How do I release pressure from the unit?

To Quick Release pressure from the unit, slide the pressure release valve to the VENT position by using the tab on the end. Be sure to keep your face away from the valve, as a quick burst of steam will spurt out of it. When all the steam is released, the red float valve will drop down and the unit will be ready to open. DO NOT place your hand over the valve because hot steam will release immediately. To Natural Release pressure from the unit, DO NOT slide the pressure release valve to VENT. Instead, when the cook time is complete, wait for the unit to naturally release the pressure on its own. This can take up to 20 minutes, depending on the amount of liquid and food in the unit. During this time, the unit will switch to Keep Warm mode and the timer will start counting up. When Natural Release is complete, the red float valve will drop down.
