Connected processing chemicals
Effects Action
The ingredients of the processing
chemicals have a considerable effect
on the durability and functionality (feed
performance) of the metering systems.
The metering systems (feed hoses and
pump) are designed for a specific type
of processing chemicals.
General categories:
–
alkaline to neutral pH products,
–
acid to neutral pH products,
–
hydrogen peroxide.
–
Use only those processing chemicals
recommended by Miele.
–
Perform regular visual inspections of
the metering system.
–
Regularly check the feed
performance of the metering system.
The processing chemicals can damage
the elastomer and plastic components
of the lab washer and its accessories.
– Use only those processing chemicals
recommended by Miele.
– Perform regular visual inspections of
all visible elastomer and plastic
components.
The following oxidizing processing
chemicals can damage the elastomer
components (hoses and seals) and, in
some cases, the plastic components of
the lab washer:
–
nitric acid,
–
peracetic acid,
–
products containing active chlorine.
The washing temperature should not
exceed
– 122 °F (50 °C) for nitric acid,
– 95 °F (35 °C) for peracetic acid,
–
176 °F (80 °C) for products
containing active chlorine.
The following processing chemicals
can release large quantities of oxygen:
–
hydrogen peroxide,
–
peracetic acid.
–
Use only tested processes such as
OXIVARIO or OXIVARIO PLUS
(if available).
–
In the case of hydrogen peroxide,
the washing temperature should be
below 158 °F (70 °C).
–
Consult Miele.
