4.6 ADJUSTMENTS (SERVICE PERSONNEL
ONLY)
The following adjustments directly affect product consis-
tency and length of time in "Serve Mode". The default
settings have been created using a 5% milkfat soft serve
mix and provide optimal product consistency while pro-
longing product life.
CutOut (amps)
The CutOut value needs to be adjusted to product
requirements. To properly set the CutOut value,
during startup navigate to the "°F" and "amps"
values under the Display menu (Refer to Section
2.3), start the machine and freeze the product to
the desired consistency. Monitor consistency by
taking a 6-8 ounce sample at each change of the
"amps" display. When the desired consistency
has been reached, record the temperature and
amps, and change the CutOut value to the
recorded amps value.
Cut In T (°F)
After the consistency value has been determined,
the Cut In T value can be adjusted. This value
along with the CutOut value determines the range
of temperatures (or "temperature window") of the
product. Decreasing the temperature decreases
the temperature window and shortens the length
of freezing cycles. This creates a greater chance
of product breakdown by stirring the product
often. Increasing the Cut In T increases the
temperature window which decreases freezing
cycles and increases the chance of heat shock
within the product.
Cycles (count)
This setting determines the number of freezing
cycles during "Serve Mode". Increasing the value
will increase the total time in "Serve Mode". Factory
default is 20 cycles. This results in "Serve Mode"
lasting between 45 minutes and 2-1/2 hours without
the PUSH TO FREEZE button being pressed or a
spigot handle being pulled. If the PUSH TO
FREEZE button is pressed or the spigot handle is
pulled at any time during "Serve Mode", the Cycles
count will reset.
4.7 OTHER SETTINGS (SERVICE PERSONNEL
ONLY)
Changing any setting on the IntelliTec control will alter
machine operation and affect the product temperature,
consistency, or life. Refer to the IntelliTec Control System
Settings sheet located in the information pouch behind the
right panel of the machine. If any of the following settings
on the IntelliTec control differ from the System Settings
sheet, it is recommended to revert those settings to factory
defaults.
Refriger
The options available for this setting are None, 1
Hopper, 2 Hopper, and Cabinet. Changing this
setting changes how the control handles the
storage refrigeration cycle. The left control must
always be set to Cabinet and the right control must
be set to None.
CabCutIn (°F)
If the Refriger value is set to Cabinet, this setting
determines the temperature at which the
refrigeration cycle starts. If None, 1 Hopper, or 2
Hopper is selected for the Refriger setting,
CabCutIn will not be shown on the IntelliTec
menu.
CabCtOut (°F)
If the Refriger value is set to Cabinet, this setting
determines the temperature at which the
refrigeration cycle stops. If None, 1 Hopper, or 2
Hopper is selected for the Refriger setting,
CabCtOut will not be shown on the IntelliTec
menu.
4.8 OVERRUN ADJUSTMENT
The product, when served, is a combination of air and mix.
Overrun is a measure of the amount of air blended into the
mix.
Overrun can be expressed in terms of the amount of
weight loss for a given volume. For example, if a pint of
liquid mix weighs 18 ounces and a pint of frozen product
with air added weighs 12 ounces, the overrun is said to be
50 percent: 18 oz. - 12 oz. = 6 oz., (6/12) x 100 = 50%
The overrun can be checked by placing a one pint con-
tainer on an ice cream scale and zeroing out the scale.
Then fill a one pint container with frozen product. The
container should be filled over the top and leveled with a
straightedge. The product should not contain any air
pockets. When weighed on an ice cream scale, one pint
of product should weigh 12 to 13 ounces.
The mix pump has been preset at the factory to produce
a product with approximately 40% overrun. Because of
differences in mix formulation, temperatures and baro-
metric pressure, this figure may vary. It will be necessary
for approximately 2 gallons of mix to be pumped through
the machine before overrun changes in the product are
noticeable.
Overrun is controlled by the length of the air compressor
piston stroke within the piston cylinder. Lengthening the
stroke within the cylinder will increase overrun. Con-
versely, shortening the stroke will decrease overrun. To
perform an overrun adjustment, refer to the following
procedure:
