ABSTRACT:
Purified water is fed into an elevated sealed first tank by means of a float valve assembly. The first tank is vented by a bacteria microscreen which is located above the level of a three-way spigot manifold. A second insulated, sealed hot water tank and a third insulated, sealed cold water tank, both positioned below and fed by the first tank, are vented into the first tank. The second tank is heated by a controlled heat strip or thermoelectric module. The second tank is positioned above and feeds into the third tank, which is cooled by a thermoelectric module. Each of the three tanks is connected by a respective tube into a three-way spigot manifold. An ergonomically designed cabinet in which the three tanks are housed includes a three button spigot control assembly located in a recess approximately 36 inches above the floor. The spigot manifold is positioned in a front panel recess beneath the button recess adjacent to a paper cup dispenser. Airborne and human-carried bacteria and contaminants are prevented from entry into the sealed system.
