The freezer is equipped with an automatic defrost system to allow the frozen product to melt back to a liquid. This
eliminates any large ice crystal formation or poor product consistency that may develop. This automatic timer can be
pre-programmed to occur at desired times of the day. The defrost cycle takes four hours to complete and should be
programmed in.
Unpacking and Inspection
Shipment and Transit
The freezer has been operated and tested at the factory. Upon arrival the complete freezer
must be thoroughly checked for any damage which may have occurred in transit. NOTE: A
Tip (N) Tell warning device is placed on each shipping carton at the factory. If the arrow tip is
blue, the carton has been tipped in transit. (See Figure 1)
IMPORTANT: The carrier is responsible for all damage in transit whether visible or con-
cealed. DO NOT PAY THE FREIGHT BILL until the freezer has been checked for damage.
Have the carrier note any visible damage on the freight bill. If concealed damage and/or
shortage is found later, advise the carrier within 10 days and request inspection. The cus-
tomer must place any claim for damage and/or shortage with the carrier. The manufacturer
cannot make any claims against the carrier.

Periodic Inspection
1) Check the CO2 tank pressure gauge on the cylinder regulator assembly. Replace if tank pressure drops below
red line.
2) Make sure the unit contains a sufficient supply of syrup and alcohol.
3) Check to see that there is sufficient air space on both sides of the unit. Proper air circulation is required for
efficient operation. Make sure that the louvers are not obstructed at any time. CAUTION: Failure to provide
minimum air flow clearance will void the freezer warranty. (See Locating Freezer)
Freezer Assembly and Installation
Attaching Freezer to Base Cart
1) Unbox freezer (top half)
a) Remove both side panels and then use a 7/16” socket to remove the 2
bolts at the bottom of the freezer that hold it to the shipping pallet.
b) Cut the wire tie (note red tag) on freezer drive motor. (Figure 2)
c) Leave right side panel (when facing front of freezer) off.
2) Place a bead of silicone sealant all the way around the edge of the base
cart top. (See Figure 3)
3) Place beverage freezer onto the base cabinet on top of the bead of silicone.
Position freezer over mounting holes before sealant sets. (Figure 4)
4) Secure top half of unit to base cart by installing 7/16" bolts and nuts using
Figure 2
the same holes used to secure the freezer to shipping pallet.
5) Open rear door of base cabinet and place black plastic bushing in wire hole in the top
of the cabinet.
6) Feed the 2-multi-pin connectors found in the freezer down into the base cabinet
through the hole in the top of the lower cabinet. Connect each connector from the
cabinet to matching connector in the freezer. (See Addendum 5)
CAUTION: Do not leave too much slack in the wires as they could get caught in the fan
blades. Use wire tie and holder to secure wires in place. See electrical diagram.
7) Remove the base cart electrical box cover (located in the upper right corner of the base
cart). Feed the power cord (found inside lower rear right side of freezer, near the terminals)
through hole into the base cart and then feed it into the hole in the rear of the electrical
box. Connect power cord wires. (See Addendum 3 and 4)
Figure 3
8) Route the product feed tubing (located in the freezer) down through hole into base cabinet.
Route the tubing to the top part of the freezer following the same path as the wiring.
9) Attach the tubing to the John Guest 90° elbow fitting which is located in the base cabinet behind the electrical
box. Make certain that the tubing is pushed all the way into the fitting. (Figure 5)

Locating Freezer
1. Locate freezer close to a source of potable water. Water pressure must be 15-psig or higher.
2. Connect freezer to a properly grounded 115-120 VAC, 60Hz single-phase electrical circuit with a 20-amp
(NEMA 5-20R) minimum-rated disconnect switch (not provided) that is fused at 20 amps (slow-blow).
CAUTION: Safe operation of this unit can only be achieved if the freezer is properly connected to an appro-
priate grounded, electrical receptacle that complies with current national safety standards. The manufactur-
er cannot be held responsible for damage and/or injury caused by failure to connect the unit to an appropri-
ate source of power.
3. A minimum air clearance of 6" is required on both sides of the freezer during operation.
CAUTION: Restricting air flow through the freezer will greatly reduce the output capacity as this is an "Air
cooled" unit. Air is drawn in to cool the unit through the right side (facing front of freezer) and exhausted
through the left side. Failure to provide minimum air flow clearance will void the freezer warranty.
Connecting City Water Source Line to Unit
The National Sanitation Foundation requires the following for an NSF approved water hook-up:
• A quick disconnect water connection or enough coiled tubing so that the machine can be moved for cleaning
underneath.
• An approved backflow prevention device, such as a double check valve to be installed between the machine and
water supply. On units plumbed to permanent water line, installation of a water filter/softener system is
recommended to prevent lime and scale build-up in the machine.
• Water pipe connections and fixtures directly connected to potable water supply shall be sized, installed and
maintained in accordance with Federal, State, and Local codes.
1) Gather 3/8" OD low-density polypropylene tubing or 3/8" OD copper tubing with a
1/4” SAE Flare Connection (not provided).
2) Connect the tubing to the 1/4” SAE Flare fitting found under the left side of the
base unit. (Figure 6)
3) Connect the other end of the tubing to a water source.
NOTE: Where water quality is low an activated charcoal water filter may be needed
to achieve adequate frozen product overrun and proper flavor profile.
If water pressure exceeds 50 psig install a water regulator such as Shurflo
# 183-059-06, or equivalent, to inlet water line.
Figure 6
Installing CO2 Regulator Assembly on CO2 Cylinder
1) Unscrew protector cap (with chain attached) from CO2 cylinder valve. Open CO2 cylinder valve slightly counter-
clockwise to blow any dirt or dust from outlet fitting before installing CO2 regulator assembly, then close valve.
CAUTION: CO2 cylinders contain gas under high pressure. Handle cylinders with care.
2) Remove shipping plug from CO2 regulator assembly coupling nut, then make sure gasket is in place inside the
nut. Install hose regulator assembly on the CO2 cylinder, then tighten coupling nut. DO NOT OPEN CO2
CYLINDER VALVE AT THIS TIME.
NOTE: Before attempting to activate the systems, insure that all manual shut-off valves, located in the lower back
compartment of the base cabinet, are closed (vertical position). Do not open them until instructed to do so.
Installing CO2 Regulator Assembly on Existing CO2 Line
NOTE: Bulk system must have 100 psi to operate.
1) Purchase a low pressure regulator set. (Norgren Model C81-570-2 recommended)
2) Disconnect carbonator and BIB pump lines. Remove existing regulator set and install low pressure set.
3) Reconnect lines to outlet side of set. Bring in bulk system line to inlet of regulator.
NOTE: Install a cutoff valve between regulator and bulk system.

Filling CO2 Lines
CAUTION: CO2 lines should be filled slowly to prevent the possibility of damaging components. Open tank shut off
valve slowly until it is completely open.
NOTE: Open valve all the way to prevent leakage around the valve shaft.
Adjusting CO2 Regulators
NOTE: CO2 regulators are pre-set at the factory. Check for accuracy.
1) Adjust the CO2 regulator that drives the bag-in-box syrup
pump and alcohol pump to 60 psi. Turning regulator
adjustment clockwise raises the pressure. Tighten locknut at
this setting. (Figure 7)
CAUTION: The use of excessive pressure (above 75 psi) will result in
pump seizure.
2) Adjust the CO2 regulator, connected to the carbonator, to
90 psi. NOTE: Do not exceed 120 psig, the carbonator pressure
relief setting. Turning regulator adjustment clockwise raises the
pressure. Tighten locknut at this setting.

8) Push down on bracket until it firmly holds the bottle in place and tighten the knob.
Figure 9
Note: If you are using partially empty bottles place the emptiest bottle at the end of the
reservoir farthest from the reservoir outlet tubing. This will allow the partially filled bottle to be emptied first.
Activating Alcohol and Syrup System
NOTE: See Addendum 2 photo for location of components
1) Open manual valve located between gas powered alcohol pump and the alcohol electric solenoid with flow
control. This activates the alcohol supply system.
2) Open the manual valve between the gas powered syrup pump and the syrup electric solenoid with flow control.
This activates the syrup supply system.
3) Liquid should fill the lines and the pumps should cycle.
Checking BRIX (Water-to-Syrup Ratio) of Dispensed Product
NOTE: The water, syrup, and alcohol ratio are all pre-set at the factory to meet drink quality standards.
Adjustment of these ratios can only be done by authorized service technicians.
A graduated cylinder that holds at least 17 ounces (500ml) is needed to test the BRIX. A measuring cup can be
used if a graduated cylinder is not available.
1) Switch back cabinet control box switch (Figure 10) to "TEST" mode.
2) Switch Freezer control to "CLEAN".
3) Open test output port valve.
Water Ratio Check:
NOTE: See Addendum 2 for location of components.
1) Close all manual valves except the water valve.
2) Put test output port tube into the graduated cylinder.
3) Toggle "Sample Timer" switch to "ON".
4) Water will flow into the graduated cylinder for 10 seconds.
5) When water flow stops, measure the water volume in cylinder. The proper
setting is 13.5 oz. (400ml).
6) If the volume is not 13.5 oz (400ml), consult the Troubleshooting Guide in this
Figure 10
manual.
Syrup Ratio Check:
1) Close all manual valves except syrup.
2) Put test outlet port tube into the graduated cylinder.
3) Toggle "Sample Timer" switch to "ON".
4) Syrup will flow for 10 seconds.
5) When flow stops, measure syrup volume in cylinder. The proper setting is 3.7 oz. (110ml).

Checking BRIX (Water-to-Syrup Ratio) of Dispensed Product (cont’d)
6) If the volume is not 3.7 oz. (110 ml), consult the Troubleshooting Guide in this manual.
Note: Due to the thick viscosity of the syrup, it may be necessary to purge the syrup line to obtain an accurate flow
rate reading. Purge the syrup line by first closing the syrup valve, opening the water valve and then momentarily
turning on the test switch. This will purge all syrup from the lines and allow them to drain properly for a correct
reading of the syrup flow rate.
7) After the correct water and syrup flow rates are set, open both the water and syrup valves.
8) Turn the "TEST" switch to "ON".
9) Dispense mixed water and syrup though the test line.
10) Check the BRIX of the mix using a refractometer. Verify that the solution has a BRIX reading of 15.
Alcohol Ratio Check:
1) Close all manual valves except for "ALCOHOL".
2) Put test outlet port tube into the graduated cylinder.
3) Toggle "Sample Timer" test switch to "ON". Product will flow for 10 seconds.
4) When flow stops, measure volume in the graduated cylinder. The proper setting is 3.4 oz. (100ml).
5) If the volume is not 3.4 oz. (100ml), consult the Troubleshooting Guide in this manual.
Checking Unit for Syrup, CO2, and Water Leaks
After checking all the ratios, open all manual valves. Open the cabinet's front and rear doors and check for any
leaks. If any leaks are located, contact an authorized service technician to fix the leak. Close and lock the front and
rear doors.
Defrost Timer
Setting Clock (Time of Day)
1) The timer is located inside the freezer back lit merchandiser box on the top front of the freezer. (Figure 11)
2) Rotate the timer dial, in the direction of the arrows, until the mark lines up with the current time of day.
3) The timer has a 2 week battery backup that requires 24 hours to charge fully.
Programming Defrost (Automatic)
1) Push all switch pin actuators toward the outer edge of the programming disk.
2) Set freeze time by pushing the switch pin actuators toward the center of the
programming disk. (Figure 11) An adequate defrost cycle should last
3-1/2 hours.
Note: Each pin actuator is equivalent to 15 minutes. Do not run a defrost for more
than 4 hours. May result in damage to seals.
Figure 11
Filling Freezer
1) Open all product manual control valves.
2) Set lower control box Power switch to "ON" and Sample Timer switch to "OFF" and Control Select switch
to “Run". (Figure 10)

Cleaning
NOTE: Before cleaning, all product should be drained from the freezing cylinder, pres-
sure vented, and either the valves set closed or product removed from the machine.
1) Disassemble the dispensing valve by first removing the dispensing valve pin
(Figure 12)
2) Push up on the dispensing valve plunger and pull out the dispensing handle.
The plunger assembly complete with spring and "O" Rings can then be removed
as a unit.
3) Remove knobs and carefully remove the freezer dispensing valve assembly.
4) Remove the O-Rings from the plunger assembly and back of the dispensing
valve body.
Figure 12
NOTE: The best way to remove an O-Ring is to first wipe off all of the lubricant using a clean
paper towel. Pinch the O-Ring upward with a dry towel between your index finger and thumb.
When a loop is formed in the O-Ring, roll it out of the groove with your other thumb. Always
remove the O-Ring farthest from the end of the plunger first. (Figure 13)
5) Carefully inspect the O-Rings for wear, nicks or cracking and replace if necessary.
6) Carefully pull out the auger assembly taking care to avoid damaging the rear seal
assembly at the back of the freezing cylinder.
7) Remove stationary portion of the shaft seal assembly (silicon carbide ring and rubber
boot) from the back end of the freezer cylinder. This is accomplished by reaching into
the cylinder and pulling the seal out with your index finger. (Figure 14)
8) Slide the rotary seal off of the auger shaft. (Figure 15) Inspect both seal compo-
nents carefully for nicks or cracks. Replace seal if defective. NOTE: To prevent
leakage both surfaces of the seal must be smooth with no chips or cracks.
9) Wash all components in a detergent solution, sanitize and allow to air dry.
DO NOT WASH COMPONENTS IN A DISHWASHER.
Figure 13
10) Wet the inner rubber lip of the rotary portion of the seal and the back end of the
auger shaft with water. Slide rotary portion of assembly onto the auger shaft, RUBBER
Figure 14
FIRST, with the smooth sealing surface facing toward the back of the auger.
11) Insert the stationary portion of the seal into the grooved rubber boot with the
polished surface facing out (forward), away from the rubber boot. Lubricate the
grooved rubber exterior portion of the boot with silicone lube and insert it straight
back into recess at the back of the freezing cylinder, RUBBER FIRST.
NOTE: On the circular portion of the seal, make sure that the groove is toward the
rubber (back of freezer).
Figure 15
12) Reassemble the dasher assembly, as shown in Fig.16. Insert the larger front and
smaller rear white plastic bearings into dasher, then slip in the stator rod. Carefully
and slowly guide the auger into the freezing cylinder taking care not to
damage the seal assembly. Turn auger shaft until it engages the square drive coupling.
13) Reassemble the dispensing valve assembly. (Fig. 12) Be sure to lubricate o-rings and relief vent
before assembling.
14) Thoroughly wash and sanitize all components. Inspect and lubricate
all surfaces of the large O-Ring and refit it into the rear of the valve
assembly. Install the valve assembly on the front studs and tighten knobs
until they are finger tight. Do not use tools to tighten knobs.
IMPORTANT: Failure to lubricate the large "O" Ring can result in product
leakage.
15) Reinstall the O-Rings on the plunger assembly and lubricate the O-Rings
and plunger. Reassemble the valve and replace the retainer pin.

Controls and Product Issues
Consistency Adjustment
NOTE: The following product consistency (thickness) control adjustment procedure
requires removal of the right side panel. It is suggested that a qualified service
technician make this adjustment because side panel removal exposes hazardous
moving parts.
Warning: Do not attempt freezer adjustments until electrical power has been
disconnected.
It may become necessary to readjust the consistency setting (thickness) to
compensate for variations.
1) Disconnect electrical power.
2) Remove right side panel (facing freezer).
Figure 17
3) Use the adjustment screw located on the top, front of the drive motor mounting bracket to change product
thickness. (See Figure 17).
• Clockwise for thicker product consistency.
• Counterclockwise for thinner product consistency.
NOTE: It may require up to three 180° turns of this adjusting screw to see a noticeable change in product thickness.
4) Turn freezer to "ON" and allow it to freeze to desired consistency.
5) Wait 15 to 20 minutes, check product consistency (thickness) and repeat as needed.
6) Reinstall the side panel and reconnect power.
Mix Out Lights
Red indicator lights, located on the front of the freezer, illuminate if the unit runs out of CO2, syrup, water or alcohol.
When a light is on, the unit will not fill or freeze product.
Freezer Controls
NOTE: This dispenser has several power switches, that must be set in their operating position for the unit to operate
properly.
"ON/OFF/CLEAN" SWITCH
The "ON/OFF/CLEAN" switch is a three-position toggle switch located on the front of the freezer. The left (facing the
machine) position is the "ON" or freeze position. The middle position is the "OFF" position. The Right position is the
"CLEAN" position (the auger is turning but the compressor is off).
Lower Base Control Panel Switches
All of the following switches are located on the lower control box, inside the rear cabinet door. (See Addendum 2 at
the back of the manual)
Power Switch
This is the unit’s main power switch.
• On - power is supplied to the base unit.
• Off - No power is supplied to the base unit.
Control Switch
This switch determines whether the unit is in the test mode or operating mode.
• Test - The Test switch is used to check the BRIX of the product allowing the Timer Switch to control
the solenoids.
• Off - Turns off the product feed system.
• Run - Allows product to be automatically fed to the freezer.
Timer Switch
• On - Activates the 10 second timer use to test BRIX and mix ratios
• Off - Timer is de-activated (normal operating setting).
Faceplate Relief Valves
A spring-loaded pressure relief valve maintains a safe pressure in the freezing cylinder. When filling the cylinder the
relief valve acts as a vent to allow the CO2 and air trapped in the freezing cylinder to escape. Venting the freezing
cylinder is essential to obtain proper overrun. The vent is also used to break a vacuum when draining a unit.
Dispensing Valve
CAUTION: The product in the freezing cylinder is under pressure, open the dispensing valve slowly when
dispensing product.

Product Quality
BRIX
Correct BRIX effects product flavor and freezing characteristics. Frozen product with low BRIX may have a weak fla-
vor, larger ice crystals, and a tendency to dispense slowly. Product with high BRIX has an overly strong flavor,
increased portion cost and results in lower freezer output capacity.
Alcohol Content
High alcohol content may prevent the freezer from serving product at proper thickness. High alcohol also suppress-
es the syrups ability to absorb CO2 and depresses the temperature of the frozen product. Too much alcohol will also
lower product overrun.
What Is Overrun?
Overrun is the increase in product volume, expressed as a percentage, resulting from the carbonation of the water.
The freezer chamber is pressurized, which holds the carbonation in the frozen product. The carbonation causes the
volume of the frozen product to increase when dispensed. For example, if one gallon (4.4 liters) of liquid mix is fed
into a freezing cylinder and one and a half gallons (6.6 liters) of frozen product is drawn out, the result is a fifty per-
cent volumetric increase, or a fifty percent (50%) "overrun".
Why is overrun important? The introduction of CO2 into the finished frozen product is essential from two stand-
points...taste and profitability. Frozen product that has a low percentage of overrun costs more to serve, appears
wet, and is heavy. The introduction of CO2 makes the finished frozen product taste richer. Too much overrun causes
the finished frozen product to be too light and fluffy, making it less satisfying and adversely effecting sales.
Factors Effecting Overrun
Syrups
The foaming agent in the syrup increases the ability of the frozen product to expand as it is dispensed.
Frozen Product Draw Rate Effects Overrun
Infrequent frozen product usage can result in a drink that may appear wetter and have less overrun.
Carbonation In The Water Effects Overrun.
There is a direct correlation between the level of carbonation of the water and the overrun of the frozen drink. Water
quality has a direct effect on carbonation. If it is difficult to achieve adequate overrun an activated carbon filter will
have to be added to the system. Also try readjusting the carbonator CO2 pressure.
Computing Overrun
1)
2)
3)
Weigh an empty cup.
Weigh this cup filled to the rim with liquid mix, and subtract the weight of the cup.
Draw a heaping cup of frozen product that contains no air pockets. Avoid tapping the cup as this artificially
reduces overrun.
4)
5)
Use a straight edge to scrape off excess product flush with the rim of the cup and weigh the cup.
Subtract the cup weight and use the overrun formula to determine overrun.

Operating Freezer
Unit Operation
1) Check that a "Mix Out" light is not illuminated. This indicates the freezer has an adequate amount of syrup,
CO2, alcohol and water (only one light will be ON at a time). Check machine after each product is filled.
2) Insure that the "ON/OFF" switch in the lower back compartment of the cabinet is in the "ON" position.
3) Insure that the "TEST/OFF/RUN" switch in the lower back compartment of the cabinet is in the "RUN" position.
4) Insure that the "ON/OFF/CLEAN" switch on the front of the freezer is in the "ON" position.
5) Allow the freezer sufficient time to reach desired product consistency (compressor will shut off).
6) Slowly open the dispensing valve to dispense frozen product.
7) If frozen product consistency is not correct, readjust following the instructions found in the PRODUCT
CONSISTENCY section of this manual.
Replenishing Syrup Supply
A vacuum transfer valve will automatically switch from an empty BIB container to a full one. Check BIB containers on
a regular basis and replace empty BIB following the procedure in the CONNECTING SYRUP SUPPLY section of this
manual.
Replenishing CO2 Supply
1) Open rear cabinet door.
2) Turn CO2 cylinder valve clockwise until it is fully sealed.
3) Detach Regulator assembly.
CAUTION: Remove connector slowly to relieve pressure build-up in the lines.
4) Unhook S-hook from safety chain.
5) Remove empty CO2 cylinder.
6) Slowly crack the valve on the new CO2 cylinder to blow any debris out of the valve.
7) Close the valve.
8) Place new CO2 cylinder in the place of the used CO2 cylinder.
9) Make sure that the CO2 regulator assembly coupling nut gasket is undamaged.
10) Attach the regulator hose on the new CO2 cylinder.
CAUTION: The CO2 lines need to be pressurized slowly to insure they are not damaged. Open the tank shut off
valve slowly until it is fully open. NOTE: Opening the valve all the way prevents leakage around the valve shaft.
Replenishing Alcohol Supply
1) Remove empty alcohol bottles.
2) Remove white tubular adapters from bottles.
3) Remove caps from new bottles and slide white plastic adapter over the neck until the bottle seats itself against
the shoulder of the adapter.
4) Bend the nozzle of the white plastic adapter over with your forefinger to stop liquor flow.
5) Insert the nozzle of the white plastic adapter into the reservoir port and allow adapter to drop into the reservoir
opening.
6) Stand inverted bottle upright.
7) Loosen the thumbscrew on the hold-down bracket and slide the hold-down bracket until it is centered on the
bottom of the bottle.
8) Push down on bracket until it firmly holds the bottle in place…tighten the knob.
9) Repeat for each bottle
Note: If you are using partially empty bottles place the emptiest bottle at the end of the reservoir farthest from the
reservoir outlet tubing. This will allow the partially filled bottle to be emptied first.

Servicing Dispensing Valves, O-Rings, and Freeze Cylinder Drive Shaft/Seal Assemblies
NOTE: Dispensing valve "O" Rings should be replaced every 120 days to correspond with quarterly preventative
maintenance visits.
The best technique for removing an "O" Ring is to first wipe off all of the lubricant using a clean paper towel. Pinch
the "O" Ring upward with a dry towel between your finger and thumb. When a loop is formed in the "O" Ring, roll it
out of the groove with your thumb. Always remove the "O" Ring farthest from the end of the plunger first. (See
Figure 13)

NOTE: Follow all health and safety standards.
5) Replace side panels.
Drive Belt Adjustment
CAUTION: Unplug the machine before performing any adjustments.
Check the belt tension quarterly. Proper belt tension is ½" deflection
measured mid way between the drive and driven pulleys. If the deflection is
more than ½" adjust the motor height to achieve proper tension using the
following procedure:
1) Unplug the unit and remove the side and rear panels.
2) Locate the motor flange bearings (W0380009) located at each end of
the drive motor. Two bearings support the motor, one on the shaft at
each end of the motor. The bearings are secured to the motor cradle
using two Allen bolts on each bearing.
3) Loosen all four bearing Allen bolts. NOTE: Do not loosen the setscrews
Figure 18
that hold the bearing collars to the motor shaft.
4) Lower or raise the motor as needed to achieve proper belt tension. The motor must be kept level from front
to back. NOTE: Excessive belt wear and belt noise can occur if the motor is not kept level.
5) Tighten all four Allen bolts down.
6) Align the driven motor pulley with the top driven pulley if needed. Use a straight edge along the top pulley. If the
pulleys are not in alignment, remove the setscrew from the pulley and move either in or out as needed.
NOTE: Use non-permanent Loc-Tite on the driven pulley setscrew and tighten down on the flat of the motor shaft.
