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:
When starting the program, simultaneously press the K
EY
(S)
AND
K
EY
(+).
The display shows
Additional drying selected
. Then the program
sequence begins.
Starting the program
If you selected a program with the program selection button (P), in addition
to the selected program, the sterilization temperature is displayed and
whether the respective program is suitable for wrapped or unwrapped
sterilizing materials.
Press the K
EY
(S), in order to start the program.
The steam sterilizer checks the transport of the
→
feed water and its
→
conductivity.
If the Quick-Program S is started, the warning text
Warning only
unwrapped instruments
is shown on the display.
If the load exclusively contains unwrapped instruments, press the K
EY
(S) once again to confirm and start the program.
Program run
After starting the program, you can follow the program run in the
→
display.
Chamber temperature and pressure as well as the remaining duration until
end of sterilization respectively the expired drying time is displayed.
Evacuation phase
In the evacuation phase the
→
fractionated flow method with pulsating,
repeated steam entry and discharge, sucks the air out of the chamber and
introduces saturated steam into the chamber.
Depending on selected program and the current chamber temperature at
program start, additional
→
fractionations follow.
Heating-up phase
The heating-up phase follows after the evacuation phase. A pressure
discharge with a corresponding display is carried out at the end of the
sterilization phase.
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 regular drying time is approx. 1 minute for the Quick-Program S and
approx. 10 minutes for all other programs.
