- Placement: Place the power base on a dry, flat, stable, and heat-resistant surface, away from the edge of the countertop. Ensure the power cord is not dangling where it can be pulled or tripped over.

Maintenance
- Cleaning the Exterior: Unplug the kettle and allow it to cool completely. Wipe the exterior with a soft, damp cloth. Do not use abrasive cleaners or scouring pads.
- Descaling: Over time, mineral deposits (limescale) may build up inside the kettle, especially in hard water areas. To descale:
- Fill the kettle with a mixture of one part white vinegar and two parts water.
- Boil the mixture and let it stand for at least 30 minutes, or longer for heavy buildup.
- Pour out the mixture and rinse the interior thoroughly with fresh water several times.
- Alternatively, use a commercial descaling solution designed for kettles, following the product instructions.
- Storage: Ensure the kettle is clean and dry before storing. Wrap the power cord around the base for tidy storage.
