Beverage air mt 17
There is a fan switch inside the unit beside the light switch, when the compressor is not running you can turn the compressor fan on manually and let it run all the time. Why would you want to do this ,,,, get rid of excess condensate?

See if you can get to their web site. In the operations section, under initial start up, it talks about this. Can't find anything else on this.
Good Luck-Hope this helps.
