Setup and First Use

- Power Connection: Connect the power cord to the lunch box and then to a suitable power outlet.
Operating Instructions
General Operation:
- Add the appropriate amount of water to the main unit's base before placing inner pots. The amount of water depends on the cooking function and desired cooking time.

- Once cooking is complete, the unit may switch to a "Keep Warm" function or turn off. Unplug the unit and carefully remove the inner pots.
Using the Vacuum Pump:
The included vacuum pump and double-layer silicone lid help keep food fresh for longer. After cooking or preparing food, place the silicone lid on the inner pot and use the vacuum pump to extract air from the pot. This creates a partial vacuum, which can slow down spoilage. Important: Always remove the vacuum pump and silicone lid before heating or cooking.
