Hello Anonymous, if you are standing behind the appliance, there is a large opening on the left for the "warm air exhaust hose", just above and to the right of this connection is a smaller one, which has a rotating cap that is connected to the air conditioner. Unscrew the cap, take out the black rubber plug (you have to use a bit of force, but be careful that it doesn't break off in the middle, it happened to me) and then put the small hose in, but you have to lead the hose into a (mine is 8 litre) bucket, because when you have the air conditioning in operation, it also dehumidifies the ambient air at the same time. 8-TO NOTE: my experience is not to leave the appliance running unattended for longer than 4-5 hours, otherwise the bucket with the "dehumidifying water" will overflow! Have fun with it and best regards Thelaglar

It is connected on page 12 at no. 7 if it is used as a dehumidifier as mentioned.

Actually only has 1 connection at the back that is suitable for this. However, this is only required if you want to use it as a dehumidifier.
In normal use as an air conditioner, it releases the condensation via the warm exhaust air.
