In automatic load units, ice is manufactured in either one or two Follett remote icemakers. These icemakers may be located up to 20 f. (6m) away from the dispenser. As water freezes to the inside walls of the icemaker evaporator, a rotating stainless steel auger removes ice and carries it to the top of the evaporator assembly where it is compressed and extruded through an outlet port. - Page 10 Cleaning and sanitizing beverage system before use Cleaning Prepare 6 gallons (23 liters) of cleaning Solution A. Fill a clean product tank with cleaning solution. Fill a second clean product tank with potable rinse water. Disconnect all syrup lines from product containers.
