The model specifications are listed in the pressure-cooking chart section of the owner’s manual.

Important Safety Instructions

The Power Pressure Cooker XL cooks food under pressure and produces very hot steam. Incorrect operation can cause burns, scalding or other injury.

General safety precautions

• Read the operating instructions before using or cleaning the cooker.
• Do not allow children to operate the appliance.
• Do not touch hot surfaces; use the handles or knobs.
• Do not immerse the cord, plug, housing or cooker base in water.
• Unplug the unit when it is not being used and before cleaning.
• Allow the cooker to cool before removing or installing parts.
• Do not operate it with a damaged cord or plug.
• Do not use accessories or utensils that are not recommended by the manufacturer.
• Do not use the cooker outdoors.
• Keep the electrical cord away from hot surfaces and countertop edges.
• Do not place the cooker on or near a hot burner or inside a heated oven.
• Take extra care when moving the cooker while it contains hot liquids.
• Use the appliance only for its intended purpose.

Do not overfill the inner pot

Never fill the removable inner pot above its MAX line.

For foods that expand during cooking, including rice and dried beans, the manual recommends following the applicable pressure-cooking recipe and, as a general rule, keeping the contents below approximately the halfway point.

Overfilling can obstruct the pressure-release system and allow excessive pressure to develop.

Foods that can foam or clog the steam vent

Extra care is required with foods that may foam, froth or sputter, including:

• Applesauce
• Cranberries
• Pearl barley
• Oatmeal and other cereals
• Split peas
• Noodles
• Macaroni
• Rhubarb
• Spaghetti

Recipes involving these foods should be followed carefully because food particles or foam can interfere with the pressure-release system.

Never force the lid open

The lid must not be forced open while pressure remains inside the cooker.

If the cooker is difficult to open, it may still be pressurized.

To release pressure:

1. Press KEEP WARM/CANCEL.
2. Use tongs or another kitchen tool to carefully move the Pressure Valve to the OPEN position.
3. Allow all steam and pressure to escape.
4. Turn the lid handle clockwise only after pressure has been released.
5. Open the lid away from the body and face.

Never use a bare hand to move the hot pressure valve after cooking.

Electrical requirements

The cooker is designed for a 3-prong grounded 120V electrical outlet.

The owner’s manual instructs users to:

• Plug it directly into a wall outlet.
• Avoid extension cords.
• Use a properly grounded outlet.
• Prefer a dedicated electrical circuit so other appliances do not overload the circuit.

Built-In Safety Features

The PPC770 includes several mechanical and electronic safety systems.

The manual explains these six systems as built-in protections against abnormal pressure or temperature conditions.

Power Pressure Cooker XL Program Settings

These program values come from the PPC770 program-settings chart.

Keep Warm Mode

After a pressure-cooking cycle finishes, the cooker automatically switches to KEEP WARM.

The mode is designed to hold cooked food at serving temperature for an extended period.

The manufacturer notes that food kept in Keep Warm for more than four hours may begin losing desirable flavor and texture.

Steam Mode

The Steam program quickly heats liquid inside the inner pot to boiling.

It can be used for steaming and cooking foods suited to the steaming process.

How to Release Pressure

The Pressure Valve is used to release internal pressure quickly.

To vent the cooker:

1. Finish or cancel the cooking program.
2. Keep hands and skin away from the steam outlet.
3. Use tongs or another suitable kitchen tool.
4. Carefully rotate the Pressure Valve to the OPEN / Vent position.
5. Wait until steam has completely stopped.
6. Make sure all internal pressure has been released.
7. Open the lid away from the body.

Never move the hot pressure valve with bare hands.

What to Do if Steam Comes Out Around the Lid

Steam escaping from the sides of the lid while the Pressure Valve is in the Lock position generally indicates that the lid has not seated correctly.

The manual recommends checking the following:

1. Make sure the rubber gasket is installed.
2. Gently press down on the lid to help it seal.
3. Check the Float Valve.
4. Make sure the Float Valve can move freely up and down.
5. Confirm that its silicone gasket is correctly fitted.

An incorrectly assembled Float Valve can allow steam to escape or prevent the cooker from building pressure.

Condensation collecting in the condensation collector is considered normal.

Pressure Cooking Times

All pressure-cooking modes require liquid, such as water or stock.

Never fill the inner pot above the MAX line.

Pressure Canning Guide

The PPC770 manual includes a dedicated pressure-canning section.

The manufacturer warns that canning is not an area for experimentation. Processing times, temperatures, ingredients and approved methods should be followed exactly because improper canning can create serious food-safety risks.

Canning altitude limit

For pressure canning, the Power Pressure Cooker XL is specified for operation only up to 2,000 feet above sea level.

Do not use the cooker for pressure canning above that altitude.

Canning pressure

The Canning program uses an 80 kPa setting. The guide equates 80 kPa to approximately 11.6 PSI.

Raw packing vs. hot packing

Raw packing means placing fresh, unheated food directly into canning jars.

Hot packing means pre-cooking the food before placing it into the jars.

The manual notes that hot packing helps reduce the amount of air remaining in the food.

For either method, liquids added to foods should be heated to the boiling point before filling.

Preparing Jars for Pressure Canning

The PPC770 accommodates up to four 16-ounce (1-pint) wide-mouth jars per canning session.

Clean the jars

Wash empty jars:

• By hand in hot water with detergent, or
• In a dishwasher.

Rinse them thoroughly.

Hard-water deposits can be removed by soaking the jars for several hours in a mixture containing 1 cup of 5% acidity vinegar per gallon of water.

Prepare the lids

Inspect the self-sealing metal lids carefully.

Do not use lids that are:

• Old
• Dented
• Deformed
• Missing sealing material
• Otherwise damaged

Prepare the lids according to the lid manufacturer’s instructions.

Pressure Canning Process

The canning guide instructs users to begin with a pre-tested and approved pressure-canning recipe.

Step 1: Prepare the food

Choose fresh ingredients and prepare them exactly as required by the tested recipe.

Step 2: Fill the jars

Fill clean 16-ounce jars while leaving approximately 1 inch of headspace at the top.

Step 3: Remove trapped air

Run a flexible, nonporous spatula between the food and jar to release trapped air bubbles.

Step 4: Install the lids and bands

Place the clean lid on the jar and install the screw band.

Hand-tighten the band.

Do not retighten the band after the jars have been processed.

Step 5: Load the cooker

1. Put the inner pot into the cooker base.
2. Place the wire rack at the bottom of the inner pot.
3. Put the filled jars on the rack.
4. Load no more than four 16-ounce jars.

Step 6: Add hot water

Pour hot water around the jars until the water reaches approximately one-quarter of the way up their sides.

For four 16-ounce jars, the manual gives approximately 6 cups of water as the reference amount.

Fewer jars may require additional water.

Step 7: Lock the lid

Install and lock the cooker lid, then plug the appliance into the outlet.

Step 8: Select Canning / Preserving

Press CANNING/PRESERVING.

The program automatically sets pressure to 80 kPa.

Adjust the cooking time according to the tested canning recipe.

Step 9: Complete the cycle and release pressure

When processing is finished:

1. Press Cancel.
2. Unplug the cooker.
3. Move the Pressure Valve to Open using the safe pressure-release method.
4. Allow all steam to escape.
5. Carefully remove the lid.

Step 10: Remove the jars

Use canning tongs to lift the hot jars.

Place them on a heat-resistant surface and allow them to cool to room temperature.

Step 11: Check the seals

Once the jars are completely cool:

1. Remove the screw bands.
2. Press the center of each lid.
3. A correctly sealed lid should not flex or spring.

If a jar has not sealed correctly, the guide says it should not be stored as a shelf-stable product.

Step 12: Store properly processed jars

Store properly processed jars in a cool, clean and dry location.

Inspect jars, lids and bands for damage before reuse.

Pressure Canning Processing Times

The manual’s canning table uses an 80 kPa pressure setting for the listed foods.

The manual also directs readers to the National Center for Home Food Preservation or a local county extension agent for additional low-acid foods and processing methods.

Safe Canning Tips

The canning guide gives several important precautions:

• Do not use over-ripe fruit.
• Do not increase the amount of low-acid ingredients beyond the tested recipe.
• Do not over-season with spices.
• Do not add butter or fat.
• Do not use flour, starch, pasta, rice or barley as thickeners.
• Use only the thickener specified in an approved recipe.
• Add lemon juice, vinegar or citric acid when the recipe requires it.

Technical Specifications

Troubleshooting Common Problems

Steam is leaking from around the lid

Possible causes addressed by the manual include an incorrectly seated lid, improperly installed gasket or incorrectly assembled Float Valve.

Check that:

1. The gasket is correctly installed.
2. The lid is properly seated.
3. The Float Valve moves freely.
4. The Float Valve silicone gasket is installed correctly.

Gently pressing down on a newly seated lid may help establish the seal.

Cooker will not build pressure

Check the lid, rubber gasket and Float Valve first.

The Float Valve must move freely, and the pressure valve and release passages must remain clear of food debris.

The inner pot must also be properly seated on the heating plate.

Lid will not open

Do not force it.

Resistance can indicate that pressure remains inside the cooker.

Press Keep Warm/Cancel, safely move the Pressure Valve to Open with tongs or another kitchen tool, wait until all steam has escaped, and only then attempt to open the lid.

Display shows a rotating pattern

This is normal during the pressure-building stage.

After pressure has been reached, the rotating display stops and the cooking countdown begins.

Cooker takes several minutes before the timer starts

The cooking timer does not begin until the cooker has reached the required pressure or temperature.

Full pressurization can take up to 17 minutes.
