Loading the machine
– Arrange the load so that water can
access all surfaces. This ensures
that it gets properly cleaned.
– Do not place items to be cleaned
inside other pieces where they may
be concealed.
– Hollow instruments must be
thoroughly cleaned, internally and
externally.
– Ensure that instruments with long
narrow hollow sections can be
flushed through properly before
placing them in inserts or connecting
them to jets.
– Hollow vessels should be inverted
and placed in the correct mobile
units, modules and inserts to ensure
that water can flow in and out of
them unrestricted.
A cover net can be used to reduce
the risk of glass breakage during the
wash process.
– 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 or being attracted by the
magnetic strip on the automatic
mobile unit recognition system.
– Deep-sided items should be placed
at an angle to make sure water runs
off them freely.
– Tall, narrow pieces should be placed
in the centre of the baskets. This
ensures good water coverage.
– Mobile units with an adapter must
engage correctly.
– Modules must be correctly
connected in the mobile unit.
– The spray arms must not be blocked
by items which are too tall or which
hang down in their path. If in doubt,
test for free movement by manually
rotating the spray arms.
– It is advisable to use only instruments
made of special application steel
which are not susceptible to
corrosion.
– Instruments which cannot withstand
high temperatures should be
chemically disinfected.
,
Disposable instruments must not
be put into the machine for
reprocessing.
The loading pattern as specified in
the validation procedure must be
meticulously maintained.
Preparing the load
Empty all containers before loading into
the machine (paying particular attention
to regulations regarding infectious
diseases and epidemics).
,
Ensure that acids and residual
solvents, especially hydrochloric
acid or chlorides, cannot get into the
wash cabinet.
Unloading instruments
Instruments should be unloaded dry
ready for further processing.
