Introduction
This manual provides essential instructions for the safe and efficient use of your Lagostina 010001010405 Pressure Cooker. Please read all instructions carefully before first use and retain this manual for future reference.
The Lagostina pressure cooker is designed for fast and even cooking, featuring a Lagofusion bottom for optimal heat distribution and advanced safety mechanisms.
Safety Information
Always follow basic safety precautions when using a pressure cooker to reduce the risk of injury or damage.
- Read all instructions before use.
- Do not fill the pressure cooker more than two-thirds full. For foods that expand (e.g., rice, dried vegetables), do not fill more than half full.
- Ensure the lid is properly closed and locked before heating.
- Never force the lid open. Ensure all internal pressure has been released before attempting to open.
- Do not use the pressure cooker in an oven.
- Keep children away from the pressure cooker during use.
- Regularly inspect the operating valve, safety valve, and gasket for blockages or wear.

- Pot: The main cooking vessel, made of stainless steel with a Lagofusion bottom for even heat distribution.
- Lid: Features the operating valve, safety valve, and Leverblock mechanism.
- Main Handle: For securing and opening the lid.
- Side Handles: For safe lifting and carrying.
- Operating Valve: Releases steam gradually once cooking pressure is reached.
- Leverblock: A safety feature that prevents the lid from being opened until all pressure is released.
- Safety Valve: An additional safety mechanism that releases excess steam if the operating valve becomes blocked.
- Gasket: Creates a seal between the pot and the lid.

Setup
- Unpacking: Carefully remove all packaging materials. Retain packaging for potential future transport or storage.
- Initial Cleaning: Before first use, wash the pot, lid, and all accessories (basket, ecodose) with warm soapy water. Rinse thoroughly and dry completely.
- Gasket Installation: Ensure the rubber gasket is correctly seated inside the lid rim. It should fit snugly and evenly.
- Familiarization: Practice opening and closing the lid without food or water to understand the locking mechanism.
Operating Instructions
1. Filling the Pressure Cooker
- Add food and the required amount of liquid to the pot. Always use at least 1 cup (250ml) of liquid to generate steam.
- Do not exceed the maximum fill line (typically two-thirds full). For foods that expand, do not exceed the half-full line.
- If using the basket for steaming, place it on the trivet (if included) or directly into the pot with water below the basket level.
2. Closing the Lid
- Align the lid with the pot.
- Lower the lid onto the pot.
- Rotate the main handle until it locks securely into place. The Leverblock mechanism will engage, preventing accidental opening.
3. Heating and Pressure Building
- Place the pressure cooker on a suitable heat source (gas, electric, induction).
- Heat on high until steam begins to escape steadily from the operating valve. This indicates that full pressure has been reached.
- Once steam is steadily escaping, reduce the heat to maintain a gentle, consistent steam release. This is the start of your cooking time.
4. Releasing Pressure
There are generally two methods for releasing pressure:
- Natural Release: Remove the pressure cooker from the heat source and allow it to cool down naturally. Pressure will gradually decrease, and the operating valve will drop. This method is ideal for foods that benefit from continued cooking, such as stews and roasts.
- Quick Release (under cold water): For faster pressure release, carefully place the pressure cooker under a cold water tap, allowing water to run over the lid (avoiding the operating valve) until the operating valve drops. This method is suitable for delicate foods like vegetables. Caution: Do not immerse the entire cooker in water.
5. Opening the Lid
- Ensure all pressure has been released and the operating valve has dropped. The Leverblock mechanism will disengage.
- Rotate the main handle to unlock the lid.
- Carefully lift the lid away from you to avoid steam burns.
Maintenance and Cleaning
- Daily Cleaning: After each use, wash the pot, lid, and gasket with warm soapy water. Rinse thoroughly. The pot and lid are dishwasher safe.
- Gasket Care: Remove the gasket from the lid for cleaning. Inspect it for cracks or damage. Replace the gasket annually or if signs of wear are visible.
- Valve Cleaning: Ensure the operating valve and safety valve are clear of food particles. Refer to the manufacturer's instructions for specific valve disassembly and cleaning if necessary.
- Storage: Store the pressure cooker with the lid inverted on the pot to allow air circulation and prevent the gasket from compressing permanently.
