1) Horizontal placement

Air cooler should be placed horizontally, and attention should be paid not to tilt them during use. Before use, check whether the socket 

power supply is consistent with the parameters on the fan nameplate.

2) Frequently adding water

New units or cold and warm air conditioning fans that have been out of use for a long time must be filled with clean water before use. 

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

be unplugged to prevent damage to electrical components. Wait for the water level to slowly rise to near the "highest" position, and do 

not overfill; 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

A typical air conditioning fan is equipped with two ice crystals. Every night, one of them is stored in the refrigerator at home for a period 

of time, and the next day it is taken out and used in the water tank for better results.

4) Proper humidification

If you want to use the refrigeration humidification air supply function, you must first fill the water tank with clean water. 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. Lightly press the cooling and 

humidification button, the indicator light will turn on, and the humidification function will be activated. If the humidification function is 

cancelled, press this button again lightly, the indicator light will turn off, and the humidification function will stop.

5) Swinging air supply

Generally, air cooler has a left and right swing air supply function. When swing air supply is required, simply press the "Wind Direction" 

selection button once to turn on the "Swing Air" indicator light, which will automatically supply air left and right at an angle of 120°. If 

swing air supply is not required, press the Wind Direction selection button again to turn on the "Directional Air" indicator light, and then 

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.
