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 processing. 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 machine may only be used in

non-stationary locations if a risk assessment of the installation has been carried out by a suitably qualified engineer.

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 Devices Directive, a Miele service contract is recommended. Unauthorised repairs could be dangerous and jeopordise the personal safety of the operator, 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.

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 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).

This washer-disinfector is intended

for indoor use only.

A damaged or leaking machine

could be dangerous and compromise your safety. Disconnect the machine from the mains immediately and call the Miele Service Department.

Warning and safety instructions

Personnel operating the

washer-disinfector should be trained regularly. Untrained personnel and children must not be allowed access to the machine or its controls.

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, and cause liquids to leak 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.

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 items should be placed in baskets with the pointed ends facing downwards.

Please be aware that the

washer-disinfector may be operating at high temperatures. If the door is opened with the emergency release cord there is a danger of burning, scalding or chemical burning.

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 condenser 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, baskets, inserts and

loads 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 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 when processing 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.

For thermal disinfection, use

temperatures and temperature holding times to achieve the required infection prophylaxis in accordance with current health and safety regulations.

Use of chemical agents could under

certain circumstances adversely affect the components of 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".

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.

Warning and safety instructions

When using chemical agents such

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.

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).

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.

Symbols on the appliance

Warning: Observe the operating instructions.

Warning: Danger of electric shock.

Intended use

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

Medical devices that can be processed in this machine include dental instruments, suction apparatus, transfer instruments, etc.

Processing instruments by machine achieves reproducible results and should be used in preference to processing 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. The parameters for thermal disinfection according to EN ISO 15883-1 (A

3000)

are 90 °C (+ 5 °C, - 0 °C) with a holding time of 5 minutes. 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 processed.

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 (optional) 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.

They are, however, essential for the correct functioning of your machine. Please do not therefore dispose of it with your general waste.

Please dispose of it at your local community waste collection / recycling centre or contact your dealer for advice. Ensure that it presents no danger to children while being stored for disposal.

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 and

the On/Off switch I-0 is pressed in.

To open the door a

Press the door release switch in as

far as it will go, and at the same time grip the handle and 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.

The door cannot be opened after a programme has been started, and it remains locked until the end of the programme. It is still possible to open the door during the PRE-RINSE D and DRAIN 6 programmes. The machine can be programmed (by a Miele approved service technician) to open during "Drying".

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 SPECIAL programmes - read the notes in the Warning and Safety instructions.

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

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).

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:

Programming the 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.

Water softener

^ 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.

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 an upper and a lower 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 processing must be re-processed.

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?

Areas of application

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.

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 processing.

Plastic items must be thermally

–

stable.

Disposable instruments must not be

–

processed in the machine.

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

Water connection spring adapter

Make sure that the spring adapter for water connection 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, adjust the adapter accordingly.

Height adjustable top basket

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

Different height items can be processed in this machine depending on the position the top basket is set at and the inserts used.

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 7mm spanner and reposition as required.

Loosen lock ring a.

Push up adaptor b.

Tighten lock ring c.

Areas of application

Upper basket/injector unit O 177/1

Left hand side of 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 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.

Upper basket/injector unit O 177/1

With E 413 insert for 6 thermally stable suction tubes (e.g. Sirona System).

Hollow instruments and tubes must be dried internally with filtered compressed air. This also ensures there are no blockages.

Dental

A special holder AUF 1 (optional extra) is required for processing hand pieces and contra angles in top basket O 177/1. Separate operating instructions are supplied with the holder.

Fibre optic hand pieces and contra angles should be monitored frequently. Those with fibre optic rods are more durable than those with fibre optic strands.

Areas of application

Care should be taken immediately after treating a patient that as little dental cement or amalgam, polishing paste etc. remains on the instruments as possible. If necessary wipe off excess with a swab. Manual cleaning can be carried out if required after thermal disinfection in accordance with national health and safety regulations.

Rhodium plated specula must be arranged in such a way that they cannot suffer mechanical damage. Not all specula with glass are suitable for machine processing.
