Operative Instructions
washing all residues well (e.g. disinfectant solutions)
in cold water.
- Remove non-water soluble residues such as
composites, cement and amalgam in compliance with
current directives.
- Insert the individual instruments in the appropriate
supports or baskets and never directly into the base
basket.
- If necessary rinse the wash load briefly with water to
avoid introducing coarse soiling into the machine.
- Remove all stoppers, corks, labels, sealing wax
residue, etc.
- Make sure that the instruments do not come out of
the containers.
- Make sure that the instruments do not fall off the
racks and inserts and do not hang from the grid bars.
- Insert the hollow instruments into the appropriate
injectors.
- Insert the other instruments into the adapters with
silicone insert.
- Check that injector and connectors are securely held
in position in the baskets or inserts.
- Position container-shaped objects so that liquids can
flow easily and, if possible, place tall and heavy tools
in the centre of the rack.
- Place pointed or sharp objects in such a way as to
prevent anyone from being injured by them.
a
WARNING! Sharp or pointed objects can
result in serious injury when loading or
unloading
- Components with special geometries must be
arranged so as to allow the water to flow out.
- Introduce only suitable steel instruments, resistant to
corrosion.
- Objects made completely or partially of plastic must
be resistant to high temperatures.
- Nickel-plated and chrome-plated and/or aluminium
instruments and tools may not always be suitable
for machine treatment. They require special process
conditions.
- If possible, disassemble the modular instruments
following the manufacturer’s instructions and treat
the individual parts separately.
- Transmission instruments with fibre optic rod are
considered resistant, while fibre optic beams may be
subject to premature wear.
- Treat small instruments and parts in special inserts or
closable baskets.
- Before the automatic treatment, check that the
lumen and hollow body instruments can be treated
internally and remove any obstructions.
- Carefully place the load in the supports.
- Objects must not be put inside each other nor cover
each other. Do not place objects so close to each
other that they cannot be washed properly.
- Arrange the load so that all surfaces can be reached
by the washing liquid. Otherwise they will not be
cleaned!
- Place the objects so that the liquids can flow out
without hindrance.
- Tall, narrow, hollow and heavy items should be placed
in the centre of the rack. This will ensure better water
coverage.
- When arranging the load, make sure that the spray
arms are not blocked by the load itself.
- After treatment, the transmission instruments
must be cleaned according to the manufacturer's
instructions. After treatment, before reusing the
transmission instruments, check that they are
working properly, e.g. by spraying liquids into the sink.
6.2.3 Summary of the rack loading operations
Depending on the load, special nozzles or adapters may
be required for proper internal cleaning.
Sequence for loading the rack/trolley:
1) Fill the rack/trolley by arranging the instruments so
that all surfaces are reached during washing.
2) Insert the rack/trolley into the chamber.
3) Close the door and start the washing program.
Handpieces
Handpieces must be washed and rinsed both internally
and externally. For this purpose, they require the use of
racks/trolleys with special injections.
Trays
Trays must be positioned in the specific slots of the tray
holder insert.
6.2.4 Treatment of dental instruments
a
WARNING!
Insert
only
instruments
suitable for automatic treatment in
washer disinfector, according to the
manufacturer’s instructions. In particular,
follow the information provided by the same
manufacturer. Despite compliance with
the manufacturer’s instructions, in case of
damage or alteration of the instruments,
the responsibility will be borne by the
instruments manufacturer.
Before starting the treatment, check that:
- The external surface of the instruments is clean of
material residues (E.g. dental cement, etc.).
