3. Safety Information
Your safety is paramount. This pressure cooker incorporates an advanced 4-layer safety system to ensure secure operation. Always adhere to the following safety guidelines:
- Easy Lock Lid: Ensures the lid is securely fastened before pressure builds.
- Safety Valve: Releases excess pressure if it exceeds safe levels.
- Secure Lid Window: Provides an additional visual indicator and safety mechanism.
- Pressure Release Valve: Allows for controlled release of pressure.
- Never force the lid open while the cooker is pressurized.
- Do not fill the cooker more than two-thirds full (2/3) for most foods, and no more than half full (1/2) for foods that expand, such as rice or dried beans.
- Always ensure all valves are clean and free from obstructions before each use.
- Keep hands and face away from the steam vent when releasing pressure.

4. Setup
Initial Cleaning:
- Before first use, wash the pressure cooker pot, pressure lid, and glass lid thoroughly with warm, soapy water.
- Rinse all components completely and dry them.
- Inspect the silicone gasket and all valves on the pressure lid to ensure they are properly seated and free from any debris.
Component Check:
- Ensure the pressure regulator valve is correctly installed on the lid.
- Verify that the safety valve and secure lid window are clear and functional.
5. Operating Instructions
Using as a Pressure Cooker:
- Add Ingredients: Place your food and liquid into the pressure cooker pot. Observe the maximum fill lines (2/3 full for most foods, 1/2 full for expanding foods).
- Secure the Lid: Place the pressure lid onto the pot. Align the lid according to the markings and engage the easy-lock system by rotating the handle until it clicks into place. Ensure it is fully sealed.
- Apply Heat: Place the cooker on a suitable stovetop (induction, gas, electric, halogen, or vitro-ceramic). Set the heat to high.
- Build Pressure: As steam builds, the pressure indicator will rise. Once full pressure is reached, the pressure regulator valve will begin to release steam steadily. Reduce the heat to maintain a consistent, gentle steam release.
- Cook: Cook for the recommended time according to your recipe.
- Release Pressure: Once cooking is complete, remove the cooker from heat. There are two methods for pressure release:
- Natural Release: Allow the pressure to dissipate naturally. This is suitable for foods that benefit from additional cooking time. The pressure indicator will drop on its own.
- Quick Release: Carefully turn the pressure release valve to vent steam. Use caution as hot steam will escape. Once the pressure indicator drops, the lid can be opened.
- Open the Lid: Once all pressure has been released and the indicator has dropped, unlock and remove the lid. Always open the lid away from your face.

Using as a Traditional Pot:
To use the cooker as a regular pot, simply place your ingredients inside and cover with the provided tempered glass lid. The glass lid includes a steam vent for conventional cooking.
6. Cleaning and Maintenance
Proper cleaning and maintenance will extend the life of your pressure cooker.
- Pot Cleaning: The stainless steel pot is dishwasher safe. For hand washing, use warm, soapy water and a non-abrasive sponge.
- Lid Cleaning: The pressure lid should be hand washed. Remove the silicone gasket and wash it separately. Clean all valves and openings to ensure they are free from food particles.
- Glass Lid Cleaning: The glass lid is dishwasher safe. For hand washing, use warm, soapy water.
- Drying: Ensure all parts are completely dry before reassembling and storing.
- Gasket Maintenance: Periodically check the silicone gasket for cracks or damage. Replace if necessary to maintain a proper seal.
7. Troubleshooting
If you encounter issues with your pressure cooker, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pressure not building | Lid not sealed properly; insufficient liquid; gasket damaged; valve obstructed. | Ensure lid is locked correctly; add more liquid; inspect/replace gasket; clean valves. |
| Steam leaking from lid edge | Lid not sealed; gasket improperly seated or damaged; food debris on rim. | Re-seat lid; check/clean/replace gasket; clean pot rim. |
| Lid stuck after cooking | Pressure not fully released. | Ensure pressure indicator has dropped completely before attempting to open. If necessary, cool under cold water (avoiding valves) to accelerate pressure drop. |
| Food burning at bottom | Insufficient liquid; heat too high. | Always use adequate liquid; reduce heat once pressure is reached. |
