Questions about Wood's AC Milan 7K Smart Home

How loud is this device in your house? I bought it because it is supposed to be very quiet at 51dB. As long as only the ventilation is running, it is relatively quiet. But as soon as the cooling switches on and the warm air is blown outside, it is very, very loud. Like a hoover or hair dryer. My mobile app, which is certainly not very accurate, says 65-70dB. Have I got a piece of equipment that doesn't work?

How often do you have to empty the tank with the condensed water at the bottom or top and is there a possibility to buy a hose to connect it? I find it very difficult even with that as the 2nd drain button is very far down. Also, I can't connect the unit to the app, despite resetting the cooler.

The air coming out isn't very cold at all. I've got it on the cool mode and full fan with the pipe going outside, with the temperature set to it's lowest. Anyone else having this same problem?

How can I reset the device? or better asked which is the reset button I have tried everything but unfortunately I cannot reset the device.

What window kit does it come with?
