Setup

1. Unpacking: Carefully remove all components from the packaging. Retain packaging for future storage or transport.
2. Initial Cleaning: Before first use, wash the pressure cooker body, lid, gasket, and racks with warm, soapy water. Rinse thoroughly and dry completely.
3. Gasket Installation: Ensure the rubber gasket is properly seated in the lid's groove. A correctly installed gasket is crucial for maintaining pressure.
4. Pressure Regulator: Select the appropriate pressure regulator (5, 10, or 15 PSI) based on your recipe and altitude. Place it securely on the vent pipe.
5. Placement: Place the pressure cooker on a stable, level cooking surface. It is compatible with most cooking surfaces, including glass stovetops.

Operating Instructions

General Pressure Cooking

1. Add Ingredients: Place food and the required amount of liquid into the pressure cooker. Do not exceed the maximum fill line.
2. Secure Lid: Place the lid on the cooker, aligning the arrows or indicators, and rotate until it locks securely. Ensure the handles are properly engaged.
3. Heat Application: Place the cooker on a high heat setting. Steam will begin to escape from the vent pipe.
4. Pressure Build-up: Once a steady stream of steam is released, place the selected pressure regulator weight onto the vent pipe. The pressure indicator will rise, and the regulator will begin to jiggle or rock, indicating that the desired pressure has been reached.
5. Cooking Time: Reduce heat to the lowest setting that maintains a steady jiggle or rocking motion of the pressure regulator. Begin timing according to your recipe.
6. Pressure Release: After cooking, turn off the heat. Allow pressure to release naturally (NPR) or use the quick release method if specified by the recipe. Never remove the pressure regulator or open the lid until the pressure indicator has fully dropped.

Pressure Canning

This pressure cooker doubles as a canner, ideal for low-acid foods. Always refer to tested canning recipes and guidelines from reputable sources (e.g., USDA Extension). Ensure jars are clean and free from defects.

1. Prepare Jars: Fill jars with prepared food, leaving appropriate headspace. Wipe rims clean and apply lids and bands.
2. Load Canner: Place the canning rack(s) at the bottom of the cooker. Arrange jars on the rack, ensuring they do not touch each other or the sides of the cooker.
3. Add Water: Add 2-3 inches of hot water to the canner, or as specified by your canning recipe. Do not pour water directly onto jars.
4. Process: Follow the general pressure cooking steps above, using the pressure and processing times specified in your canning recipe for your altitude.
5. Cool Down: After processing, turn off heat and allow pressure to drop naturally. Do NOT quick release pressure when canning, as this can cause liquid loss from jars. Once pressure is fully released, carefully remove the lid.
6. Remove Jars: Using a jar lifter, carefully remove hot jars and place them on a towel-lined surface, leaving space between them to cool for 12-24 hours.

Maintenance and Cleaning

• Daily Cleaning: After each use, wash the cooker body and lid with warm, soapy water. Rinse thoroughly and dry immediately to prevent water spots and corrosion.
• Gasket Care: Remove the rubber gasket from the lid after each use for thorough cleaning. Inspect it for cracks, tears, or stiffness. Replace if damaged. Store the gasket loosely or inverted to prevent flattening.
• Vent Pipe and Pressure Regulator: Clean the vent pipe and pressure regulator regularly to ensure they are free from food particles or blockages. Use a small brush or pipe cleaner if necessary.
• Dishwasher Safety: The pressure cooker is dishwasher safe, but hand washing is recommended to preserve the finish and extend the lifespan of components, especially the gasket.
• Storage: Store the pressure cooker with the lid inverted on the pot to allow air circulation and prevent odors or moisture buildup.
