be placed

in the centre of the baskets. This ensures good water coverage.

Mobile units and baskets with an

adapter must engage correctly. The spray arms must not be blocked

by items which are too tall or which hang down in their path. If necessary, manually rotate the arms to test.

It is advisable to use only instruments

made of special application steel which are not susceptible to corrosion.

^ Instruments which cannot withstand

high temperatures should be chemically disinfected.

^ Disposable instruments must not be

put into the machine for processing.

Select mobile units, baskets and inserts which are appropriate for the application.

Notes on the individual areas of application and examples of loading are given on the following pages.

Deep-sided items should be placed at an angle to make sure water runs off them freely.

Areas of application

Water connection spring adapter

Make sure that the water connection spring adapter engages correctly when a basket or injector unit is inserted in the machine. It must be 4-5 mm higher than the water connection inlet in the machine. If it is not:

Loosen the lock ring.

Push up the adapter and tighten up

the lock ring.

Height adjustable top basket

The top basket can be adjusted above and below the middle position by 2 cm.

Depending on the position of the top basket and the inserts used, the baskets can accommodate vessels and instruments of the following heights:

Example: Top basket O 190/1 and bottom basket U 874

Top basket position

Top max. 20 max. 24 Middle max. 22 max. 22 Bottom max. 24 max. 20

To adjust the top basket:

^ Pull out the top basket until a

resistance is felt; lift from the runners and remove.

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

Areas of application

Laboratory glassware (LG)

Wide-necked laboratory glassware, e. g. beakers, wide-necked Erlenmeyer flasks and Petri dishes, and cylindrical shaped items e. g. test tubes, can be cleaned and rinsed, internally and externally, by the action of the rotating spray arms. They can be arranged in full, half and quarter inserts in an empty bottom or top basket with spray arms. Narrow-necked items e.g. narrow-necked Erlenmeyer flasks, conical flasks, measuring flasks and pipettes, require mobile injector units or injector modules.

The following instructions relate only to basic preparation and loading of glassware.

Loading the machine

Removing excess soiling

^ Empty all glassware before loading

into the machine (paying particular attention to regulations regarding epidemics).

Remove all stoppers, corks, labels,

sealing wax residues, etc. Small parts - such as stoppers and

taps - should be secured in suitable basket inserts.

Please note

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. Quarter inserts should be placed in

the mobile unit with at least 3 cm between them and the edge of the mobile unit.

Ensure that no acid or solvent residues, especially hydrochloric acid or chlorides, get into the wash cabinet.

Remove all agar residues from Petri dishes.

Remove blood clots and residues from test tubes, etc.

E 350 Mobile injector unit 1/1 (E 380 with connection for drying unit TA)

For narrow necked laboratory glassware with 32 (33) jets/clips.

Areas of application

Surgical instruments (OP)

Surgical instruments should be stored for as short a time as possible before machine processing.

The OXIVARIO programme is recommended for instruments where there is a long delay between the time they are used and the time they can be reprocessed.

Disinfection of surgical instruments and of those used for minimally invasive surgery should preferably take place thermally.

De-mineralised water should be used for the final rinse when possible to ensure no marks are left on the load and to avoid corrosion. If the water used contains more than 100 mg chloride/litre there is danger of corrosion.

E 327 Mobile unit/empty

For mesh trays on 2 levels

Open up hinged instruments and place them in mesh trays so that they are not touching each other.

When cleaning narrow lumen

instruments e.g. those used for minimally invasive surgery, an

intensive internal cleaning result is imperative. The Vario-TD and OXIVARIO programmes are the only ones which offer a thorough enough level of cleaning for this. It is essential that instruments are loaded as directed and that the cleaning agent used is suitable for the programme and for the sensitive instruments being processed. The final rinse must be carried out using fully demineralised water with a conductivity level of ~15 ZS/cm (microsiemens per centimeter).

E 450 Mobile injector unit

for MIS instruments (see separate Operating Instructions).

Anaesthetic equipment (AN)

Anaesthetic instruments should be thermally disinfected using the DESVAR-TD-AN programme.

If this is not possible they can be processed using a chemo-thermal programme. The water level in the machine should be increased when using a chemical disinfection programme. The standard of disinfection in chemo-thermal disinfection programmes depends on the disinfection agent used.

Areas of application

E 435/3 AN Universal mobile unit TA

If the process is not to be followed by sterilisation, the load should be dried completely to avoid the development of water-borne bacteria. A sufficient drying time is, therefore, absolutely essential.

Breathing tubes must be carefully connected and laid evenly up the spiral.

for general AN instruments (see separate Operating Instructions).

Areas of application

Baby bottles (BC)

Baby bottles can be cleaned and disinfected in one batch using 4 x E 135 containers in top basket 0 190/1 and bottom basket U 874. Wide-necked teats can be cleaned and disinfected in an E 364, or screw cap teats in an E 458 (top basket only).

Ensure the level marker on the bottles

is machine-washable. After use, if there is a delay (e.g.

4 hours or more) before washing the bottles, fill them with water to prevent residues drying on before the bottles are processed.

^ Empty the bottles before placing

them into the container.

^ Put the container lid in place over the

bottles and secure.

E 135 Insert 1/2

Container for 19 x 250 ml baby bottles

^ Place containers in the top and/or

bottom basket with the bottle necks facing downwards, and unused container corners to the outside. Containers must be placed as close to the middle of the unit as possible.

Operating theatre shoes (OS)

Polyurethane operating theatre shoes, and/or insoles should be cleaned and chemo-thermally disinfected at 60 °C. These can only be thermally disinfected (using programme SHOE-TD-75/2) if the manufacturer states that they are made of a suitably heat-resistant material.

To establish the effectiveness of chemical disinfecting agents for chemo-thermal disinfection, consult the manufacturer.

Theatre shoes should be cleaned and disinfected in a machine

installed specifically for this purpose only.

Baskets O 167, O 173 and U 168/1 are all suitable for this purpose.

Areas of application

Alternatively insert E 484 can be used in a suitable bottom basket, e. g. U 874 together with holder E 487 for shoes or E 489 for insoles.

A large amount of fluff can build up in the machine when cleaning theatre shoes. The filters in the wash cabinet should therefore be checked regularly, and cleaned when necessary. See "Cleaning and care".
