5 Product setup

Setup guide

1. The dispenser should be 20cm from the wall to optimize cooling performance.
2. If a small cup is used, the removable drip tray can be adjusted to a higher position by pulling it out and placing it at the higher position.

Important: Please let the product stand in an upright position for at least 2 hours before activating the cooling function. This product has a built-in compression cooling system.

Rinsing

(Takes approximately 1.5 hours or more)

For optimal performance, follow these steps for membrane rinsing before initial use or after replacing the filter. This process typically takes approximately 1.5 hours. To prevent the growth of microorganisms, place the product in a location that avoids direct sunlight.

1. Remove the tap water tank lid and lift the tank upwards. Fill the tap water tank with tap water and place it back to the machine. Then, place the lid back to the tap water tank properly.
2. Ensure the tap water tank is fully attached to the back panel to prevent improper water filtration or water leakage.
3. After installing the filtered water jug, long press the "?" button for 5 seconds. When you hear a "beep" sound, it indicates that the machine is working.
4. Ensure the filtered water jug is fully attached to the pedestal, otherwise, it will cause improper water filtration or water leakage.
5. During the progress from 0% to 80%, when you see the percentage flash and hear 3 beeps, please empty the filtered water jug.
6. When the "?" light flashes, you will hear 3 beeps. Empty the water in the tap water tank, refill it with fresh tap water up to the Max line, and place it back.
7. When the progress reaches "90%", and "?" flashes, you will hear 3 beeps. There is no need to empty the filtered water jug. Place a container with a volume of no less than 2 liters under the water outlet and press "?".
8. When it shows "100%", the rinsing process is complete. You can now start using the dispenser.

Important notes for flushing:

• Please follow the rinsing progress until it reaches "100%". During the rinsing process, in case of special circumstances, you can exit the rinsing program by long-pressing the "?" button for 5 seconds.
• During the water dispensing process from 90% to 100%, it is normal to hear a sucking sound. Please do not worry.
• During the first-time use, please check for any water leaks from or gathering around the dispenser. If you notice any strange noise, burnt smell, or smoke coming out from the machine, disconnect the cord immediately. In such cases, please contact customer services for further assistance.
• During the rinsing process, when air passes through high-precision filter elements, micro bubbles are generated, causing the water in the filtered water jug appears white and cloudy. This is a normal phenomenon.

Boiling point calibration

To prevent excess steam, the local boiling points should be checked and adjusted.

When the filtration process is complete and 100°C water is extracted for the first time, boiled water will flow out from the nozzle, and the boiling point calibration will be automatically completed. This procedure will last for approximately 60 seconds. Please ensure that a container with a volume of at least 500ml is placed under the nozzle during the procedure.

Note: There might be steam ejection during the boiling point calibration, please be aware of burn hazards.
