IMPORTANT SAFEGUARDS
Please read, understand, and comply with all the instructions provided in this manual
before using the device. Failure to comply with the instructions given in this manual
and/or using the device in ways other than the ones mentioned in this manual may
result in serious injury and/or damage to the product.
Safety Use & Care
• DO NOT touch hot surfaces. Use handle and pot holders when necessary.
• To protect against electrical shock, do not immerse cord, plugs, or the unit in water
or other liquid.
• Close supervision is necessary when any unit is used by or near children.
• Unplug from outlet when not in use and before cleaning. Allow it to cool before
putting on or taking o parts.
• DO NOT operate the pressure cooker with a damaged cord or plug, after the unit
malfunctions or if it has been damaged in any manner. If the unit is malfunctioning,
please contact customer support.
• Using other accessories that are not compatible with the pressure cooker is not
recommended. Doing so may damage the unit or cause injury.
• The pressure cooker is intended for indoor use only.
• DO NOT place on or near a hot gas or electric burner and/or in a heated oven.
• Extreme caution must be used when moving the pressure cooker with hot oil or
other hot liquids inside.
• To disconnect the unit from a power source, press ‘Start/Cancel’, then remove the
plug from the outlet.
• Always check the pressure release valve and oat valve for any clogging before use.
• DO NOT place any object above the pressure release valve while the steam is being
released from the pressure cooker.
• DO NOT use the unit for anything other than its intended use.
• If you cook meat with a casing, such as sausage, swelling can occur when cooked
under pressure. Piercing the skin after cooking can lead to bursts of hot liquid.
• DO NOT lean over the pressure cooker at any time while it is cooking.
• This pressure cooker should not be used for any medical purposes. It is not
designed to reach the required temperature for sterilization.
• The silicone gasket creates a pressure seal between the lid and the pot. Keep the
gasket completely clean and free from any cracks or deterioration.
• DO NOT break the silicone gasket. Do not replace it with other rubber gaskets, or
use a tension belt to make it seal.
• It is extremely important to ll the pressure cooker with liquid prior to operation.
Never cook without liquid; doing so can cause the unit to overheat and damage the
safety mechanisms. In case of overheating, never remove the pressure cooker from
the heat source. Instead, shut it o immediately and let it cool.
• Make sure all parts of the pressure release valve and oat valve are clean and
properly assembled.
• DO NOT alter the safety mechanisms or attempt to repair the pressure cooker as
this will void the warranty. Please refer to the Care & Maintenance section on page
16 on how to maintain the pressure cooker.
• DO NOT place the unit close to ammable materials, heating units, or wet
environments.
Safety Information

5
• Check and wash the anti-clog lter and pressure release valve regularly to avoid
blockage.
• DO NOT open the lid when the oat valve is up.
• DO NOT put anything on or use other objects to replace the pressure release valve.
• Never use a towel to clog the gap between the lid and edge of the Housing.
• The bottom of the inner pot and heating plate should be kept clean. Do not put the
inner pot on other heat sources. Do not replace the inner pot with other containers.
• Only use wood or plastic ladles or spoons to prevent the stainless steel pot from
wearing out.
• DO NOT attempt to move the pressure cooker while it is cooking; wait until it cools
down to move it. Move the unit using the built-in handle; do not try to hold it from
the lid handle.
• DO NOT disassemble the unit on your own or try to replace with parts from
dierent brands.
• Make sure air/pressure discharges completely before opening the lid.
• Clean and properly place water the collection cup and lid before each use.
• You may experience some smoke coming out the unit during the rst few uses due
to the initial heating of the materials; this is normal.
• DO NOT let power cord hang over the edges of tables or counters, or touch hot
surfaces.
• A short power supply cord is provided to reduce injuries resulting from
entanglement and tripping. If an extension cord is used, the electrical rating of the
cord must be at least 120V/20A. The extension cord must be arranged so that it will
not hang over the edge of a table or counter where it can be pulled or accidentally
tripped over.

Before First Use (cont.)
Safely Releasing Pressure
CAUTION:
• DO NOT lean over the pressure cooker or place exposed skin over the pressure
release valve when releasing the pressure inside the pot.
• DO NOT open the lid until the pressure inside the pot has been completely
released. For your safety, the lid will remain locked until the oat valve drops
down.
• DO NOT, under any circumstance, force the oat valve down while it is still up.
There are 2 ways to release the pressure inside the pot after cooking has nished.
Natural Release:
1. Allow the pressure cooker to rest for about 10–15 minutes.
2. After that time, press the pressure release button to release any remaining
pressure.
3. Open the lid once the oat valve has gone down. Remember to press the valve
reset button after releasing all of the pressure inside the pot.
Quick Release:
1. Press the pressure release button immediately after cooking has nished.
2. Allow the pressure to release until the oat valve goes down.
3. Open the lid once the oat valve has gone down. Remember to press the valve
reset button after releasing all of the pressure inside the pot.
NOTE:
The quick release method is not suitable for foods that have a large liquid volume
or a high starch content (e.g., soups, porridge, fruit jams). It is recommended to use
the natural release method when cooking liquids such foods. Immediately releasing
pressure may result in food spraying out through pressure release valve.
3. To close the lid, place it back down onto the pressure cooker housing. Grip the lid
handle and twist it clockwise so that lines up with the white mark at the top
of the control panel.
4. Plug in the pressure cooker and press ‘Steam.’
5. Press ‘Start/On’ to start cooking. The display will show “00:05” to indicate that
the pressure cooker is heating up. Trace amounts of steam will release from
either valve until the oat valve pops up during this initial heating process. Once
the unit reaches optimal cooking pressure, the unit will beep once and the display
will show “P0:05.”
6. When the cooking program has nished, the pressure cooker will beep 5 times.
Press ‘Stop/Cancel’ to set the pressure cooker to standby mode.

11
Preparing to Cook
NOTE:
• Thoroughly wash the inner pot before each use.
• The minimum amount of ingredients needed to cook in the pressure cooker is ⅕ of
the capacity of the inner pot, which is roughly 1 cup.
1. Open the lid and remove the inner pot from the pressure cooker.
2. Prepare food according to recipe directions and place food and liquids into the
pot. Food and water should not exceed ⅘ height of the pot. If the food easily
expands in water, do not let it exceed ⅗ height of the inner pot.
3. Before placing pot back into the pressure cooker, be sure to wipe down the
bottom of the pot and the surface of the heating plate with a dry cloth. Make sure
the unit is o when placing the pot back into the pressure cooker housing.
4. Place the pot back into the pressure cooker and close the lid. Turn the lid handle
counterclockwise so that is lined up with the white mark at the top of the
control panel.
