Ⅰ. INTRODUCTION
Thank you for purchasing the Atmospheric Water Generator. The Atmospheric Water Generator is
a new, state-of-the-art water-generating machine, which uses some of the latest and most
sophisticated technology available in the industry today. We have designed your Atmospheric
Water Generator with one objective in mind i.e. to produce the most maximum amount of high
quality drinking water while using only minimum amount of electricity. When hook up with city
water supply, the machine can produce purified drinking water thus makes it a duo-functional
machine.
Ⅱ. SAFETY NOTES
1. The socket should be equipped with reliable protection earthing.
2. Do not remove earthing terminal from the power cord.
3. Do not use extension plug nor extension adaptor.
4. Always keep the unit from poisonous gas and liquid.
5. Do not use damaged electrical plug or power cable.
6. Unplug power cord before maintenance.
7. Do not share the electrical socket with other high power consumption appliance.
8. Always use correct replacement parts.

12. People who suffer from any physical or mental incapacity or lack relevant experience and
knowledge may only operate this product under supervision and guidance of someone who is
responsible for their safety.
13. Keep an eye on children to insure they will not have fun with this produce.
Ⅲ. PRECAUTIONS
1. Do not place the unit too close to the wall. Best performance is obtained when the unit is
placed at least 30 cm from the wall.
2. This unit is not for outdoor use.
3. Avoid prolonged exposure to direct sunlight.
4. Keeps the unit working in standing position.
5. Operating voltage must not drop below 10% of standard Power supply. When the unit
operates below this level, the unit becomes noisy with the possibility of overheating. When
this occurs, immediately switch the unit off until the voltage returns to normal.
6. Avoid prolonged direct eye exposure to ultraviolet device as it may damage the eye.
7. Prevent children playing with HOT knob to avoid scalding.
8. This unit is not suitable for use at places with spray water. Do not
use spray water to clean the unit.
9. To prevent the machine from damage caused by freezing, please
drain off the remaining water and stop operating the machine if the
environment temperature during its working is below 0℃.
10. If there is any damage to the power cables, the cables must be
repaired or replaced by an authorized person to avoid danger.
11. For the condition of operating on uneven ground, a fixer should be

ATMOSPHERIC WATER GENERATOR

mounted to the unit (as pictures).
12. Do not place any object on top of the machine. Good ventilation is required to ensure
optimum performance.
Ⅳ. MAINTENANCE
1. Always keep the unit clean. Wipe the outer casing with soft, damp fabric to clean. Use water
to clean, avoid using harsh cleaning agent.
2. Do not use cleaning agent to clean storage tanks.
3. Clean air filters regularly to ensure proper air flow.
4. When machine not use for a longer period of time, drain out all water completely and clean
all tanks. Please follow sterilization process in the user menu.
Ⅴ. HOW DOES YOUR ATMOSPHERIC WATER GENERATOR WORK?
It is important to be aware that your Atmospheric Water Generator is a humidity and temperature
driven machine. This means the machine totally depends on the level of humidity in the air and the
temperature to produce water. Ideally, the humidity level should be at least 50% or above to
achieve the machine’s optimum performance. In places with lower humidity level, the machine
will still produce water but not as quickly, nor as much as in places with high level of humidity. In
the house environment, higher level of humidity tends to be around the kitchen area, near an open
window or in more spacious rooms. This unit also performs well in an air-conditioned room, but it
is recommended to open the window at night to make the room ventilated.
Because your Atmospheric Water Generator works by converting the humidity in the air to water,

USER’S MANUAL
4
this unit also acts as an effective dehumidifier. In areas with high humidity, It not only acts as a
good water generator, but also a perfect dehumidifier to keep you healthy and ensure your home
appliances a long service time.
To ensure high quality of drinking water, The Atmospheric Water Generator is utilizing multiple
filtration technologies.
When the air is dry or during cold season, water generation will be slow. At this moment,
connection to city water will make the machine serve as water purifier by utilization of the
filtration and sterilization system.
Ⅵ. FEATURES OF ATMOSPHERIC WATER GENERATOR.
1. Microcomputer
The unit is fitted with a microcomputer, which ensures proper working of internal parts.
The machine has preset hot/cold temperature adjustable functions. Temperature of hot or cold
water can preset according to personal preference.
2. Electronic Sensors
Various electronic sensors are attached to parts such as UV light, heating mechanism and
storage tanks. These sensors ensure that all parts are working properly and warn you should a
breakdown or performance irregularities occur in the machine.
3. Energy Saving Features
To conserve electricity, electronic sensors have been placed in the storage tank to automatically
stop the machine from making more water when the tank is full and hot/cold water reaches the

ATMOSPHERIC WATER GENERATOR
5
preset data.
4. Child-proof Hot Water Lock out
The function of hot water lockout is to prevent child from scalding upon touching the water tap.
5. Water Leakage Detector
In case of any unexpected situation of water leakage, the machine can stop working
automatically and accompany with warning sound and flashing screen.
6.Frequency conversion control system of compressor(apply to model with variable
frequency control system Only)
Built-in high performance compressor can operater automatically according to the ambient
temperature and humidity through frequency conversion control system achieving the purpose
of energy saving and noise reducing.
7. Condensing coils
The condenser is designed especially and with food class coating to prevent any metal pollution
and improve water production efficiency.
8. Multi-Stage Filtration System
Our dedication to providing high-quality, great tasting water to our consumers is accomplished
by our unique multi-stage filtration system. It can remove odor and infectant.
8.1. Anti-static patented air-filter:
