This appliance has a polarized plug (one blade is wider
than the other). To reduce the risk of electric shock,
this plug is intended to t into a polarized outlet only
one way. If the plug does not t fully into the outlet,

Steel Inner Pot installed.
2. This unit cooks under pressure and releases hot steam.
READ ALL instructions for proper use of this appliance to
avoid injury.
3. DO NOT cover the Pressure Release Switch/Valve or
Pressure Indicator. Before each use, ALWAYS check
the Pressure Release Switch/Valve and the Pressure
Indicator for blockage or obstructions. These should move
freely and should not be stuck in one position. Foods that
expand (pasta, rice, grains, beans, oatmeal, etc.) may
block these so clean thoroughly after each use.
4. Use caution when removing the Stainless Steel Inner
Pot from the unit, as the pot may be heavy and hot.
