1. Prime the Syrup System:
Before trying to brix the machine: Operate each syrup valve (increase flow)
to flush any air or water out of the tubing, pump, or syrup system. This resid
-
ual air and water is left in the system from factory leak testing and machine
setup. If air passes through the syrup valve, syrup cannot, and the drink will
be weak.
a. Place a cup in the cup delivery compartment.
b. Perform a syrup test throw. Refer to "Set Up A Drink" on page 36.
Measure the amount of syrup you get.
c. Repeat step b until 1.7 oz (50 ml) of syrup (the proper amount of syrup
for the 12 oz cup) is dispensed.
d. Repeat steps a through c for all the remaining selections in the machine.
e. Remove and discard the cup.
2. Test for Gas Leaks
Now that the pumps are primed, they will not pulse until syrup is called for.
Test the lines for gas leaks as follows:
a. Close the CO2 cylinder valve.
b. Observe the high pressure gauge. If the reading on the gauge
decreases, there is a leak in the system.
c. Locate the source of the leak and repair it.
3. Purge the Carbonator of Air
BRIX
Is the ratio of syrup to water in a cold drink
machine. Also, to BRIX the machine is to set
up that ratio.
W
hen a merchandiser is first put into service, air may be present in the carbon-
a
tor. This air will not mix with the water, nor will it be absorbed into the water. A
s
p
ressure builds up in the carbonator, the air will be trapped in the top of the car-
b
onator and will prevent
t
he carbonator from filling
w
ith water. The water
p
ump will no longer be able
t
o pump against this high
p
ressure, and it will stop
a
nd display a
d
iagnostic message.
P
urge the carbonator of
a
ny trapped air by lifting up
o
n the pressure relief valve
h
andle as shown. Once
t
his condition is corrected,
i
t will not happen again as long as the merchandiser is properly serviced.
