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.
