In summer, with hot and humid weather, both the office and home cannot be without air cooler. There are many benefits to 

using air cooler, but how to use, store, and clean it most reasonably and scientifically? Here are a few tips for you:

     1. Horizontal Placement

     The air cooler should be placed horizontally and not tilted. Before use, check whether the socket power supply is consistent 

with the parameters on the fan nameplate.

     2. Frequent Addition Of  Water

     For new units or air cooler that have been out of use for a long time, they must be filled with clean water before use. The 

water level can be observed through a water level gauge to control the amount of water added. Before adding water, the power 

plug should be unplugged to prevent damage to electrical components. The water level to be filled should rise to near the 

"highest" position, and should not be too full; After filling the water, close the door and pay attention to the water level when

using it for refrigeration. When the water level drops to near the "lowest" position, it should be replenished with water, otherwise

the refrigeration effect will be lost.

     3. Frozen Ice Crystals

     Generally, air coolers are equipped with two ice crystals. Every night, put one of them in the refrigerator at home for a period of 

time to refrigerate, and the next day take it out and use it in the water tank for better results.

     4. Proper Humidification

     To use refrigeration and humidification for air supply, it is necessary to first add clean water to the water tank. After about 1-3 

minutes of operation, the outlet temperature will decrease from the ambient temperature and achieve the best effect. When 

conditions permit, add low-temperature cold water or ice water for better cooling effect. If an appropriate amount of spices are 

added to water,  the resulting breeze will be fragrant and cool, making people feel relaxed and comfortable in the hot summer.

     5. Swinging Air Supply

     Generally, air coolers have a left and right swinging air supply function. When swinging air supply is needed, simply press the 

"Wind Direction" selection button once to turn on the "Swinging Air" indicator light, that is, immediately automatically supply air 

left and right, with a supply angle of 120 degrees. If swinging air supply is not needed, press the Wind Direction selection button 

again to turn on the "Directional Air" indicator light, and stop swinging directional air supply. At the same time, the upper and lower

air supply positions can also be adjusted. For example, adjusting the direction of the long air guide by hand can make the air supply 

direction all downward or upward, and adjust it to the most ideal position according to your needs.

     If the air cooler is not used for a long time, the water in the water tank should be cleaned thoroughly, and air should be supplied 

at room temperature for a period of time to completely dry the inside of the machine, especially the filter screen, and then covered 

with plastic bags for reuse.
