Miele G 7883 Operating Instructions Manual page 20

Areas of application
– Hollow vessels should be inverted
and placed in the correct baskets
and inserts to ensure that water can
flow in and out of them unrestricted.
– Deep-sided items should be placed
at an angle to make sure water runs
off them freely.
– Tall, narrow, hollow items should be
placed in the centre of the baskets to
ensure better water coverage.
– Lightweight items should be secured
with a cover net (e.g. an A 6) and
small items placed in a mesh tray to
prevent them blocking the spray
arms.
– Mobile units or baskets with an
adapter must engage correctly.
– The spray arms must not be blocked
by items which are too tall or which
hang down in their path.
– It is advisable to use laboratory
utensils made of surgical steel only,
as these are not susceptible to
corrosion.
– Nickel-plated laboratory utensils and
coloured anodised aluminium
laboratory utensils are not suitable
for machine processing.
– Plastic items must be thermally
stable.

Preparing the load
^ Empty all containers before loading
into the machine (paying particular
attention to regulations regarding
infectious diseases and epidemics).
^ Remove culture medium (agar) from
Petri dishes.
^ Pour away blood or other body fluids,
and remove any dried on blood.
^ Remove all stoppers, corks, labels,
sealing wax residues, etc.
,
Ensure that acids and residual
solvents, especially hydrochloric
acid or chlorides, do not get into the
wash cabinet.
In certain cases, soiling that is difficult
or impossible to remove, e.g. silicone
grease, sticky labels, etc., which could
affect the cleaning results, must be
removed manually before being
machine processed.
It is the user's responsibility to decide
whether items contaminated with
substances such as microbiological
material, pathogens, facultative
pathogens, genetically modified
material etc. should be sterilised before
being machine processed.
Contaminated laboratory glassware
and utensils can be placed directly in
the baskets or inserts in the machine
without pre-treatment (no soaking
required).
