Assembling the Pressure Cooker

- Insert the sealing ring into the lid, ensuring it is seated correctly in the groove.
- Close the lid by aligning the arrows and turning it clockwise until it clicks into place.
- Set the steam release handle to the ‘Sealing’ position for pressure cooking.
Initial Testing and First Use
Before cooking your first meal, it’s recommended to run a quick water test to familiarize yourself with the functions and ensure everything operates smoothly.
- Add 1-2 cups of water into the inner pot.
- Close the lid, set the steam release handle to ‘Sealing.’
- Select the ‘Pressure Cook’ function and set the timer for 5 minutes.
- Once the cycle completes, allow natural pressure release for 10 minutes, then turn the steam release handle to ‘Venting’ to release remaining pressure.
Safety Tips and Troubleshooting
- Always check that the sealing ring is properly installed and undamaged before each use.
- Ensure the lid is securely closed and the steam release handle is in the correct position.
- If the device isn’t sealing properly, inspect the sealing ring for cracks or debris and clean or replace as needed.
- Do not overfill the inner pot; keep within the maximum fill line for safety and optimal results.
Maintenance and Care
Regularly clean the lid, sealing ring, and inner pot after each use. Replace the sealing ring every 12-18 months or when it shows signs of wear for safety and proper sealing.
