2.1 Correct application
This machine is used to reprocess laboratory glassware and laboratory utensils. The process
includes cleaning, rinsing and, where required, disinfection and drying. Due to the wide variety of
laboratory glassware and laboratory utensils on the market, it may be necessary in some cases to
establish whether the item is suitable for reprocessing in this laboratory glassware washer.
This will depend on its use and the type of soiling present as well as the disinfection parameters.
Please refer to the information provided by the manufacturer of the laboratory glassware and
laboratory utensils.
Laboratory glassware and laboratory utensils suitable for reprocessing include:
 Vessels such as test tubes, beakers, flasks, cylinders, etc.
 Measuring vessels such as measuring cylinders, pipettes, volumetric flasks, etc.
 Dishes such as Petri dishes, watch glasses, etc.
 Plates such as slides, sequencing plates, etc.
 Small items such as lids, spatulas, magnetic stirring rods, stoppers, etc.
 Other items such as funnels, pipe/hose pieces, etc.
EXAMPLES OF APPLICATION AREAS:
 Laboratories in schools, colleges, and universities
 Research, quality assurance, development, technology, and production
 Different areas of inorganic, organic, analytical, and physical chemistry
 Biology, microbiology, and biotechnology
 Hospital laboratories
Reprocessing conditions must be suitable for the wash items and for the type of stain. Process
chemicals must be suitable for the type of soiling and for methods of analysis being used.
The use of a suitable load carrier (mobile unit, basket, module, insert, etc.) is important to ensure
adequate reprocessing of the wash items.
The machine can be qualified for process validation.
WARNING
Improper use can lead to personal injury and damage to property.
Miele cannot be held liable for damage resulting from incorrect or improper
use or operation.

2.2 Safety instructions and warnings
This machine complies with all statutory safety requirements. Improper use can lead to personal
injury and damage to property.
Read the operating instructions carefully before using this machine. This will prevent both
personal injury and damage to the machine.
Keep these instructions in a safe place where they are accessible to users at all times.
Correct application
 Use of the machine is only approved for the applications stated in the operating instructions.
Conversions, modifications, and any other use are not permitted and could be dangerous.
The cleaning and disinfection processes are only designed for laboratory glassware and utensils
which are designated as reprocessable by the manufacturer. The information provided by the
manufacturer of the wash items must be observed.
Miele cannot be held liable for damage resulting from incorrect or improper use or operation.
 This machine is intended for indoor use in a stationary location only.
Danger of injury
Please pay attention to the following notes to avoid injury
 The machine may only be installed, commissioned, repaired, and maintained by Miele Service
or a suitably qualified service technician. A Miele service contract is recommended to avoid
downtimes and helps to optimize operating parameters. Incorrect repairs can cause considerable
danger to users.
 Do not install the machine in an area where there is any risk of explosion or of freezing
conditions.
 In order to reduce the risk of water damage, the area around the machine should be limited to
furniture and fittings that are designed for use in commercial environments.
 Some metal parts pose a risk of injury/being cut. Wear cut-resistant protective gloves when
transporting and setting up the machine.
 If the machine is built under a countertop, it must only be installed under a continuous
countertop run which is firmly secured to adjacent units to improve stability.
 The electrical safety of the machine can only be guaranteed when correctly grounded. It is
essential that this standard safety requirement is observed and regularly tested. If in any doubt,
please have the electrical installation inspected by a qualified electrician. Miele cannot be held
liable for the consequences of an inadequate grounding system (e.g., electric shock).
 A damaged or leaking machine can pose a threat to your safety. Always switch off a damaged
or leaking machine immediately and contact Miele Service.
 Machine operators should be instructed on the use of the machine and trained regularly.
Untrained personnel must not be allowed access to the machine or its controls.
 Only use process chemicals which have been approved by their manufacturer for the relevant
application. The manufacturer of the process chemicals is liable for any negative influences on the
material of the wash items and the machine.
 Exercise caution when handling process chemicals. Some chemicals may be caustic,
irritating, and toxic.
The relevant safety regulations and safety data sheets issued by the process chemical
manufacturers must be observed.
Wear gloves and protective goggles.
 The machine is only intended for use with water and suitable process chemicals. The use of
organic solvents or inflammable liquids is not permitted.

This could cause an explosion or damage rubber or plastic components in the machine and cause
liquids to leak out of it.
 The water in the wash cabinet must not be used as drinking water.
 Do not lift the machine by protruding parts such as the door handle or the opened service flap
as these could be damaged or torn off.
 Do not sit or lean on the opened door. This could cause the machine to topple over and
become damaged or cause you an injury.
 Be careful when sorting items with sharp, pointed ends. Position them in the machine so that
you will not hurt yourself or create a danger for others.
 Broken glass can result in serious injury when loading or unloading. Broken glass items must
not be processed in the machine.
 Please be aware that the machine may be operating at high temperatures. Deactivating the
lock to open the door can result in a risk of burning or scalding, or contact with corrosive
substances. Where disinfectant is in use, there is also a risk of inhaling toxic vapours.
 Should personnel accidentally come into contact with toxic vapours or process chemicals,
follow the emergency instructions given in the manufacturer's safety data sheets.
 Load carriers such as baskets, mobile units, and inserts must be allowed to cool down before
they are unloaded. Any water remaining in containers should be emptied into the wash cabinet
before removing items.
 Never clean the machine or near vicinity with a water hose or a pressure washer.
 The machine must be disconnected from the electricity supply before any maintenance or
repair work is carried out.
