I have just purchased this unit ( lg air conditioner 6000 btu and so frustrated! This This air conditioner doesn’t deserve to carry lg’s logo . unit cannot even cool down a 200 sqft room! 
Too noisy and loud! No water detaining hole in the unit’s  back despite showing in website’s photos! Here in Montreal we don’t have too many hot days by the way you need an ac in the summer time. When I purchased this unit the weather was nice and  after installation I was waiting to see how it performs in  warm days... it made me so disappointed when the weather temperature raised to 32 degrees C! Not capable to do at least a desirable change! Unit was running whole day and temperature  not comfortable just noise...
I could not stay in the  room!
I have been always a lg fan and consumer. I don’t forget I stayed  such a long  time in the line up to get the new released lg g2. I recommend lg to everyone I knew. But, now I feel bad and don’t know how to do with this unit?
