THEORY OF OPERATION
A carbonator is a device designed to dissolve carbon dioxide gas (CO2) in water, producing carbonated water.
CO2 gas is delivered through a regulator to the carbonator tank. Simultaneously, plain water is pumped into
the tank. The CO
2 gas, under pressure, dissolves in the water and the result is carbonated water. When the
level of carbonated water reaches a pre-determined point, the liquid level sensing device (inside the tank)
signals the liquid level control module which, in turn, shuts off the pump motor. As carbonated water is drawn
from the tank, the level of carbonated water will drop. At a certain point, the liquid level sensing device
recognizes that drop in the level and turns on the pump motor which replenishes the amount of carbonated
water that has been taken out of the tank.
