5.2 Releasing Pressure
There are two methods for releasing pressure:
- Natural Release: Allow the cooker to cool down naturally. The pressure will dissipate gradually. This method is recommended for foamy foods or large cuts of meat.
- Quick Release: Carefully turn the pressure release valve to the "Venting" position. Steam will rapidly escape. Keep hands and face away from the steam. Use a utensil to turn the valve to avoid direct contact.
The lid can only be opened once the float valve has dropped down, indicating that all pressure has been released.
