User Guide for NASA Electric NS-519 Tea Maker
To use the NASA Electric NS-519 Tea Maker safely and efficiently, first place the power base on a flat and stable surface. Before the first use or after a long period of inactivity, fill the kettle up to the MAX level, boil the water once or twice, and discard it to remove any possible manufacturing odors or tastes.
For regular use, fill the kettle with an appropriate amount of water, ensuring that the level remains between the MIN and MAX indicators. Place the kettle securely on the base and connect the plug to the power outlet to activate the touch control panel.
In standby mode, select the desired function by touching the related icons. The water temperature can be adjusted between 45°C and 90°C. If no further command is entered within three seconds, the device will automatically start the heating process. During operation, the selected function indicator flashes, and after boiling, the appliance enters the keep-warm mode.
The keep-warm function is set to 2 hours by default and can be adjusted from 1 to 10 hours according to your preference. To stop the operation, simply touch the power icon. If the device remains unused for several minutes, it automatically enters sleep mode, and only the power indicator continues flashing.
To prepare tea, open the teapot filter and add your preferred amount of loose tea leaves. Slowly pour hot water into the teapot up to the marked level, then secure the filter and place the teapot on the kettle. This allows the tea to brew properly while maintaining its aroma and flavor.
