Setup
- Unpack: Carefully remove the kettle and all accessories from the packaging. Retain packaging for future storage or transport.
- Initial Cleaning: Before first use, fill the kettle with clean water up to the MAX fill line. Boil the water, then discard it. Repeat this process 2-3 times to remove any manufacturing residues.
- Placement: Place the power base on a stable, flat, heat-resistant surface, away from the edge of the counter. Ensure the power cord is not dangling where it can be pulled or tripped over.
- Connect Power: Plug the power cord into a suitable grounded electrical outlet (AC220-240V 50/60Hz).
Operating Instructions
- Fill the Kettle: Open the lid and fill the kettle with the desired amount of fresh water. Do not fill below the MIN mark or above the MAX mark (0.8L capacity). Overfilling may cause boiling water to spill out.
- Close Lid: Ensure the lid is securely closed before placing the kettle on the power base.
- Place on Base: Position the kettle onto the power base. The 360° rotational design allows for easy placement from any angle.
- Switch On: Press the power switch down. The power indicator light will illuminate, indicating that the kettle is heating.
- Boiling: The 1000W high power heating element will rapidly boil the water, typically within 4-6 minutes.
- Automatic Shut-off: Once the water has boiled, the kettle will automatically switch off, and the power indicator light will extinguish.
- Pouring: Carefully lift the kettle from the base and pour the hot water. Be cautious of steam escaping from the spout.
- Re-boiling: If you need to re-boil water, wait a few moments for the internal thermostat to reset before pressing the power switch again.


Maintenance
Regular cleaning and maintenance will prolong the life of your electric kettle.
Cleaning the Exterior
- Always unplug the kettle and allow it to cool completely before cleaning.
- Wipe the exterior of the kettle with a soft, damp cloth. Do not use abrasive cleaners or scouring pads, as they may scratch the stainless steel finish.

Descaling (Removing Limescale)
Limescale buildup can affect the kettle's performance and heating speed. Descale your kettle regularly, especially in hard water areas.
- Fill the kettle with a mixture of one part white vinegar and two parts water, or use a commercial descaling solution according to its instructions.
- Bring the mixture to a boil and then let it stand for at least 30 minutes, or longer for heavy buildup.
- Pour out the mixture and rinse the kettle thoroughly with fresh water several times.
- Boil a fresh kettle of water and discard it before using the kettle for beverages.
