SANITIZING & OPERATION

Prior to proceeding, make sure that the carburetor
tube holes are clean and free of old product debris
or lubricant. A blocked carburetor tube will cause
incorrect product consistency and/or damage the
machine if product should freeze too thick.
4. Once mix pan is at least one-half full, and bubbling
has ceased, install the carburetor tube into the hole in
the mix pan with a gentle twisting motion.
5. Move the control switch to the “AUTO” position
and the unit will start in 3-5 seconds.
6. Allow the compressor to cycle 3-4 times dispensing
a sample of the product after each cycle to check for
consistency. If the machine is not dispensing the
product at the desired consistency after four full cycles,
refer to the Consistency Control Section of this manual.
Initial pull-down time is 10-15 minutes, but may vary
due to product mix and ambient conditions.
8. Replace the mix pan lid and always operate the
machine with the lid on the mix pan reservoir.
There must be product in the mix pan for machine
to start.
NOTE: WHEN REFILLING THE MIX PAN DURING
DAILY OPERATION, DO NOT POUR SHAKE OR
SOFT SERVE MIX DIRECTLY ONTO THE MIX PAN
AGITATOR.
If the agitator stops turning during machine operation,
a. turn off the machine
b. reposition the agitator with a sanitized utensil - see
sanitizing instructions for sanitizing procedure
c. follow the instructions for starting the machine.

HELPFUL HINTS
PAGE 11
Front Plate: This component is the plastic device from
which the product is dispensed. It is designed and
manufactured for strength and durability. However,
through improper use, the front plate can be damaged.
Use the following information for proper care:
a. Do not over tighten the knobs.
b. Always tighten knobs evenly. Do not attempt to
turn one knob all the way down and then one of
the other three knobs. Doing so will bind the front
plate and could result in breakage.
c. Improper installation of the stator rods can cause
breakage. The stator rods must be properly
seated in the dasher before installing the front
plate. If the stator rods are improperly installed,
subsequent tightening of the knobs will break the
front plate.
d. DO NOT attempt to wash the front plate or any
other components in a dishwasher.
Mix Out Light: When the mix out light comes on, the
mix pan is low on mix. The mix pan must be filled with
fresh product mix immediately to prevent air from
entering the freezing cylinder starving the machine and
causing freeze-up and vibration. If this condition occurs,
set the selector switch to the “OFF” position. Remove
the carburetor tube and add mix to the low mix pan until
the freezing cylinder stops bubbling. Replace the
carburetor tube with a gentle twist, then return the
control switch to the “AUTO” position.
Filling: Always fill the machine with fresh product at the
start of each day.
Drip Tray: This should be removed daily and cleaned
to remove residue.
Mix Pan Lid: Be certain to leave the lid in place on top
of the machine to prevent any foreign materials from
contaminating the mix.
Mixing: Make certain that the product mix is prepared
according to label instructions.
Sanitizing: Do not soak plastic parts in sanitizer
overnight. Doing so can cause the plastic parts to
become brittle and lead to premature failure.
Mix Pan Agitator: If the mix pan agitator stops turning
during operation of the machine, turn off the machine,
reposition the agitator with a sanitized utensil, and
follow the instructions for starting the machine.
DO NOT POUR PRODUCT MIX DIRECTLY ONTO
THE AGITATOR WHEN YOU FILL THE MACHINE.
Treat the mix pan agitators as any other small parts
such as the scraper blades. Follow the same cleaning
and sanitizing instructions.
Winter Storage: To protect the unit during seasonal
shut-down, it is important that the dispenser be stored
in the proper manner. Use the following procedures:
1. Turn off ALL power to the machine.
2. Wash all parts that come in contact with the mix
with a warm mild detergent solution. Rinse in clear
water and dry parts thoroughly.
3. Store the loose parts such as the mix pan
components, front plate parts, and the dasher
assembly parts outside of the machine.
4. Do not lay heavy objects on the plastic or rubber
parts.
5. Cover the machine and all loose parts to protect
them from dust or other contaminants while in
storage. Place the machine in a dry location.
6. On water-cooled units, disconnect the water
lines. Use compressed air to blow out all
remaining water in the condenser. Insert a
screwdriver (Fig. 26) to open the water valve.
Note: Failure to purge the machine of water
can result in severe damage to the cooling
system. This task should be performed by a
qualified service technician.

SOURCE(S) BEFORE PERFORMING ANY ROUTINE
MAINTENANCE. PERSONAL INJURY OR DAMAGE
TO THE MACHINE COULD RESULT IF THIS
PRACTICE IS NOT OBSERVED.
Daily: Inspect the machine for signs of product leaks
past seals and gaskets. If proper assembly does not
stop leaks around gaskets or seals, check for improper
lubrication and worn or damaged parts. Replace parts
as needed.
Periodically: Inspect the scraper blades (Fig. 27) to
see that they are straight and sharp. If worn, damaged
or warped, the blades will not scrape the cylinder walls
correctly and the freezing capacity will be reduced.
Clean the drip chute assembly (Fig. 28) with warm water

TROUBLESHOOTING GLOSSARY
Troubleshooting Glossary
Ambient Temperature. The temperature of the air in the immediate vicinity of the operating machine. High am-
bient temperature can reduce the capacity with an air-cooled condenser.
Capacity. The total capacity of frozen product that a freezer can produce in a given period usually stated in gal-
lons per hour (G.P.H.).
Carbtube. Flow control device that allows product and air to be blended together. The air added to the product is
labeled as over-run. The over-run helps provide a thick and rich product. If the carbtube is not used the product
will be heavy, wet, grainy, will not thicken and product temperatures will be lower than the specified 18-21 degrees
soft serve and 25-28 degrees shake. Carbtubes are not used in frozen beverage machines.
Condenser. The part of the refrigeration mechanism that receives hot, high-pressure refrigeration gas from the
compressor and cools gaseous refrigerant until it returns to a liquid state.
Consistency. The viscosity or thickness of the product in the freezing cylinder.
Consistency Control. A control that senses the thickness or viscosity of the product in the freezing cylinder.
Dasher. The part of the freezer that scrapes frozen product off the inside of the freezing cylinder and blends the
product. In a gravity freezer, this assembly also moves the product forward to be dispensed.
Front Plate. Seals the front of the freezing cylinder and provides a means for dispensing the product. On gravity
fed freezers, the front plate indirectly holds the dasher in place via the stator rod. It also provides compression for
the rear seal.
Freezing Cylinder. The part of the refrigeration mechanism in which the refrigerant vaporizes and absorbs heat.
This is the part of the freezer where the liquid product is frozen.
Magnetic Agitator. Installed in the mix-pan reservoir and used to maintain product temperatures and prevent
product separation. The bottom of the agitator must be lubricated.
Mix-pan. Is the top container that product is poured into. It is used as storage until product is needed for the
freezing cylinder. Soft Serve and Shake machines have refrigerated mix-pans to prevent bacteria from forming.
Mixing Product / Product Temperatures. If your using a product that has to be mixed with water or other ingre-
dients, it is imperative the product is mixed consistently everyday. If not, the machine will not run consistent and
could possibly damage components. This is very important with frozen (slush) beverages. Always mix to the
product manufactures recommendations. The machine is designed to operate with a frozen product that falls
within these temperatures (soft serve 18-21 degrees, yogurt 17-20 degrees, shake 25-28 degrees, non-alcoholic
frozen beverage 25-28 degrees and alcoholic frozen beverage 18-22 degrees).
Overrun. The volumetric increase of product from the liquid to the solid state due to the incorporation of air into
the frozen product. Overrun is states as a percentage.
Product Breakdown. The decline in frozen product quality resulting from excess agitation or temperature varia-
tions of product that has been in the freezing cylinder too long. Product, which has broken down, may be grainy,
wet and or heavy. Product breakdown is easily detected by taking the temperature of the dispensed product.
Temperatures will always be lower than recommended product temperatures.

Troubleshooting Glossary
Rear Seal. This part is stationary during operation and must not move. When installed and lubed properly, seals
mix in cylinder. When installed and lubed improperly, it causes main shafted bearing failure.
Rerun. The reuse of previously frozen product after it has melted to a liquid. Rerun is obtained when emptying a
freezer for periodic cleaning. Use caution when using rerun as it may contain high bacteria or Coli count, which
could contaminate the fresh mix with which it is combined. Freezers should never be started with rerun. If used at
all, it should be blended with fresh mix at a ratio of seven parts new mix with three parts old mix, after initial
freeze-down with fresh mix.
Scraper Blades. The component that scrapes the frozen product from the freezing cylinder surface. Blades must
be sharp, as dull blades will leave product on the freezing cylinder, insulating the mix from the refrigerant.
Spinner Assembly. An externally installed or internally installed component used to blend a base product with
flavoring or other particulate.
Spigot Plunger. The mechanism on the front plate through which the product is dispensed.
Starved Cylinder. A starved cylinder is often mistaken for a freeze up or product too thick. A starved cylinder
(starving) is created when a larger percentage of frozen product is dispensed from the freezing cylinder than the
percentage of liquid product entering the freezing cylinder from the mix-pan. There are several causes of starving.
1. Overdrawing: Dispensing more product from the machine than it’s designed to do. This would occur if a ma-
chine were undersized for its application.
2. Inserting the carbtube prior to pouring the initial product into the mix-pan at the start of each day. This forms a
vacuum and traps a large percentage of air in the cylinder; therefore the cylinder will not fill with product.
3. When carbtube hole setting is not set on the correct hole size for the amount of product being drawn. Exam-
ple, if several customer dispense product from the machine with the carbtube set on the small hole, it will not
allow the freezing cylinder to be replenished with product in a timely manner. Change carbtube setting to a
larger hole.
4. Carbtube not being cleaned, thus allowing product build-up in the carbtube holes. This restricts product from
entering the freezing cylinder.
5. Mix out light not working therefore not alerting operator the need to add product.
6. Pouring frozen or semi frozen product into the mix-pan reservoir. This will form a blockage in the carbtube
hole and not allow liquid product to flow into the cylinder.
7. Mix-pan too cold, allowing product to freeze in mix-pan and restricting product flow.
Stator Rod. Acts as a bearing surface. Helps enfold air for overrun. Transmits compression to the rear seal.
Helps mechanical torque system sense torque. Be sure to lubricate.
