To users
Dear users:
First of all, thank you for choosing and using our air cooler. Before using our
product, please read this manual carefully. For the safety of you and your
family, be sure to follow the instructions in this manual.
Working principle
The draught fan does a suction to make a subpressure, at the same time the
pump carries the water to the distribution instrument to make the wet curtain
moist.
The hot air passes through the wet curtain, and the heat is absorbed by the
evaporating water, then the temperature comes down. The cool air is blown
out by the fan. The unevaporated water would drop to the water tank and
form a circulation.
Please open the window and the door when you are using this machine.
To keep fresh air circulating smoothly, the best way is to place it in front of
the ventilation corridors.
