Quality assurance
The following points should be observed to assist in maintaining quality standards
when reprocessing medical devices in order to protect patients and to avoid damage to
the loads being cleaned.
Only authorized personnel may interrupt a program in exceptional circumstances.
The standard of cleaning and disinfection in the disinfection programs must be routinely
confirmed by the operator. The process should be thermo-electrically tested on a regular
basis, and checked against documented control results.
For thermal disinfection, use temperatures and temperature holding times to achieve the
required infection prophylaxis in accordance with health and safety regulations.
Only reprocess undamaged and suitable items. When washing plastic items, ensure that
they are thermally stable. Nickel-plated items and items made of aluminum require
special procedures and are not generally suitable for machine reprocessing.
Items containing iron that can rust or corrode must not be added to the load or to the
wash chamber as contaminated items.
Under certain circumstances, process chemicals can result in damage to the machine.
Users are urged to follow the recommendations issued by manufacturers of process
chemicals.
Contact Miele in the event of damage and any suspicion of material incompatibility.
Instrument-care products based on paraffin oils (white oils) can damage the elastomers
and plastics in the machine. Such care products must not be dispensed as process
chemicals in this machine, even if they are recommended for machine use by the careproduct manufacturer.
Abrasive substances should not be introduced to the machine as these could cause
damage to mechanical components in the water circuit. Abrasive residues on the load
must be removed completely before reprocessing.
Pre-treatment with cleaning or disinfecting agents and certain types of soiling and
process chemicals can create foam. Foam can have an adverse effect on the disinfection
and cleaning result.
The reprocessing process must be set up to not result in foam being discharged from the
wash chamber. Foam discharge can compromise the operation of the machine.
The process used must be monitored on a regular basis by the operator to check
foaming levels.
Even when a process chemical, e.g. detergent, is recommended on technical application
grounds, Miele takes no responsibility for the effect of such chemicals on the load items.
Please note that changes in product formulation, storage conditions, etc., which are not
announced by manufacturers of process chemicals may impair the quality of cleaning
results.
PRODUCT INFORMATION
REV.0.01_COD.500291_A4

PRODUCT INFORMATION
When using process chemicals, always consult the instructions issued by individual
manufacturers. Process chemicals must only be used for the purpose they are designed
for by the manufacturer to avoid any material damage or the occurrence of very strong
chemical reactions (e.g. oxyhydrogen explosion).
Always follow the relevant manufacturer's instructions on storage and disposal of
process chemicals.
Particles ≥ 0.8 mm are removed by the filters in the chamber. Smaller particles may find
their way into the circulation system. For this reason, reprocessing loads with narrow
lumens requires additional filtering of the wash water.
In critical applications where very stringent requirements have to be met, it is strongly
recommended that all the relevant factors for the process (detergent, water quality, etc.)
are discussed with Miele.
Load carriers which hold the load must be used only as intended.
The interior of lumened items must be thoroughly flushed through with wash water.
Place small and light items in a mesh tray for small items so that they do not block the
spray arms.
Empty any containers or utensils before loading them.
The amount of solvent residues on the load items must be minimal when they are placed
in the wash chamber.
Solvents with a flash point below 21°C may only be present in trace amounts.
Chloride solutions, in particular hydrochloric acid, or corrosive iron materials must not be
placed in the wash chamber.
Ensure that solutions or steam containing chlorides or hydrochloric acid do not come into
contact with the stainless steel outer casing of the machine in order to avoid any damage
through corrosion.
After any plumbing work, the water pipework to the machine will need to be vented. If
this is not done, components can be damaged.
The gaps between a built-in machine and adjacent cabinetry must not be sealed, e.g.
with silicone sealant, as this could compromise ventilation of the circulation pump.
Follow the installation instructions in the operating and installation instructions.
Using accessories
Only use genuine Miele original spare parts and accessories suitable for the application
they are required for. Model designations are available from Miele.
Only use Miele wash carts, baskets, modules, and inserts. Using wash carts, baskets,
and inserts made by other manufacturers, or making modifications to Miele accessories
can result in unsatisfactory cleaning and disinfection result. Any resultant damage would
not be covered by the warranty.

3. INSTALLATION
3.1 Water connection
Water quality
The quality of the water used in all the cleaning stages is essential in achieving good results.
The water must be compatible with the material from which the machine is made.
The water must be compatible with process chemicals.
The water must be compatible with process requirements for the various stages of the
process.
In order to achieve good cleaning results, the machine requires a supply of soft water with a
low calcium content. Hard water results in the build-up of calcium deposits on the load and
on the inner walls of the wash chamber.
Water with a hardness level higher than 0.7 mmol/l (4 gr/gal) must be softened. This occurs
automatically during a program sequence on machines with a built-in water softener. The
water softener must be set to the exact hardness of the water.
The water softener must be reactivated at regular intervals. This requires the use of special
reactivation salt. Reactivation is carried out automatically during a program sequence.
INSTALLATION
Note: The water hardness is set by Miele Service.
WARNING
Water from the chamber is not suitable for drinking!
The machine must be connected to the water supply in strict accordance with local
regulations.
The water used must at least comply with national regulations for drinking water quality. If the
water supply has a high iron content, there is a danger of corrosion occurring on the load and
the machine itself. If the chloride content of the water exceeds 100 mg/l, the risk of corrosion
to the load in the machine will be further increased.
A backflow preventer is not required if national regulations permit; the machine is equipped
with a safety system for the protection ofdrinking water.
The machine is installed as standard with connections for cold and DI water. Connect the
inlet hoses to the shutoff valves for cold and DI water.
The minimum flow pressure is 100 kPa at the cold water connection and 30 kPa at the DI
water connection.
The recommended flow pressure is ≥ 200 kPa for the cold water connection and ≥ 200 kPa
for the DI water connection in order to avoid excessively long water intake times.
The maximum permissible static water pressure is 800 kPa.
If water pressure is not within the specified range, contact Miele Service for advice.
A booster pump is required if the flow pressure is below 200 kPa. If the pressure is higher
than 800 kPa, a pressure reducer must be installed.
A shutoff valve with a ¾” threaded union must be provided on-site. The valve must be easily
accessible to allow the inlet to be turned off when not in use.

BUILT-IN WATER SOFTENER
4.1 Refilling the salt
Use only special, coarse-grained reactivation salt or other pure evaporated salt. Never use
any other kind of salt, e.g. table salt, animal feed salt, or de-icing salt. Other salts may
contain insoluble additives which can impair the functioning of the water softener.
The following prompt reminds the user to refill the salt container:
“Refill salt”
The container for reactivation salt is located in the base of the wash chamber inside the
machine.
Open the door.
Remove the load carrier.
Unscrew the plastic cap on the container.
Fill the funnel with salt.
Raise the funnel by the handle and place it on the container.
Release the handle. The salt then passes from the funnel into the container.
Repeat the process until the container is visibly full.
The supply container contains approx. 780 g of salt.
WARNING!
The container must always be completely filled. If filled to less than full,
the water softening capacity is reduced and limescale deposits may
occur on the load and on chamber surfaces.
Refit the plastic cap on the salt container and screw tight.
Place the load carrier back into the machine.
Start the “Rinse” program.
WARNING!
Run the “Rinse” program after refilling the salt. This removes and
dissolves spillages of salt and brine. Excess salt and brine which has
overflowed can cause corrosion damage if they are not rinsed away.
WARNING!
During reactivation, the following appears on the display: “Reactiv.
pause”.

6.4 Preparation
Preparing the load
WARNING
Injector connections which are not used to clean handpieces must be
sealed using the caps provided.
New caps are available from Miele.
It is advisable to use only instruments made of stainless steel which is not susceptible
to corrosion.
Nickel and chrome-plated loads and items made of aluminum are not generally
suitable for machine reprocessing. They require special processing conditions.
Plastic items must be thermally stable.
Prior to loading the machine, remove materials such as composites, cement, and
amalgam in accordance with valid guidelines.
Handpieces with light guide rods can be regarded as durable, whereas fibre optic
bundles can be susceptible to more rapid wear.
Handpieces must only be reprocessed in special-purpose injection connectors with a
filter insert.
Only mildly alkaline or pH-neutral detergents must be used to reprocess handpieces
in order to avoid material degradation.
OPERATION
WARNING
A stainless steel filter insert must be installed on each connector used to
reprocess handpieces.
The filter is marked with “TOP”. The filter must be inserted into the
connector with the word TOP facing upwards.
The filter must be checked and cleaned daily.
Take apart any items which can be dismantled according to the manufacturer's
instructions and reprocess the individual parts separately from each other.
Only reprocess small items and micro components in special inserts, mesh trays with
lids, or mesh inserts.
Before machine reprocessing, check that the lumened instruments can be flushed
through and remove any possible blockages.
Load the machine and position items carefully in the holders.
Do not place items to be cleaned inside other pieces where they may be concealed.
Do not place items so close together that cleaning is hampered.
Arrange the load so that water can access all surfaces. This ensures that the load gets
properly cleaned.
Position load items such that fluids can drain off freely.
Position tall and heavy items towards the middle of the basket.
When loading the machine, make sure that nothing blocks the spray arms.
Distribute the load uniformly across the baskets.
REV.0.01_COD.500291_A4
