Preparing the
load
Empty all containers before loading into the machine (paying
particular attention to relevant regulations).
Remove non-water soluble residues such as paint, adhesives and
polymer compounds using appropriate solvents.
Rinse wash load items which have been in contact with chloride
solutions or hydrochloric acid thoroughly with water before loading
in the machine and drain well.
The amount of residual solvents and acids on items going into
the cabinet should be minimal.
There should be no more than a trace of any solvents with a flash
point of below 21 °C.
Chloride solutions, in particular hydrochloric acid, must not be
placed in the cabinet.
Scoop nutrient media (Agar) out of petri dishes.
Shake out any blood residues and remove any clots.
If necessary rinse the wash load briefly with water to prevent coarse
soiling entering the machine.
Remove stoppers, corks, labels, sealing residues, etc.
Secure small items, such as stoppers and taps in suitable baskets
for small items.
It may be necessary in individual cases to check whether extremely
stubborn contamination e.g. vacuum grease, paper labels, etc. which
could affect the cleaning result, must be removed in advance.
It must be determined whether wash load items which are
contaminated with microbiological material, pathogenic germs,
facultative pathogenic bacteria, genetically modified material etc.
need to be sterilised prior to machine reprocessing.
