Description of the machine

This Miele washer-disinfector is capable of cleaning a wide range of medical and laboratory products, and disinfecting them either thermally in temperatures up to 95 °C or chemothermally in temperatures up to 65 °C with the addition of a suitable chemical agent in accordance with general standards of hygiene and those required for the containing of epidemics. Medical products include e. g. surgical and minimally invasive instruments, instruments and utensils used in anaesthetics and intensive care, etc. Laboratory products include e.g. wide and narrow necked flasks, conical flasks, measuring cylinders, pipettes, beakers, Petri dishes etc.

Follow medical and laboratory product manufacturer’s instructions on how to process their items by machine. The DESIN vario TD programme provides optimum protection for rigid fibre optics, patient systems and surgical motor systems which have been declared by their manufacturers as being suitable for machine processing. Optional drying with sterile filtered hot air is also available.

Areas of application:

surgical instruments,

–

minimally invasive instruments which

–

can be processed shortly after use, anaesthetic and intensive care

–

instruments, baby bottles and teats,

–

stainless steel and aluminium

–

containers (including anodised aluminium),

operating theatre shoes,

– – laboratory products used in research

and production as well as in all areas of analysis and specimen taking, including micro-biology and biotechnology.

Instruments should preferably be cleaned and then thermally disinfected using the DESIN vario TD programme. The parameters for thermal disinfection in accordance with prEN ISO 15883-1 are 80 °C (+ 5 °C, - 0 °C) with a 10 min. holding time or 90 °C (+ 5 °C, - 0 °C) with a 5 min. holding time for the inactivation of HBV.

Description of the machine

In the U.K. reference should be made to your local infection control officer for guidelines of disinfection temperatures and holding times at temperature in accordance with HTM 2030.

In Germany, the parameters for disinfection of a temperature of 93 °C, with a holding time of 10 minutes, correspond to effective areas A and B. These have been adopted into the official list for disinfection of instruments in washer-disinfectors and decontamination units, according to section 3.2 § 18 IfSG by the Robert Koch Institute (RKI) in Berlin (Institute for Infectious diseases and non-communicable illnesses). The effective areas are defined as follows: A = Suitable for the destruction of vegetative bacteria, including myco-bacteria, fungi and fungal spores. B = Suitable for inactivating viruses (including HBV and HIV).

The cleaning programme must be chosen according to the type of soiling and product requiring processing in order to ensure that disinfection is carried out correctly, no residues are left behind and that subsequent sterilisation can take place. Medical devices are best reprocessed using the DESIN vario TD programme, or the OXIVARIO programme where applicable.

This washer-disinfector is programmed to carry out the final rinse with mains water or AD water (aqua destillata = purified or de-ionised water (VE), H

pure, demineralised water, aqua purificata or distilled water where the application requires this standard). The water quality is of particular importance for applications requiring analytically clean laboratory glassware. The type of chemical agents used will depend on the analysis or analytical methods being used.

Optional extras

– Drying unit (TA) – Steam condenser (DK) – Report printer (PRT) – OXIVARIO kit

Water softener

If the mains water hardness level is more than 70 mg/l (4°d), a water softening system should be provided on-site, such as the Miele G 7897 "Aqua-Soft system" which is effective up to approx 720 mg/l (40°d).

Warning and safety instructions

This machine complies with all relevant legal safety requirements. Incorrect use can lead to personal injury and damage to property. Read these operating instructions carefully before starting to use this machine. This way you will avoid the risk of accidents and damage to the machine. Keep these instructions in a safe place for reference, and pass them on to any future user.

Correct use

This washer-disinfector is designed

for commercial use and for specialised applications only, as described in these operating instructions. 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 products and laboratory ware 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. The manufacturer cannot be held liable for damage caused by improper or incorrect use of the machine.

This equipment may only be used

in mobile installations such as ships, aircraft etc. if a risk assessment of the installation has been carried out by a suitably qualified engineer.

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

The machine should be

commissioned and then maintained only by a Miele authorised and trained service technician. To ensure compliance with the Medical Devices Directive a Miele service contract is recommended. Repairs and other work by unqualified persons could be dangerous.

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 tested regularly, and where there is any doubt the 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).

Warning and safety instructions

A damaged machine is a safety

hazard. Switch off at the mains immediately and call the Miele Service Department or an authorised and trained Miele Service Dealer.

Personnel operating the machine

should be trained regularly. Untrained personnel must not be allowed access to the machine or its controls. This machine is not a toy! To avoid the risk of injury never allow children to play on or near the machine, or to operate it.

Take care when handling

chemicals such as cleaning agent, neutralising agent, rinsing agent etc. These may contain irritant or corrosive ingredients. Do not use organic solvents as these could cause an explosion. Follow all relevant safety procedures carefully. Wear protective gloves and goggles. With all chemical agents, the manufacturer’s safety instructions must be observed.

The water in the machine 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. Baskets, inserts and utensils 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 everything in the cabinet from the load itself to the mobile units, modules and inserts to cool down.

Do not touch the heating elements

(under the wide area filter) during or directly after the end of a programme. You could burn yourself. The elements remain hot for some time after the end of the programme.

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 left 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 water hose or a high pressure hose.

Warning and safety instructions

The machine must be

disconnected from the mains electricity supply before any maintenance or repair work is carried out. Do not reconnect it until the maintenance or repair work has been successfully completed.

The following points should be observed to assist in maintaining quality standards for processing medical instruments 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.

For decontamination in

accordance with official regulations, the programme must not be interrupted by pressing the I-0 button to switch off after START has been pressed. Interrupting any other programmes should also be avoided as this will reduce cleaning, disinfection and the final rinse results. If it is opened the programme should be completely repeated.

The standard of cleaning and

disinfection in the disinfection programmes must be routinely confirmed by the user. The process should be regularly monitored using thermo-electrical, chemical or bio-indicators, and this should be fully documented.

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 chemothermal disinfection procedures is the responsibility of the operator.

If there are toxic or chemical

substances in the suds solution (e.g. aldehyde in the disinfecting agent) you must be particularly vigilant of the risks these carry should you need to interrupt a programme and open the door. The door seals and correct functioning of the steam condenser should be regularly monitored.

Warning and safety instructions

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. Any resultant damage would invalidate the machine guarantee.

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 process.

Where a chemical additive 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. Only use the product for the application described by the manufacturer, to avoid any material damage or the occurrence of strong chemical reactions.

The machine is designed for

operation with water and additive chemical agents only. Organic solvents must not be used in this machine, as there is the danger under certain circumstances of fire or explosion. Although this is not the case with all organic solvents, other problems could arise with their use, for example damage to rubber and synthetic materials.

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 cleaning and rinsing results are

subject to particularly stringent requirements (e.g. chemical analysis, specialised industrial processes etc.), a regular quality control test must be carried out by the user 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.

Warning and safety instructions

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

accessories with this machine. Consult Miele on the type and application of such equipment.

Only use Miele mobile units,

baskets and inserts in this machine. Using accessories made by other manufacturers, or making modifications to Miele accessories can result in unsatisfactory cleaning and disinfecting results, for which Miele cannot be held liable. Any resultant damage would also invalidate the machine guarantee.

Disposal of your old machine

Before throwing an old machine

away it must first be made unusable. Disconnect from the mains and cut off the cable as close to the machine as possible. 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, and block or disable the door in such a way that children cannot accidentally shut themselves in the cabinet. Then make appropriate arrangements for the safe disposal of the machine. For tank system machines ensure that any water is emptied out of the tank before it is moved.

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