Action
The following substances can damage
the elastomer components (hoses and
seals) and the plastic components of
the machine:
– oils, waxes, aromatic and
unsaturated hydrocarbons,
– softeners,
– cosmetics, hygiene and skin care
products such as creams (analysis
and filling departments).
– Retrofit the machine with more
grease-resistant elastomers.
– Depending on what the machine is
used for, periodically wipe the lower
door seal with a lint-free cloth or
sponge.
Clean the wash compartment and
accessories without a load using the
ORGANICA program.
– To process the load, use the "OIL"
program (if available) or use the
special program with emulsifier
metering.
The following substances can cause
excessive foaming during washing and
rinsing:
– treatment agents such as disinfection
agents, rinsing agents, etc.
– reagents for analysis, e.g. for
microtitration plates,
– cosmetics, hygiene and skin care
products such as shampoos and
creams (analysis and filling
departments).
– foaming substances in general, for
instance tensides.
– First rinse the load with a sufficient
quantity of water.
– Select a wash program with one or
more short pre-rinses with cold or
warm water.
– Taking the specific application into
account, add an antifoaming agent,
one without silicone oils if possible.
The following substances can cause
corrosion of the stainless steel in the
wash compartment and accessories:
– hydrochloric acid,
– other substances that contain
chloride, e.g. sodium chloride, etc.
– concentrated sulphuric acid,
– chromic acid,
– iron particles.
– First rinse the load with a sufficient
quantity of water.
– Let the load drip dry before putting it
on the mobile units, baskets and
inserts and placing them in the wash
compartment.
