User Guide for NASA Electric NS-520 Tea Maker
To use the NASA Electric NS-520 Tea Maker, place the power base on a flat, stable surface. Before the first use, fill the kettle with water up to the indicated level, boil it twice, and discard the water to remove any manufacturing residue or odor.
For daily operation, fill the kettle with water, ensuring the level remains between the MIN and MAX marks. Close the lid securely, place the kettle on the power base, and connect the appliance to a power outlet. Once the display enters standby mode, touch the corresponding icon to start boiling. After the water reaches boiling point, the tea maker automatically switches to the keep-warm mode, maintaining the water at approximately 90°C for up to 2 hours. The temperature can also be adjusted between 40°C and 93°C according to your preference.
To brew tea, open the tea filter, add the desired amount of loose tea leaves, and pour hot water into the teapot up to the maximum level. Lock the filter, align the lid properly with the sealing ring, and place the teapot on the warming plate. If the kettle is not positioned correctly on the base, the display shows E1, while E3 indicates that the water level is below the minimum requirement. To cancel any active function, simply touch or press and hold the corresponding control icon.
