Explanation
Messages A number of notifications are messages providing information.
Messages are not malfunction messages or warnings. They support
the operation of the steam sterilizer.
Warnings Warning messages are displayed when necessary. These contain
instructions which apply to you, the operator. Warning messages
are not malfunction messages. They help to ensure malfunction-
free operation and to recognize undesirable situations. Comply with
these warnings early in order to avoid malfunctions.
Malfunction messages Malfunction messages are issued when it is not possible to ensure
safe operation or safety of sterilization. These can appear on the
display shortly after switching on the device or during a program
run. If a fault occurs during a program run, the program will be
aborted. Aborting a program before the drying phase means that
the load is unsterile. If necessary, repack the load and repeat the
sterilization for the sterilization material affected.
WARNING
Danger of infection from early program abort
Aborting a program before the drying phase begins means that the load is unsterile. This
endangers the health of your patients and practice team.
n If necessary, repack the load and repeat the sterilization for the sterilization material
affected.
