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 CO
2 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.
When a merchandiser is first put into service, air may be present in the carbon-
ator. This air will not mix with the water, nor will it be absorbed into the water. As
pressure builds up in the carbonator, the air will be trapped in the top of the car-
bonator and will prevent
the carbonator from filling
with water. The water
pump will no longer be able
to pump against this high
pressure, and it will stop
and display a
`^o_=ibsbi
diagnostic message.
Purge the carbonator of
any trapped air by lifting up
on the pressure relief valve
handle as shown. Once
this condition is corrected,
it will not happen again as long as the merchandiser is properly serviced.
