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.
