INSTALLATION BEFORE USE
1) Exhaust Duct
When you use the unit as an air conditioner or a dehumidifier, the fresh outdoor air must
be directed to the unit and the hot air must be exhausted out of the room to complete the air
exchange. When the unit is operating on fan or heating models, no outdoor air exchange
takes place. You do not need to hookup the window kits and exhaust hose when you use the
unit as a fan or a heater.
a) Pull out of both ends of the exhaust ducts for approximately 6”.
b) Screw clockwise the exhaust ducts with one end to the terminal end and other end
to the window kit adapter.
c) Remove exhaust outlet wall covers from the back of the unit by screwing the covers
counter-clockwise before lifting them up.

d) Mount terminal ends of the exhaust hoses to the unit.
e) Open window or sliding door for approximately 5 inches (130 mm)
f) Adjust the length of the window kit to the same length of the window or the sliding
door. Use all three panels if necessary. Cut the window piece as needed to fit the
length of your window or sliding door. Make sure that both holes on the main piece
