Query: unsure what the smell is...

Just got my Zo and don't understand why there's a smell of Ozone from it and now spreading throughout the apartment. Did this happen to anyone's first attempt? I thought it might be because it's new?? Unless the machine has been damaged? It did come with a damaged liquid measuring cup that was cracked on the bottom. Can anyone answer me??
