Is there any requirement for weather and humidity when installing air conditioner?

The requirement for air humidity is very low, and there is almost no requirement.

But it is best not to install air conditioners in rainy days. Because the wall is slippery in rainy days, the operation safety is not good; Moreover, the air conditioner is installed in rainy days, and rainwater can easily enter the connecting pipe of the air conditioner, which will adversely affect the normal use of the air conditioner.
