- Select Temperature: Use the temperature selection button to choose between 121°C (30 minutes) or 134°C (10 minutes). The indicator light next to the selected temperature will light up. For most applications, 134°C is faster and equally effective.
- Start Cycle: Press the start button to begin the sterilization cycle. The display will show the current temperature and pressure.
- Monitor Cycle: The autoclave will heat up, build pressure, and maintain the selected temperature for the specified duration. Monitor the pressure gauge to ensure it operates within safe limits.
- End of Cycle: Once the sterilization time is complete, the unit will beep and display 'End'.
- Pressure Release: Before opening the door, ensure the pressure gauge reads zero. Open the drain valve to release any remaining pressure and steam.
- Cooling: Slightly open the door to allow natural cooling and air drying of the instruments. This unit does not have an active drying cycle.
- Remove Instruments: Once cooled, use the tray handle to carefully remove the sterilized instruments.
