4.2.2 Starting a sterilization cycle
Press the key START/STOP to start the selected cycle.
The door is locked and stays locked throughout the cycle duration.
The parameters of the selected cycle are shown once again for 10 seconds, then the sterilizer starts and
runs the cycle phases automatically. The various steps of the cycle are microprocessor controlled and se-
quentially shown on the display; in this way the operator can monitor the progress of the sterilization
phases and the times. The signalling for the various phases of the cycle are reported on the following:
Led heating turns on
Display Time starts to record the cycle duration
Display Pressure shows the chamber pressure value
Display Temperature shows the chamber temperature value
he program indication Led (1, 2, 3 o 4) starts to flash.
Heating (water entry and heating)
During this first phase a water dose is entered into the chamber and the microprocessor enables
the heating phase. Pump operation may be slightly noisy.
Sterilize
Reached the pre-set parameter values, Led HEATING turns off, and Led STERILIZE turns on. The
display Time starts the countdown marking the time remaining to the end of the sterilization proc-
ess, and the Pressure and Temperature displays show the pressure and temperature values of the
steam.
The sterilization phase is followed by the decompression phase, with the display Pressure showing
the decreasing pressure values down to 0. Again, the display Time will start the countdown of the
decompression phase. Based on the our experiences, the decompression time has been slightly
extended in order to minimize the thermal shock consequent to the status change of the steam.
Dry
Over the decompression phase, Led STERILIZE starts to flash to signal the completion of the ster-
ilization process. At the same time the Led DRY turns on, signalling the start of the drying phase.
Throughout this phase, the chamber heaters keep the chamber warm according to a microproces-
sor-controlled logic. The display TIME shows the countdown of this phase. Follows the forced venti-
lation phase through the bacterial filter, the display Time shows also the countdown of this phase.
End of cycle
As soon as the drying is over, Led DRY turns off and Led READY and STERILIZE turn on. A 10-
second alert signal is generated to draw the attention by the operator. The chamber heaters are set
at reduced power (pre-heating) until the door is open. The TIME display shows the total time of the
cycle, the displays TEMP. and PRESS show respectively the current temperature and pressure of
the chamber.
At the end of the special cycle only Led READY will light (not Led STERILIZE) to signal that the
efficiency of the cycle has not been tested by the manufacturer.
To unlock the door before opening it, press the key
Start/Stop
.
The cycle is over and the load can be taken out.
