Our units are designed to vent through a window or a wall:
For wall installation:

• The units must be vented on an exterior wall and the air must be driven out of the home.     
• The hot air coming from the unit contains moisture which will produce mold if  vented internally.
• A hole must be cut into the wall leading to the outside similar to a dryer venting system.

For window installation:

• The window bracket sits in the window sill and the hose and nozzle are connected to the bracket and the back of the unit. All the hot moist air is excreted from the unit out through the hose.
