Sensordry dual heat tumble drier?

my aunt gave me her old sensordry dual heat tumble drier before emigrating, but never left the instruction manual. I don't know how to use it. My previous drier had a hose attachment to let the moisture out, and I used to have one that collected the water in a container that I had to empty when full, this one only has a vent at the bottom left of the door. where does the moisture go to... HELP!
