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 loads being
cleaned.
Only authorised personnel may interrupt a programme 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 current health and safety regulations.
Only reprocess undamaged and suitable items. When washing plastic items, ensure that they
are thermally resistant. Nickel-plated items and items made of aluminium 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 chamber as wash items or soiling.
Under certain circumstances, process chemicals may damage 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 agents containing chlorine can damage the elastomers of the machine.
If cleaning agents containing chlorine have to be used, a maximum temperature of 70 °C in the
“Main wash” programme blocks is recommended (see programme chart).
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 load must be
removed completely before reprocessing.
Pre-treatment with cleaning or disinfecting agents, some types of stains 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 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, 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.
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, such as detergents, 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 load must be used only
as intended.
Lumened items must be thoroughly cleaned, internally and externally.
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.
The amount of residual solvents on items going into the wash chamber should be minimal.
There should be no more than a trace of any solvents with a flash point of below 21 °C.
