7.10 Defrosting
To maintain optimal product quality a frozen drink must be periodically defrosted because ice crystals grow
in size over time and degraded 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. This machine
provides automatic defrosting every three hours if no drinks are dispensed. Dispensing drinks increases the
time between defrost cycles. If additional defrosting is desired, it can be done manually ( see
Section 10.6
). No
defrost time blocks can also be set (see
Section 7.5
).
7.11 Barrels 90% Full on Initial Set-Up
Before beginning a RUN-FREEZE cycle, the barrels should be filled approximately 90% full (up to relief valve
level). If the barrels are above the 90% level, with Fill Off, open the dispensing valve and allow a small amount
of liquid to drain out. If the barrels are not 90% full, press OFF, then FILL, and then slowly pull the relief valve
on the faceplate to vent gas and allow barrel to fill (the screen will display “Filling"). While venting, DO NOT let
the pressure drop more than three to four (3-4) psig.
7.12 Freeze
To freeze the product down, select the barrel by pressing BARREL 1 or BARREL 2 and then press the RUN
button. If the product is liquid, it will take 13 to 15 minutes per barrel (depending on temperature of product) to
complete the initial freeze cycle. Dispense two drinks to condition the barrel.
7.13 Off
There are two options for turning off the dispenser. The first is to turn off one barrel at a time. To turn off, select
the barrel by pressing BARREL 1 or BARREL 2 and then press the OFF button. The second option is to turn off
both barrels at the same time. To do this, press the red STOP ALL button.
