
Arrange soft sterilization packages vertically and side-by-side. This allows condensation to
penetrate to the packages, while at the same time preventing possibly bursting at the seams.

Do not allow bags and chamber inside touch each other.

Do not arrange packages as stacked.

Insert tools into separate bags.

While loading paper/plastic sterilization bags, place paper side of a paper/plastic bag towards
paper side of the other bag. Place plastic side of paper/plastic bag toward plastic side of
other bag.

Ensure that space shall be left between sterilization bags.

OPERATING PRINCIPLES
6.1.
OPERATION PHASES
PRE-VACUUM: As soon as the program is started, the pre-vacuum phase starts to operate.
Pressure in the chamber decreases below ambient pressure by vacuuming the air in the
chamber and steam is blown in to replace the volume of vacuumed air. This phase is repeated
several times depending on the selected program.
HEATING: Steam is charged to the chamber to reach sufficient steam temperature before
sterilization phase.
STERILIZATION: The chamber temperature is kept at the required sterilization degree all
through the sterilization phase.
STEAM DISCHARGE: The pressure in the chamber is decreased to the ambient pressure by
discharging the steam in the chamber after the sterilization phase.
DRYING: Following the steam discharging, the pressure in the chamber is decreased below
ambient pressure. Thus the humidity within the chamber is eliminated throughout the drying
phase.
AIR INTAKE: Following the drying phase, ambient air passing through the filter is taken into the
chamber to break the vacuum and raise the chamber pressure to ambient pressure.

If the lid is not opened after the program is over, another program cannot be started.

When sterilization is completed, condensate may be observed on the sterilized items.
However, it does not show that the sterilization is unsuccessful. The German
standard ‘DIN 58953’ Part 7 Section 7 comments on: “...Small amounts of water on
the surface of packages do not represent a cause for concern if they dry completely
within thirty minutes after removal from a steam sterilization system...”
