Safety Instructions and Warnings

6

� A damaged or leaking

washer-disinfector is is a hazard to your

safety. Immediately turn off the

washer-disinfector at the power switch

and contact the Miele Service

Department.

� Washer-disinfector operators must

be trained on a regular basis. Untrained

personnel must not be allowed access

to the washer-disinfector or its controls.

� Always exercise caution when

handling the processing chemicals for

this washer-disinfector (detergent,

neutralizer, saponifier, rinsing agent,

etc.). These products can cause

irritation and burning.

Comply with the applicable safety

regulations! Use protective eyewear

and gloves. Always follow the

manufacturer's safety

recommendations when using process

chemicals (see material safety data

sheets).

� The washer-disinfector is designed

for use with water and designated

processing chemicals only. The

washer-disinfector must not be

operated with organic solvents or

flammable liquids. This may cause an

explosion or damage to rubber and

plastic components, which in turn

allows liquid substances to leak out.

� The water in the wash chamber is

NOT safe to drink.

� Take care when sorting items with

sharp, pointed ends. Position them in

the washer-disinfector so that you will

not hurt yourself or create a danger for

others.

� When operating this

washer-disinfector, beware of the high

temperatures involved. If you bypass

the electrical lock to open the door,

there is the danger of scalding and

heat or chemical burns. If disinfectants

have been used, there is also the

danger of inhaling toxic vapour.

� The door seal and the operation of

the steam condenser should be

regularly checked, as volatile toxic or

chemical substances (e.g. aldehyde in

the disinfection agent) may be created

in the wash water during preparation.

Opening the door of the

washer-disinfector during a program

interruption therefore poses a major

risk.

� If you are exposed to toxic vapours

or processing chemicals, consult the

chemical manufacturer's material safety

data sheets for emergency procedures.

� Always allow mobile units, modular

baskets, inserts, and loads to cool

before removing. Be sure to empty any

water from concave items into the wash

chamber before removing.

� After drying with the drying unit,

leave the door open at first, to allow the

items and inserts to cool down.

� If the boiler has been programmed

to "BOILER READY", always beware of

hot water and steam when opening the

door! Looking from the unclean side,

the inlet pipe is located beneath the

right basket guide rail.

� Steam heating is permissible up to a

pressure of 1000 kPa (10 bar). This

corresponds to a water steam

temperature of 179°C.


7

� Do NOT hose down the

washer-disinfector or the immediate

vicinity, e.g., with a water hose or

pressure washer.

� Before servicing the

washer-disinfector, disconnect it from

the power supply.

The following points should be

observed, to assist in maintaining

quality standards when processing

medical devices and critical labware,

to protect patients, and to avoid

damage to property!

� If the washer-disinfector is being

used for disinfection ordered by the

authorities, the steam condenser and

its connections to the rinsing chamber

and outlet discharge must be

disinfected before any repair or

exchange.

� Only authorized persons may

interrupt a program, and only in

exceptional cases.

� It is the responsibility of the operator

to routinely check that the required

cleaning and disinfection standards for

medical devices are being met.

Therefore, process results have to be

regularly tested and documented, both

thermo-electrically and through

inspection. For thermochemical

processes, additional testing is

required using chemical or biological

indicators.

� For thermal disinfection, the

appropriate temperatures and holding

times, as required by microbiological

and public health standards and

guidelines, must be used to achieve the

required degree of infection control.

� The processing of medical devices

is carried out by means of thermal

disinfection.

The disinfection of other items that are

not heat-resistant (e.g. OR shoes) can

be carried out using the CHEM-DESIN

program with the addition of a chemical

disinfectant.

The disinfection parameters are based

on the recommendation of the

disinfectant manufacturer. Always

observe their specifications for

handling, applications and efficacy.

These chemo-thermal processes are

not suitable for processing medical

devices.

� Under certain circumstances, the

process chemicals can cause damage

to the washer-disinfector. It is

recommended to follow the

recommendations of the process

chemical manufacturers. In the event of

damages or concerns about possible

material incompatibilities, please

consult Miele.

� Do not use any abrasive process

chemicals with the washer-disinfector.

They increase the wear on machine

components (e.g. spray arm supports).

If such agents are used for manual

pre-treatment of containers or

instruments, they must be completely

removed before placing the items in the

washer-disinfector!


8

� Pre-treating (e. g. with cleaning

agents or disinfectants), some types of

soiling and the interaction of certain

processing chemicals can cause

foaming. Suds can have an adverse

effect on the cleaning and disinfecting

results obtained. Pre-treatment agents

need to be completely removed before

placing the items in the

washer-disinfector.

� The process must be adjusted so

that no foam escapes the wash

chamber. Escaping foam jeopardizes

the safe operation of the

washer-disinfector.

� The processing must be checked

regularly by the operator in order to

detect any foaming.

� To avoid damage to the

washer-disinfector and the associated

accessories by the effect of process

chemicals, introduced contamination or

their interaction, the instructions in the

chapter "Chemical Process

Technology" must be followed.

� Even when a chemical additive (e.g.

a cleaning agent) is recommended, the

washer-disinfector manufacturer takes

no responsibility for the effect of such

chemicals on the labware/instruments

involved.

Note that formulation changes, storage

conditions, etc., that are not disclosed

by the manufacturer may adversely

affect the cleaning results obtained.

� When using process chemicals,

always follow the instructions opf the

chemicals manufacturer. To avoid

material damage and the possibility of

violent chemical reactions (e.g.

hydrogen gas reaction), always comply

with the manufacturer's intended

application(s) for a given cleaning

agent.

� For critical applications, where very

high processing requirements have to

be met, it is strongly recommended that

all process-related factors (processing

chemicals, water quality, etc.) be

discussed in advance with Miele.

� In addition, for applications that

demand especially stringent cleaning

and rinsing results, (e.g., chemical

analysis) the operator must ensure that

quality control occurs on a regular

basis, to meet the standards involved.

� Only use mobile units, modular

baskets, and inserts as intended by the

manufacturer.

Hollow items must be positioned for full

exposure to rinse water.

� Empty all liquids from containers

and hollow items before loading them

into the washer-disinfector.

� Ensure that no acid or solvent

residues, especially hydrochloric acid

or chloride solutions, get inside the

wash chamber. Never place corroding

ferrous materials in the

washer-disinfector. Only trace amounts

of any organic solvents should be

present in any soiling.


9

� To avoid corrosive damage, make

sure the stainless steel housing does

not come into contact with

solutions/steam containing hydrochloric

acid.

� After any work on the water supply

system, the water lines to the

washer-disinfector must be bled.

Otherwise some components of the

washer-disinfector may be damaged.

� Please be sure to follow the

installation instructions in this manual

and in the installation manual.

Using Accessories

� Whatever the application, only Miele

accessories should be connected to

this washer-disinfector. Consult Miele

for details on the type of equipment to

use.

� Only Miele mobile units, modular

baskets, and inserts should be used. If

Miele accessories are altered in any

way, or mobile units and inserts from

another manufacturer are used, Miele

cannot assure the cleaning and

disinfection results. Damage or injury

caused in this way are excluded from

the warranty.

� Only use process chemicals that are

approved by their manufacturer for the

application involved. Any negative

effects on labware or instruments and

the washer-disinfector itself are the

liability of the chemical manufacturer.

The type of laboratory glassware can

include anything from beakers, bootles,

cenrifuge tubes, Erlenmeyer flasks,

funnles, pipettes, Petri dishes and

round bottom flasks.

In this operating manual, the general

term labware/instruments is used to

cover a range of equipment and items.

For standardized results, it is preferable

to machine-wash lab/surgical

instruments and equipment.

When disinfection is required to protect

staff and/or patients, the preference is

for thermal disinfection, e. g., with the

DESIN vario TD process.

– An exception are

temperature-sensitive OR shoes which

can be processed using the

CHEM-DESIN program. –

According to the A0 concept described

in EN ISO 15883-1, thermal disinfection

occurs at 80°C (+ 5°C, - 0°C) with

10 min. holding time (A0 600), or at

90°C (+ 5°C, - 0°C) with 5 min. holding

time (A0 3000), depending on the

disinfection result required. The

efficacy standard A0 3000 includes the

inactivation of HBV.

Regional and/or other official directives

like e. g., CSA Z314.8 Decontamination

of reusable Medical Devices are

applicable.

The cleaning parameters should always

be optimally matched to the type of

soiling and labware/instruments

involved.

The processing chemicals used also

should be matched to the particular

cleaning needs / analysis / analytical

methods involved.

Intended Use

11

For re-usable items to be safe for

continued use, the cleaning result must

meet certain minimum standards for

disinfection, sterilization and residue

levels.

Re-usable medical products are best

cleaned with the DESIN vario TD

process or, as appropriate, with the

ORTHOVARIO or OXIVARIO processes.

Also important for acceptable cleaning

results is the use of suitable loading

accessories (mobile units, modules,

inserts). See the section on

"Applications" for examples.

The washer-disinfector is designed to

rinse with tap water or processed water

(e.g., distilled water, pure water,

deionized water, demineralized water)

depending on the quality required for

your application(s). The water quality

selected is especially important for

labware intended for analytical uses.

Under EN ISO 15883, this

washer-disinfector is suitable for

process validation.

User profiles

Daily-routine operators

For daily routine tasks, the operating

personnel must be instructed in the

basic functions and the loading of the

washer-disinfector and should receive

machine-based processing of medical

devices is required.

Daily routine work takes place on

operating levels A and C.

Daily-routine supervisors

Advanced knowledge of the

machine-based processing of medical

devices is required for more complex

tasks such as program interruption or

program cancellation.

These tasks take place on operating

level B.

Service tasks and administration

Additional expertise is required for

changing the processes or adjusting

the washer-disinfector, e. g. the

accessories that are used or the site

The automatic mobile unit recognition

feature assigns a program place to a

mobile unit. For this to work, the mobile

units must be coded with a magnetic

strip (with a bit combination).

In operating level C, each coded

mobile unit is assigned to the

corresponding program place.

When a coded unit is inserted into the

machine and the washer-disinfector

door closes, the automatic mobile unit

recognition selects the assigned

program.

See "Mobile unit coding" in the

washer-disinfector Programming

Manual for information on how to

code a mobile unit and assign

programs.

Make sure that no metallic parts

or pieces are stuck to the magnetic

strip or its underside.

Attached metallic objects can cause

the coding to be misread or be

unreadable.

Mobile units with side coupling are

coded with tracks that have Bit 6 set

to I.

Mobile units without side coupling

must be coded with tracks that do

NOT contain Bit 6.

The magnetic strips in

washer-disinfectors PG 8527 /

PG 8528 must contain black

magnets.

Automatic mobile unit recognition

27

The washer-disinfector can be fitted

with various mobile units, adapted to

the type and shape of the items that

need to be cleaned and disinfected;

they can be equipped with a wide

variety of modules and inserts.

Mobile units, modules and inserts

should be properly selected to

match the application involved.

On the following pages you will find

loading examples and additional

information.

Before EVERY program start,

conduct the following visual

inspection:

– Are the items properly sorted, loaded

and connected in the

washer-disinfector?

– Are the spray arms clean and can

they rotate freely?

– Is the flat filter free of debris (remove

any coarse material and clean the

filter as needed)?

– Is the flat filter horizontally aligned

with the wash chamber and is the

seal flush with the wash chamber?

– Is the adapter properly connected to

the water supply for the spray arms

and nozzles?

– Are the process chemical dispensers

full (detergent, neutralizer, etc.)?

After EVERY program completion,

conduct the following visual

inspection:

– Inspect the labware or instruments

for cleanliness.

– Have any hollow items been

dislodged from their proper position

on the nozzles?

Any items that were dislodged

from the adapters during a program

cycle must be washed again.

– Are the cavities and channels in

hollow items cleaned through?

– Are the nozzles and connections

firmly attached to the mobile

units/inserts?

Protein testing

After washing, items used in medical

applications should be checked at

random for proteins.

Application

28

How to load the

washer-disinfector

Select mobile units, baskets and

inserts appropriate for the

application.

– Always load items in such a way that

all surfaces will be exposed to the

cleaning water. This ensures that the

items will be properly cleaned.

– Do not nest any items inside other

items. Keep each item separate.

– Hollow items must be arranged for

complete inside exposure to the

cleaning water.

– Instruments with long, narrow hollows

must be loaded so that they can be

completely flushed with washwater

and rinsewater.

– Hollow items should be inverted and

placed in suitable mobile units,

modules and inserts so that water

can flow in and out unrestricted.

Protective netting can be used to

avoid damage to sensitive

instruments or glass breakage.

– Lightweight items can be secured

with cover nets (e.g. A 6), and small

parts can be placed in a small item

mesh tray, so that they do not block

the spray arms or become attached

to the magnetic strip on the automat-

ic mobile unit recognition.

– Deep based items should be

arranged at an angle, so that water

can run off easily.

– Tall, narrow hollow items should be

placed in the center of the mobile

unit for best water coverage.

– Mobile units with an adapter must be

properly connected.

– Modules must be properly

connected to the mobile unit.

– The spray arms must not be blocked

by items that are too tall or hang

through the baskets. Gently rotate

the arms by hand to check mobility.

– To avoid corrosion, use only

unblemished instruments made of

stainless steel.

– Heat-sensitive instruments should be

cleaned and disinfected with a

thermochemical process only.

NEVER process disposable

instruments in the

washer-disinfector.

Prepare items before loading

Empty all items before loading into the

machine. Comply with all applicable

infection-control regulations.

Ensure that no acid or solvent

residues, especially hydrochloric

acid or chlorides, get inside the

washer-disinfector.

Instrument sorting

Whenever possible, instruments should

be reprocessed in washer-disinfectors

without pre-soaking.

Application

29

Surgical instruments

The wait-time before processing

surgical instruments should be as short

as possible and should not exceed two

hours.

The instruments should be processed

using the program DES-VAR-TD.

For surgical instruments with a longer

wait time, use the OXIVARIO or

ORTHOVARIO process (see section on

"Optional features").

Surgical instruments, even those for

minimally invasive procedures, should

be thermally disinfected for best

results.

Whenever possible, demineralized

water should be used for rinsing

(conductivity ~ 15 �S/cm) for a spotless

result and to avoid corrosion. The use

of tap water with more than 100 mg

chloride/L entails the risk of corrosion.

When processing instruments for

minimally invasive procedures, e.g.,

minimal invasive surgery an intensive

internal cleaning result is imperative.

Only the programs DES-VAR-TD and

OXIVARIO are suitable for thorough

cleaning. Always observe the specific

loading instructions, and all applicable

procedures, including for the use of

appropriate detergents for these

sensitive instruments.

For rinsing, use demineralized water

with a conductivity of ~15 �S/cm.

Very narrow-lumen instruments must

be pre-cleaned manually where

necessary. Follow the instrument

manufacturer's instructions!

Most rigid sterilization containers can

be processed thermally with the

CONTAINER program. For anodized

alumium containers, demineralized

water must be used for cleaning and

rinsing.

They should not be cleaned at 93 °C

mit and 10 min holding time with an

alkaline detergent.

When processing surgical container

with a disinfection standard A0=600 the

program CONTAINER-600 must later

be programmed by Miele.

The mobile units for surgical

instruments and sterilization

containers come with their own

operating instructions.

Application

30

Ophthalmology

Using the E 929/1 mobile unit,

ophthalmological surgical instrument

sets can be cleaned and disinfected

automatically.

For rinsing, use demineralized water

with a conductivity of ~15 �S/cm

(microsiemens per centimetre).

In addition, the rinse water must have a

low endotoxin and pyrogen content!

The upper level is equipped with

separate connections for hollow

instruments, e.g. rinse and suction

grips and cannulae.

Silicone holders and stoppers fitted on

the mesh tray fix and secure the

instruments to the inlet hose of the

mobile unit.

The lower level of the mobile unit is

fitted with E 441/1 inserts or E 142

mesh trays to prepare instruments

without a hollow body.

In washer-disinfectors used to

process small-calibre

ophthalmological instruments,

plastic mesh must not be used.

The mobile units for

ophthalmological surgical instrument

sets come with their own instructions

for use.

Mobile unit E 929 (for

ophthalmological surgical

instruments) must only be used in

washer-disinfectors that do NOT

have a dispensing system with a

flow rate of 465 mL/min installed.

Ophtalmological instruments

must not be treated in

washers-disinfectors with steam

condenser with heat recovery

(DK+WRG option)!

Application

31

Anesthesia instruments (AN)

Anaesthetic instruments should be

thermally disinfected using the program

DES-VAR-TD-AN.

If no sterilization will occur after

washing, germ growth will need to

be inhibited during storage.

Because this requires thorough

drying, a sufficient amount of drying

time must be selected.

The units for anaesthesia

instruments come with their own

instructions for use.

Application

32

Baby bottles

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.

– Only use baby bottles with

dishwasher-safe volume markings.

– Bottles that are stored for longer than

4 hours prior to processing must be

filled with water to prevent food

residues from drying on the surface.

If no sterilization will occur after

washing, germ growth will need to

be inhibited during storage.

Because this requires thorough

drying, a sufficient amount of drying

time must be selected.

The inserts for baby bottles and

nipples come with their own

instructions for use.

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.

Application

33

OR shoes

OR shoes made of

temperature-sensitive material and/or

insoles must be thermochemically

cleaned and disinfected at 60°C

(program CHEM-DISIN).

A thermal disinfection program

(SHOE-TD-75/2) can be used as long

as the manufacturer has confirmed the

thermal stability of the product(s).

For information on the efficacy of

thermochemical disinfection, contact

the disinfectant manufacturer directly.

OR shoes should only be cleaned

and disinfected in a

washer-disinfector that has been

installed for that application.

If OR shoes are processed with

other applications in a

washer-disinfector, the operator

must assess the risks associated

with this.

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

(European), size 10 (US) can be

placed in the lower level of mobile

unit E 975/1,

– Insert E 931 for up to shoe size 48

(European), size 15 (US).

When OR shoes are cleaned, large

quantities of lint can accumulate. For

this reason, be sure to check the

wash cabinet filters frequently and

clean as needed (see the “Cleaning

the wash cabinet filters” section in

“Maintenance of the

washer-disinfector”).

Application

34

Laboratory equipment

Wide-necked labware, e. g., beakers,

wide-necked Erlenmeyer flasks and

Petri dishes, or cylindrical items, e. g.,

test tubes, can be cleaned inside and

out by the rotating spray arms. For

proper cleaning, load these items in

whole, half or quarter inserts and place

them in an empty lower basket or upper

basket with spray arm.

For narrow-necked equipment, e. g.,

narrow-necked Erlenmeyer flasks,

round-bottomed flasks, measuring

cylinders and pipettes, you will need to

use injector baskets or injector

modules.

This section only covers basic

information on how to prepare and load

labware.

How to load the machine

– Petri dishes and similar items should

be loaded in a suitable insert, with

the soiled side facing center.

– Load pipettes with the tip facing

down.

– Quarter baskets should be arranged

as far from the centre as possible.

– Do not let glass items protrude near

the door opening.

Prepare items before loading

� Empty all glassware before loading

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 program

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.

– Follow the instructions and


chemical manufacturers.

than 70 °C when using hydrogen

peroxide.

– Please contact Miele for advise.

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 program block in which the

chemical agent is dispensed,

– in the following program block if it

has been spilt,

– in the following program with rinsing

agent if it has been spilt.

– Process parameters in the wash

program, such as dispensing

temperature, dosage concentration

etc. must be set to ensure the whole

process is foam free or very low

foaming.

– Please observe chemical agent

manufacturer's instructions.


38

The following substances can lead to a

heavy build-up of foam during washing

and rinsing:

– Some disinfecting agents and

cleaning 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 program 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.

– Use the OIL program where available

or an optional "Oil" program defined

by Miele Service.

– This special program 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 program 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 chemical agent

manufacturer's instructions.


41

Use only detergents and

neutralizers specially designed for

use in washers-disinfectors, and

observe the manufacturer's

recommendations for use! ALWAYS

refer to the information regarding

toxicologically harmless residual

amounts.

The washer-disinfector can be fitted

with a maximum of 5 internal

dispensing systems. They are

colour-coded, to match the dispensing

pumps to the corresponding siphon

tubes.

Dispensing system Colour coding

1 blue

2 white

3 red

4 green

5 yellow

Depending on the application(s)

chosen for this washer-disinfector, the

appropriate amounts of detergent and

neutralizer are dispensed through these

systems.

The washer-disinfector comes with two

internal dispensing systems as stan-

dard equipment:

– Dispensing system DOS 1 for use

with alkaline products, e. g., liquid

detergents. The dosing rate is

200 mL/min.

– Dispensing system DOS 3 for use

with acidic products, e. g.,

neutralizers. The dosing rate is

105 mL/min.

Up to three additional dispensing

systems can be installed optionally:

Dosing rate Product(s)

465 mL/min alkaline

200 mL/min alkaline

105 mL/min acidic

Instead of the internal dispensing

system, up to five external dispensing

systems can be connected to the

washer-disinfector.

For special applications, the external

dispensing systems can also be

activated, in addition to the internal

systems.

If a dispensing system is to

dispense different process

chemicals, the change of chemicals

must be carried out by the Miele

Service Department.

For all special information about

the OXIVARIO and ORTHOVARIO

processes and how to connect the

container with H2O2 solution, see the

section on "Optional Equipment -

Optional equipment - OXIVARIO

For the OXIVARIO process, dispensing

systems 2 and 5 are needed, to

dispense a hydrogen peroxide solution

(H2O2 solution).

The dispensing systems for H2O2

solution are colour-coded black.

The dosing rate for system 2 is 105

mL/min. Dispensing system 5 runs the

H2O2 solution through the

washer-disinfector.

The OXIVARIO option makes

dispensing system DOS 5

unavailable for dispensing any other

processing chemical.

Optional equipment - ORTHOVARIO

For the ORTHOVARIO process, the

washer-disinfector must be fitted with

an additional dispensing pump in

dispensing system DOS 4 (add-on

equipment):

– Dispensing system DOS 4 (green) for

dispensing a special tenside

detergent. The dosing rate is

105 mL/min.

The ORTHOVARIO option makes the

DOS 4 dispensing system

unavailable for dispensing chemical

disinfectants.

if applicable:

– the drying unit.

During maintenance, the following

function checks are run:

– a program test run,

– electrothermal measurement,

– seal testing,

– all safety-related measurement

systems (fault report)

– the safety features.

Process validation

It is the responsibility of the operator to

routinely check that the required

cleaning and disinfection processes

are functioning properly.

In some countries, this is also required

by national legislation, regulations, or

recommendations.

Operators are also required to conduct

such checks under international stan-

dard EN ISO 15883, ; CAN/CSA

Z15883.

Routine checks

Before each day's use, the operator

must conduct a series of routine

checks. A routine checklist is supplied

Maintenance of the washer-disinfector

62

Cleaning the filters in the wash

cabinet

The flat filter in the bottom of the wash

cabinet and the filters in front of the

circulation pumps prevent the

introduction of contaminant particles

into the circulation system.

The washer must not be

operated without the filters in place.

Risk of injury due to glass

splinters, needles, etc. which are

retained by the flat filter.

Cleaning the flat filter

Retained contaminant particles may

clog the flat filter. For this reason, the

filter requires cleaning at least once

every day.

If heavy contamination is visible after a

program cycle, the flat filter requires

cleaning before the program is started

again.

If there is any visible residue on the

flat filter after manual cleaning, it can

be removed by cleaning in the

washer-disinfector.

The exact process depends on the

mobile unit. Please contact Miele

Technical Service if you have any

questions.

filter.

Do not pull at the ventilation pipes

as they could bend and thus lose

some of their functionality.

� Use running water (and a brush, if

necessary) to rinse off deposits and

contaminants.

� Blow compressed air through the flat

filter from the back against the

direction of flow.

� Replace the flat filter.

Insert the flat filter horizontally and

ensure that the gasket is flush with

the washing cabinet.

� Manually turn the lower machine

spray arm to check its free rotation.


63

Cleaning the filter in front of the

circulation pumps.

Two filters for the protection of the

circulation pumps are installed below

brackets and clean under running

water.

� Replace the filters.

� Replace the flat filter.

Check that all filters have been

properly returned.

� Manually turn the lower machine

spray arm to check its free rotation.


64

Cleaning the spray arms

The spray arms can become clogged.

Check them daily and clean if needed.

� Use a sharp pointed object to push

any particles into the spray arm jets,

then rinse thoroughly under running

water.

To do so, remove the spray arms as

follows:

� Remove the mobile unit.

Washer-disinfector spray arms

� Loosen the nut with a wrench and

pull the spray arm either upward or

downward.

Spray arms on mobile unit / inserts

� Use a wrench to loosen the nut on

the spray arm guide, then pull the

spray arm downward.

If you notice wear and tear on the

Optional equipment

73

Intended Use

The washer-disinfector can be

equipped (or retro-fitted) for the

OXIVARIO process, with two additional

dispensing pumps and an intermediate

reservoir for hydrogen peroxide solution

(H2O2solution). In this case, the DOS 2

dispensing system will dispense the

H2O2solution.

For the ORTHOVARIO process, the

DOS 4 dispensing system must be

equipped (fitted) with a special

dispensing pump for a special tenside

detergent.

The OXIVARIO PLUS, OXIVARIO and

ORTHOVARIO programs are available

for the special processes.

The OXIVARIO process uses active

oxygen release under alkaline

conditions. The detergent used in this

process must be tenside-free, with a

pH value between 11 and 11.5.

The ORTHOVARIO process uses a

material-tolerant tenside detergent in

the first cleaning phase, and active

oxygen release in the second phase,

produced at a pH between 10.0 and

11.0 at a slightly higher temperature of

65°C.

Applications

The OXIVARIO process uses alkaline

cleaning, and is designed to meet the

special demands involved in the

preparation of surgical instruments.

This process is especially suited to the

preparation of OP instruments, i. e.,

from HF (high frequency) surgery,

orthopaedic surgery,

instruments that dry out during long

delays until preparation, and for

instruments affected by antiseptics.

The OXIVARIO PLUS process is

designed to prevent iatrogenic prion

transmission (vCJK).

The cleaning processes are gentle

enough for minimally invasive

instruments, including ophthalmic, as

long as the manufacturer has approved

alkaline cleaning methods for them.

However, this process is not suitable for

anodized aluminium. The materials in

titanium alloys, e.g., implants, may vary

in terms of material tolerance.

Colour-coding can change, resulting in

errors. Consult the manufacturer for

verification.

The ORTHOVARIO program is

designed for the material-tolerant

preparation of alkaline-sensitive

instruments made of aluminum, in

particular for instruments used in

orthopaedics, e.g., for motor systems.

The oxidative effects of this process

make it unsuitable for titanium alloys,

in particular for colour-coded

implants.

The processes clean so

thoroughly that, to prevent

damages, instruments with metal

surfaces sliding across each other

must be carefully attended to with

suitable material immediately

following preparation.

Safety instructions and

warnings

These safety instructions and

warnings are in addition to those

found at the beginning of the

Installation and Operating

Instructions!

� The H2O2solution must only be used

in special containers from "Ecolab" or

"Dr. Weigert", with the matching

adapters.

� Always read and comply with the

material safety data sheets from the

manufacturers of the process

chemicals.

� Exercise care when handling

H2O2solution - it is a corrosive

substance!

Always comply with all applicable

safety regulations!

Use protective eyewear and gloves.

� Follow the manufacturer's

instructions for disposal of empty

containers.

� The H2O2solution must never be

mixed with any other processing

chemicals. A violent chemical reaction,

such as a flash fire, may occur.

� Only special tenside detergents

from "Ecolab" or "Dr. Weigert" should be

used.

Connecting the H2O

2

container(s)

The hose line for the H2O2 container is

identified by a black label. It is supplied

Functional description

Washers-disinfectors with a steam


(DK+WRG) are identified with this

symbol.

The variant Steam condenser with heat

recovery (DK+WRG) may be used only

with a built-in boiler.

In this variant, the steam condenser is

connected to the AD water and not to

the cold water supply. The AD water

used as cooling medium flows through

the steam condenser, where it is

preheated, into the boiler of the

washer-disinfector.

Thus, heating the boiler water requires

less energy. Compared to a connection

of the steam condenser to the fresh

water supply, this variant also reduces

the overall water consumption.

Due to the modified water conduits in

the washer-disinfector, the water inlet

times increase in purge blocks using

warm AD water.

Intended application

Washers-disinfectors with Steam


(DK+WRG) may be only used in

medical applications.

For optimum utilization of the heat

recovery system, operate the

washer-disinfector without extended

standstill times.

After extended standstill times

such as weekends, start the FILL

BOILER utility before starting

operation.

For hygienic reasons, the AD water

from the steam condenser and the

boiler is replaced by fresh, cold AD

water.

SAFETY INSTRUCTIONS AND

WARNINGS

These safety instructions and

warnings apply in addition to those

found at the beginning of the

Operating Instructions!

� Ophthalmological instruments must

not be treated in washers-disinfectors

with the Steam condenser with heat

recovery (DK+WRG) option!

� When using the heat recovery

function, do not lower the boiler

temperature of 90 °C. For sensitive

wash ware such as optical instruments

for example, select a process without

thermal shocks. For instance, use warm

water in the last purge block before the

thermal disinfection.

� In the case of very delicate wash

ware, please verify whether it is suited

for the treatment in a process with

potential changes in temperature.

Please follow the instructions provided

by the manufacturers of the wash ware

and the instruments.
