General Safety Precautions
1. Always switch off and unplug the appliance from the electrical
outlet BEFORE cleaning and also when not in use.
2. When adding water, do not fill water above “MAX” level.
3. Choose normal wind when environmental humidity is high as
cooling function is accompanied with humidity.
4. After adding water into the water tank, keep the appliance at
upright position when placing or moving to prevent water from
overflowing.
5. Do not put any objects on the appliance.
6. Disconnect power and pull out the plug before cleaning and
repairing.
7. Clean the outside of the appliance with wet cloth (or add some
detergent). Do not use corrosive detergent or solvent to clean.
Pouring water on the appliance is strictly forbidden.
8. If the appliance falls down with water in it, pull out the plug from
the electrical outlet immediately. The appliance can be
switched on after 24 hours of drying. Damages may occur on
the appliance if this instruction is not followed.
9. Do not position the wind outlet and wind inlet of the appliance
close to wall or curtain; otherwise air delivery can be blocked.
10. After using for a certain period of time, the appliance may emit
noises and the wind volume becomes uneven. This is caused
by dust accumulating on the air filtering net and blocking the
airflow. Cleaning the air filtering net solves this problem.
11. When not using the appliance, pull the plug out of the electrical
outlet.

12. The appliance must be taken to the appointed service centre
for repairing.
13. This appliance should not be used by people who are
physically or mentally impaired (including children) unless
proper guidance is provided during operation.
14. If the power cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons in
order to avoid hazards.

How to assemble
Open the package and take the appliance out. Connect to the
electrical outlet after removing the foam cover.
Open the water tank cover on the lower back of the appliance
and add water into the water tank (Figure 1). Observe the
water level through the watermark to control the water amount
(Figure 2).
Pay attention to the following
When adding water, pay attention to the water level indicator at
the front of the appliance.
Do not over fill water above the red water level line.
Close the cover when finished adding water, otherwise the
appliance will not work.
If you want to reduce more temperature, you can add ice into
the water tank.
Instruction of “ICE PACK”
The appliance is packaged with two unique “ice packs”. The ice
packs are specially used for keeping cool. It can absorb the
energy of water little by little, keeping the temperature of the
water at around 180C, lower than that of the ambience. This
makes the wind cooler.
Operation Method
Put the ICE PACKS into the refrigerator and keep them inside
until they are completely frozen.
Put one ice pack into the water tank. Close the cover. The
temperature of the water will be 80C lower than that of the
ambience and this will be maintained for 4 hours, making the
wind cooler.
The two ICE PACKS can be re-used continuously.
On/Off Key
“ON/OFF” key is used for starting and stopping the appliance.
Wind speed starts from medium speed and will change to low
speed 3 seconds later.

Speed Key
Press this key to change the wind speed. The LED will show the
wind speed accordingly.
Cooling/Humidity or Water Key
Press this key when adding water or ice. Outlet temperature will be
lower after 20 seconds later and the indicator light will be turned on.
Oscillation Key
Press this key and louver will swing from one side to another.
Timer
Timer can be selected between 1-9 hours.
Ion Key
Press this key and the built-in anion generator will start to release
anion. Indicator light will be turned on.
Mode Key
Press this key to select the type of rotation mode. The modes
available are “Normal Wind”, “Natural Wind” and “Sleeping Wind”.
Normal Wind
Constant rotation with different wind speed of High, Medium and
Low as set.
Natural Wind
The fan operates in High, Medium and Low speed in a circle as
preset by microcomputer program for 90 seconds per circle and 6
seconds for each section (pause for 3 seconds). High, medium or
low wind can be generated by using together with Wind Speed key
that imitates the natural breeze with gentleness and comfort.
Sleeping Wind
In this mode, the appliance will be under computer-controlled
normal wind mode. The speed will be lowered down gradually
according to the change of human body temperature, eliminating
the risk of getting cold during sleeping. The lowering procedure is
as follows:

Care and Cleaning
Air Filtering Net
Pull out the power plug and hold the handle of the air filtering
net to pull out the air filtering net. (If the environment is
susceptible to dirt and dust, wash it once in every one or two
months and replace with fresh water every two months.)
Cleaning method
Wash the net with mild soap water and soft brush. After that,
put the net to dry under the sun for at least 4 hours before
mounting it back to the appliance.
Clean the water tank once a month for best performance and
hygiene purpose.
Disconnect the power and discharge the water in the water
tank. Open the water tank cover and clean the sediments and
