Abstract
Abstract A counter electric beverage dispenser, that can be converted from pressure to gravity operation, and vice versa. The dispenser includes a plurality of dispensing valves, a plurality of syrup tubes, a plurality of water tubes, a plurality of gravity syrup tanks for use during gravity operation, a plurality of syrup inlet pipes for use during pressure operation, and a manifold for each dispensing valve to which is connected a dispensing valve, a water tube and a syrup tube. The dispensing valve is preferably a gravity electric valve that is modified when converting from gravity to pressure operation. A syrup flow control is added to the manifold when converting from gravity to pressure operation. The dispenser also provides an easy method for cleaning out the syrup tubes.
