SAFETY FEATURES
The sterilizer features several devices that assure the full safety for the operators.
Door with dual lock control
An electromechanical device allows the door to be opened only if the following conditions are met:
-
unit power supplied and turned on
-
no current alarms
-
internal pressure not dangerous for the operator
For further safety, to unblock the door at the end of cycle or in case of alarm it is necessary to press the
Start/Stop button.
Attention: If the equipment is turned off with the door open, do not apply force on
the handle to try closing the door. To close it, the equipment must be on.
Protection against overpressure
– safety and decompression valves
Safety valve - it takes over when the pressure inside the chamber exceeds the value of 2,55 bar. To
verify the efficiency of the valve, when the unit is cold and switched off, unscrew the black cap of the
valve, when a “click” is heard pull it gently : you have to feel that the cap is free to move. The valve can
not be adjusted or serviced for safety reasons. Follow the maintenance program described in the ap-
pendix SERVICE BOOK to assure the safety of the unit.
Decompression valve
– it takes over when the pressure inside the chamber exceed the value of 2,4 bar;
an acoustic signal warns the operator and the display shows the message ALARM 10.
Overheating protection
The temperature inside the chamber is programmed so as not to exceed the limit of 142 °C; in case of fault,
a further protection takes over to prevent the temperature from rising over 150 °C.
Blackout protection
In case of power blackout during the sterilization cycle, the pressure inside the chamber is completely re-
leased to the drain valve. On power supply restore, the display will show the message BLACK OUT.
Automatic switch off
Elapsed 30 minutes from the end of the cycle without opening the door or activating a front panel button, the
unit will automatically switch off.
This function is not operating if no sterilization cycle has been carried out and completed
.
