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
monoxide 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
operating 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
through 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.

Before testing the machine, check whether the water level is between the normal range. If
the water level is too high or low, please adjust the float ball. Pull the dust and impu
of the water pipe, check the power supply and if there is any leakage on the water
