Warning and Safety instructions
16

Where a chemical agent is recommended on technical application
grounds (e.g. a cleaning agent), this does not imply that the
manufacturer of the machine accepts liability for the effect of the
chemical on the items being cleaned.
Please be aware that changes in formulation, storage conditions etc.
which may not be publicised by the chemical manufacturer, can have
a negative effect on the cleaning result.

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 chemical agents.

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 chemical agents, water quality etc. are discussed
with the Miele Application Technology specialists.

If the cleaning result is subject to particularly stringent
requirements, e.g. in chemical analysis, the operator must carry out
regular quality control to ensure that required standards of cleanliness
are being achieved.

The mobile units, baskets, modules and inserts that hold the load
must be used only as intended.
Hollow 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 and acids on items going into the
cabinet should be minimal.
There should be no more than a trace of any solvents with a flash
point of below 21 °C.

Chlorous solutions, in particular hydrochloric acid, must not be
placed in the cabinet.

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 filled e.g. with silicone sealant as this could compromise the
ventilation to the circulation pump.
