Warning and safety instructions

6

� A damaged or leaking machine

could be dangerous. Disconnect the

machine from the mains immediately

and call the Miele Service Department.

� Personnel operating the machine

should be trained regularly. Untrained

personnel 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.

Please follow the manufacturer's safety

instructions. Wear protective gloves

and goggles. With all chemical agents,

the manufacturer's safety instructions

and safety data sheets must be

observed.

� The washer-disinfector is designed

for operation with water and

appropriate 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.

� The water in the cabinet must not be

used as drinking water.

� 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.

� Please be aware that the

washer-disinfector may be operating at

high temperatures. If the door is

opened by circumventing the lock there

is the danger of burning, scalding or

chemical burning. If disinfecting agents

are used there is 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 chemical agent

manufacturer's safety data sheets.

� Mobile units, modules, 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.

� 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.


7

� If the boiler has been programmed

to "BOILER READY", be particularly

careful of hot water and steam when

opening the door. Danger of burning or

scalding. The inlet to the wash cabinet

is located, as viewed from the unclean

side, underneath the basket runner on

the right hand side.

� Steam heating is permissible up to a

pressure of 1000 kPa (10 bar). This

corresponds to a water steam

temperature of 179°C.

� Never clean the machine or near

vicinity with a hose or a pressure

washer.

� 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 reprocessing

medical devices and sensitive

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.

� 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 for medical devices 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 must 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 are reprocessed by

thermal disinfection. Items which are

not heat-resistant, e.g. operating

theatre (OP) shoes, can be

reprocessed with the CHEM-DISIN

programme with the addition of a

chemical disinfection agent.

The range of effective disinfection is

based on claims made by the producer

of the disinfecting agent, whose advice

regarding handling, use and

effectiveness must be observed. This

type of chemo-thermal procedure is not

suitable for reprocessing medical

devices.

� Chemical agents could, under

certain conditions, 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.


8

� Do not use any abrasive chemical

agents in washer-disinfectors as these

will cause erosion to machine

components (e.g. spray arm bearings).

If using abrasive chemical agents in the

manual pre-preparation of containers or

instruments, ensure that no trace of

these remain prior to reprocessing in

the washer-disinfector.

� 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.

� The process used should be

checked regularly by the supervisor to

monitor foaming levels.

� 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 a chemical agent it is

essential that the manufacturer's

instructions are followed. The chemical

agent must only be used for the

application it is designed for and in the

situation specified, to avoid material

damage and such dangers as a severe

explosive chemical reaction (e.g. an

explosive oxyhydrogen gas reaction).

� 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 Miele.

� If cleaning and rinsing results are

subject to particularly stringent

requirements (e.g. chemical analysis),

a regular quality control test must be

carried out by the supervisor 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.

� The amount of residual solvents and

acids on items going into the cabinet

should be minimal. This applies in

particular to hydrochloric acid or

chloride solutions and to items

containing iron that can rust or corrode.

The presence in soiling of any solvents

should be minimal (especially those in

hazard class A1).


9

� 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.

� 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.

Using accessories

� Only use genuine Miele original

accessories with this washer-disinfector

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,

modules 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.

Re-usable medical devices, laboratory

equipment and accessories can be

cleaned, rinsed, disinfected and dried

in this Miele washer-disinfector.

Follow the medical device and

laboratory equipment manufacturer's

instructions (according to EN ISO

17664) and local and national

regulations and guidelines, on how to

reprocess their items by machine.

Examples of application areas:

– surgical instruments,

– minimally invasive surgical

instruments,

– anaesthetic and intensive care

instruments,

– baby bottles and teats,

– maintenance and waste containers,

– 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 reprocessed ranges from

evaporating dishes to centrifugal test

tubes.

Reprocessing medical devices and

laboratory equipment by machine

achieves reproducible results, and

should be used in preference to

reprocessing 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.

- Except for operating theatre (OP)

shoes which are not heat-resistant, for

which the CHEM-DISIN programme

should be used.

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 (CfPP 01-01, Part D and

Harmonised EU Norm EN 15883-2 in

the UK).

The cleaning programme as well as any

chemical agents must be chosen

according to the type of soiling and

load being reprocessed.

The agents used for reprocessing the

products should be selected to suit the

level of cleaning required as well as the

method of analysis used.

Intended Use

11

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 reprocessed

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

instruments and medical devices.

Examples are given in the section

"Areas of application".

The washer-disinfector is programmed

to carry out the final rinse with mains

water or processed water (e.g. Aqua

destillata, pure water, de-ionised water,

demineralised water in the quality

required by the application). The water

quality is of particular importance for

applications requiring analytically clean

laboratory glassware.

The machine qualifies for the validating

of processes in accordance with EN

ISO 15883.

User profile

Daily operatives

Operatives using the machine daily

should be familiar with the basic

functions of the machine and its loads

and trained on a regular basis. They

require basic knowledge about how to

reprocess medical devices by

machine.

Generally they would be using the

machine in Operating levels A and C.

Supervisory level

More advanced functions such as

interrupting or cancelling a programme

requires more in-depth knowledge

about machine reprocessing of medical

devices.

This level of functionality is carried out

in Operating level B.

Service and Administration

Changes to reprocessing methods and

alterations to the washer-disinfector,

e.g. concerning the type of accessories

used in it or the conditions in which the

machine is used require additional

knowledge about the machine.

Validation also requires additional

knowledge about how to reprocess

medical devices, which procedure to

use and any Standards and regulations

that may apply.

Service and validation work is carried

out using Operating level D.

Context menu

26

The automatic mobile unit recognition

system allocates a programme to a

mobile unit. The mobile units must be

coded with a magnetic strip (via a Bit

combination).

The programme allocated for a coded

mobile unit is available in operating

level C.

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.

The coding of the mobile units and

the allocation of programmes in the

Profitronic control unit are described

in the Programming manual for the

washer-disinfector.

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.

Make sure that you code mobile

units with side coupling with a track

where the sixth magnet is set to 1.

Mobile units without side coupling

must be coded with a track without

the sixth magnet.

The magnet strips for PG 8527 / PG

8528 washer-disinfectors must have

black magnets.

Automatic mobile unit recognition

27

This washer-disinfector can be fitted

with a variety of mobile units, which can

be equipped with a variety of modules

and inserts depending on the type and

shape of items requiring cleaning and

disinfection.

Select mobile units, modules 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 spray arms clean and do

they rotate freely?

– Is the flat filter clean? Remove any

coarse soiling and clean it, if

necessary.

– Is the flat filter positioned horizontally

so that it forms a flush seal with the

wash cabinet?

– Is the adapter connecting the water

supply to the spray arms/jets

correctly connected?

– Are all chemical containers

sufficiently filled?

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.

Areas of application

28

Loading the machine

– Arrange the load so that water can

access all surfaces. This ensures

that it gets 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.

– 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 mobile

units, modules and inserts to ensure

that water can flow in and out of

them unrestricted.

A cover can be used to reduce the

risk of glass breakage during the

wash process.

– 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 or being attracted by the

magnetic strip on the automatic

mobile unit recognition system.

– Deep-sided items should be placed

at an angle to make sure water runs

off them freely.

– Tall, narrow pieces should be placed

in the centre of the baskets. This

ensures good water coverage.

– Mobile units with an adapter must

engage correctly.

– Modules must be correctly

connected in the mobile unit.

– The spray arms must not be blocked

by items which are too tall or which

hang down in their path. If in doubt,

test for free movement by manually

rotating the spray arms.

– 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 cleaned and disinfected.

Disposable instruments must not

be put into the machine for

reprocessing.

For validation purposes it is

essential to follow the loading

instructions given on the template.

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, cannot get into the

wash cabinet.

Unloading instruments

Instruments should be unloaded dry

ready for further processing.


29

Surgical instruments (OP)

Surgical instruments should be stored

for as short a time as possible before

machine reprocessing - and for no

longer than 2 hours.

It is best to reprocess surgical

instruments using the DES-VAR-TD

programme.

The OXIVARIO or ORTHOVARIO

programme should be used for

instruments where there is a long delay

between the time they are used and the

time they can be reprocessed. See

"Special processes" at the end of this

booklet.

Disinfection of surgical instruments and

of those used for minimally invasive

surgery should take place thermally.

De-ionised water with a conductivity

level of ~ 15 �S/cm (microsiemens per

centimetre) should be used for the final

rinse whenever 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

a risk of corrosion.

When reprocessing narrow lumen

instruments e.g. those used in

minimally invasive surgery, an

intensive internal cleaning result is

imperative. The DES-VAR-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

reprocessed.

The final rinse must be carried out with

de-ionised water with a conductivity

level of ~15 �S/cm (microsiemens per

centimetre).

Instruments with very narrow lumen

must be manually pre-rinsed where

necessary. Follow the instrument

manufacturer's instructions on how

to handle them.

Most OP containers can be disinfected

thermally in the CONTAINER

programme. If anodised aluminium

containers are being reprocessed,

de-ionised water must be used for the

wash cycles and the final rinse.

These containers must not be

reprocessed with an alkaline cleaning

agent in a 93 °C programme with 10

minutes holding time (according to

§ 18 IfSG).

For reprocessing OP containers to an

A0=600 disinfection standard, the

CONTAINER-600 programme must be

programmed in retrospectively by

Miele.

Mobile surgical insturments and

containers are supplied with their

own operating instructions.


30

Ophthalmology

The E 929/1 mobile injector unit is

designed for the cleaning and

disinfecting of opthalmic instruments.

The final rinse should be carried out

using de-ionised water with a

conductivity of ~15 �S/cm

(Microsiemens per centimetre). In terms

of quality, the water used for the final

rinse must contain minimal amounts of

endotoxins and pyrogens.

The top level is fitted with various

connections for hollow instruments, e.g.

rinsing and suction hand pieces, and

cannulae.

Instruments are secured to the hose

connectors in the mobile injector unit

using the silicone holders and

connectors in the rack.

The lower level of the mobile injector

unit is designed to take E 441/1 inserts

or E 142 mesh trays for reprocessing

solid instruments.

Plastic fibre cover nets must not

be used in washer-disinfectors

which are used to reprocess hollow

opthalmic instruments with narrow

lumens.

The mobile injector unit for

ophthalmic instruments is supplied

with its own operating instructions.

The E 929/1 mobile injector unit

for opthalmic instruments may only

be used in washer-disinfectors

which do not have a built-in

dispensing system with a flow rate of

465 ml/min.

Washer-disinfectors fitted with

DK+WRG must not be used for

reprocessing opthalmic instruments.


31

Anaesthetic instruments (AN)

Anaesthetic instruments should be

thermally disinfected using the

DES-VAR-TD-AN programme.

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.

Mobile units for anaesthetic

instruments are supplied with their

own operating instructions.


32

Baby bottles (BC)

Baby bottles in E 135 containers can be

placed in the two lower levels of mobile

unit E 935/1 and then cleaned and

disinfected in this washer-disinfector. In

addition, E 364 containers with

wide-necked teats and E 458

containers with screw-cap teats can be

placed in the upper level of the mobile

unit.

– Ensure the level marker on the

bottles is machine-washable.

– If there is a delay of 4 hours or more

before bottles can be washed, fill

them with water to prevent residues

from drying on.

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.

Inserts for baby bottles and teats are

supplied with their own operating

instructions.

Loading in E 935/1 mobile unit

Lower level with 4 x E 135 containers

Upper level with 3 x E 135 containers

The containers must be arranged so

that the two blocked off corners are

in the positions marked with

crosses, as shown.

If bottles were to be placed in these

positions, water would not be able to

access the inside of the bottles

properly and cleaning results would

be impaired.


33

Operating theatre shoes (OS)

OP shoes made of thermolabile

material and/or insoles can be cleaned

and disinfected chemo-thermally at

60 °C with the CHEM-DISIN

programme.

A thermal disinfection process

(SHOE-TD-75/2 programme) can be

used if thermostability has been

confirmed by the manufacturer.

For reprocessing operating theatre

(OP) shoes to an A0=60 disinfection

standard, the SHOE-60 programme

must be programmed in retrospectively

by Miele.

To establish the effectiveness of

chemical disinfecting agents for

disinfection consult the manufacturer.

Theatre (OP) shoes should only be

cleaned and disinfected in a

machine installed specifically for

this purpose.

A risk evaluation should be carried

out by the user when using other

applications in addition to the

preparation of OP (Theatre) shoes in


Mobile unit E 975/1 with a suitable

insert can be used for this purpose,

e.g.

– Insert E 930 for up to shoe size 43

can be placed in the lower level of

mobile unit E 975/1,

– Insert E 931 for up to shoe size 48.

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 "Maintenance,

Cleaning the filters in the wash

cabinet".


34

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

mobile unit 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

– Petri dishes and similar should be

placed in the correct insert with the

soiled side facing the centre.

– Pipettes should be placed with the

tip facing downwards.

– Quarter inserts should be placed as

close to the middle of the unit as

possible.

– Glass items must not get in the way

of the door opening.

Preparing the load

� Empty all glassware before loading

into the machine (paying particular

attention to regulations regarding

epidemics).

Ensure that acids and residual

solvents, especially hydrochloric

acid or chlorides, cannot get into the

wash cabinet.

� 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.

� Small parts - such as stoppers and

taps - should be secured in suitable

basket inserts.

36

General notes

Problem How to resolve it

If seals, hoses and plastics in the

washer-disinfector suffer damage they

will not be water-tight and will not

function correctly.

– Establish the cause of the damage

and rectify it.

See information regarding "Chemical

agents“, "Soiling“ and "Reaction

between chemical agents and soiling“.

Heavy foaming during a programme

affects cleaning and rinsing results.

Foam escaping from the wash cabinet

can cause damage to the

washer-disinfector.

Cleaning processes cannot be

regulated and validated where there

has been a build-up of foam.

– Establish the cause of the foam and

rectify it.

– Check the process used regularly to

monitor foaming levels.




Corrosion to stainless steel in the wash

cabinet and to accessories can give

them a different appearance:

– Rust (red marks / discolouration),

– black marks / discolouration,

– white marks / discolouration (etched

surface).

Corrosive pitting can lead to the

washer-disinfector not being

water-tight. Depending on application

corrosion can influence cleaning and

rinsing results (laboratory analysis) or

cause corrosion to stainless steel items

in the cabinet.

– Establish the cause of the corrosion

and rectify it.




Chemical processes and technology

37

Chemical agents


The ingredients in chemical agents

have a strong influence on the longevity

and functionality (throughput) of the

dispensing system. The dispensing

system (hoses and pumps) should be

set up for a particular type of chemical

agent.

General types:

– alkaline to pH neutral products,

– acidic to pH neutral products,

– hydrogen peroxide.

– Observe the chemical agent

manufacturer's instructions and

recommendations.

– Carry out a regular visual check of

the dispensing system for any

damage.

– Regularly check the flow rate of the

dispensing system.

Chemical agents can damage

elastomers and plastics in the

washer-disinfector and accessories.

– Observe the chemical agent

manufacturer's instructions and

recommendations.

– Carry out a regular visual check of

any accessible elastomers and

plastics for damage.

Hydrogen peroxide can release large

quantities of oxygen.

– Only use approved processes such

as OXIVARIO or OXIVARIO PLUS.

– The wash temperature must be less

than 70 °C when using hydrogen

peroxide.

– Please contact Miele for advice.

The following chemical agents can

cause large amounts of foam to build

up:

– cleaning agents and rinsing agents

containing tensides.

Foam can occur:

– in the programme block in which the

chemical agent is dispensed,

– in the following programme block if it

has been spilt,

– in the following programme with

rinsing agent if it has been spilt.

– Process parameters in the wash

programme, such as dispensing

temperature, dosage concentration

etc. must be set to ensure the whole

process is foam free or very low

foaming.

– Please observe the chemical agent

manufacturer's instructions.


38

Chemical agents


De-foaming agents, especially silicone

based ones can cause the following:

– deposits to build up in the cabinet,

– deposits to build up on the load,

– damage to elastomers and plastics

in the washer-disinfector,

– damage to certain plastics (e.g.

polycarbonate and plexiglass) in the

load being reprocessed.

– De-foaming agents should be used

in exceptional cases only, for

instance when absolutely essential

for the process.

– The wash cabinet and accessories

should be periodically cleaned

without a load and without

de-foaming agent using the

ORGANIC programme.

– Please contact Miele for advice.

Soiling


The following substances can damage

elastomers (hoses and seals) and

plastics in the washer-disinfector:

– oil, wax, aromatic and unsaturated

hydrocarbons,

– emollients,

– cosmetics, hygiene and care

products such as creams (analytical

applications).

– Refit the washer-disinfector with oil

resistant elastomers.

– Depending on usage wipe the lower

door seal on the washer-disinfector

periodically with a lint-free cloth or

sponge.

Clean the wash cabinet and

accessories without a load using the

ORGANIC programme.

– Prepare the load using the "OIL"

programme (where this is available)

or use a special programme that

dispenses cleaning agents

containing tensides.


39

Soiling


The following substances can lead to a

heavy build-up of foam during washing

and rinsing:

– some disinfecting agents and

dishwashing detergents,

– reagents for analysis e.g. for

microtiter plates,

– cosmetics, hygiene and care

products such as shampoos and

creams (analytical applications),

– active foaming agents such as

tensides.

– Thoroughly rinse items in water

beforehand.

– Select a cleaning programme with at

least one short pre-rinse in cold or

hot water.

– Depending on application use

de-foaming agents that do not

contain silicone oils.

The following substances cause

corrosion to stainless steel in the wash

cabinet and on accessories:

– hydrochloric acid,

– other substances containing

chlorides such as sodium chloride

etc.,

– concentrated sulphuric acid,

– chromic acid,

– particles of iron and swarf.

– Thoroughly rinse items in water

beforehand.

– Place items drip dried into mobile

units, baskets and inserts and then

place these in the wash cabinet.


40

Reaction between chemical agents and soiling


Natural oils and fats can be emulsified

with alkaline chemical agents. This can

lead to a heavy build-up of foam.

– Where available use the "OIL"

programme.

– This special programme dispenses

cleaning agents containing tensides

(pH neutral) in the pre-rinse.

– Depending on application use

de-foaming agents that do not

contain silicone oils.

Soiling containing high protein levels

such as blood can cause a heavy

build-up of foam when processed with

alkaline chemical agents.

– Select a cleaning programme with at

least one short pre-rinse in cold

water.

Non-precious metals such aluminium,

magnesium and zinc can release

hydrogen when processed with very

acidic or alkaline chemical agents

(oxyhydrogen reaction).

– Please observe the chemical agent



41

Only use chemical agents

designed specifically for use in

washer-disinfectors and follow the

manufacturer's instructions on their

application.

Process validation

The standard of cleaning and

disinfection in the disinfection

programmes must be confirmed by the

user as a routine matter. In some

countries, national regulations,

guidelines and recommendations also

apply (e.g. CfPP 01-01, Part D in the

UK).

Safety checks must be carried out to

the machine every 3 months by a Miele

approved service technician in

accordance with EN ISO 15883 and

HTM 2030.

Routine checks

Before the start of each working day the

user must carry out a number of routine

checks. A check list is supplied with the

machine for this purpose.

The following need to be inspected:

– All filters in the wash cabinet

– The spray arms in the machine and

in any mobile units or modules

– The wash cabinet and the door seal

– Mobile units, modules and inserts

Maintenance

65

Cleaning the filters in the wash

cabinet

The flat filter in the wash cabinet and

the circulation pump filters prevent

coarse soiling getting into the

circulation system.

The machine must not be used

without all the filters in place.

Watch out for glass splinters,

needles etc. on the flat filter in the

wash cabinet. Danger of injury.

Cleaning the flat filter

The flat filter can become clogged with

residual soiling. It must therefore be

cleaned at least once a day.

If heavy soiling is visible at the end of a

programme cycle the flat filter must be

cleaned before starting the next

programme.

Any visible residues remaining on the

flat filter after manual cleaning can be

removed by processing in the

washer-disinfector. The exact method

depends on the layout of the mobile

unit. Contact Miele for further advice.

� Take hold of the flat filter by the

handles to remove it.

Do not pull it out by the ventilation

tubes as this can cause them to

bend and then not function

correctly.

� Soiling and deposits should be

rinsed off under running water. If

necessary a suitable soft brush can

be used.

� Then clean the flat filter using

compressed air from the underside.

� Replace the flat filter.

The flat filter must be replaced

horizontally so that it forms a flush

seal with the wash cabinet.

� Manually rotate the spray arm in the

bottom of the wash cabinet to make

sure it rotates freely.

Maintenance

66

Cleaning the circulation pump filters

There are two filters underneath the flat

filter to protect the circulation pumps.

These filters must be checked daily and

cleaned if they are soiled.

� Remove the flat filter.

� Pull the circulation pump filters up

and out of their holders, and clean

them under running water.

� Replace the circulation pump filters.

� Then replace the flat filter.

Check that all the filters have been

replaced correctly.

� Manually rotate the spray arm in the

bottom of the wash cabinet to make

sure it rotates freely.

Maintenance

67

Cleaning the spray arms

The spray arm jets can get blocked by

particles inside them.

The spray arms should, therefore, be

checked daily.

� Use a sharp pointed object to push

particles into the spray arm jets, and

rinse well under running water.

Remove the spray arms as follows:

� Take any mobile units out of the wash

cabinet.

Spray arms in the wash cabinet:

� Loosen the securing clip on the spray

arm connection and then pull the

76

Intended Use

This washer-disinfector can be set up

or retro-fitted to use the OXIVARIO

process by adding two additional

dispenser pumps together with a buffer

tank for hydrogen peroxide solution

(H2O2). The DOS 2 dispenser is used

for the H2O2 solution.

To use the ORTHOVARIO process the

DOS 4 dispensing system has to be

replaced by a dispenser pump for a

tenside based cleaning agent.

The OXIVARIO, OXIVARIO PLUS and

ORTHOVARIO programmes are

available for these requirements.

The OXIVARIO process releases active

oxygen under alkaline conditions. The

cleaning agent used must be tenside

free and have a pH value of between

11 and 11.5.

The ORTHOVARIO process uses a

special tenside based cleaning agent

in the first cleaning phase and then

releases active oxygen in the second

phase with a pH value of between 10.0

and 11.0 and a slightly higher

temperature of 65 °C.


The OXIVARIO procedure has an

alkaline main wash making it

particularly suitable for the

reprocessing of surgical instruments

where existing procedures are not

satisfactory.

It is particularly suitable for instruments

such as those used in high frequency

surgery, orthopaedic surgery as well as

for instruments which have dried out

because of the length of time between

using them and reprocessing them.

It is also suitable for antiseptic

circumstances.

The OXIVARIO PLUS process is

designed to prevent transmission of

iatrogenic prions (vCJD).

The cleaning processes are gentle

enough for instruments used in

minimally invasive surgery, including

fibre optics, where the manufacturer

has declared that they are suitable for

reprocessing with an alkaline cleaning

agent.

They are 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. Reprocessing

such items can result in colour

changes, rendering any coding on

them ineffective. If in doubt please

consult the manufacturer of the item.

Special processes - OXIVARIO and ORTHOVARIO

77

The ORTHOVARIO procedure is

suitable for reprocessing aluminium

instruments which are sensitive to

alkalines. It is particularly suitable for

orthopaedic instruments including

motor systems.

Because of its oxidising effect it

must not be used for titanium

implants, and in particular colour

coded ones.

Due to the high efficacy of the

Oxivario and Orthovario processes,

it is important to lubricate joints and

contact parts on instruments

pre-sterilisation. Please refer to the

instrument manufacturer for

guidance.

Warning and Safety

instructions

These warning and safety

instructions are in addition to those

given at the beginning of this

booklet.

� H2O2solution must only be used in

the special containers and adapters

provided by the Ecolab or Dr. Weigert

companies.

� Please observe safety instructions

(safety data sheets) provided by the

chemical agent manufacturer.

� Be especially careful when handling

H2O2 solution. It is an 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


� H2O2 solution must not be mixed

with other chemicals. This could cause

a serious chemical reaction, e. g. the

release of harmful vapours or gases.

� Only use tenside cleaning agents

supplied by Ecolab or Dr. Weigert.


78

Connecting the H2O

2solution

container

The connection hose for the H2O2

solution container is identified by a

black label. The connection hose is

supplied without a safety cap as the

container for hydrogen peroxide will

vary depending on supplier.

� Connect the supplier's safety cap to

the connection hose (black).

� Then connect this to the H2O2

solution container.

� Then start the DOS2-FILL

programme.

Unlike with other chemical agents the

H2O2 solution container must be fully

emptied before it is exchanged for a

new one.

� Do not replace the H2O2 solution

container with a new one until the Fill

DOS2 container message is

displayed. After connecting the new

container, you must run the

DOS2-FILL programme.

� If the Check dispensing system 2

message appears you should check

the container as well as the

dispensing system. The programme

will stop automatically.

Description

Washer-disinfectors fitted with a steam

condenser with heat recovery

(DK+WRG) are identified by the

following symbol.

DK+WRG variant machines can only be

used with a built-in boiler.

On these machines the steam

condenser is connected to an AD water

supply instead of to cold water. The AD

water used as a coolant flows through

the steam condenser into the boiler in


This pre-warming process reduces the

amount of energy required to heat up

water in the boiler. It also uses less

water than a steam condenser

connected to a fresh water system.

Because the water paths used in the

washer-disinfector are different the

water intake durations are longer in

those blocks that use hot AD water.


Washer-disinfectors with DK+WRG

must only be used for medical

applications.

To benefit fully from the heat recovery

system the washer-disinfector should

be operated without long pauses.

If the machine has not been

used for a longer period of time, e.g.

over a weekend the FILL BOILER

service programme must be run

before using the machine again.

For reasons of hygiene, this

programme replaces AD water from

the steam condenser and the boiler

with fresh cold AD water.

Special version with DK + WRG

80

Warning and Safety instructions

These Warning and Safety instructions are in addition

to those given at the beginning of this instruction manual.

� This washer-disinfector with DK+WRG must not be used

for reprocessing opthalmic instruments.

� With the Heat recovery system the boiler temperature of

90 °C must not be reduced. To prevent heat shock, thermally

sensitive items, e.g. fibre optic instruments should be

reprocessed using a procedure that is suitable for thermally

sensitive items. For example the last rinse before thermal

disinfection could be carried out with hot water.

� Particularly sensitive items should be checked for

suitability before reprocessing them in a programme that has

fluctuating temperature ranges.

Observe the manufacturer's instructions.
