Select additional drying
For difficult drying tasks you can extend the drying time of a program by
50% with the function Additional Drying.
For this proceed as follows:
ƒ When starting the program, simultaneously press the K
EY
(S)
AND
K
EY
(+).
The display shows
Supplement drying selected
. Then the program
sequence begins.
Start program
If you have selected a program with the program selection button, in
addition to the selected program the sterilization temperature is displayed
and whether the respective program for packaged or unpacked sterilizing
materials is suitable.
ƒ Press the K
EY
(S), in order to start the program.
The autoclave checks the transport of the → feed water and its
→ conductivity.
If the Quick program is started, the warning text
Warning only
unwrapped instruments
is shown on the display.
ƒ If the load exclusively contains unwrapped instruments, press the Key
(S) once again to confirm and start the program.
Program is running
After the start of the program you can track the program steps on the
→ display. Chamber temperature and pressure as well as the duration until
the end of sterilization or the expired drying time is displayed.
Evacuation phase
Program Start-Stop
In the Evacuation Phase (fractionation) air is evacuated repeatedly until a
program-dependent pressure is reached. This occurs in alternation with
the inflow of steam up to a slight overpressure.
Depending on selected program and the current chamber temperature at
program start, additional
→ fractionations are connected.
Heating-up phase
The heating-up phase follows after the evacuation phase. The pressure
and the temperature climb with continual steam introduction in the
chamber until the sterilization parameters are reached.
Sterilization phase
After achieving the sterilization parameters of pressure and temperature,
the sterilization phase begins.
In alternation with pressure and temperature the remaining time of the
sterilization phase is also displayed.
A pressure discharge with a corresponding display is carried out at the
end of the sterilization phase.
Drying phase
The drying phase begins after the pressure discharge.
The chamber is ventilated with simultaneous pressure compensation at
the end of the drying cycle.
The regular drying time is 10 minutes for the Quick Program, and 15
minutes for the Universal Program and the Prion Program. The Gentle
Program requires 20 minutes for drying.
