Chemical agents
Problem How to resolve it
De-foaming agents, especially silicone
based ones can cause the following:
–
deposits to build up in the cabinet,
–
deposits to build up on the load,
–
damage to elastomers and plastics
in the washer-disinfector,
–
damage to certain plastics (e.g.
polycarbonate and plexiglass) in the
load being reprocessed.
–
De-foaming agents should be used
in exceptional cases only, for
instance when absolutely essential
for the process.
–
The wash cabinet and accessories
should be periodically cleaned
without a load and without
de-foaming agent using the
ORGANIC programme.

Soiling
Problem How to resolve it
The following substances can damage
elastomers (hoses and seals) and
plastics in the washer-disinfector:
– oil, wax, aromatic and unsaturated
hydrocarbons,
–
emollients,
–
cosmetics, hygiene and care
products such as creams (analytical
applications).
– Refit the washer-disinfector with oil
resistant elastomers.
– Depending on usage wipe the lower
door seal on the washer-disinfector
periodically with a lint-free cloth or
sponge.
Clean the wash cabinet and
accessories without a load using the
ORGANIC programme.
–
Prepare the load using the "OIL"
programme (where this is available)
or use a special programme that
dispenses cleaning agents
containing tensides.
