Initial Power Up
Plug the dispenser into the power supply and verify by looking at the LCD located behind the merchandiser.
The display should be on the home screen showing the status of the barrels. If the firmware has just been
updated, then the dispenser will prompt the operator to answer the following questions: 1) desired language,
2) number of barrels, and 3) dispenser serial number. After responding to all of the prompted questions the
home screen will then be displayed.
Next, a few verifications will need to be made:
1 Press the green check button and then select the MENU option. Next, select the
READOUTS option.
2 Press the COMMON button.
3 Verify the line voltage is between 200 and 254 volts.
4 Verify the unregulated CO2 pressure is between 70 to 72 PSIG and adjust the regulator if
needed.
5 Verify the water pressure is between 85 to 92 PSIG. This is not adjustable.*
6 Verify the regulated CO2 pressure is approximately 60 PSIG and adjust the regulator if
needed. **
7 Press the BARREL button.
8 Verify the syrup pressures are between 70 and 72 PSIG and adjust the back room regulator
if needed.
Dispense product from the sample valve after adjusting any pressures. This will re-stabilize to the new
pressure.
* The water pressure should be 15 to 20 PSIG above the unregulated CO2 pressure. See the
troubleshooting section if the pressures are not correct.
** The dispenser will tolerate fluctuations in regulated CO2 from 50 to 70 PSIG because it will automatically
compensate. It is best to ensure during setup that it is as close to 60 PSIG as possible.
Brixing
The brix for each barrel must be verified and adjusted for optimal performance. Follow this procedure to
set the brix:
1 Turn the syrup shut off valve to the off position (shown below).
2 Adjust the water flow rate to 1.5 oz/sec (44.4 ml/sec) by dispensing water for 10 seconds
and measuring the volume dispensed. It should be 15 oz (444 ml). Turn the flow control
clockwise to increase the flow and counterclockwise to reduce the flow.
3 Turn the syrup shutoff valve to the on position and dispense a cup of fluid to establish a stable
flow.
4 Dispense a 16 oz sample and measure the sample brix with a refractometer. Be sure to
thoroughly mix the sample first by pouring back and fourth in two cups.
5 Turn the flow control counterclockwise to decrease the brix. Turn the syrup flow control
clockwise to increase the brix.
6 Dispense and discard several samples after adjusting the brix.
The target brix is 13.0 +/- 1.0 for most sugar flavors. Some “light” flavors require a lower brix
