Setup
- Unpacking: Carefully remove all components from the packaging. Retain packaging for future storage or transport if needed.
- Initial Cleaning: Before first use, wash the pot body, lid, and sealing ring with warm, soapy water. Rinse thoroughly and dry completely.
- Inspect Components: Ensure the sealing ring is properly seated in the lid and that all valves (self-locking, limit, safety) are clear and free from obstructions.
- Lid Assembly: Place the lid onto the pot, aligning the arrows or indicators on the lid and pot handles. Rotate the lid clockwise until it locks securely.
Operating Instructions
This pressure cooker is compatible with gas stoves and electric cooktops.

This image demonstrates the pressure cooker's compatibility with various stove types, including induction, gas, electric, and ceramic, highlighting its versatile thermal conduction design.
- Add Ingredients: Place your food and the required amount of liquid into the pressure cooker. Do not fill more than two-thirds full for most foods, and no more than half full for foods that expand (e.g., beans, grains).
- Secure the Lid: Place the lid on the pot, ensuring it is properly aligned and locked. The self-locking valve will engage.
- Heat Application: Place the pressure cooker on your stove over medium-high heat.
- Building Pressure: As steam builds, the pressure indicator will rise. Once full pressure is reached, the limit valve will begin to release steam with a steady hiss. Reduce heat to maintain a steady, gentle release of steam.
- Cooking Time: Begin timing your recipe once full pressure is achieved.
- Releasing Pressure:
- Natural Release: Remove the cooker from heat and allow pressure to drop naturally. This is suitable for foods that benefit from continued cooking.
- Quick Release: For foods that require precise cooking times, carefully move the pressure cooker to the sink and run cold water over the lid (avoiding the valves) until pressure drops. Alternatively, for models with a quick release button/valve, activate it carefully.
- Opening the Lid: Once the pressure indicator has fully dropped and no steam is escaping, carefully open the lid by rotating it counter-clockwise and lifting it away from you to avoid residual steam.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pressure not building or steam escaping from lid edge. | Lid not properly sealed, sealing ring damaged or improperly seated, insufficient liquid. | Ensure lid is securely locked. Check sealing ring for proper placement and damage; replace if necessary. Add more liquid. |
| Food burning on the bottom. | Too little liquid, heat too high. | Always use sufficient liquid. Reduce heat once pressure is reached. |
| Valves appear stuck or not functioning. | Food debris, mineral buildup. | Clean valves thoroughly after each use. Ensure no food particles are blocking the mechanism. If a valve component appears loose or detached, do not use the cooker and contact customer support. |
| Lid difficult to open after cooking. | Residual pressure inside. | Ensure all pressure has been released and the pressure indicator has dropped completely before attempting to open. Never force the lid open. |
