3.3 PURGING THE CARBONATION SYSTEM
Purge the carbonator tank whenever carbonation issues occur.
A. Turn off CO
2
supply.
B. Turn off power to the dispenser. Unplug the carbonator harness from the power supply.
C. Open the relief valve until water is coming out. Close the relief valve, checking for any remaining
air in the tank.
D. Allow the carbonator tank to fill with plain water by way of the water booster.
E. Once the tank is full, turn the power back on and purge the system by dispensing a carbonated
drink. You should only get plain water as the CO
2
is still off. Dispense several times.
F.
Turn on the CO
2
supply
G. Turn off the power in order to reconnect the pump harness. Turn power back on.
H. Dispense soda at valve until the carbonator pump comes on. Release the button, allow the
carbonator to fill and stop (usually a few seconds). Repeat this process until the water is
carbonated (about five cycles).
I.
Place dispenser back into service.
NOTE:
To check for CO
2
leaks, close the valve on the CO
2
cylinder and observe if the pressure to
the system drops with the cylinder valve closed for five minutes. Open the cylinder valve after
check.
3.4 PURGING THE WATER AND SYRUP SYSTEMS
A. Open a dispensing valve until water and syrup are flowing steadily from the valve. Repeat for
each valve.
B. Check all of the dispenser's syrup and water connections for leaks and repair if necessary.
C. Replace the dispenser's splash plate and cup rest.
3.5 ADJUSTING WATER FLOW AND WATER TO SYRUP RATIO (BRIX)
The water flow can be adjusted between 3.25 oz/sec (96 ml/sec) and 4.50 oz/sec (133 ml/sec) on
all dispensing valves. Ensure ice is on the cold plate for at least one hour before you brix the valves.
The drink temperature should be no higher than 40°F (4.4°C) when the brix is set.
A. Remove merchandiser assembly.
B. If necessary, rotate switches panel forward and down by releasing the two pin latches on its
sides.
C. Rotate light panel, forward and up by releasing the two pin latches on its sides towards the top.
D. Remove nozzle by twisting counterclockwise and pulling down.
E. Install Lancer syrup separator (PN
F.
Activate dispensing valve to fill separator syrup tube.
G. Hold a Lancer brix cup under the syrup separator and dispense water and syrup into cup for four
seconds. Divide number of ounces (ml) of water in cup by four to determine water flow rate per
second.
H. To obtain the proper flow, remove protective cap, and use a screwdriver to adjust water flow
control.
I.
Repeat process for each water valve. There can be up to six gray water valves on the dispenser
(up to four carbonated water valves and two plain water valves).
