IMPORTANT SAFETY INSTRUCTIONS
Under certain circumstances, some cleaning agents can cause damage to the appliance. Consult the cleaning agent manufacturer for recommendations. For concerns involving possible damage to the appliance or materials, please contact Miele.
For critical applications where very high processing quality requirements must be met, it is strongly recommended that all process-related factors (cleaning agents, water quality, etc.) be discussed in advance with Miele.
Pre-treating (e.g. with cleaners or disinfectants) as well as some types of soiling and the interaction of cleaning agents can cause foaming. Foam can have an adverse effect on cleaning and disinfection.
Use mobile units, baskets and inserts only as instructed by the manufacturer.
Hollow items must be positioned so they receive full exposure to wash water.
Some disinfectant can denaturate proteins which has an adverse effect on cleaning. Please only use non foaming and non denaturation cleaners or disinfectants for manual prewash.
To prevent damage to the
washer-disinfector and accessories from the effects of cleaning agents only use chemical agents which have been approved by their manufacturer for use in the application you are using. Miele can recommend suitable products.
Even when a cleaning agent is recommended, the appliance manufacturer takes no responsibility for the effect of such chemicals on the items being washed.
Note that formulation changes, storage conditions, etc. that are not disclosed by the manufacturer may adversely affect the cleaning results.
Always follow the manufacturer’s instructions when using cleaning agents. To avoid possible chemical reactions, only use cleaning agents for the applications and purposes intended by their manufacturer.
Empty all containers and hollow items before loading them in the washer.
Ensure that no acid or solvent residues, especially hydrochloric acid or chloride solutions, get inside the wash cabinet. Any items that can rust should also be avoided.
Any solvents used should not be present in more than trace amounts.
To avoid corrosion, ensure that the stainless steel exterior does not come into contact with solvents containing hydrochloric acid / vapors.
Whenever work is conducted on the water supply, the supply lines to the washer must be bled.
Failure to do so can result in damage to the appliance.

Intended use
This washer-disinfector can be used to clean, rinse, intermediate-level thermally disinfect, and dry a wide range of reusable medical devices in hospitals, surgery centers, and clinics. Always follow the surgical instrument manufacturer’s instructions for machine-based cleaning. This washer-disinfector provides an automated process for the initial steps of cleaning and intermediate-level disinfection of re-useable surgical instruments prior to sterilization. The G 7899 is designed for applications such as:
General Surgical Instruments
Reusable, hard-surfaced surgical instruments such as scissors, forceps, etc.
Stainless steel lumened instruments. These can be processed but must be connected to Miele injection ports according to loading instructions provided with the specific Miele accessory.
Minimally Invasive Surgical (MIS)
Instruments
Rigid endoscopes
Note: The G 7899 is NOT intended for reprocessing of flexible endoscopes of any kind.
Containers and utensils
Such as kidney dishes, sterilization containers, trays, etc.
Microsurgical Instruments
Such as instruments used in eye surgery
When processing instruments in the Miele washer-disinfector you must:
Follow the instrument manufacturer’s instructions for cleaning and disinfection. Instruments must be disassembled according to the manufacturer’s instructions
Follow Miele instructions for proper loading (included with specific accessories and in the “applications” section of this manual). Proper instrument loading and connection of lumened instruments to injection ports is required
This washer-disinfector is intended to provide the initial step in reprocessing of soiled, re-usable medical devices. Any devices that contact blood or compromised tissues must be sterilized prior to re-use following industry best practices such as AAMI ST79.
9
Intended use
Processing instruments by machine achieves reproducible results with less opportunity for human error when compared with to manual cleaning. Thermal disinfection can be carried out using the Vario TD program which meets the parameters to achieve intermediate-level disinfection.
The cleaning program as well as chemical agents must be chosen according to the type of soil and load being processed.
Medical devices are best processed using the Vario TD program. The final result will be instruments that are clean, free of residue, and ready for subsequent sterilization. Only then can the instruments be safely used.
The use of a suitable load carrier (basket, module, insert, etc.) is important to ensure the adequate cleaning of the load. Examples are given in the “Applications” section.
The washer-disinfector can be programmed to perform the final rinse with tap water, or with purified water of a quality to suit the application (de-ionized, de-mineralized, reverse osmosis (RO), distilled). We recommend the use of purified water.
All instruments and accessories cleaned in the washer-disinfector (with the exception of non-critical items) must be sterilized before use.

Water softener
Filling the salt reservoir
Only use reactivation salt with granules of approx. 1 - 4 mm. Do not use other types of salt such as cooking salt, agricultural grade or road salt. These may contain insoluble additives which can impair the functioning of the water softener. If in doubt please contact Miele.
Reactivation salt can be ordered directly from Miele.
Remove the bottom basket from the machine.
Unscrew the salt reservoir cap.
Before filling the salt reservoir with reactivation salt for the first time, you will have to fill the reservoir with approx. 2/3 gal (2.5 liters) of clean water to enable the salt to dissolve. Once the machine has been used, this will no longer be necessary.
The salt reservoir holds approx. 2.5 kg of salt.
Inadvertently filling the salt reservoir with cleaning agent will damage the water softener. Before filling the salt reservoir make sure that there is no fluid covering the salt reservoir cap.
|
Place the provided funnel in position. |
|
Fill carefully with salt. |
As it is poured in, displaced water will run out.
16
Water softener
Add salt indicator
Remove the funnel and wipe any residual salt off the seal and the screw threads.
Screw the cap back on firmly.
Run the “Rinse” program to remove any traces of salt from the cabinet.
The program sequence may be delayed for a few minutes after the start of the “Rinse” program. This is normal as the water softener is being reactivated.
Reactivation will take place automatically when needed prior to the start of your selected program. The “Recharging” indicator lamp will be lit during this process.
Add salt when the “Recharge Softener” indicator lights up.
17
Applications
This washer-disinfector normally requires a top and bottom basket. Various inserts and special baskets are available for a wide variety of instruments and utensils.
Select baskets and inserts which are appropriate for the application.
Applications and loading examples are given on the following pages.
Before starting a program, visually check the following:
–Is everything correctly loaded/connected?
–Are the lumen or necks of hollow instruments positioned so that water can access them unhindered?
–Are the spray arms clean and do they freely rotate?
–Are the filters clean? Remove any coarse soils and clean them if necessary.
–Is the adapter connecting the water supply to the spray arms/jets connected correctly?
–Are all chemical containers sufficiently filled?
At the end of each program:
–Visually check the load for cleanliness.
–Check that all hollow shafted instruments are still securely positioned on their jets.
Any hollow instruments that have become disconnected from their adapters during processing must be processed again.
–Check that the lumen of hollow instruments are free of obstruction.
–Check that jets and connectors are securely in position in the baskets or inserts.
Verification testing
For verification of the cleaning process, periodic testing as outlined in current best practices documents such as AAMI ST79 is highly recommended. While Miele washers automatically monitor critical parameters such as time, temperature and dispensing, periodic verification to ensure proper soil removal should be part of your quality and safety program.
Miele also offers process documentation to support your periodic verification.

Applications
Loading the machine
–For proper cleaning, arrange the load so that water can access all surfaces.
–Do not place items inside other pieces where they may be concealed.
–Hollow instruments must be throughly 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 baskets or inserts to ensure that water can flow into and out of them unrestricted.
–Large or concave items should be placed at an angle to make sure water runs off them freely.
–Tall, narrow, hollow items should be placed in the center of the baskets to ensure better water coverage.
–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 from bouncing around or blocking the spray arms.
–The spring adapter of the mobile units or baskets must be correctly engaged.
–The spray arms must not be blocked by items which are too tall or which hang down in their path.
–Only process instruments made of surgical steel, as these are less susceptible to corrosion.
–Nickel plated instruments, colored anodized aluminum instruments, or disposable instruments are not suitable for machine reprocessing.
Preparing the load
Empty all containers before loading them into the machine.
Ensure that acids and residual solvents, especially those containing hydrochloric acid or chlorides, do not get into the wash cabinet.
Loading instruments
Contaminated instruments can be placed directly in the machine without pre-treatment (no soaking required). Always refer to the surgical instrument manufacturer’s instructions for cleaning.
Chemically pre-treated instruments must be thoroughly rinsed before placing them in the machine.

Applications
Surgical instruments
Surgical instruments should be stored for as short a time as possible before cleaning them.
Disinfection of surgical and minimally invasive instruments is performed thermally, after they have been cleaned. Deionized water should be used for the final rinse to help prevent spotting and corrosion.
More information regarding the water quality you can find in the AAMI publication TIR34:2007
Open up any hinged instruments and place them in mesh trays so that they are not touching each other.
Instruments with very narrow lumen must be manually pre-rinsed where necessary. Follow the manufacturer’s instructions on how to process them.

Applications
To avoid injury from instruments that are pointed at both ends or standing instruments with upward-facing probes, the washer should be loaded from back to front, and unloaded from front to back.
The O 177/1 Top basket and E 337/1 insert come with their own instructions for use.
O 177/1 Top injector basket
The left side of the O 177/1, has a retaining grid with 28 jets in silicone receptacles for hollow-bodied instruments. The jets spray the wash water directly into the instrument so that the recesses can be thoroughly flushed, cleaned, and disinfected.
Depending on the items to be cleaned, special nozzles, bushings or adapters are required. Further information can be obtained from the Miele Professional Sales Department.
The right side of the O 177/1 is left free to hold various inserts, such as the
E 337/1 (shown) for standing instruments.
24
Applications
Rigid Endoscopy
O 176/1 Top Injector Basket
Please note that the washer disinfector is designed for RIGID Endoscope cleaning and disinfection only. The endoscopes must first be disassembled for the best cleaning results. Always consult the manufacturer’s instuctions before processing any instrument in the washer-disinfector.
To ensure that water can flow in and out of the hollow parts of instruments, remove any caps and/or seals. Open valves and arrange according to the manufacturer’s instructions.
The left hand side of the basket is left free for inserts, such as the E 379.
This basket should be loaded only with slightly contaminated items.
To minimize the risk of injury from instruments that have a probe at the end, the washer should be loaded from back to front and unloaded from front to back.

Applications
Ophthalmology
The “C - Ophtha” program is especially designed for ophthalmic applications. This program has an additional rinse which uses deionized water.
This program is locked at the factory. To unlock this program please contact Miele Technical Service.
To prevent cross contamination of lumen or hollow items, the treatment of ophthalmic instruments should only be performed in a washer-disinfector designed for this application. Also, do not use plastic fiber cover nets (Miele nets A2 or A3) at any time in a washer disinfector that is also used for ophthalmic instrument processing.
Do not use Rinse Aid or any other rinsing agents when processing ophthalmic items.
The E 429 mobile injector can be used to clean and disinfect surgical, ophthalmic instruments used in the OR.
The top of the injector unit has connections for hollow instruments such as rinsing or suction hand pieces and cannulae, as well as silicone holders that are used to secure the instruments to their hose connections.
The lower level of the E 429 mobile injector can accommodate E 441/1 inserts or E 142 mesh trays that can be used for holding solid bodied instruments.
The E 429 mobile injector unit for surgical ophthalmic instruments comes with its own operating instructions.
Use of the E 429 requires a modification to the water intake path inside the wash chamber. This means that the E 429 cannot be used interchangeably with other mobile units or baskets.
