FUNCTIONS
●Heat: Heated by PTC heating unit, which has highly efficient conversion between electricity
and heat, and rapid heating.
●Cooling: this is achieved by a honeycomb filter design that provides maximum surface area and
optimizes cooling performance. Air is forced to come in contact with evaporating water which
provides maximum cooling effect. This is a powerful motor which is designed to deliver
maximum airflow with minimum noise.
●Anion: Air purification through Ionization of charged particles.
●Adjustable speed: the unit has three speeds for Cooling and 2 speeds for heating.
●Modes: Normal, Natural and Sleep. In normal mode the unit delivers constant air at a selected
speed. Natural Mode provides variable airflow similar to that blows in forests. Sleep mode is
working with soft wind.
●SWING : This provides horizontal movement of air, to cover wide area for heating or cooling
by movement of front louver vents. The air direction can also be adjusted vertically and
downwards by adjusting internal louver vents mechanically by hand.
●Remote control: 6 meters range remote control. Requires 2 X AAA
ASSEMBLING AND PREPARATION
1. Place the appliance on a flat surface, with the help of small spanner (provided) take out the
assemble the castors at the base in the four holes provided. Castors come with self tapping screw
and will screw into the holes with a small amount of force with spanner.
Note: The back castors come with brake, and the front ones do not have brakes. (map 1)
2. Water: Pull out half of the water tank at the back, add approx. 4 litres of water.(map 2)
Attention:
a. Pay attention to the level of water tank when adding water.(map 3)
b. The level of water tank should not over “MAX” scale at any time, and total level of water
tank should not below “MIN” scale. Minimum level takes approx. 3 litre and maximum up
to 6 litres of water.
c. You can put Ice cubes or pre chilled ice bottles directly into the water tank if you want to
cooler air. However the total level of water tank should not be over “MAX” scale.

OPERATION
●ON/OFF: Turn on the power switch at the side of unit a short bleep is heard, the unit is ready to
use. Pressing ON/OFF key, once will start the operation and a second press will turn it off.
●Speed: Heater has two speeds and cooler has three speeds.
● Cooling: Press ON/OFF key on the control pane, press speed and select the speed you would
like.
Press COOL key, if the tank does not have enough water you will hear a continues bleep Put
water Above the minimum level.
●Heating: Press ON/OFF key, press speed and select the speed you would like. Press HEAT, one
press of Heat key is heat level 1 which is 1000 Watts, two presses of HEAT key will provide
level II of HEAT which is 2000 Watts.
●Mode: By pressing this key you can select normal constant airflow, or natural wind by selecting
the symbol of the tree or sleeping mode to provide wind with circular motion.
●Swing: Press this key, the airflow will start moving horizontally. Pressing this key again cancels
the program.
●Anion: Air purification key: one of the best ways to purify room or a house is by ionization or
a process in in which anion is produced which is a negatively charged ion or particle, which then
attract all positively charged particle and purify the vicinity.
●Timer: 12 hours timer, each press adds 1 hour.
THE USE OF REMOTE CONTROL
The remote control has the same functions as the control panel. Aim the remote control within 6
metres towards the unit and press desired operation. When the remote control is not in use, please
put away it for using next time.
Attention:
a. Do not mix old battery with the new one in use.
b. Please remove the batteries if the unit will not be used for a long time.
THE USE OF ICE-CRYSTAL BOX
The ice-crystal box has a particular feature of keeping cool, it can absorb heat and let the water
temperature below the environmental temperature.
Using methods：
a. Put the ice-crystal boxes into the refrigerator to make sure that they iced absolutely.
b. Draw the water tank, then put a frozen ice-crystal box into it. And push the water tank into to the
unit.
c. There have two ice-crystal boxes, so can use circularly.
