Depressurizing the Cooker (Venting Methods)
Quick Release
Important: Do not use quick release when cooking high starch foods (e.g.,
soups, stews, chilis, pasta, oatmeal and congee) or when cooking foods that
expand when cooked (e.g., beans and grains). To release pressure quickly,
press the Quick Release Button down until it locks into place.
Pressure will be released through the Steam Release Valve. When the cooker
is safely depressurized, the Float Valve will lower into the lid.
If quick venting creates undesirable steam spatter, close the Quick Release
Button by turning it counter-clockwise until it pops up, and try again after
a few minutes. If spatter continues, use the Natural Release procedure to
release remaining pressure.
Do NOT lean over steam release
valve.
