8 Transportation and storage
Switch off the sterilizer before transportation or storage.
Pull out the plug. Let the machine cool down.
Drain the distilled water tank and the used water tank.
Conditions for transport and storage
Temperature: -20°C ~ +50°C
Relative humidity: ≤ 85%
Atmospheric pressure: 50kPa~ 106kPa.
9 Safety devices
1. Main breaker: Protection of the instrument against possible failures of the heating resistor.
Action: Interruption of the electric power supply.
2.Thermal cutouts on the main transformer winding: protection against possible short circuit and
main transformer primary winding overheating
Action: Temporary interruption of winding.
3.Safety valve: Protection against possible sterilization chamber over-pressure.
Action: Release of the steam and restoration of the safety pressure.
4.Safety micro-switch for the door status: Comparison for the correct closing position of the door.
Action: Signal of the wrong position of the door
5.Thermostat on chamber heating resistors: Protection for possible overheating of the chamber
heating resistors.
Action: Interruption of the power supply of the chamber resistors.
6.Thermostat on steam generator heating resistors: Protection for possible overheating of the
steam generator heating resistors.
Action: Interruption of the power supply of the steam generator resistors.
7.Door safety lock: Protection against accidental opening of the door.
Action: Impediment of the accidental opening if the door during the program.
8.Self-leveling hydraulic system: Hydraulic system for the natural pressure leveling in case of
manual cycle interruption, alarm or blackout.
Action: Automatic restoration of the atmospheric pressure inside the chamber.
