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.
–
Follow the instructions and
recommendations of the process
chemical manufacturers.
–
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.
– Follow the instructions and
recommendations of the process
chemical manufacturers.
– Carry out a regular visual check of
any accessible elastomers and
plastics for damage.
Hydrogen peroxide can release large
amounts of oxygen.
– 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 for advise.
The following chemical agents can
cause large amounts of foam to build
up:
–
Cleaning agents and rinsing agents
containing tensides.
Foam can occur:
–
in the program block in which the
chemical agent is dispensed,
–
in the following program block if it
has been spilt,
–
in the following program with rinsing
agent if it has been spilt.
–
Process parameters in the wash
program, such as dispensing
temperature, dosage concentration
etc. must be set to ensure the whole
process is foam free or very low
foaming.
–
Please observe chemical agent
manufacturer's instructions.
