5. Operating Instructions

5.1 Steaming Food

1. Prepare Food: Wash and prepare your food items. Cut larger items into smaller, uniform pieces for even cooking.
2. Load Baskets: Place food directly into the steaming baskets. For rice, use the provided rice bowl and place it within a steaming basket. Ensure food is not packed too tightly to allow steam circulation.
3. Assemble Steamer: Place the drip tray on the base unit, then stack the loaded steaming baskets. Place the lid securely on top.
4. Fill Water: Ensure the water reservoir is filled to an appropriate level for your cooking time. For longer steaming, fill to the MAX line.
5. Plug In: Connect the power cord to a suitable electrical outlet. The power indicator light will illuminate.
6. Set Timer: Turn the timer dial clockwise to the desired steaming time. Refer to the cooking guide below for recommended times. The steamer will begin heating immediately.
7. Monitor Water Level: During extended cooking, monitor the water level indicator. If the water level becomes low, you can refill through the external water inlet without removing the baskets.
8. Completion: The steamer will automatically shut off when the timer reaches zero or if the water reservoir becomes empty (boil-dry protection). The power indicator light will turn off.
9. Serve: Carefully remove the lid (steam will be hot) and then the baskets using oven mitts. Serve food immediately.

If the water level drops too low during cooking, the steamer's boil-dry protection will activate, and the unit will shut off. To continue steaming, you can add water through the external water inlet:

• Carefully pour water into the water inlet located on the side of the base unit.
• Monitor the water level indicator to ensure you add sufficient water.
• Once enough water is added, the steamer will resume operation if the timer has not expired.
