Features

How long does the Duo Series Pressure Cook?
With the Duo Series you can Pressure Cook for a maximum of 4 hours.
How many temperature Settings does the Automatic Keep Warm have?
The ‘Keep Warm has 3 temperature settings to maintain food at different serving temperatures.
How full (food & liquid) can the inner pot be for pressure cooking?
For all pressure-cooking programs the total amount of pre-cooked food and liquid in the inner pot should not pass the 2/3 line.  When preparing food that expands during cooking such as rice, beans or vegetables, the inner pot should not pass the ½ line.  Over filling the inner pot may risk clogging the steam release and developing excess pressure.  This may cause leakage, personal injuries, or damage to the cooker. Note: Fill level warnings do not apply to non-pressure cooking programs.
How should the Steam Release handle be positioned for pressure-cooking?
The steam release handle must be in the Sealing position for pressure-cooking.
What is the maximum time for the Sauté function?
The maximum time is 30 minutes as a safety precaution. Note: Never have the lid on when Sautéing.
What are the different Sautéing functions?
One may select ‘Normal for regular browning/searing, ‘Less for simmering or thickening a sauce or ‘More for stir-frying or blackening meat.  To change the cooking temperature, press Sauté repeatedly to select between the different settings.
Should I use the Lid for the Sauté function?

No, do not use the Instant Pot® lid with the Sauté function as the cooker requires sufficient venting to prevent overheating.

How many hours can the Instant Pot® Slow Cook for?
The Slow Cook can be set from 0.5 – 20 hours.
How many temperature Settings are there in the Slow Cook program?
There are 3 temperature settings
How does the Slow Cook function work in comparison to a slow cooker?
The Instant Pot® Slow Cooking function controls the slow cooker with 3 different temperature settings.  For instance, medium is 194~205°F/90~96°C; whereas, most conventional slow cookers do not actually control the temperature levels, they only apply different heating intervals or intensity. The difference between the High and Low settings of most conventional slow cookers is only in the time it take to reach 212°F or 100°C. The 3 temperature ranges in the Instant Pot® are:
  • Less: 82-87.8°C/180-190°F (low setting in a slow cooker)
  • Normal: 87.8~93°C/190-200°F (medium setting in a slow cooker)
  • More: 93~99°C/200~210°F (high setting in a slow cooker)
Note: For non-pressure cooking one may use the Instant Pot® glass lid.
How long is the Fermentation time for making Yogurt?
Fermentation is up to 99.5 hours at 2 temperatures.
How do I know the Pressure-Cooking process has started?
10 seconds after pressing the settings, the cooker will beep 3 times and will display ON to indicate that the cooker has entered the preheating cycle.  Depending on the amount of food and its temperature, the preheating cycle can take a few minutes to 40 minutes or more.  As the cooker heats up and pressure builds, the float valve rises.  When working pressure is reached, the cooker enters the cooking cycle and displays the remaining cooking time in minutes.  When the cooking cycle is completed, the cooker will beep and switches to the Keep Warm mode  (Note: Only if the Keep Warm function is turned on).
What is the Steam Rack for?
The Steam Rack is used on the bottom of the inner pot when steaming vegetables or to elevate dishes outside of the liquid in the inner pot.
Is the Steam Rack stainless steel?
Yes, it is made from food grade 304 (18/8) stainless steel, compliant to FDA food safety standards.
What is the maximum time for the Sauté function?
The maximum time is 30 minutes as a safety precaution. Note: Never have the lid on when Sautéing.
Why does Keep Warm setting have a maximum time of 24 hours?
The Keep Warm will automatically shut off after 24 hours for safety and energy consumption reasons.
How do I know if the Keep Warm is ON?
For Duo, the Keep Warm icon will be lit (Note: If the Keep Warm function is turned ON).
How many temperatures are available in the Warm setting?
There are 3 temperature settings available, low, medium and high.
How much liquid is required in the inner pot for pressure-cooking?
For pressure-cooking always add at least 1.5 – 2.5 cups / 355 – 473 ml (depending on quart size) of water or other liquids with a thin, watery consistency so enough steam can be generated to cook under pressure.  These liquids include cooking sauces, wine, beer, and stocks. Note: Oils and oil-based sauces do not have sufficient water content and do not account for the required liquid volume.

Maintenance

How often should the Sealing Ring be cleaned?

It is not necessary to remove the sealing ring after each use.  One should remove the sealing ring and clean the sealing ring following every 5-6 uses or if any food that splatters was prepared.

How often should the Sealing Ring be replaced?

The sealing ring is made from food grade silicone and is extremely durable.  Under normal conditions it should be fine for 18 – 24 months.  If you notice cracks, leaking or deformation in the sealing ring, it should be replaced.  However, the sealing ring is porous and may absorb odors and become discolored.  To avoid discoloration and odors, one may wish to change the sealing ring every 6 – 12 months.

Can I use another brand of Sealing Ring?

Unapproved and unauthorized sealing rings are not manufactured, tested or certified by Instant Pot®; as such, we are unable to confirm if they meet Instant Pot’s established standards.  The use of third party sealing rings may have unexpected effects on your cooker, and will void the Instant Pot® warranty.  Instant Pot® recommends only using Instant Pot® branded sealing rings.

Product Overview

Why do you refer Instant Pot® as the SMART cooker?
Instant Pot® is a programmed smart cooker that has preset cooking instructions for food ingredients and cooking methods. For the Duo, it remembers the last 3 sets of customizations in “Less”, “Normal”, and “More” on all cooking programs for a more personalized cooking experience. Note: To return to the factory default setting for a specific cooking program, return the cooker to Standby mode displaying OFF, then press and hold the cooking program key until the cooker beeps. For a full reset of all cooking programs and other system settings, return the cooker to Standby mode displaying OFF, then press and hold the Cancel key until the cooker beeps.

Proper Usage

Can I make cooking adjustments after the cooking process has started?

The Duo Series allows one to easily adjust settings even after the cooking is in progress.

How does the Cancel key work?
The cancel function ends a cooking program at any time or returns the cooker to the standby mode displaying OFF.  It can also be used to reset the cooker to full factory default
The Steam Release Handle is loose, is this normal?
Yes, the Steam Release handle should not lock tightly into the lid, it must fit loosely.
What is the Condensation Collector for?

The condensation collector traps any excess liquid to prevent it from spilling onto the counter.

What is the Anti-Block Shield?
The Anti-Block Shield is the round component with 6 holes under the lid.  The Anti-Block Shield prevents food particles from blocking the steam release valve.
Does the Anti-Block Shield need to be removed?
Yes, the Anti-Block Shield must be removed and cleaned after each use, especially following the preparation of foods that may splatter. To remove: Using your thumb, push the side of the Anti-Block Shield towards the lid rim and lift up with some effort. The anti-block shield should pop out.  To install: Position the Anti-Block Shield in place and push down.
How do I stop a program after it has started?
Once the cooking process has started, you can press Cancel at any time to end the program.  The cooker will then go into the Standby mode.
What is the difference between Natural Release and Quick Release?
Natural Release: Allows the cooker to cool down naturally until the float valve drops down.  This may take 10 to 40 minutes, or even longer, depending on the amount of food in the cooker.  Place a wet towel on the lid to speed up the cooling process (Note: Do not cover the steam release valve).  Once the cooking process is completed, turn OFF the Keep Warm mode if it is ON. Quick Release: Turn the steam release handle to the venting position to let steam out until the float valve drops. Never pull out the steam release handle while it is releasing steam as escaping steam is extremely hot and can cause scalds. For food with large liquid volume or starch content, use the Natural Release as thick liquid may splatter out.
How do I know if I should use the Natural Release or Quick Release?
Start by referring to the recipe.  The Quick Release method is used for delicate dishes such as custards and fresh vegetables and the Natural Release method is used for meats, soups and grains.
What do I do if the Float Valve is stuck?
Move the Steam Release valve to the Venting position.  Once all the steam is released, push the float valve down with a pen or long stick.
Can one Deep Fry in the Instant Pot®?

One cannot deep fry or pressure fry in the cooker with oil.

Can one do Canning with Instant Pot®?
There are two types of canning: boiling-water canning at 100°C/212°F (for acid fruits, tomatoes, pickles and jellied products) and pressure canning at 115~121°C/240~250°F (for low acid vegetables, meat and poultry). Please refer to “USDA Complete Guide to Home Canning” for more details. Instant Pot® can be used for boiling-water canningThe Instant Pot® current product line is regulated by a pressure sensor instead of a thermometer; the altitude of your location may affect the actual cooking temperature.  We recommend to not use Instant Pot® for pressure canning.

What does Ov Ht refer to?

Instant Pot® is built with a burn-protection mechanism.  When a high temperature 140C/ 284F is detected on the bottom of the inner pot, the burn-protection mechanism suspends heating to avoid food burning.

The only exception to the burn-protection mechanism is with food that has a very high starch content. For instance, if you add flour in your chili, the flour will sink to the bottom, solidifies at low temperatures and can block heat dissipation. In this situation, we suggest you add flour to the chili after initial cooking and perhaps cooking it for an additional one to five minutes to allow thickening of the chili.

What accessories are included with the Duo?

Accessories include – stainless steel (18/8) steam rack with handles to lower and lift food, condensation collector, rice paddle, soup spoon, and measuring cup.

What accessories are recommended for use in Instant Pot®?

Instant Pot® recommends to only cook in the Instant Pot® stainless steel or ceramic non-stick inner pots for best results. Other brands may not have the correct curvature to match the heating element. Accessories and parts not branded Instant Pot® or recommended by Instant Pot® may cause the cooker to malfunction.
