Important information about routine operation
Please follow the current recommendations from the Robert Koch Institute (RKI) and the directions in DIN
58946-7 regarding routine operation.
Manufacturer’s recommendation for routine operation of class B
autoclaves
(in accordance with the current recommendations from the Robert Koch Institute)
When does testing need to
be done? How is testing done?
Once a working day Visual inspection of the door seal and the door closure for any
leaks.
Inspection of the operating media (electricity, feed water, water
connection where applicable).
Inspection of the documentation media (printer paper / computer /
network).
The steam penetration test with the Bowie - Dick test in the universal
program is recommended (test system in accordance with EN 867-5).
Once a week Vacuum test
Tip: In the mornings before starting work—the autoclave must be cold
and dry.
Batch-related tests For instruments in Critical B category:
the test set Helix test should be done together with every
sterilization cycle as a batch control.
For instruments in Critical A category:
a chemical indicator (class 5 as defined by ISO 11140) should be
included together with every sterilization cycle as a batch control.
For instruments in Critical A+B category:
The test set Helix test should be done together with every
sterilization cycle as a batch control.
This simplifies the workflow and increases the reliability. A daily steam
penetration test with the Bowie & Dick test (see above) can then be
omitted.
Another test system as defined by EN 867-5 can be used. Due to the
variety of test systems available, it is not possible for Sirona to provide
technical support for the use of another system.
WARNING
The results of the tests must be documented.
The used indicator test strips themselves do not have to be stored.

Chapter 4 – Sterilizing
14
Preparing the items to be sterilized
Follow the cleaning and care instructions of the manufacturer to prepare the items to be sterilized. This is a
prerequisite for both proper cleaning and disinfection and subsequent sterilization of the items to be
sterilized. The materials, cleaning agents, and preparation methods used are of critical importance.
NOTE
Sterilize textiles and instruments separately if possible in separate sterilizer containers or
sterilization wrap. This will achieve better drying results.
Preparing instruments
Pay attention to the following when preparing used and brand-new instruments:
It is essential that you follow the instructions of the instrument manufacturer when preparing and
sterilizing the instruments and comply with the relevant standards and directives, e.g., BGV A1, RKI,
and DGSV.
The instruments must be cleaned very thoroughly, e.g., with the help of a cleaning and disinfection
unit.
At the end of the disinfection and cleaning, rinse the instruments, preferably with demineralized or
distilled water, and then thoroughly dry the instruments with a clean, lint-free cloth.
Only use care products that are suitable for steam sterilization. Ask the manufacturer of the care
product.
DANGER!
As a result of incorrect preparation of instruments any residual soiling can become loose during
sterilization. Traces of disinfectant and cleaning agents lead to corrosion.
Unsuitable care agents, e.g., water-repellent care agents or oils that are impermeable to
steam, can lead to non-sterile instruments. This places your health and the health of your
patients at risk.
An increased need for maintenance and impaired function of the autoclave may result.
Therefore, it is essential that you follow the preparation instructions described in this manual.
When using ultrasonic units, cleaning equipment for handpieces and turbines, and cleaning and
disinfecting units, you must follow the preparation instructions of the instrument manufacturer.
Preparing textiles
When preparing textiles and when placing textiles in the sterilization containers, pay attention to the
following:
Follow the instructions of the textile manufacturer when preparing and sterilizing textiles and comply
with the relevant standards and directives, e.g., from RKI and DGSV.
Align the folds of the textiles parallel to one another.
Stack the textiles as vertically as possible and not too close to one another in the sterilization
container so that flow channels can form.
Keep the stacks vertical when you pack the textiles into the sterilization container.
If the textile packages do not stay together, wrap the textiles in sterilization paper.
Only sterilize dry textiles.
The textiles must not make direct contact with the floor and walls of the sterilization chamber because
otherwise they become saturated with condensate.

Chapter 4 – Sterilizing
15
DANGER!
The penetration of steam into the washing package can be hindered and/or you obtain poor
drying results. The textiles cannot be sterilized.
This could represent a risk to the health of the patient and the clinical team.
It is therefore essential that you follow the preparation instructions in this manual.
Loading the autoclave
Effective sterilization and good drying results can only be achieved when the autoclave is loaded correctly.
You must therefore pay attention to the following during loading:
Only place trays or cassettes with the corresponding rack into the chamber.
Use perforated trays such as the trays from MELAG. This is the only way to ensure the condensate
drains. If you use solid trays or open pans to hold the items to be sterilized, this may lead to poor
drying results.
Using tray inserts made of paper can also lead to worse drying results.
Wrapping
Only use wrapping materials and systems (sterile barrier systems) that comply with the DIN EN ISO
11607-1 standard.
The correct application of suitable wrapping is critical for the success of the sterilization.
You may use re-usable, rigid packaging such as standard tray cassettes or soft wrapping such as
transparent sterilization wrap, paper bags, sterilization paper, textiles or non-woven fabric.
Closed sterilization containers
When using closed sterilization containers to hold the items to be sterilized, pay attention to the following:
Use sterilization containers made of aluminum. Aluminum conducts and stores heat well and thus
accelerates drying.
Closed sterilization containers must have at least one side perforated—preferably on the bottom—or
have vents.
If possible, only stack sterilization containers of the same size on top of one another which allow
condensate to drain on the side facing the walls.

Chapter 4 – Sterilizing
16
WARNING
Using sterilization containers that are not suitable leads to insufficient stem penetration and the
sterilization may not be successful. The drainage of condensate may also be hindered.
Poor drying results are the consequence. This can ultimately lead to non-sterile
instruments and thus endanger the health of patients and the clinical team.
Closed sterilization containers must have at least one point—preferably on the bottom—with
perforations or vents.
WARNING
If the sterilization containers are stacked incorrectly, the dripping condensate cannot drain to the
floor of the chamber. It can saturate the items below.
Poor drying results are the consequence. Non-sterile instruments may result and these
can endanger the health of patients and the clinical team.
When stacking the containers ensure that the sterilization containers do not cover the
perforation.
Soft sterilization wrapping
Soft sterilization packages can be sterilized both in sterilization containers and on trays. Pay attention to
the following when using soft sterilization packages such as MELAfol:
Arrange the soft sterilization packages vertically and close together.
Do not lay several soft sterilization packages flat on top of one another on a tray or in a container.
If a sealed seam tears during sterilization, the packaging may have been too small. If this is not the
case, rewrap the instruments and sterilize them again.
If a sealed seam tears during sterilization, use a longer sealing time on the sealer or use a double
seam.
Multiple wrapping
Because the autoclave uses the fractionated pre-vacuum process, multiple wrapping can be used.

Chapter 4 – Sterilizing
17
Mixed loads
Pay attention to the following when sterilizing mixed loads:
Always place textiles on top.
Sterilization containers on the bottom.
Unpacked instruments on the bottom.
Transparent sterilization wrap and paper packages on top—the exception is when combining with
textiles, then on the bottom.
The heaviest items are on the bottom.
Stack transparent sterilization wrapping as upright as possible so that alternating paper side is against
paper side and film side against film side but if this is not possible then with the paper side facing
downwards.
