impreston - with out the following parts , you really don't have "just the air conditioner."
1- Flexible Exhaust Hose
2- Hose Adapters
1- Sliding Window Kit
1-Foam Window Seal
The drain hose is something you supply. A garden hose, no longer than 5 feet will do if you want it to be a continusos drain, rather than drain into the water collectiong bucket. But, without the first 4 items lister above, you won't be able to operate the unit.
