Query: Kenwood air conditioner

I bought this unit as an open box buy. It cools off 4 rooms wonderfully. I was happy to be able to download the manual off of amazon's website.I have not been happy with Kenwood's customer service. I had contacted Kenwood several times via email in order to order parts that were missing (because I bought it as an open box item) and to receive a manual but had no success. My husband ended up making the window accessory that was missing and I ended up downloading the manual from amazon.com.Thanks guys!The portable air conditioner was definitely worth my money.
