SAKURA – Total Air Conditioning Solution

Please read this instruction carefully before using

PAGE

1.Do not put your hand or other stuff in the air outlet of the operatin machine.Otherwise,it may cause injury.

2.Do

not place heavy object on the unit,keep child away from the unit

3.Do

not put gas cooker in the place which the unit can blow directly. Otherwise,it may cause carbon

monoxi

de poisoning.

4.Do

not disassemble or modify the unit since the wrong operation may cause water leakage,fire or electric

shock

.

5.Do

add water from the water inlet of the unit

6.Do

not install the unit in the place full of explosive and flammable materials.

7.When

not using the unit for a long time,please drain the water tank of all the water.Then keep the unit

ope

rating in fan mode for 10 minutes to dry the cooling pad,then turn off the power switch.

8.Always

ensure effective earthing.

The

environment friendly air conditioner has following advantages:

Power

saving:it can save over 80% compared with traditional air conditioner Environment friendly:No

harmful

material,no freon during operating. High Efficiency:Use the min.power to make the max cooling

and

purifing effect. Working Principle:The evaporative air cooler produces effective cooling by combining a

natural

process-water evaporation-with a simple,reliable air-moving system.Fresh outside air is filtered

throu

gh the saturated evaporative media cooled by evaporation,and circulated by a blower wheel. Water

from

the bottom pan of the unit is pumped to the top and allowed to flow down over the evaporation cooling

pads of the spot cooler,evenly saturating the pads. Then a powerful blower pulls air through the

pads,forcing the water to evaporate which decrease the ambient temp.The cool air is then blown by the unit

at

a high velocity where you direct the cool air to go.
