6. DISPENSER OPERATION
6.1 Freeze
To freeze the product, press the up or down arrows on the keypad to select the desired barrel, then press the green check
button and select ON. If the product is liquid, it will take four to ten minutes per barrel (depending on temperature of
product) to complete the initial freeze cycle. Dispense drinks until product near faceplate lightens in color indicating the
barrel is properly conditioned.
6.2 Off
There are two options for turning off the dispenser. The first is to turn off one barrel at a time. To turn off individual barrels,
highlight the desired barrel in the home menu, then press the green check button and select OFF. Alternatively all barrels
can be stopped by pressing the red hand button to the left of the screen and then confirming with the green check button.
6.3 Defrost
To maintain optimal drink quality, the product in the barrel must be periodically defrosted because ice crystals grow in size
over time and degrade the consistency and texture of the drink. The best drink quality is always right after defrost and
refreeze. Naturally, it is ideal for the dispenser to be ready to serve drinks at all times, so a balance between defrost and
up time must be maintained. During times of high volume dispensing, a barrel can go longer without defrosting while low
volume periods should defrost every three to four hours.
Most dispensers are configured to execute automatic defrosts to maintain optimal product quality (please refer to Sections
7.13 and 7.14 for directions on setting up defrost times). If a defrost is required outside automatic set times either for
drink quality or service, a manual defrost can be completed by highlighting the desired barrel in the home menu and using
the green check button to select DEFROST. It will take about eight to twelve minutes to defrost (depending on the activity
of the other barrels). Unless the barrel is stopped prior to initiating defrost, it will remain ON and a freeze cycle will begin
after the completion of defrost.
6.4 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 these factors, 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.
There are two settings that can be adjusted for each barrel to change drink quality: the FREEZE ADJUSTMENT, which
controls how frozen the drink is, and the EXPANSION ADJUSTMENT, which controls how much gas is injected into the
product. Both of these adjustments are electronic settings; therefore, no tools are required to make an adjustment. The
type of adjustment will be determined 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 few
drinks to recondition the barrel. Consider the condition of the product in the barrel before making a judgment on the drink
quality.
