Setup and First Use
Before using your pressure cooker for the first time, follow these steps:

- Initial Cleaning: Wash the pressure cooker pot, lid, and pressure regulator with warm, soapy water. Rinse thoroughly and dry completely. Ensure all parts are clean and free of debris.
- Lid Placement: Place the lid onto the pot, aligning the lid's arrow with the handle's arrow. Rotate the lid clockwise until it locks securely into place.
- Pressure Regulator: Place the pressure regulator onto the steam vent pipe on the lid. Ensure it sits firmly.

Operating Instructions
Follow these steps for safe and effective pressure cooking:
- Add Ingredients: Place your food and the required amount of liquid into the pressure cooker pot. Do not fill the cooker more than two-thirds full for most foods, and no more than half full for foods that expand, such as beans or grains. Always ensure there is at least 1 cup of liquid.
- Secure the Lid: Place the lid on the pot and rotate it clockwise until it is securely locked. Ensure the handles are aligned.
- Place Regulator: Position the pressure regulator firmly on the steam vent pipe.
- Heat Source: Place the pressure cooker on a gas stovetop burner. Use a burner size appropriate for the base of the cooker to ensure even heating.
- Build Pressure: Turn the heat to high. Steam will begin to escape from the vent pipe before the regulator starts to jiggle. Once the regulator begins to jiggle steadily, indicating full pressure, reduce the heat to maintain a gentle, consistent jiggling.
- Cooking Time: Begin timing your recipe from when the regulator starts to jiggle consistently.
- Release Pressure: Once cooking is complete, remove the cooker from the heat. There are two methods for pressure release:
- Natural Release: Allow the cooker to cool down naturally. The pressure will gradually decrease, and the safety valve will drop. This method is ideal for foods that benefit from continued cooking, like meats.
- Quick Release: Carefully move the cooker to the sink and run cold water over the lid (avoiding the regulator and safety valve) until the safety valve drops. This method is suitable for delicate foods like vegetables.
- Open the Cooker: Once the safety valve has dropped and no steam is escaping, carefully rotate the lid counter-clockwise to unlock and remove it. Always open the lid away from your face to avoid residual steam.
