ABSTRACT:
A post-mix beverage dispensing system including a cabinet having top, front, back side and bottom panels for housing various components. The components include a carbonator for producing carbonated water by mixing cooled potable water with CO.sub.2. Potable water is stored in a portable tank and is supplied to the carbonator through a first pipe. A cooling reservoir contains cooled water, and a serpentine section of the first pipe, along with the carbonator, are disposed in the cooling reservoir. A CO.sub.2 tank supplies CO.sub.2 to the carbonator and syrup packages. The flow rate of syrup from the syrup packages is kept constant by the pressure of CO.sub.2 from the CO.sub.2 tank. The front panel has a permanent magnet thereon, and the top panel has a reed switch thereon such that the permanent magnet is adjacent to the reed switch when the front panel is disposed on the cabinet. When an empty package is to be replaced with a new one and the front panel is opened, the reed switch is turned off, since the permanent magnet is spaced from the reed switch. An electromagnetic valve is thus cut off, and the supply of CO.sub.2 from the CO.sub.2 tank to the syrup packages is thereby stopped. The CO.sub.2 is thus automatically prevented from venting to the atmosphere when the front panel is opened.
