Safety devices

  1. Breaker
    Protects your equipment from any possibility of failure in the power supply.
    Action: Interrupts the power supply.
  2. Thermal circuit breaker.
    Protection against short circuits and possible overheating in the primary network of the transformer.
    Action: Temporary interruption (until the temperature has dropped) in the winding.
  3. Safety valve.
    Protection against a possible increase in pressure within the chamber.
    Action: Escape steam until the restoration of a normal pressure level.
  4. Microswitch to control de state of the door.
    Exercises control in adjusting the door to start a sterilisation cycle.
    Action: Transmits signal to alert the incorrect position of the door.
  5. Thermostat for heating elements in the steam generator.
    Protection against possible overheating in the heating elements in the steam generator.
    Action: Interrupts the power supply to the heating elements in the steam generator.
  6. Thermostat for heating elements in the chamber.
    Protection against possible overheating in the heating elements in the chamber.
    Action: Interrupts the power supply to the heating elements in the chamber.
  7. Auto leveling hydraulic system.
    The hydraulic system returns to its natural if the sterilisation cycle is interrupted manually.
    Action: The internal pressure is restored automatically.
  8. Door lock.
    Effective to prevent accidental opening of the door protection.
    Action: Prevents door opening by a hydraulic locking system.

Optional accessories and replacements:

Autoclave – step by step:

1. Open the door, take the tools and accessories that are within the sterilization chamber, remove the wrapper and clean them.

2. Connect the power cord to a suitable power source.

3. Connect the printer.

4. Swith on: The main switch is located on the right bottom area in the front panel.

  • Once activated, the LCD screen is on, where basic operation icons such as the position of the door, the water level, the sterilisation programme, date, time, etc. appear.

5. Fill tank with distilled water.

  • Remove the top lid and fill, if you hear a signal, it means that you exceeded the permitted level of water in the tank, please stop immediately and drain the amount of water necessary for the signal off.

6. Preparation of material to be sterilised:

  • Place instruments that are of different materials in different trays, however, take care to separate them before sterilisation.
  • If the instruments are not stainless steel, put some sterilisation paper between the tray and the instruments.
  • Do not allow direct contact between instruments of different materials.
  • Verify that all instruments are in correct position.
  • Place instruments such as lenses, containers, tubes, etc. inverted, so that water does not stagnate within them.
  • Do not overload the trays above their limit.
  • Do not overlap the trays on top of each other, or put them in direct contact with the wall of the sterilisation chamber.
  • Do not use metal clips or pins, this may impair the operation of the steriliser.

7. Select the sterilisation programme.

8. Start the sterilisation cycle.

  • After selecting the sterilisation programme, insert instruments into the chamber on the trays, using the supplied plastic handle.
  • Once the instruments are within the chamber, close the door.
  • Caution: Be sure to close the door, otherwise the steriliser displays an alarm and can not start or stops the programme during the cycle.

9. Start the sterilisation programme.

  • Press the start button, then the steriliser starts operating during approximately between 30-75 minutes.

10. After the sterilisation cycle.

  • After completion of the sterilisation cycle, the printer will print the full report automatically.
  • After the pressure drops to zero, you can open the door and remove the instruments. The steriliser alerts by a beep once the sterilisation cycle is completed.
  • Caution: Whenever you remove instruments, use the supplied plastic handle for supporting trays.

IMPORTANT: Do not reuse wastewater.


  • There must be at least 10 cm of free space around the steriliser, 25 cm at the top, and enough room to open the door.
  • The place where the steriliser is used must have adequate ventilation.
  • The steriliser must be placed on a stable surface and at an adequate height for handling.
  • Do not cover or block the lateral outlets or outlet grille air condenser fan.
  • Do not place the steriliser near water sources where it can be splashed.
  • Keep away from heat sources.
