• Always check the pressure anti-block shield, lid lock, and heating plate for any damage or clogging before
each use.
• Be aware that certain foods such as applesauce, cranberries, pearl barley, oatmeal or other cereals, split
peas, noodles, macaroni, rhubarb, spaghetti, and froth may clog the anti-block shield. When cooking these
foods, make sure to only fill the pressure cooker’s inner pot with no more than 3 liters of contents (do not
completely fill).
• Keep all parts of the pressure cooker clean after each use in order to prolong and maintain the
appliance’s service life.
• DO NOT fill the unit over 2/3 full. When cooking foods that expand during cooking such as rice or dried
vegetables, do not fill the unit over ½ full. Overfilling may cause a risk of clogging the vent pipe and
developing excess pressure.
• This device cooks with high pressures. Improper use may result in serious burning or scalding.
• DO NOT use the pressure cooker to deep fry or pressure fry foods with oil. Doing so may cause a fire
and/or serious injury.

cool off before removing parts or cleaning.
• The use of accessory attachments is not recommended, as this may cause injuries.
• A short power supply cord is provided to reduce injuries resulting from entanglement and tripping. An
extension cord may be used if proper care is exercised. If an extension cord is used, the electrical rating
of the cord must be at least 20 A and 120 V. The extension cord must be arranged so that it will not drape
over the edge of a table or counter where it can be pulled by children or accidentally tripped over.
• DO NOT attempt to modify the fitted plug in any way.
• This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of electric

Safely Removing the Lid
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.
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:
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.
Method 2:
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.
Auto-Off Safeguard
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.
