V. Working principle of the product
The atmospheric water generator gets water by the drive of air humidity and air temperature, i.e. it means the total water quantity
the product takes depends on air humidity and temperature. The best performance of the product can be achieved in the ideal
condition when air humidity is at least over 70%. The product can also take water but with water taking speed decreased in areas
with lower humidity levels. In family environment, the product is generally placed around the kitchen, under the open window and
in the comparatively large room. Also, the product works in rooms with air-conditions, but we suggest that the windows shall be
open for ventilation at night.
Since the atmospheric water generator converts the water vapor in the air into water, the product can also be used as the
dehumidifier. The product can be used as not only the atmospheric water generator but the dehumidifier in areas with
comparatively high humidity, which guarantees the users' fitness and longer service life for other household appliances.
The product adopts the multiple-air filtering technology for high quality.
The water producing speed will drop suddenly in the cold and dry season.
VI. Product characteristics
a. Microcomputer board control: This product adopts the microcomputer board control which can guarantee the stable working of
all the internal components and the working conditions of each component inside the machine.
b. Electronic sensor: Each component of the product is accompanied by various kinds of sensors, such as: UV light, heating
apparatus sensors, humidity sensors and ice water sensors. These sensors can ensure that each component inside the product
works coordinately, and can give an alarm automatically when some components fail.
c. Energy conservation: The electronic sensor is installed in the water tank to save electric power. The product will stop producing
water automatically when the sensor induces that the water tank is full, and will stop heating or refrigeration automatically when
the cold water or hot water reaches the set temperature.
d. Child safety lock: The function can prevent children from burns resulting from touching the hot water tap.
e. Water leakage detector: The machine will stop working automatically and make a sound warning and simultaneously cut off the
power supply under the condition that the water leakage happens.
f. Condensing coil: Adopt the spray finishing of food grade to prevent metallic pollution and improve the working efficiency of
water production.
g. Filter screen: The first layer filter screen is used after air is condensed and converted into water. This filter screen can prevent
effectively harmful bacteria, dust, silt and other floaters from entering the machine.
h. Ultraviolet sterilization treatment: There are special ultraviolet germicidal lamps in the machine to guarantee all the
microorganisms and bacteria in the water can be eliminated. The sterilization process is controlled by the microcomputer

4/9
automatically.
i. Ozone germicidal treatment: The machine possesses special ozone germicidal treatment which can eliminate the bacteria in
raw water and circulating water.
j. Water circulation system: Disinfect the storage water periodically and carry out the RO filtration treatment again to ensure the
bacteria free water.
k. Multistage filtration system: The four-stage filtration system helps our product provide consumers with the drinking water with
high quality and terrific taste.
1) PP fiber filter element: Eliminate suspended solids and silt and other granular impurities.
2) Granular active carbon: With high adsorptive capacity, it can eliminate organics and residual chlorine with abnormal color and
taste and so on.
3) Precise active carbon: Eliminate organic compounds, chlorides, heavy metals and so on.
4) Reverse osmosis RO membrane: Eliminate dangerous bacteria, virus, mineral salts, heavy metals and organic compounds
and so on.
VII. Instructions for use
Used according to the following operation guides and simple maintenance procedures, the machine can work with no faults and
produce the maximum pure drinking water with high quality. Please read carefully the instruction before the product is used, and
you will be very familiar with all the functions of the product after looking through the instruction carefully, which can ensure the
correct use of the machine.
