PORTABLE AIR CONDITIONER - SHARP CV-13NH

SHARP CV-13NH PORTABLE AIR CONDITIONER
I purchased this air-conditioner two years ago while my house air conditioner was broken. I used it for two days and have not used it since. It is in great working condition and has been in a climate controlled environment. I have the original box, remote, and manual paperwork. I paid $800 for it and I`m asking $600 firm.
From the Manufacturer: Sharp`s 13,000 BTU portable air conditioner is easy to move from room to room. It provides both "library quiet" cooling with sleek, attractive styling and a Plasmacluster ion generator. It can also be used as a dehumidifier removing up to 65 pints of moisture in a single day. A full-featured remote control with LCD display allows you to control the unit from anywhere in the room. The flexible exhaust hose and window adapter kit allow venting of hot air while keeping rain and insects out.
