5. Operating Instructions
Follow these steps for a typical sterilization cycle.
- Power On: Flip the main power switch to the ON position. The digital display will illuminate.
- Load Items: Place the instruments or materials to be sterilized onto the trays. Ensure items are arranged to allow proper steam circulation. Do not overload the chamber.
- Close Door: Close the autoclave door and rotate the handle clockwise until it is securely locked. Ensure the door is fully sealed to prevent steam leakage.
- Select Program: Use the program selection buttons on the control panel to choose the desired sterilization cycle (e.g., 121°C for unwrapped, 134°C for wrapped). The display will show the selected temperature and time.
- Start Cycle: Press the START/STOP button to begin the sterilization cycle. The "READY" indicator light will typically illuminate when the unit is ready to start or during the cycle.
- Monitoring: Monitor the pressure and temperature displays during the cycle. The autoclave will automatically proceed through the sterilization phases (heating, sterilization, drying).
- Cycle Completion: Once the cycle is complete, an audible alarm may sound, and an indicator light will signal completion. Allow the pressure to fully release before attempting to open the door.
- Unload Items: Carefully rotate the door handle counter-clockwise to open the door. Use the provided plastic handle to remove the hot trays and sterilized items. Allow items to cool before handling.
