SAFETY INFORMATION - 2
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
For additional safety, the Start/Stop button must be pressed to unlock the door at the end of a cycle.
CAUTION
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 relief valve
Safety valve
This is a valve located on the back of the device that is triggered when the pressure inside the
chamber exceeds 2.55 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 relief valve
This is triggered when the pressure inside the sterilization chamber exceeds 2.4 bar; an acoustic
signal alerts the operator and the message ALARM 16 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 BLACK OUT 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.
NOTE This function is not implemented if no sterilization cycle has been run.
