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. 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 or operation of the machine.

This machine is intended for indoor

use only.

This machine is not designed for

use in mobile installations unless a risk assessment of the installation has been carried out by a suitably qualified engineer.

notes to avoid injury and damage.

This machine should be

commissioned and then maintained by a Miele authorised and trained service technician only. A Miele service contract is recommended to ensure compliance with GLP Guidelines and the Medical Devices Directive. Unauthorised repairs could be dangerous, for which the manufacturer cannot be held liable.

Do not install the machine 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 tested regularly, and where there is any doubt the on-site electrical system should be inspected by a qualified electrician. The manufacturer cannot be held liable for damage or injury caused by the lack of or inadequacy of an effective earthing system (e.g. electric shock).

A damaged or leaking machine

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

Personnel operating the appliance

should be trained regularly. Untrained personnel must not be allowed access to the machine or its controls.

Warning and safety instructions

Take care when handling chemical

agents such as cleaning agent, neutralising agent, rinsing agent etc. These may contain irritant or corrosive ingredients. 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 machine is designed for

operation with water and recommended additive 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.

When using this machine in the

higher temperature ranges, be especially careful not to scald or burn yourself or come into contact with irritant substances when opening the door. Where disinfecting agents are used there is a danger of inhaling toxic fumes.

Where there is a risk of toxic or

chemical substances occuring in the suds solution (e.g. aldehyde in the disinfecting agent), it is essential to regularly check door seals and make sure that the steam condensor is functioning correctly. Opening the machine door during a programme interruption carries particular risks in such circumstances.

Should personnel accidentally come

into contact with toxic vapours or chemical agents, follow the emergency instructions given in the manufacturer's safety data sheets.

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.

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 water 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.

Warning and safety instructions

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 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 must be routinely confirmed by the user. The process should be validated on a regular basis, and checked against documented control results. Chemical disinfection procedures should also be validated using chemical or bio indicators.

For thermal disinfection, use

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

Disinfection programmes which use

a chemical disinfecting agent at moderate temperatures such as 65 °C or lower are not recognised by §18 IfSG for disinfection. They should only be used for items which cannot withstand the higher temperatures used by thermal disinfection. The range of effective disinfection is based on claims made by the producer of the disinfecting agent. Their instructions on handling, use and effectiveness must be observed. The use of chemical disinfection procedures is the responsibility of the operator.

Theatre (OP) shoes should only be

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

Only use chemical agents

formulated for special processes and approved by Miele for use with this machine. Use of unsuitable agents could adversely affect the components of the machine. In the event of any damage or material deterioration please contact your Miele application specialist.

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.

Warning and safety instructions

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 cleaning agents and

specialised products it is essential that the manufacturer's instructions are followed. Chemicals must only be used for the purpose they are designed for and in the situation specified, to the exclusion of other chemicals, to avoid such dangers as chemical reactions and material damage.

In critical applications where very

stringent requirements have to be met, it is strongly recommended that all the relevant factors for the process, such as chemical agents, water quality etc. are discussed with the Miele Application Technology specialists.

If the cleaning result is subject to

particularly stringent requirements, a regular quality control test should be carried out by the user to ensure that required standards of cleanliness are being achieved.

Mobile units, modules and inserts

should only be used for the purpose they are designed for. Hollow instruments must be thoroughly cleaned, internally and externally.

Empty any containers or utensils

before arranging them in the machine.

Do not allow any remains of acids or

solvents, and in particular hydrochloric acid or chloride solutions, to get into the wash cabinet. Similarly avoid any materials with a corrosive effect. The presence in compounds of any solvents should be minimal (especially those in hazard class A1).

Ensure that solutions or steam

containing hydrochloric acid do not come into contact with the steel outer casing of the machine, to avoid any corrosion damage.

Please follow the advice on

installation in these instructions and the separate Installation Instructions.

Using accessories

Only use genuine Miele original

accessories with this machine. 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.

Warning and safety instructions

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.

Symbols on the appliance

Warning: Observe the operating instructions.

Warning: Danger of electric shock.

Disposing of your old machine

Please note that the machine may

have contamination from blood or other bodily fluids in it and must be decontaminated before disposal. For environmental and safety reasons ensure the machine is completely drained of any residual water, chemical residues and cleaning agent. Observe safety regulations and wear safety goggles and gloves. Make the door lock inoperable, so that children cannot accidentally shut themselves in. Then make appropriate arrangements for its safe disposal. For tank system machines ensure that any water is emptied out of the tank.

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

Intended Use

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

Examples of application areas:

surgical instruments,

–

minimally invasive instruments,

–

anaesthetic and intensive care

–

instruments,

– baby bottles and teats,

– stainless steel and aluminium

containers (including anodised aluminium),

– operating theatre shoes.

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

concept) vary depending on the disinfection standard required. They are 80 °C (+ 5 °C, - 0 °C) with a 10 min holding time (A

600) or 90 °C (+ 5 °C,

- 0 °C) with a 5 min holding time (A

3000). An A0value of 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 agents used for processing the products should be selected to suit the level of cleaning required as well as the method of analysis used.

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 processed 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 the load. Examples are given in the section "Areas of application".

The washer-disinfector is programmed to carry out the final rinse with mains water or with processed water of a quality to suit the application (e.g. aqua destillata, purified water, de-ionised water, demineralised water).

This machine complies with EN ISO 15883 for validation purposes.

Water softener softener (Optional)

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° d – 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.

The water softener is set ex-works for a hardness level of 3.4 mmol/l or 19°d.

If your water hardness differs from this (even if it is below 0.7 mmol/l or 4°d) you will need to programme the level into your machine.

Where the water hardness fluctuates e.g. between 1.4 - 3.1 mmol/l (8 - 17 °d German scale) always programme the washer-disinfector to the higher value (3.1 mmol/l in this example).

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

Enter your water hardness level here:

°d or mmol/l

Setting the water softener

When the machine is first commissioned the Miele service technician has to set the machine for your local water hardness level (see Programme manual, Operation/Reactivation).

Reactivation display

After a certain number of cycles the message REACTIVATION will appear in the display to warn you that the water softener is depleted and cannot supply any more softened water. As soon as the programme has finished reactivation salt will need to be replenished.

If this cannot be done immediately, and further cleaning cycles have been carried out, the reactivation process will need to be carried out twice in succession.

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

10.8 mmol/l).

Water softener softener (Optional)

Reactivating the water softener

Please only use special coarse grained reactivation salt with granules of approx. 1-4 mm. Do not use other types of salt, e.g. table salt, agricultural or gritting salt. These could contain components which are insoluble in water which could result in damage to the water softener. If in doubt consult the Miele Professional Department.

The salt container holds approx. 2 kg of salt.

If only fine grained reactivation salt is available please consult the MIELE Professional Sales office for advice. Salt with granules ü 4 mm must not be used in this machine.

Inadvertently filling the salt

reservoir with cleaning agent can cause serious damage to the water softener and damage the filter insert, and cause pressure to build-up in the salt container. To avoid the risk of injury please exercise caution when removing the salt container as there may be irritant alkaline solutions present. Before filling the salt container make sure that you have picked up the right packet of reactivation salt.

Water softener softener (Optional)

Filling the salt container

^ Unscrew the filter insert from the salt

container and remove.

^ Fill the salt container with reactivation

salt and screw the filter insert back in place.

Position the salt container as follows

^ Remove any mobile units from the

cabinet.

^ Unscrew the plastic cap situated in

the top right-hand side of the cabinet.

There will be a small amount of residual water in the cap. Take care as it may be hot from the previous programme.

Screw the salt container firmly onto the socket.

Water softener softener (Optional)

Run the reactivation programme

Close the door.

Open the stopcocks.

Select the REACTIVATION

programme.

The programme will run automatically.

Then:

Switch off the machine.

Carefully unscrew the salt container,

making sure any water pressure still remaining can depressurise. Do not use force! If the container will not come off manually please contact the Miele Service Department.

^ Replace the plastic cap.

^ Push the mobile unit back into the

cabinet.

The water pressure (flow pressure at the take off point) must be at least 100 kPa (1 bar). If it is below100 kPa (1 bar) or if it fluctuates a lot, the water softener will not work properly. After reactivation, salt remains may still be found in the salt container. To use up salt remains and to rinse out the water softener, the REACTIVATION programme must be carried out again.

^ Turn off the stopcocks.

^ Empty the salt container. Do not

empty it into the wash cabinet.

Rinse the salt container and filter insert with clean water.

Automatic mobile unit recognition (Optional)

In operating level C the automatic mobile unit recognition system (AWK) allocates programme places from 1 15 to mobile units with the correct coding.

The unit coding (on the mobile unit) and the programme place with the corresponding programme (in the electronic control unit) have to match each other.

To do this:

Each mobile unit must be coded

before being used for the first time (see "Coding the mobile unit"), and

^ The programme for which the mobile

unit is coded must be allocated to the correct programme place.

See "System function - Selector switch organisation" in the Programming manual for information on how to change programme positions.

Before starting a programme it is

absolutely essential that you check that the programme shown in the display is the correct one for the mobile unit being used. Otherwise inadequate cleaning or disinfection could be the result. Please make sure, that the places assigned for the programmes using Automatic mobile unit recognition are not changed around arbitrarily.

Automatic mobile unit recognition (Optional)

Mobile unit coding

The automatic mobile unit recognition feature assigns a programme place to a mobile unit. The mobile units must be coded with a magnetic strip (via a Bit combination). In operating level C, the only programme available for a coded mobile unit is the one assigned to the corresponding programme place.

After a coded mobile unit has been put into the machine and the door closed, the automatic mobile unit recognition system will select the allocated programme.

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.

Coding is effected through 5 Bits:

Bits 1 to 4 define the mobile unit

–

code,

– Bit 5 serves as a control (Parity Bit).

Bit 6 controls the volume of inflowing water and the circulation pump for mobile units with side coupling (WAK). Its settings cannot be altered. Mobile units without side coupling are coded with tracks which do not contain Bit 6.

Press 6 to start the programme.

Automatic mobile unit recognition (Optional)

Mobile unit coding strip

15 different codes can be set. They are assigned to programme places 1 to 15.

Under "System function, Selector switch organisation" the matching programmes have to be put into the first 15 programme places.

Setting mobile unit coding

To set or alter the coding of a mobile unit with automatic recognition (AWK), proceed as follows:

^ Unscrew the track with AWK (using

an allen key) and remove from the retainer.

The coded total must be an even number. The settings on Bit 6 (WAK) are not included in this calculation.

If the coded total gives an odd number, the message CHECK MOBILE UNIT RECOGNITION appears. If the mobile unit code equals 0, the message NO MOBILE UNIT RECOGNITION appears. In neither case can the programme be started, The mobile unit recognition function must be re-set.

Remove the magnetic strip from the track.

mobile unit and screw firmly in place.

Bit 6 (WAK) is not a component part of the modifiable magnetic strip. Make sure that you code mobile units with side connection with a track where Bit 6 is set to I. Mobile units without side coupling must be coded with a track without Bit 6. The magnetic strips on G 7823 / G 7824 / G 7825 / G 7826 must have grey magnets. The magnetic strips on G 7827 / G 7828 must have black magnets.

The magnetic strip must be placed in the track such that the Bit coding set out in the chart is visible through the round windows in the track.

Areas of application

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?

–

Are the filters clean? Remove any coarse soiling and clean them properly if necessary.

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.

–

Is the adapter connecting the water supply to the spray arms/jets correctly connected?

–

Are all chemical containers sufficiently filled?

Areas of application

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 disinfected.

Disposable instruments must not

be put into the machine for processing.

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.

Areas of application

Surgical instruments (OP)

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

The OXIVARIO or ORTHOVARIO processes 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 preferably take place thermally.

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

When cleaning narrow lumen

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

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

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

OP-containers can be disinfected thermally in the CONTAINER programme, or chemically. If anodised aluminium containers are used the final rinse must be carried out with fully demineralised water. These containers must not be processed with an alkaline cleaning agent in a 93 °C programme with 10 minutes holding time (according to § 18 IfSG).

Mobile units for surgical instruments and containers are supplied with their own operating instructions.

Areas of application

Ophthalmology

Opthalmic instruments should be cleaned and disinfected in a special mobile injector unit.

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 processing solid instruments.

Plastic fibre cover nets must not be used in washer-disinfectors which are used to process hollow ophthalmic instruments with narrow lumen.

The mobile injector unit for ophthalmic instruments is supplied with its own operating instructions.

Anaesthetic instruments (AN)

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

If this is not possible, they can be processed using a chemical disinfection programme. The water level in the machine should be increased when using a chemical disinfection programme. To establish the effectiveness of disinfection, consult the manufacturer of the disinfecting agent being used.

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.

Areas of application

Mobile units for anaesthetic instruments are supplied with their own operating instructions.

Areas of application

Baby bottles (BC)

Baby bottles can be processed in E 135 containers, wide-necked teats in an E 364 insert and screw connection teats in an E 458 insert.

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.

The angled positioning of the containers ensures that the jets of water reach right into the bottles.

Areas of application

The two blocked corners in the inserts should be located over the positions marked with an X on the drawing. The jets of water cannot get into the bottles properly in these positions to clean them.

Areas of application

Operating theatre shoes (OS)

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

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

Theatre shoes should be cleaned and disinfected in a machine

installed specifically for this purpose only.

Moble unit E 550 with a suitable insert e. g. E 730, can be used for this purpose.

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

Transfer trolley for loading and unloading the machine

When a disinfection process is

being carried out according to nationally laid down hygiene standards (e.g. § 18 IfSG), the contaminated surfaces of the trolley must be disinfected, after the machine has been loaded, using a spray disinfectant in accordance with national health and safety regulations and § 18 IfSG. Disinfecting agents listed by DGHM (German institute for microbiology and hygiene) are also suitable.

The height of the transfer trolley can be adjusted using the feet. The height should be set so that the open machine door is held underneath the side catches on the transfer trolley.

If the machine is not fitted on a plinth the position of the foot pedal on the transfer trolley may need to be changed.

Areas of application

^ Unscrew foot pedal a.

^ Loosen counter nut b on adjusting

screw c.

^ Screw adjusting screw c further into

the foot pedal, so that the stopping point is reached earlier.

^ Re-secure the adjusting screw.

^ Screw the foot pedal back on.

Areas of application

Hang the mobile unit into the locating

slots on the transfer trolley using both hooks.

^ To lift the mobile unit step down on

the transfer trolley foot pedal.

^ Push the transfer trolley under the

open door on the washer-disinfector as far as it will go. The mobile unit will then sit over the door.

^ Secure the brakes on the wheels.

To lower the mobile unit step right down on the foot pedal.

At the end of the programme push the transfer trolley up to the washer-disinfector making sure that the door of the machine is held underneath the side catches on the transfer trolley.

Then pull the mobile unit out as far as it will go onto the open door, so that it can be lifted up and taken away by the transfer trolley.

Chemical processes and technology

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.

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..

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 damage

Description of the machine

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 H

. The DOS 2 dispenser is used for

2O2

the H

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 the ORTHOVARIO programmes are available for these requirements. The machine is supplied with these programmes allocated to programme places 51 to 53.

2O2

solution.

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.

Special processes - OXIVARIO and ORTHOVARIO

Areas of application

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

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

The ORTHOVARIO procedure is suitable for processing 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 colded 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.

2O2

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

Empty containers must be disposed

of in accordance with the manufacturer's instructions.

H2O2solution 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.

Connecting the H2O2solution container

The connection hose for the H2O 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 H

solution container.

^ Then start the

programme.

Unlike with other chemical agents the H

solution container must be fully

2O2

emptied before it is exchanged for a new one.

Do not replace the H container with a new one until the
