Unit did not work once it was installed.  I uninstalled it and found that the cover over one end of the cage wheel was hard against the cage wheel. Once I removed the cage wheel cover......I found that the cage that holds the fan wheel was also bent into the fan.  I had already burned the boxes thinking I wouldn't have any issues......I was wrong.  This was not put together well at all and if I wasn't pressed for time.....I would have sent it back and wanted a refund. I got it working but would not buy another from this company
