7. DISPENSER OPERATION
There are a few critical settings that affect drink quality. These settings are preset when you receive the dis
-
penser from the factory. However, due to variations that occur (e.g., in operating environments, syrups, dis-
penser differences, etc.), it may be necessary to make minor adjustments to these critical settings. Adjustments
are easily made using the keypad located behind the merchandiser door at the front of the machine*, or by
adjusting the CO
2
regulator located behind the access panel behind the drip tray.
There are several settings that control product quality:
A. Brix (syrup content of beverage)
B. Expansion
C. Regulated CO
2
injection pressure
D. Freeze and thaw settings
If the drink quality is not as desired, even after the stabilization period, check the critical settings (listed above)
and make the necessary adjustments. The sections that follow provide additional information on these and
other settings.
Note:
On an initial freeze down, products must be given adequate time to stabilize. Adjustments made too
quickly may negatively affect drink quality.
7.1 Brix
To ensure the dispenser produces a quality drink, the syrup content of the drink or brix level must be maintained
between 13.5 and 15. A brix level lower than 13.5 may cause operational problems, produce a weak tasting
drink, and tends to freeze product around the beater shaft. A high brix level (higher than 15.0) causes freeze
down times to be longer and produces a more liquid drink. Water flow rate must be set to provide a flow of 15
ounces in 10 seconds (444ml/10 seconds) prior to adjusting brix (see
Section 6.4
).
7.2 Expansion
The dispenser utilizes a patented liquid level control system to hold a constant liquid level. A constant liquid
level assures a quality frozen product. If a “wetter” product is desired, the numerical setting (0-6) should be
increased. If a “drier” and colder product is desired, the numerical setting should be decreased. The default
setting is 3 and should produce a quality drink.
Note:
Before changing the Expansion settings, check the regulated CO
2
pressures for the dispenser to make
sure they are adjusted properly before adjusting expansion controls.
A drink with not enough CO
2
will be heavy and may look dark in the barrel. A drink with too much CO
2
will be
very light and may even collapse in the cup.
