Presto 16-Quart Pressure Canner and Cooker

Introduction and Overview

The Presto 16-Quart Pressure Canner and Cooker is designed for safe and confident home food preservation. This versatile appliance functions as both a pressure canner for low-acid foods such as vegetables, meats, and fish, and a boiling water canner for high-acid foods like fruits, jams, jellies, pickles, and salsas. Constructed from extra-strong, warp-resistant aluminum, it is suitable for use on regular and smooth-top ranges. This manual provides essential information for proper setup, operation, and maintenance to ensure safe and effective use of your pressure canner.

Important Safety Information

• Pressure Canning Method: Pressure canning is the only method recommended by the U.S.D.A. for safely preserving low-acid foods. Always follow tested recipes and guidelines for safe canning.
• Range Compatibility: This pressure canner is ideal for use on regular and smooth-top ranges. It is not designed for use on LP gas burners or gas ranges over 12,000 BTU.
• Lid Safety Features: The canner features an air vent/cover lock that allows pressure to build only when the cover is properly closed. The cover is also prevented from opening until the pressure inside is safely reduced.
• Read the Manual: Always read the complete canning instruction and recipe book included with your Presto Pressure Canner before initial use and for all canning procedures.

Setup

Before using your Presto 16-Quart Pressure Canner, ensure all components are present and properly assembled. Refer to the detailed instructions in the included manual for specific assembly steps.

1. Unpacking: Carefully remove all items from the packaging. Inspect for any damage.
2. Initial Cleaning: Wash the canner body, lid, and all accessories with warm, soapy water. Rinse thoroughly and dry.
3. Lid Assembly: Attach the pressure regulator weight to the lid according to the instructions. The lid features a pressure indicator and an overpressure release valve for safety.
4. Canning Rack: Place the canning/cooking rack at the bottom of the canner. This prevents jars from sitting directly on the canner's base.

Operating Instructions

Operating your pressure canner involves several critical steps to ensure food safety and proper preservation. Always consult the comprehensive instruction and recipe book for detailed guidance on specific recipes and processing times.

1. Prepare Jars and Food: Follow your chosen recipe for preparing food and sterilizing canning jars.
2. Load Canner: Place filled jars onto the canning rack inside the canner. Add the specified amount of water to the canner.
3. Secure Lid: Align the lid with the canner body and rotate it to lock it into place. Ensure the air vent/cover lock is properly engaged.
4. Heat and Vent: Place the canner on a heat source. Allow steam to escape steadily from the vent pipe for 10 minutes to ensure all air is removed.
5. Apply Pressure Regulator: Place the pressure regulator weight onto the vent pipe. The regulator will begin to rock or jiggle when the desired pressure is reached.
6. Process: Maintain the recommended pressure and processing time as specified by your recipe. Adjust heat as necessary to keep the regulator rocking gently.
7. Cool Down: After processing, turn off the heat and allow the canner to cool naturally until the pressure indicator drops completely. Do not force cool the canner.
8. Open Canner: Once the pressure indicator is down, remove the pressure regulator weight. Carefully open the lid by rotating it counter-clockwise and lifting it away from you to avoid steam burns.
9. Remove Jars: Use a jar lifter to remove hot jars and place them on a towel-lined surface to cool for 12-24 hours.

Maintenance

Regular maintenance ensures the longevity and safe operation of your Presto Pressure Canner.

• Cleaning: The canner body is dishwasher safe. Hand wash the lid, pressure regulator, and sealing ring with warm, soapy water. Rinse and dry thoroughly.
• Sealing Ring: Inspect the sealing ring for cracks or hardening before each use. Replace if necessary to ensure a proper seal.
• Vent Pipe: Ensure the vent pipe is clear of any food particles or debris. Use a small brush or pipe cleaner if needed.
• Storage: Store the canner with the lid inverted on the pot to allow air circulation and prevent odors. Keep the sealing ring separate or loosely placed to prolong its life.

Troubleshooting

If you encounter issues with your pressure canner, refer to the troubleshooting section in your included instruction manual. Common issues and their solutions are typically covered there. For example:

• Pressure Not Building: Check if the lid is properly sealed, the sealing ring is in good condition, and the vent pipe is clear.
• Steam Leaking: Ensure the lid is correctly aligned and locked, and the sealing ring is properly seated and not damaged.
• Food Not Processing Correctly: Verify that the correct pressure and processing time were maintained according to the recipe and altitude adjustments.
