PRODUCT DETAILS

BEFORE USE

1. Placement Open the packaging box and remove the entire machine, placing it on a table. Take the water collection box from the package and insert it into the card slot of the machine.

2. Filling the water tank Open the upper cover of the water tank and lift out the tank. After rinsing the tank, fill it with an appropriate amount of water,  ensuring that the water level remains below the maximum scale but above the minimum line
   Pull up the handle to lift out the water tank

2b. Note: When filling the water tank, ensure that both the raw water area and the waste water area are filled up to the highest water level (as shown in the picture).

3. Powering on Place the water tank into the machine, close the top cover, and plug in the power.
   

4. Flushing the filter element
   Step 1: Unlock Press and hold the child lock button for one second to unlock the full screen.

Step 2 : Water production mode, the screen displays C1. The machine will start producing water for the first time. Please be patient and wait for approximately 13 minutes.

Step 3 : One-key emptying Press the button to empty the water in the pure water tank inside the machine.

Note: For the first use, it is recommended to repeat steps 1, 2, and 3 to flush the entire machine and the filter element. We suggest flushing with three buckets of water. This process may take some time, so please be patient. The first flush is to clean the filter element and pipeline, and the water may appear gray-black or bubble- like, which is normal. Continue to flush until the water runs clear.

SYSTEM USE

Water Dispensing Procedure:
To fill the water tank, repeat steps 2 and 3 in the “Before Use” section and plug in the machine. If the device is in sleep mode, simply touch any key on the screen to wake it up.

To unlock, press and hold the child lock button for 1 second.
To lock it, lightly touch the button.

UV Function:

1. After powering on, the UV sterilization indicator will light up, and the sterilization process will continue for 1 hour.
2. After each water production cycle, sterilization for 10 minutes will be carried out.
3. If the device is in standby mode for more than 50 minutes, the sterilization process will be performed for 10 minutes, and this cycle will repeat in standby mode.

Temperature Selection – you can choose between two temperature modes:

Shortcut Mode

Custom Mode
Click to add or subtract 1 degree; long press to speed up adjustment.

Shortcut Mode

Custom Mode

First Cup of Hot Water:
When the screen displays C3, the first cup of hot water will be at room temperature every time the power is turned on. So, when you want to drink hot tea, don’t worry. Just start the procedure again.

Example – water for hot tea:

Q: Why isn’t the water hot?

A: No need to panic! The system is designed this way. Simply run the procedure again to obtain hot water.

 SYSTEM MAINTENTANCE

If you see the screen displaying C1 , the machine is currently producing water. You may not be able to dispense water at this moment, so please be patient. After waiting for approximately two minutes, you can try dispensing water again.

When the screen displays C2, it means that the water tank is running low (when the water level falls below the water level line). You can resolve this issue by opening the top cover of the water tank, lifting out the water tank, pouring out the remaining water, and filling it up with new tap water. After you close the machine and its top cover, the machine will return to normal use (note: if you recycle the old water this can cause the membrane to foul over time).

If the screen displays E1, it indicates a system malfunction, and the fault light will flash. To fix this, you need to put the water tank back into the machine and cover it with the water tank cover. This will eliminate the alarm and allow the machine to continue functioning normally.

DAILY MAINTENANCE

1. Please wipe the machine with a soft cloth.
2. For stubborn stains or dust, use a soft cloth with warm water.
3. Do not use volatile liquids like alcohol, gasoline, paint thinner, polishing powder, or other materials, as they may damage the machine’s surface.
4. Do not wash the exterior or interior of the product with water. Rinsing the interior with water may cause water accumulation, leading to odors and bacterial growth

If you don’t plan to use the machine for an extended period:

1. Empty the water tank.
2. Press and hold the button for 2 seconds to drain the water until the icon disappears.
3. Disconnect the power supply.

When using the machine again:

1. Clean the water tank, fill it with tap water, and plug in the power supply. Wait for it to produce water.
2. Press and hold the button for 2 seconds to drain the water until the icon disappears. It’s recommended to rinse a bucket of water.
3. Follow the “System Use” operation method for normal use.
