• DO NOT place frozen meats or
sh into the pressure cooker;
always make sure meat and sh
are thawed before cooking.
• 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.
• The silicone sealing ring creates
a pressure seal between the lid
and the pot. Keep the sealing
ring completely clean and free
from any cracks or deterioration.
• DO NOT break the silicone
sealing ring. Do not replace it
with other rubber sealing rings
or use a tension belt to make the
pressure cooker seal.
• Check and wash anti-clog lter
and pressure release valve
regularly to avoid any blockage.
• DO NOT attempt to open the lid
while the oat valve is still 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.
• DO NOT attempt to move
the pressure cooker while it is

nished and before opening the
lid.
• Clean and properly place the
water collection cup 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.
• Unplug from outlet when not in
use and before cleaning. Allow
it to cool before putting on or
taking o parts.
• 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

How Does it Work?
1. To open the lid, turn the latch
counterclockwise so that the
“Open” mark aligns with the
(arrow symbol) then pull up on
the lid handle.
2. Check all parts on the lid to make
sure they are properly assembled.
Make sure there is no debris blocking
the oat and anti-clog lter, and that
they are able to easily move up and
down. Check the sealing ring to see
if it is properly positioned along the
rack.
3. Add ingredients to the inner
pot. Ingredients and water/
liquid should not exceed ⅔ of
the inner pot capacity. When
cooking dry ingredients such as
rice or beans, do not ll the past
½ the capacity of the inner pot.
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.
• The minimum amount of liquid
needed for cooking is 4 cups/1500
mL. (This may vary depending on
the recipe you are following.)
4. Wipe away any excess moisture
or debris from the exterior of
the inner pot, then place it into

PRESET COOKING
FUNCTIONS FOR PRESSURE
COOKING
NOTE:
• It may take anywhere from 5 to 35
minutes to pressurize depending on
the amount of food in the inner pot.
The more food inside the pot, the
longer it will take to reach optimal
pressure.
• CAUTION: While the cooker is
pressurizing, it may automatically
release excess pressure through
the pressure release valve. This is
a built-in safety feature to ensure
the pressure cooker is maintaining
a safe pressure level for proper
operation. This may also happen if
there is less than 4 cups of liquid in
the inner pot.
