DISPENSER OPERATION
Operation of the 77X dispenser is simple as many of the operations are automatically taken care of by the
dispenser.
Freeze
To freeze the product down, press the up or down arrows on the keypad until the desired barrel is highlighted
and then press the RUN button. If the product is liquid, it will take 4 to 6 minutes to complete the initial freeze
cycle. You may need to pour a drink or two to condition the barrel.
Off
There are two options for turning off the dispenser. The first is to only turn off one barrel. To turn off, press
the up or down arrows on the keypad until the desired barrel is highlighted and then press the OFF button.
The second option is to turn off all barrels. To do this, press the red octagon button (with picture of a hand)
and then press the green check button to confirm.
Defrost
Sometimes, a barrel needs to be defrosted for service or because the product quality is poor. If you want the
barrel to turn off after the defrost cycle then turn it off before defrosting, otherwise it will return to the run mode
after defrosting. To start the defrost cycle press the up or down arrows on the keypad until the desired barrel
is highlighted and then press the OFF button. It will take about eight to twelve minutes to defrost, depending
on the activity of the other barrels.
Drink Quality
Many factors can affect the quality of a frozen beverage such as time since last defrost, brand of syrup used
and the local water quality. There can even be drink quality differences between the various flavors within
a given brand. Because of this, the dispenser drink quality settings are designed to be easily adjusted to
compensate for these natural differences or even to adjust the drink quality for personal preferences.
To make changes, there are two settings that can be adjusted for each barrel: The “Freeze Adjustment” which
controls how frozen the drink is and the “Carbonation Adjustment” which controls how much CO2 is injected
into the product. Both of these are electronic settings so no tools are required to make an adjustment. The
type of adjustment to make will actually be made based on the drink characteristic that needs to be changed.
Please note that a barrel that has been idle for hours, such as overnight, will produce a wetter heavier drink.
It is best to dispense a drink or two to re-condition the barrel. This fact should be considered before making
a judgment on the drink quality.
Drink Too “Firm” or Cold
A drink that is over-frozen will tend to be very cold, below 22°F (-5.5°C), and can be considered hard and
difficult to suck through a straw. It can also be lighter in weight than a properly frozen drink and tend to
collapse in the cup after being dispensed. To increase the temperature of the drink, increase the setting found
in the FREEZE ADJUSTMENT menu. It will take several compressor cycles before the product in the barrel
has re-conditioned to the new settings.
Drink Too “Sloppy” or Warm
A drink that is not frozen enough will tend to be above 27°F (-2.8°C) and will be considered “wet” or “loose”
and may not stand up in the cup. It can also be heavier in weight than a properly frozen drink. To freeze the
drink harder, lower the setting in the FREEZE ADJUSTMENT menu. It will take several compressor cycles
before the product in the barrel has re-conditioned to the new settings.
