Quality assurance
The following points should be observed to assist in maintaining quality standards when
reprocessing laboratory glassware and utensils and to avoid damage to the wash items
being cleaned.
Only authorized personnel may interrupt a program in exceptional circumstances.
It is the responsibility of the operator to demonstrably ensure reprocessing standards in
routine operation. Process results must be inspected and documented on a regular basis.
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. Ferrous materials that can rust or
corrode must not be introduced into the wash cabinet as wash items or as stains.
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.
Cleaning detergents containing chlorine can damage the elastomers of the machine.
If the use of cleaning detergents containing chlorine is required, a maximum temperature of 70°C
(158°F) is recommended for the main wash program blocks (see program chart).
In machines equipped with special oil-resistant elastomers (from the factory) for oil and grease
applications, cleaning detergents containing chlorine may not be used!
Abrasive substances should not be introduced into the machine as these could cause
damage to mechanical components in the water circuit. Abrasive residues on the wash items
must be removed completely before reprocessing.
Pre-treatment with cleaning or disinfecting agents,certain types of soiling and the interaction
of certain process chemicals can create foam. Foam can have an adverse effect on the
disinfection and cleaning result.
Reprocessing should not result in foam being discharged from the wash cabinet. 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 wash 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.
Always follow the relevant manufacturer's instructions on storage and disposal of process
chemicals.
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.
If the cleaning result is subject to particularly stringent requirements (e.g., chemical analysis),
regular quality control should be carried out by the operator to ensure that required standards of
cleanliness are being achieved.
Load carriers such as mobile units, baskets, and inserts which hold the wash items must be
used only as intended.
The interior of lumened items must be thoroughly flushed through with wash water.
Secure small and light items with cover nets or place in a mesh tray for small items, so that
they do not block the spray arms.
Empty any containers or utensils before loading them.
