GENERAL INFORMATION
SYSTEM OVERVIEW
The Automated Beverage System ABS 2.0 is an upgraded version of ABS. The ABS 2.0 is designed for
drive-through area installation or other restricted area that is accessible to authorized personnel only. When a bever-
age is ordered from the P.O.S. register, the ABS 2.0 automatically drops a cup, fills it with ice and dispenses the cor-
rect amount and type of any syrup-based beverage. The finished drink is then moved by the conveyor to the pick-up
station and the drink description is displayed on the touchscreen.
Operation of the ABS 2.0 is restricted to employees and service personnel that have been trained and certified
in the proper operation, service and maintenance of the equipment.
