the purpose of an ac unit is to remove water from the atmosphere so water will be collected and needs to be drained In effect that removal of the water from the atmosphere is what makes you feel cool as you are allowing the skin to perspire more easily

Did you punch out (or cut) the plug that the hose connects to? If not, its blocking the water from draining to the hose. Please rate 4 stars if this is helpful. Thanks and good luck!

Never heard of a metric garden hose connection. Was this unit purchased in the US or overseas? Check box or bag with manual. There may be an adapter in there.
