I. Operation 1. Brewer Overview U The Keurig B3000 Brewer is a commercial single serve coffee brewer specifically designed to be used with the proprietary Keurig K-Cup® portion pack. Coffee beans or ground coffee cannot be processed in this brewer. It can be configured with a coin vend control unit and a platform cabinet for additional K-Cup disposal capacity. It consists of a dual water tank capacity system which allows for fast sequential brewing.
B3000 Brewer Water Flow Mechanisms A schematic and legend showing the major components of the B3000 are provided (refer to page 8 and 9). The functions of these components are listed below. 1. Water filling – The B3000 is a direct plumbed machine. Municipal water is introduced to the unit through the inlet valve [X]. The supply water is then led to the cold water tank [BB] via the rigid plastic tube connected to the float valve [Y].
5. Dispensing Hot Water - To deliver hot water only, the system is closed, vent valve [J] is deenergized, and the hot water dispense valve [OO] is opened. Through a combination of the force of gravity and a pressure boost from the brew pump, water now flows from the lower hot water tank cover thru a silicone tube, the hot water dispense valve [OO], a silicone o-ring, seal cover, and the hot water trough.
