My AC arrived in a new box this week. I set it up last night. The unit shut off after 30 min stating H8 (water full). I drained the water. Started it again and shut off after 15 min. The box did not have the constant drainage hose. Called WESTINGHOUSE and was told should have had a hose and return it. I still wonder why it shuts off so quickly. I will return. I was also disappointed at how noisy it was.
