Delong's new m3000 air conditioner doesn't drain water, and the refrigeration is OK. The key is to turn off the air conditioner before draining. What is the reason?

This is a normal phenomenon. When the air conditioner is turned on, because the wind speed is too high, there is no drainage, and a small amount of drainage can't be sucked down. If it can't be sucked down, it will be discharged. When the air conditioner is turned off, there is no suction, and all the water comes out at once. If not, it is estimated that there will be a bucket of water at the end of the day, not just the water when parking!
