SU412 Model Machines
Off Time (sec)
Increasing this value will increase the time between
freezing cycles in “Standby Mode” and result in
an increase of product temperature in the barrel.
Stb Time (sec)
This setting determines the total amount of time
in “Standby Mode”.
Sl1DrvOn (sec)
Adjustments to this setting affect the amount of
time the auger rotates in the stir cycle. This stir
cycle only occurs in “Sleep 1 Mode”.
Sl1DrOff (sec)
Adjustments to this setting affect the time between
stir cycles. The stir cycle only occurs in “Sleep 1
Mode”.
Sl2CutIn (°F)
Changing this setting affects the temperature at
which the freezing cycle starts in “Sleep 2 Mode”.
Sl2CtOut (°F)
Changing this setting affects the temperature at
which the freezing cycle stops in “Sleep 2 Mode”.
DftOffTm (sec)
In “Serve Mode”, this value determines the
maximum time without a freezing cycle. If this
value is met, a freezing cycle will start. In the event
of a freezing cylinder temperature sensor failure,
this value affects the amount of time between
freezing cycles during “Serve Mode”.
Refriger
This setting changes how the control handles
the storage refrigeration cycle. The setting for
the SU412 is Cabinet.
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.
Cab Off
If the Refriger value is set to Cabinet and the
temperature sensor in the cabinet fails, this setting
determines the time between refrigeration cycles.
If None, 1 Hopper, or 2 Hopper is selected for the
Refriger setting, Cab Off will not be shown on the
IntelliTec™ menu.
Cab On
If the Refriger value is set to Cabinet and the
temperature sensor in the cabinet fails, this setting
determines the length of the refrigeration cycle. If
None, 1 Hopper, or 2 Hopper is selected for the
Refriger setting, Cab On 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 fi ll a one pint container with frozen product. The
container should be fi lled 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 fi gure may vary. It will be necessary
for approximately 2 gallons of mix to be pumped through
the freezer 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. Conversely,
shortening the stroke will decrease overrun. To perform
WARNING
Hazardous voltage
The Main Freezer Power switch must be placed in
the OFF position when disassembling for servicing.
The freezer must be disconnected from electrical
supply before removing any access panel. Failure
to disconnect power before servicing could result
in death or serious injury.
