UPDATE: The refurbished unit was supplied with the wrong remote. It says “Chauvet” at the top with no model number. The new remote that works says “Chauvet DJ”. I called Chauvet and asked them. they also said Froggy’s Freezin Fog juice is thick so clean out your machine after every major use so it doesn’t clog the lines. the popular home made cleaning solution mixture of distilled water and distilled vinegar is fine. after cleaning take the tube out and run it for 5 seconds to pump the mixture out. run the machine once a month with distilled water or fog for 5 minutes if not used very often so the pump does not seize.
