Remove the supplies from the vent kit. There will be an exhaust adapter, hose and a window shield with an exhaust opening
Open the window. Place the window shield up to the window. This is a long piece of harder vinyl material that fits in the window from side to side to block bugs and other intruders from getting in while venting the air conditioner. The shield has an exhaust opening at one end. If the shield is too wide, use a scissors to cut it to the width of the Anderson window.
Place the shield in the window and close the window down on top of the shield. This will secure the shield in place.
Connect the exhaust adapter to the exhaust vent on the window shield. Connect the hose to the exhaust adapter. Connect the hose to the back of the air conditioner.
Keep the hose as straight as possible and not coiled up when venting to the outside. If the hose is too long, it can be cut down so that it is not in the way. Turn on the air conditioner.
