A. SPIGOT SWITCH

The SPIGOT switch will automatically  actuate the
auger drive and refrigeration systems when the spigot
is opened to dispense product. When the spigot is
closed, the drive motor and compressor will remain
"on" until the product in the barrel reaches the proper
temperature.

B. OFF-ON SWITCH

The OFF-ON switch is a two position toggle switch
used to supply power to the control circuit. When the
switch is in the OFF position, nothing will run. When
the switch is in the ON position the freezer will be in
the idle mode until a switch is activated.

C. PUSH TO FREEZE SWITCH

The PUSH TO FREEZE switch is a "snap" switch used
to start the freezing cycle. During initial freeze down,
the OFF-ON switch is placed in the ON position. Then
the PUSH TO FREEZE switch is pressed until the
drive motor and compressor come "ON".

NOTE

After the gearmotor starts, there is a 3 second de-
lay before the compressor starts.

During the normal operation, the red PUSH TO FREEZE
switch light will illuminate after the freezer has been
idle for the preset cycles. Before drawing product,
press the PUSH TO FREEZE switch if it is illuminated.
Wait until the green light is illuminated before dispens-
ing.

NOTE

If the freezer shuts off and the PUSH TO FREEZE
light flashes, you have an error condition. Turn the
OFF-ON swtich to the OFF position, correct the
problem and turn the freezer back on. (See Trouble-
shooting.)

D. GREEN LIGHT

The green light is used to indicate that the product has
reached the proper temperature and is ready to be
dispensed.

NOTE

If the PUSH TO FREEZE red light is illuminated,
push the PUSH TO FREEZE switch and wait until
the green light illuminates before dispensing.

E. CLEAN SWITCH

The CLEAN switch is a "snap" switch. When the
switch is pushed the refrigeration system will be OFF
and the auger will rotate for cleaning. When the switch
is pushed again, the auger will stop and the CLEAN
light will flash indicating the freezer is in the CLEAN
mode. To exit the CLEAN mode turn the OFF-ON
switch to the OFF position. If the freezer is left in
CLEAN for more than 30 minutes or is pushed three
times in ten seconds, it will go in error. To reset place
the CLEAN-OFF-ON switch in the ON position and
allow the error light to flash a minimum of 10 minutes.
Then turn to off, wait 5 seconds and turn on.

F. DRIVE MOTOR OVERLOAD

The internal DRIVE MOTOR OVERLOAD will trip if the
drive motor is overloaded. It will reset after approxi-
mately 10-12 minutes. If the drive motor continues to
trip, refer to Troubleshooting (Sec. 4).

G. RED MIX LOW LIGHT

The red MIX LOW light is designed to alert the operator
to a low mix condition. The light will illuminate with
approximately one gallon of mix in the hopper. When
the MIX LOW light is illuminated, refill hopper immedi-
ately.

NOTE

Failure to refill hopper immediately may result in
operational problems.

H. HOLD READY SWITCH

The HOLD READY switch is a push button switch.
When pushed in and held for 5 seconds, the hold ready
mode will be activated. The product will remain ready
to serve and the freezer will not go to idle. To return to
normal operation push and hold for 5 seconds.

I.

DISPENSE RATE ADJUSTER

The dispense rate adjuster limits the opening of the
spigot. To adjust product dispense rate, turn the
adjusting knob clockwise for slower flow and counter-
clockwise for faster flow.

3.3 SANITIZING

Sanitizing must be done after the freezer is cleaned and
just before the hopper is filled with mix. 

Sanitizing the

night before is not effective.

 However, you should

always clean the freezer and parts after using it.

WARNING

THE UNITED STATES DEPARTMENT OF AGRI-
CULTURE AND THE FOOD AND DRUG ADMINIS-
TRATION REQUIRE THAT ALL CLEANING AND
SANITIZING SOLUTIONS USED WITH FOOD
PROCESSING EQUIPMENT BE CERTIFIED FOR
THIS USE.

When sanitizing the freezer, refer to local sanitary regula-
tions for applicable codes and recommended sanitizing
products and procedures. The frequency of sanitizing
must comply with local health regulations. Mix sanitizer
according to manufacturer's instructions to provide a 100
parts per million strength solution. Mix sanitizer in quan-
tities of no less than 2 gallons (7.5 liters) of 120°F water.
Allow sanitizer to contact the surfaces to be sanitized for
5 minutes. Any sanitizer must be used only in accordance
with the manufacturer's instructions.

NOTE

Stoelting, Inc. has found that STERA-SHEEN
GREEN LABEL SANITIZER AND CLEANER does
an effective job of properly sanitizing and cleaning a
soft serve freezer. We therefore include a sample
with each new freezer. Other products may be as
effective. For further information refer to cleaning and
sanitizing information Section 3.13.
