Safety Information
Always read and understand all instructions before using your pressure cooker. Failure to follow safety guidelines can result in serious injury or property damage.
- Cover Lock Indicator: This feature visually indicates when pressure is present inside the cooker and prevents the cover from being removed until the pressure is safely reduced. Do not attempt to force the lid open if the indicator is up.
- Overpressure Plug: An overpressure plug is designed to release steam if excessive pressure builds up, acting as a safety mechanism. Ensure it is clean and free from obstruction before each use.
- Liquid Requirements: Always add the minimum required liquid as specified in recipes to generate steam and pressure.
- Heat Source: This pressure cooker is suitable for use on electric, smooth-top, and gas ranges.
Setup
Before first use, and after each subsequent use, ensure all parts are clean and properly assembled.
- Unpacking: Carefully remove all components from the packaging. Check for the pressure cooker pot, lid, sealing ring, overpressure plug, air vent/cover lock, and cooking rack.
- Initial Cleaning: Wash all parts in warm, soapy water. Rinse thoroughly and dry completely.
- Lid Assembly: Ensure the sealing ring is properly seated inside the rim of the lid. Verify that the air vent/cover lock and overpressure plug are securely in place and clear of any food debris.
- Cooking Rack: The included cooking rack can be placed at the bottom of the cooker to elevate food, allowing for steaming or cooking multiple items without intermingling flavors.

Operating Instructions
Follow these steps for safe and effective pressure cooking:
- Add Ingredients: Place food and the required amount of liquid into the pressure cooker. Do not overfill; typically, the cooker should not be more than two-thirds full for most foods, and half full for foods that expand, such as beans or grains.
- Secure the Lid: Place the lid on the pot, aligning the handles. Rotate the lid clockwise until the handles are aligned and the lid is securely locked. The cover lock indicator should be in the down position.
- Heat Application: Place the cooker on a burner over high heat. The air vent/cover lock will rise, indicating pressure is building. Once the pressure regulator begins to rock gently, reduce the heat to maintain a slow, steady rocking motion.
- Cooking Time: Begin timing your recipe once the pressure regulator starts rocking.
- Pressure Release: Once cooking is complete, remove the cooker from heat. Allow pressure to reduce naturally, or use the quick cold water release method by running cold water over the rim of the lid (avoiding the pressure regulator) until the cover lock indicator drops.
- Open the Cooker: Once the cover lock indicator has dropped completely, indicating no pressure inside, twist the lid counter-clockwise to open. Always open the lid away from your face to avoid steam burns.

Maintenance and Cleaning
Proper maintenance ensures the longevity and safe operation of your pressure cooker.
- Dishwasher Safe: The pressure cooker is fully immersible and dishwasher safe for easy cleaning.
- Sealing Ring: Remove the sealing ring from the lid after each use and wash it thoroughly. Ensure it is clean and flexible before reinserting.
- Vent Pipe and Overpressure Plug: Regularly clean the vent pipe with a small brush or pipe cleaner to prevent blockages. The overpressure plug is also removable for cleaning.
- Aluminum Body: Use non-abrasive cleansers to clean the polished aluminum body. Occasional use of a fine metal polish can help maintain its shine.
