Correct application

Warning and Safety instructions

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

This washer-disinfector should be

commissioned and then maintained by a Miele authorised and trained service technician only. To ensure compliance with the Medical Device Directive, a Miele service contract is recommen ded. Unauthorised repairs and other work could be dangerous, for which the manufacturer cannot be held liable.

Do not install the washer-disinfector

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

This washer-disinfector is designed

for use with the applications described in these Operating Instructions only. 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 devices if the manufacturer has stated that they are suitable for machine reprocessing. The manufacturer's cleaning and maintenance instructions for instruments etc. must also be observed. Miele cannot be held liable for damage caused by improper or incorrect use of the machine.

This washer-disinfector is intended

for stationary, indoor use only.

The electrical safety of this

washer-disinfetor can only be guaranteed if correctly earthed. It is most important that this basic safety requirement is observed 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

washer-disinfector is dangerous. Disconnect the washer-disinfector from the mains immediately and call the Miele Service Department.

Personnel operating the machine

should be trained regularly. Untrained personnel and children 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. Follow all instructions and safety procedures carefully. Wear protective gloves and goggles. With all chemical agents, the manufacturer's safety instructions and safety data sheets must be observed.

This washer-disinfector is designed

for operation with water and recommended 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, resulting in liquids leaking out of the machine.

Avoid inhalation of powder cleaners.

These cleaning agents can cause burning in the mouth and throat if swallowed and can inhibit breathing.

Please be aware that the

washer-disinfector may be operating at high temperatures. If the door is opened using the emergency release cord there is a danger of burning, scalding or chemical burning or if disinfecting agents are being used, 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.

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.

Mobile units, baskets, inserts and

the load 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.

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 hose or a pressure washer.

Warning and Safety instructions

The washer-disinfector 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 when reprocessing medical devices, in order to protect patients, and to avoid damage to the loads being cleaned.

If the washer-disinfector 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.

If it is necessary to interrupt a

programme in exceptional circumstances, this may only be done by authorised personnel.

The standard of cleaning and

disinfection in the disinfection programmes must be routinely confirmed by the user. The process must be thermo-electrically validated on a regular basis, and checked against documented control results. Chemical disinfecting 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.

Medical devices should be

reprocessed by thermal disinfection. Disinfection of other items which are not heat-resistant (e.g. operating theatre shoes) can be carried out in the CHEM 60°C-5' programme using chemical disinfection agents. 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. This type of chemo-thermal procedure is not suitable for reprocessing medical devices.

Use of chemical agents could under

certain circumstances cause damage to the washer-disinfector. Follow the recommendations of the chemical agent manufacturer. In the event of any damage or material deterioration please contact Miele.

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.

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

washer-disinfector 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".

Warning and Safety instructions

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 chemical agents such

as cleaning agent it is essential that the manufacturer's instructions are followed. Only use chemical agents for the purpose they are designed for as specified by the manufacturer, 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 cleaning agent, water quality etc. are discussed with Miele.

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.

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).

To avoid any corrosion damage,

ensure that solutions or steam containing hydrochloric acid do not come into contact with the stainless steel outer casing of the machine.

After carrying out any work on the

mains water system, the water supply system to the washer-disinfector must be vented. Otherwise, the components in the machine may become damaged.

Please follow the advice on

installation in these instructions and the separate Installation Instructions.

In areas which may be subject to

infestation by cockroaches or other vermin, pay particular attention to keeping the appliance 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 guarantee.

Empty any containers or utensils

before arranging them in the machine.

Warning and Safety instructions

Using accessories

Only use genuine Miele original

accessories with this machine and only use them for the purposes they are designed for. 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.

Only use chemical agents which

have been approved by their manufacturer for use in the application you are using. The chemical agent manufacturer is responsible for any negative influences on the material the load is made from and for any damage they may cause to the machine.

Disposing of your old machine

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, chemical residues 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.

The manufacturer cannot be held liable for damage caused by non-compliance with these Warning and Safety instructions.

Symbols on the machine

Warning: Observe the operating instructions.

Warning: Danger of electric shock.

Intended use

This washer-disinfector can be used to clean, rinse, disinfect (thermally and chemically) and dry a wide range of reusable medical devices used in doctors' surgeries and clinics. Follow the manufacturer's instructions (according to EN ISO 17664) on how to reprocess their items by machine.

Examples of application areas:

Instruments and accessories from:

anaesthetics,

–

baby bottles and teats,

–

– surgery,

– gynaecology,

– urology,

– ear, nose and throat surgery,

– ophthalmology, and

– ward-end utensils such as kidney

dishes, containers and theatre shoes.

Reprocessing instruments by machine achieves reproducible results and should be used in preference to reprocessing them by hand. Where disinfection is required for the protection of personnel and patients, carry out thermal disinfection, e.g. using the DESIN vario TD programme. Exception: thermolabile operating theatre shoes which should be reprocessed using the CHEM 60°C-5' programme. According to the A

concept of EN ISO

15883-1, thermal disinfection is achieved with the parameters 80 °C (+ 5 °C, - 0 °C) and 10 min holding time (A

600) or 90 °C (+ 5 °C, - 0 °C) and

5 min holding time (A

3000),

depending on the disinfection standard required. The effective area A

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 reprocessed.

The cleaning result must ensure that the 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 reprocessed using the DESIN vario TD programme.

The use of a suitable carrier (basket, 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).

The machine complies with EN ISO 15883 for validation purposes.

Water softener

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 °dH – 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.

Where the water hardness fluctuates e.g. between 1.4 - 3.1 mmol/l (8 17 °dH 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 °dH - 60 °dH (0.2 -

10.8 mmol/l).

Programming the water softener

Switch off the machine.

Turn the programme selector to f.

Press ß and 6 at the same time,

hold them in and, whilst doing so, switch the machine on with the I-0 switch.

The current programme status P.... will

appear in the display. The indicator light p / 6 will come on.

Press 0 once.

E01 will appear in the display.

^ Turn the programme selector one

switch position clockwise (1 o'clock position).

The number 19 will appear in the display (the factory water hardness default setting in °dH, equivalent to

3.4 mmol/l).

^ Press ß as many times as

necessary, or hold it in until the required value (degree of hardness in °dH) appears in the display.

See table on the next page for water hardness settings in °dH, mmol/l and °f.

In the event of a fault, it will help the service technician if you know the hardness of your local water supply.

Enter the water hardness below:

°dH / mmol/l

Once the number 60 has been reached, the counter will begin again at

Press 6.

SP will appear in the display.

Press 6 again.

The setting will now be stored in memory. The display will clear.

The machine is now ready for use.

Water softener

Filling the salt reservoir

Only use special coarse grained reactivation salt with granules of approx.1-4mm.Donotuseother types of salt such as cooking salt, agricultural grade or gritting salt. These may contain insoluble additives which can impair the functioning of 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.

Unscrew the salt reservoir cap.

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

Place the funnel provided in position.

Fill carefully with salt.

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

Remove the funnel and wipe any

residual salt off the seal and the screw threads on the socket.

^ Screw the cap back on firmly.

^ Run the PRE-RINSE D programme to

remove any traces of salt from the cabinet.

The programme sequence may be delayed for a few minutes after the start of the PRE-RINSE D programme. This is not a fault. The water softener is being reactivated.

Water softener

Add salt indicator

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

^ Add salt when the Add salt b k

indicator lights up.

Areas of application

This washer-disinfector normally requires a top and bottom basket. Various inserts and special baskets are also available for a wide variety of instruments and utensils.

Select 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.

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

– Is everything correctly

loaded/connected for cleaning?

– Are the lumen or necks of hollow

instruments positioned so that water can access them unhindered?

– Are the spray arms clean and do

they rotate freely?

At the end of each programme:

Carry out a visual check of the load

–

for cleanliness.

Check that all hollow shafted

–

instruments are still securely located on their jets.

Any hollow instruments that have

become disconnected from their adapters during reprocessing must be reprocessed again.

Check that the lumen of hollow

–

instruments are free of obstruction.

– Check that jets and connectors are

securely held in position in the baskets or inserts.

Protein test

Cleaning results should be subjected to periodic protein tests, e.g. with the Miele test kit.

–

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?

–

Are all chemical containers filled sufficiently?

Loading the machine

Arrange the load so that water can

–

access all surfaces. This ensures that they get properly cleaned.

Do not place items to be cleaned

–

inside other pieces where they may be concealed.

Hollow instruments must be

–

throughly cleaned, internally and externally.

Ensure that instruments with long

–

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

– Hollow vessels should be inverted

and placed in the correct baskets and inserts to ensure that water can flow in and out of them unrestricted.

– Deep-sided items should be placed

at an angle to make sure water runs off them freely.

–

Tall, narrow, hollow items should be placed in the centre of the baskets to ensure better water coverage.

–

Lightweight items should be secured with a cover net (e.g. an A 6) and small items placed in a mesh tray to prevent them blocking the spray arms.

Areas of application

It is advisable to use instruments

–

made of surgical steel only, as these are not susceptible to corrosion.

Nickel plated instruments and

–

coloured anodised aluminium instruments are not suitable for machine reprocessing.

Use the CHEM 60°C-5' and

–

combiCHEM 60°C-5' programme for instruments which cannot withstand heat.

Disposable instruments must not be

–

put into the machine for reprocessing.

Preparing the load

^ Empty all containers before loading

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

Ensure that acids and residual solvents, especially hydrochloric acid or chlorides, do not get into the wash cabinet.

Loading instruments

Contaminated instruments can be placed directly in the machine without pre-treatment (no soaking required).

–

Mobile units or 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.

Areas of application

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

Disinfection of surgical instruments and of those used for minimally invasive surgery should 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.

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

Instruments with very narrow lumen must be manually pre-rinsed where necessary. Follow the manufacturer's instructions on how to handle them.

Areas of application

Theatre shoes should be cleaned and disinfected in a machine

installed specifically for this purpose only.

If the reprocessing of theatre shoes is to be carried out in a washer-disinfector which is also to be used for other purposes, a risk assessment must be carried out by the user.

Use the following baskets:

O 167/1 for theatre shoes up to size

–

40,

– O 173/1 for theatre shoes up to size

41, and

– U 168/1 for theatre shoes up to size

45 .

Alternatively insert E 484 can be used in a suitable bottom basket, e. g. U 874/2, together with holder E 487 for shoes or E 489 for insoles.

Operating theatre shoes

Thermolabile operating theatre shoes, and/or insoles should be cleaned and chemically disinfected at 60°C (CHEM 60°C-5' programme). These can only be thermally disinfected if the manufacturer states that they are made of a suitably heat-resistant material.

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

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

Areas of application

ENT

E 373

E 417

For ear funnels and ear and nasal specula. Insert can be placed in the top or bottom basket.

^ Load the specula opened to allow all

surfaces to be accessed.

For ENT instruments, e.g. ear funnels. Insert can be placed in the top basket.

The thin chome plating on ear funnels can be very sensitive to neutralising agents.

Areas of application

GYN

E 416

Insert for gynaecology specula.

Load as shown in the illustration.

One part specula:

Place one part specula opened

between the holders.

Two part specula:

Place the lower parts in the narrow

sections of the insert, on the left of the illustration.

Place the upper parts in the wide

sections of the insert, on the right of the illustration.

Specula should always be arranged in between two holders so that they do not come into contact or cover each other.

Areas of application

Top basket/injector unit O 177/1

Left hand side of the basket: holder and 28 jets in silicone holders for the direct injection of hollow instruments. This ensures adequate cleaning and disinfection both internally and externally.

Right hand side of the basket: free e.g. for E 337 insert for upright instruments.

To minimise the risk of injury

from instruments that are sharp at each end, and when arranging instruments that have a probe pointing upwards, instruments should be loaded starting at the back and working forwards, and unloaded starting at the front and working backwards.

Endoscopy

Top basket/injector unit O 176

Right hand side of the basket: 14 holders for rigid endoscopic instruments up to 50 cm long in total.

To ensure that water can flow in and out of the hollow parts of instruments unrestricted, remove caps and seals, open valves and arrange according to the manufacturer's instructions.

Areas of application

To minimise the risk of injury

from instruments that have a probe pointing upwards, instruments should be loaded starting at the back and working forwards, and unloaded starting at the front and working backwards.

There are 10 injector jets with spring clamps for e.g. catheters or hoses on the middle axis.

The left hand side is left free for inserts, e.g. E 379.
