Carbonator Pump on
When the carbonated water level in the carbonator tank falls below both the electrodes, the
liquid level control will send electricity to the carbonator motor. The motor turns the carbonator
pump, which increases the water pressure from 55 psig (3.8 bar) to approximately 140 to 170 psig
(10 to 12 bar). This boosted water goes through the cooling coil in the water bath, through the
double check valve and overcomes the 90 psig (6.3 bar) CO
2 pressure within the carbonator tank.
Water flowing through the orifice at the base of the check valve is broken into tiny droplets and
sprayed into the carbonator tank, absorbing CO
2 to produce cold, quality carbonated water.
While the motor and pump is running, the carbonated water level in the tank will rise until it
reaches the low and then the high electrode, at which point the liquid level control will shut off
the electricity to the motor. Each time a sufficient amount of carbonated water is drawn from the
carbonation tank, the cycle will repeat.
