is any food or moisture, wipe the surface clean before proceeding.

2. Check the sealing ring, float valve, anti-block shield, water collector and exhaust valve in order to ensure
they are clean and properly installed.
3. Remove the inner pot from the pressure cooker and place the food contents/ingredients in the
container, making sure you don’t exceed the marked maximum capacity.
4. Place the inner pot back into the pressure cooker.
5. Place the lid on the pressure cooker, aligning the with the on the lid. Turn the lid clockwise to align

Safely Removing the Lid
Auto-Off Safeguard
NOTE: For your safety, open the lid slowly. Do not open the lid before all pressure has escaped through the exhaust valve and the
float valve has completely fallen back into the lid.
1. Let the cooker cool down on its own. Wait approximately 10 minutes until the float valve drops down
before opening the lid.
2. Turn the lid counterclockwise to unlock, then carefully lift the lid away from your face. Keep the lid over
the pressure cooker to allow any remaining steam to escape.
3. Completely remove the lid, keeping your face and exposed skin at a safe distance from the heat
released from the pressure cooker.
1. If set to the (steam seal), carefully move the exhaust valve to (steam exhaust), allowing the
steam to gradually escape from the pressure cooker (for solid food only).
2. The float valve will drop back into the lid when it is safe to open the pressure cooker.
3. Turn the lid counterclockwise to unlock, then carefully lift the lid away from your face. Keep the lid over
the pressure cooker to allow any remaining steam to escape.
4. Completely remove the lid, keeping your face and exposed skin at a safe distance from the heat
released from the pressure cooker.
Once cooking is complete, turn off the pressure cooker’s power by unplugging the power cable. You can
safely remove the lid following either of the two methods described below:
Method 1:
Method 2:
The pressure cooker will automatically power off if it begins to overheat in order to protect the unit from a
circuit overload or a potential fire. This is an irreversible safeguard that cannot be overridden.

CLEANING & MAINTENANCE
Inner Pot
Sealing Ring Cleaning
Float Valve
Water Collector
Do not use abrasive detergents or scouring pads to remove burnt food. Soak the inner pot in warm, detergent
water, then remove excess food with a regular sponge.
Rinse and dry the container thoroughly before next use.
After each use, clean off excess oil and food from the lid and sealing ring with detergent and a soft brush.
To remove the sealing ring, gently pull the ring upwards, removing it from the inner lip of the lid. To re-install
the ring, gently press the ring into the inner lip of the lid, making sure it’s fully wrapped around the inner
metal ring of the lid.
Keep the float valve clean between uses. To remove, gently slip off the plastic covering and slide the pin out
of the lid. Soak the plastic cover and plug in warm soapy water to clean, then rinse and dry thoroughly. To re-
install the pin, slide the pin back into the lid from the top, then re-apply the plastic cover.
The water collector contains the excess steam when the pressure cooker is in use. To keep odor-free, make
sure to empty and wash the water collector with detergent and warm water. Rinse and dry thoroughly before
replacing the water collector in the pressure cooker.
NOTE: Allow the pressure cooker to cool down before cleaning any part of the unit.
NOTE:
•For your safety, check to ensure the sealing ring is properly installed before each use.
•Do not operate the pressure cooker if the sealing ring is damaged.
