Safety information
2.2 Safety and protection features on the device
The sterilizer has several devices, listed below, that ensure the total safety of operators.
2.2.1 Soft-close door with double safety
An electromechanical device allows the door to be opened only under the following conditions:
• device plugged in and switched on
• no alarms activated
• internal pressure not hazardous to the operator (Ambient pressure ±15mbar)
For additional safety, the Unlock button on display must be pressed to unlock the door at the end of a cycle.
If the device is switched off with the door open, do not try to close the door by forcing the handle. To
close the door, simply turn the device on again using the main switch.
2.2.2 Overpressure protection - safety valve and pressure sensor
Safety valve
This is a valve located on the back of the device that is triggered when the
pressure inside the chamber exceeds 2.6 bar. To check that valve is working
properly, switch the device off and allow it to cool down, then unscrew the black
cap, pull it slightly until a “click” is heard and then check that it moves freely. The
safety valve requires no adjustment or maintenance.
Pressure sensor
This is triggered when the pressure inside the sterilization chamber exceeds 2.4
bar; an acoustic signal alerts the operator and the message A75 appears on the
display.
2.2.3 Blackout protection
In the event of a power supply failure during the sterilization cycle, the pressure in the chamber is completely
released and brought down to ambience level. When the power supply returns, the message A70 appears on the
display.
2.2.4 Overheating Protection
The temperature inside the sterilization chamber is programmed to not exceed a limit of 142 °C; in the event of
failure, additional protection is provided to prevent the temperature from rising above 150 °C.
2.2.5 Automatic power off
Thirty minutes after the end of the cycle, unless the door has been opened or a button pressed on the front panel,
the device automatically switches off.
This function is not implemented if no sterilization cycle has been run.
