instructions!

The machine must be installed,

maintained and repaired by a Miele Service Technician. For best compliance with Good Laboratory Practice and regulations governing the use of medical products, a Miele Ser vice and Repair Contract is recommended. Repairs by unqualified persons could be very dangerous!

Do not install the machine in an area

where there is a risk of explosion or freezing.

The electrical safety of this machine

is only assured if it is connected to a properly installed grounding system. It is imperative that this basic safety requirement is met. If there is any doubt, have the electrical system checked by a qualified electrician. The manufacturer will not be held liable for damages resulting from an inadequate grounding system (e.g. electric shock).

A damaged or leaking machine is

dangerous. Turn off the machine imme diately at the power switch and call the Miele Service Department.

Machine operators must be trained

on a regular basis. Untrained personnel must not be allowed access to the machine or its controls.

Safety instructions and warnings

Take care when handling

processing chemicals (detergents, softeners, neutralizers, rinsing agents, etc.). These may contain irritant or corrosive ingredients. Observe the applicable safety regulations! Wear protective gloves and goggles! Always follow the manufacturer's safety instructions and material safety data sheets when using processing chemicals.

The machine is only designed for

use with water and the recommended processing chemicals. NEVER use organic solvents or flammable liquids. These could cause an explosion or damage to rubber and plastic components, which results in leaks.

The water in the machine is not safe

to drink!

Do not stand, sit or lean on the

machine door when open. The appliance might tip over or be damaged.

Take care when loading standing

items with sharp pointed ends. Position them in the machine so that you will not hurt yourself or create a danger for others.

When operating this machine,

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 a risk of inhaling toxic vapors.

If toxic chemicals may be present in

the wash cabinet (e. g. aldehydes in the disinfectant), the door seal and, if applicable, the steam condenser must regularly be checked for soundness. Opening the washer door during a program interruption is particularly dangerous when toxic chemicals are present.

If you are exposed to toxic vapors or

processing chemicals, consult the manufacturer's material safety data sheets for emergency procedures.

Always allow baskets, inserts and

the washload to cool down. Empty any water from hollow items into the wash cabinet.

After drying with the drying unit,

leave the door open at first to allow the items, baskets and inserts to cool down.

Do not touch the heating elements

when you open the door during or at the end of a program. They remain hot for quite a few minutes after the program has ended and can cause burns.

NEVER hose down the machine or

the immediate vicinity, e.g., with a water hose or pressure washer.

Before servicing the machine,

disconnect it from the power supply.

Safety instructions and warnings

The following points should always be observed to assist in maintaining quality standards when processing medical devices and critical items, to protect patients and to avoid damage to property.

If the machine is being used for

decontamination ordered by the authorities, the steam condenser and its connections to the wash compartment and outlet discharge must be disinfected in the event of repairs or replacements.

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 are being met. Therefore, the processes need to be thermoelectrically tested on a regular basis and process results checked and documented. For thermo-chemical 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.

Disinfection programs that use a

chemical disinfectant at moderate temperatures (for example 65 °C or below) do NOT fulfill the requirement for mandatory decontamination under Section 18 of the IfSG. These programs should only be used when the items in question are temperature-sensitive. The disinfection parameters are based on the trials carried out by the disinfectant manufacturer. Always observe their specifications for handling, application conditions and efficacy. The operator is responsible for the use of any such thermo-chemical processes.

OR shoes should only be cleaned

and disinfected in a machine that has been installed for that purpose.

Under certain circumstances, the

processing chemicals can damage the appliance. Consult Miele Customer Service for recommendations. For concerns involving possible damage to the appliance or materials, please consult a Miele Application Specialist.

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 results obtained.

The process must be set so that no

foam escapes the wash compartment. Escaping foam impairs the safe operation of the machine.

The process must be checked

regularly in order to detect any foaming.

Safety instructions and warnings

In order to prevent damage to the

machine and any accessories through processing chemicals or dirt as well as any interaction between them, see the instructions in the section Chemical process.

Even when a certain processing

chemical is recommended, the appliance manufacturer takes no responsibility for the effect of such chemicals on the material of the items to be treated. Note that formulation changes, storage conditions, etc. that are not disclosed by the manufacturer may alter the cleaning results obtained.

When using processing chemicals,

it is essential that the manufacturer’s instructions are followed. Use the processing chemicals only for the applications intended by the manufacturer to avoid possible chemical reactions (such as explosive oxyhydrogen gas reactions).

For critical applications, where very

high processing-quality requirements have to be met, it is strongly recommended that all process-related factors (cleaning agents, water quality, etc.) be discussed in advance with Miele's Application Specialist.

The mobile units, baskets and

inserts must only be used for their specific applications. Hollow items must be positioned for full exposure to wash water.

Empty all containers and hollow

utensils before loading them.

Ensure that no acid or solvent

residues, especially hydrochloric acid or chloride solutions, get inside the wash cabinet. This also applies for corrosive ferrous material. Solvents combined with contaminants (especially from hazard class A1) should be present in trace amounts only.

To avoid corrosion damage, make

sure the stainless steel housing does not come into contact with solutions/steam containing hydrochloric acid.

Whenever work is conducted on the

tap water network, the water supply line to the machine must be cleared of air. Failure to do so can result in damage to the machine.

Please be sure to follow the

installation instructions in this manual and in the separate installation manual.

For applications that demand

especially stringent cleaning and rinsing, (e.g., chemical analysis, special industrial processes, etc.) the operator must perform quality control on a regular basis to ensure the required standard.

Safety instructions and warnings

Accessories

Whatever the application, only Miele

accessories should be connected to this machine. Consult a Miele Application Specialist for details on the type of equipment to use.

Only Miele mobile units, baskets

and inserts should be used. If Miele accessories are altered in any way, or equipment from another manufacturer is used, Miele cannot ensure the cleaning and disinfection results. Damage or injury caused in this way are excluded from the warranty.

Only use processing chemicals that

are approved by their manufacturer for the application involved. Any negative effects on items and the machine itself are the liability of the manufacturer of the processing chemicals.

Symbols on the appliance

Caution: Comply with the Operating Instructions!

Disposing of your old appliance

Old appliances may be

contaminated from exposure to blood or other body fluids and must therefore be decontaminated before disposal. For safety and environmental protection, be sure to drain/remove all processing chemical residue. (Comply with safety regulations and wear protective eyewear and gloves.) Remove or destroy the door latch, to prevent children from locking themselves inside. The appliance can now be sent for disposal through the proper resource recovery facilities. In the case of machines with a tank system, the water in the tank must first be removed.

The manufacturer will not be held liable for damage caused by failure to comply with the safety instructions and warnings.

Caution: Danger of electric shock!

Intended Use

Miele washer-disinfectors are designed to clean, rinse, disinfect (thermal/thermochemical) and dry re-usable medical devices, laboratory equipment and instrumentation. Whatever items are being processed, always comply with the particular manufacturer's instructions (EN ISO

17664).

Typical applications include:

surgical instruments,

–

endoscopic instruments,

–

– intensive care and anesthesiology

equipment,

– baby bottles and nipples,

– OR shoes,

– laboratory equipment for research

and production,

– laboratory equipment for analytical

and preparation applications,

–

microbiology and biotechnology labware.

Labware can include anything from evaporation dishes to centrifuge tubes.

In this operating manual, the general term labware is used to cover a range of equipment and items.

For standardized results, it is preferable to machine-wash lab 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. According to the A

concept described

in EN ISO 15883-1, thermal disinfection occurs at 80°C (+ 5 °C, - 0 °C) with 10 min holding time (A

600), or at 90°C

(+ 5 °C, - 0 °C) with 5 min holding time (A

3000), depending on the

disinfection result required. The efficacy standard A

3000 includes the

inactivation of HBV.

Regional and/or other official directives may apply (e. g., §18 of the IfSG for Germany).

The cleaning parameters should always be optimally matched to the type of soiling and labware involved. The processing chemicals used also should be matched to the particular cleaning needs / analysis / analytical methods involved.

Intended Use

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.

Also important for acceptable cleaning results is the use of suitable loading accessories (mobile carts, 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.

Opening and closing the door

Electric door lock

The machine is equipped with an electric door lock.

The door can only be opened when

the washer-disinfector is connected

–

to the power supply,

the "ON/OFF" I-0 button is pressed

–

and

no wash or disinfection program is

–

running.

Opening the door

^ Press the door 5 button, grip the

door handle and pull open the door.

Do not touch the heating

elements when you open the door at the end of a program. They remain hot for quite a few minutes after the program has ended and can cause burns.

How to use the emergency door release

The emergency release feature should only be used when it is not possible to open the door normally, e.g. in the case of a power outage. For all DESIN programs, please read the "Important safety information".

Press the "ON/OFF" I-0 button to

switch off the machine.

How to close the door

Lift the door upward and push it until it clicks shut.

Locate the ring for the emergency release cable (at the bottom of the machine, behind the service panel) and pull the ring downward to open the door.

Water softener

In order to provide good cleaning results, the machine requires a supply of soft water (water that is low in calcium and magnesium). If hard tap water is used, it can leave a white mineral deposit build-up on the labware and the machine itself. Therefore, tap water with a hardness of 4 °d (0.7 mmol/l) or more must be softened. The built-in water softener is designed for this purpose.

In order to function properly, the

–

water softener requires a supply of reactivation salt.

– The washer-disinfector must be

correctly programmed to match the hardness of the tap water supply.

– Your local water authority will provide

information about the hardness of the tap water in your area.

The factory default for the water softener is set to a hardness of 19 °d (3.4 mmol/l).

If the actual water hardness is different (even if it is below 4 °d), the factory default setting will need to be changed using the electronic control.

If the water hardness is known to fluctuate (e. g., 8 - 17 °d), always program for the highest value (in this instance 17 °d).

The built-in water softener can be programmed to settings from 1 °d to 60 °.

It is useful to make a note of the water hardness so that you can provide the service technician with this information in the event of any service calls.

Please note the water hardness in the space provided here:

°d

Water softener

Setting the water softener

Before using the machine for the first time, the programming must be set to the local water hardness(see "Programming manual", "Operating information / Regeneration").

Salt indicator

If the display shows NO SALT, the salt reservoir needs to be filled.

The water softener is automatically regenerated while the next program is running. The program display will show REACTIVATION during this process.

Filling the salt reservoir

Only special, coarse-grained reactivation salt*, with a grain size of 1-4 mm, should be used in this machine.

*Available from your Miele dealer.

Do not use other types of salt, e.g. table salt, agricultural or de-icing salt. These could contain components which are insoluble in water and could damage the water softener. If in doubt, consult Miele Technical Service.

The salt reservoir holds approximately

2.5 kg salt.

Inadvertently filling the salt

reservoir with detergent WILL damage the water softener. Before filling the reservoir, always make sure that you are using reactivation salt.

Remove the bottom basket from the machine.

Unscrew the salt reservoir cap.

Before filling the salt reservoir for the first time fill the reservoir with approximately 2.5 liters of water, so that the salt can dissolve properly. Once the washer-disinfector has been operated, there will always be enough water in the reservoir.

Place the funnel provided in place.

^ Carefully fill the reservoir with the

reactivation salt.

Some displaced water will run out - this is normal.

Water softener

Immediately after this step, start the

REMOVE SALT program, to remove any traces of salt from the inside of the machine.

Note: There may be a delay of a few minutes before the REMOVE SALT program starts due to the reactivation of the water softener.

Wipe any residual salt off the thread and seal of the reservoir.

Screw the cap on securely.

Automatic mobile unit recognition (AWK)

In Operating level C, the automatic mobile unit recognition (AWK) assigns a properly coded mobile unit to one of program slots 1 to 15.

The coding on the mobile unit and the program slot with the corresponding program must be matched up in the electronic control.

To do so:

Before each mobile unit is used for

the first time, it needs to be properly coded (see "Mobile unit coding"), and

assign the wash program for mobile

unit coding to the corresponding program slot.

For instructions on how to change program slots, refer to the "Programming manual", under "System function / Selector switch organization".

Before starting the program, it is essential to check that the program required for this mobile unit is the one shown in the display. Otherwise, inadequate cleaning and disinfection could result. Do NOT allow the programs for mobile units with automatic recognition (AWK, pre-set program slots) to be used interchangeably.

Mobile unit coding

The automatic mobile unit recognition feature assigns each mobile unit to a program slot. For this to work, the mobile units must be coded with a magnetic strip (with a bit combination). In operating level C, only the program assigned to the corresponding program slot is available for a given coded mobile unit.

When a coded mobile unit is inserted into the machine (make sure there are no small parts stuck to the magnetic strip) and the washer-disinfector door closes, the automatic recognition unit selects the assigned program.

Make sure that no metallic parts

or pieces are stuck to the magnetic strip, in particular the underside. Attached metallic objects can cause the coding to be misread or unreadable.

Use the 6 button to start the program.

The coding includes 5 bits:

–

Bits 1 to 4 determine the mobile unit code,

–

Bit 5 is for control purposes (parity bit).

Automatic mobile unit recognition (AWK)

Setting the mobile unit coding

To set or modify the coding for a mobile unit with automatic recognition (AWK), follow these steps:

^ Unscrew the AWK rail (Allen key) and

remove it from the holder.

The sum of the coding must be an even number.

If the sum of the coding is an odd number, you will see the message CHECK MOBILE UNIT RECOGNITION. If the mobile unit coding equals 0, you will see the message NO MOBILE UNIT RECOGNITION. In both cases, no program can be started. The mobile unit recognition must be re-set.

Remove the magnetic strip from the rail.

Automatic mobile unit recognition (AWK)

Set the coding for the program place.

Lay the rail in the holder and screw

into place.

The magnetic strip for washerdisinfector G 7835 and G 7836 must contain gray magnets.

Set the magnetic strip in the rail.

The magnetic strip must be placed in the rail in such a way that the set bit coding according to the table is visible through the round window in the rail.
