Program run
A program runs in three main phases: the air removal and heating up phase, the sterilization phase and
the drying phase. After program start, you can follow the program run on the display. It shows the chamber
temperature and pressure as well as the time until the end of sterilization / drying.
Air removal and heating up phase
During this phase, the steam will be injected and removed from the sterilization chamber (conditioning) to
generate over-pressure which removes residual air. Then, during fractionation, the mixture of air and
steam is evacuated from the sterilization chamber and steam is injected. This reduces the level of residual
air in the sterilization chamber to a minimum. At the same time, the requirements for pressure and temper-
ature are created for sterilization.
Sterilization phase
In the sterilization phase, pressure and temperature are held in the area required for sterilization.
The display indicates whether the sterilization phase has been completed successfully. The coloured ring
and the LED status bar switches from blue to green as soon as the drying phase has been introduced.
The sterilization phase is unsuccessful if the operator or the system (responding to an malfunction) aborts
the program run. A system abort returns the steam sterilizer to a pressureless state. This explains why a
system abort takes longer than an abort by the user.
Drying phase
The steam sterilizer provides excellent drying of the load. Depending on the setting, drying is performed ei-
ther via the time-controlled drying or the pre-set intelligent drying (see
[
page 56]). If dif-
ficult-to-dry items require better drying, you can undertake the following steps to improve drying:
u
Load the steam sterilizer properly. Stand e.g. the transparent and paper sterilization packaging
upright. Comply with section
[
page 24]. Use the optional package holder
if necessary.
u
Time-controlled drying: Activate function
Additional drying
, to extend the drying time by 50 %.
u
Intelligent drying: Activate function
Additional drying
to restrict the criteria for ending the drying
phase.
Following the program run on the computer
You can follow the current progress of a sterilization program on every computer in the practice network.
ü
The steam sterilizer has been assigned an IP address and is integrated in the practice network.

Open a web browser (we recommend Mozilla Firefox
or Internet Explorer/Microsoft Edge) and enter the IP
address of the steam sterilizer in the address bar of
the web browser e.g. 192.168.57.41.
