AUTOCLAVE – step by step:

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

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

3- 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.

4- 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.

5- 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.

6- Choose the sterilisation programme.

7- Start the sterilisation cycle.

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

8- Start the sterilisation programme.

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

9- Sterilisation cycle finished.

  • After finishing the sterilisation cycle, the printer (not included*) 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 used water.


  • 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 appropriate ventilation.
  • The steriliser must be placed on a stable surface and at an appropriate height for handling.
  • Do not cover or block the lateral outlets or the outlet air grid of the condenser ventilator.
  • Do not place the steriliser near water sources where it can be splashed.
  • Keep away from heat sources.
