Chemical agents
Problem How to resolve it
The ingredients in chemical agents
have a strong influence on the longevity
and functionality (throughput) of the
dispensing system. The dispensing
system (hoses and pumps) should be
set up for a particular type of chemical
agent.
General types:
– Alkaline to pH neutral products,
– acidic to pH neutral products,
– hydrogen peroxide.
– Use Miele approved chemical agents
in this machine.
– Carry out a regular visual check of
the dispensing system for any
damage.
– Regularly check the flow rate of the
dispensing system.
Chemical agents can damage
elastomers and plastics in the
washer-disinfector and accessories. – Use Miele approved chemical agents
in this machine.
– Carry out a regular visual check of
any accessible elastomers and
plastics for damage.
The following oxidising chemical agents
can damage elastomers (hoses and
seals) and plastics in the
washer-disinfector:
– Nitric acid,
– peracetic acid,
– products containing active chlorine.
The wash temperature should be
limited to:
– 50 °C Nitric acid,
– 35 °C with peracetic acid,
– 80 °C with products containing
active chlorine.
The following chemical agents can
release large amounts of oxygen:
– Hydrogen peroxide,
– peracetic acid.
– Only use approved processes such
as OXIVARIO or OXIVARIO PLUS.
– The wash temperature must be less
than 70 °C when using hydrogen
peroxide.
– Please contact Miele Service or your
Miele Application Professional for
advice.
