Carbonator Pump and Motor
Function of the carbonator pump and motor
Increases the pressure of the water, to overcome the CO2 pressure and manufacture/replenish
the carbonated water supply within the carbonator tank.
Failure of the carbonator pump and motor
A weak or defective carbonator pump or motor (key) will cause poor carbonation and limit the
capacity of the unit to manufacture carbonated water.
Must have
250psi(17.2bar) relief
valve setting
Coupling
Clamp
Notes:
w Check water pressure with pumps running (10 psi [0.7 bar] minimum)
w To adjust relief valve setting, dead head to gauge (incoming water pressure + 250 relief
setting)
w Check strainer
w Check for frozen coil in water bath (water to carbonator tank coil)
w Check for power to the motor
w Make sure pump turns freely
To determine the approximate
cycle time:
1. Right after the carbonator kicks
off, draw the carbonated water
into a volume cup until the car-
bonator starts again.
2. Note how many ounces you have
and multiply by 0.28 to determine
how many seconds your cycle time
should be.
(100 GPH pump =
3.56oz/second)
Note: A unit with two 100 GPH pumps
feed the same carbonator tank, mul-
tiply by 0.14
