After the last vacuum phase, the pressure in the sterilization chamber must rise to the value
set for the sterilization process (3rd PRESSURE PULSE), always through the injection of
steam.

When the pressure and temperature values for the selected program have been reached, it is
a good idea to wait a moment to allow the temperature in the chamber and the load to stabilize
(EQUILIBRATION). The liquid crystal display shows:

2 . 1 5 b a r 1 3 : 4 0
When the thermodynamic parameters are balanced, the actual sterilization phase of the
materials begins (HOLDING TIME).
Thanks to continuous monitoring of the thermodynamic parameters and sophisticated
management of the plumbing circuit, the pressure and temperature are maintained constant
within the limits required by the program. A countdown begins of the sterilization time. The
display shows the following:
1
1 3 4 ° C P O R O U S

1 3 5 . 6 ° C 0 4 : 0 0
2 . 1 6 b a r 1 3 : 5 5
The icon for the sterilization process status
flashes to indicate that the treatment of the
load is in progress.
At the end of the sterilization phase, the icon
remains steady on to indicate the complete
sterilization of the material in the sterilization chamber.
WARNING
IF, FOR SOME REASON, THE STERILIZATION CYCLE HAS BEEN
INTERRUPTED BEFORE COMPLETION, THE ICON CONTINUES
FLASHING.
IN THIS CASE, THE MATERIAL CANNOT BE CONSIDERED STERILE AND
MUST ABSOLUTELY NOT BE USED.
At the end of the sterilization phase, the steam is released from the sterilization chamber
(STEAM DISCHARGE). The liquid crystal display shows:
1
1 3 4 ° C P O R O U S

The icon for the sterilization process status
is steady on.
