Munky, I hear yuh on the confusion! Sorry I don't have the name of the unit I purchased (gave it for my grandchildren last summer's heatwave) but my portable unit went both ways too.
You did not have to necessarily drain the water - but if you do fix it that way be prepared to empty the bucket often. I still don't understand where the water went if you did not hook up the drain hose.
But it MUST be air vented to an exterior exit for the hot air.
I liked it. It had several modes, timer, adjust temperature, etc. Easy to store and move around. Like a lot of appliances it must be a direct line to the plug, regular extension cords won't work with it. Make sure you get the correct size for the room.
