Operating Instructions
The WMF Lono Ribbed Electric Grill features a variable temperature control for optimal grilling results.
- Preheating: Turn the temperature control dial to the desired setting. The LED lighting will illuminate, indicating the grill is heating. Allow 5-10 minutes for the grill to reach the set temperature.
- Grilling: Once preheated, place food directly onto the grill plate. The non-stick surface allows for grilling without added fat, if desired.
- Temperature Adjustment: Adjust the dial as needed during grilling to achieve preferred doneness. Higher settings are suitable for searing meats, while lower settings are ideal for vegetables or keeping food warm.
- Completion: After grilling, turn the temperature control dial to the 'OFF' position and unplug the appliance. Allow the grill to cool completely before cleaning.
