MACHINE APPLICATION AND SPECIFICATIONS
Model XF124
The machine consists of a freezing cylinder with a rotating internal auger or beater bar that is belt-driven by an electric
motor. The auger has plastic scraper blades that scrape frozen product off of the inside of the refrigerated cylinder
walls.Theconsistencyorthickness controlintheXF124isaveryreliablemechanicalcontrolsystem,wherebyatorque sensing
assembly on the drive motor determines when the cooling compressor should be turned off to maintain desired
product consistency. A self-closing dispensing valve is attached to the front of the freezing cylinder and this valve
assembly is transparent to allow the user to view the product in the freezing cylinder. The unit has an adjustable consistency
control inside the right side panel of the machine (which should not be adjusted with the machine on or plugged
in) and a mix low indicator light on the front of the machine to alert the user when more mix should be added to the
hopper machine.The hopper of the machine is refrigerated to precool the product before it goes into the freezing
cylinder so that your freeze and recovery times will be shortened. When properly maintained and operated, the XF124
will provide many years of service. Proper care includes regular cleaning and maintenance. To minimize the amount
of maintenance necessary, follow the operating procedures outlined in this manual.
Product Tips
The XF124 was designed to dispense a wide variety of frozen beverages including frozen margaritas, daiquiris, fruit
juice, lemonade, slushes, and other frozen cocktails. These products can be served in consistencies ranging from thin
to fairly thick. A red spring is used on the drive motor to adjust product consistency to serve thin to medium products.
The yellow spring is used for thicker products. The spring is located next to the drive motor behind the right side panel.
Over an extended period of time, some products, such as frozen cocktails that contain alcohol, have a tendency to
separate or stratify in the machine hopper. Separation of product in the hopper can result in frozen product quality
inconsistency, so it is advised to stir the mix in the hopper occasionally to eliminate product separation.

Contact your local health department regarding its regulations for proper mix handling and storage.
Feed Tube
The XF124 uses a metering device, known as a feed tube, to feed a ratio of liquid mix and air into the freezing cylinder,
and to reduce the frozen product rising out of the freezing cylinder back into the hopper.
Product Mix
Freezing characteristics are affected by the amount of sweeteners, solids, and alcohol in the mix. The amount of
sweeteners and solids is called BRIX and can be measured with a refractometer. A BRIX reading of between 11 and
16 will provide optimum machine operation. Mixes with this BRIX level will freeze down to a smooth, uniform
consistency. Mixes with a BRIX measurement above 16 may take longer to freeze and may be soft and/or wet in
consistency when dispensed. Mixes with a BRIX level below 11 may have larger ice crystals and may dispense slower
than usual. Alcohol content also affects productfreezingcharacteristics, as a higheralcohol content lowers the freezing
temperature of the mix and may prevent the machine from cooling the mix to the temperature where the mix will be at
the proper thickness. For maximum output capacity, pre-chill mix before adding it to the machine. Pre-chilled mix
reduces the cooling system workload and speeds the initial freeze time. It is normal for output capacity to decrease
when warm mix is added or when the machine is operated in a warm or humid location.

INSTALLATION
1. Place the XF124 on a level counter that is stable and strong enough to safely support the machine’s full weight with
mix in it (typically 250 lbs).
2. Make sure machine is to be placed in a location that is within 6’ of a properly grounded circuit and allows adequate
space (at least 6 inches) on each of the left, right, and back sides of the machine for proper air circulation.
NOTE: Failure to allow adequate ventilation will substantially reduce the machine’s performance, may
cause damage to the machine, and may void the warranty due to improper operation of the machine.
NOTE:Locating the unit in high ambient temperatures (over 90°F) will reduce the performance of the machine.
3. Reverse the position of the dispense valve handle. During shipment the handle is positioned close to the unit to
prevent damage. Remove the pin on the dispense valve and rotate the handle in the dispense valve half a turn.
This will position the end of the handle away from the machine about 4 inches. Replace the pin in the dispense
valve and the valve is ready for use.
4. Be sure ON-OFF-CLEAN switch (toggle switch located underneath the lighted sign on the left front side of the machine)
is in the “OFF” position.
5. Connect the power cord directly to a properly grounded 120V/60Hz, 20 Amp DEDICATED circuit. No other
equipment should be on the same circuit as the XF124.

Page 4
Model 3311
Do not use an extension cord to power the XF124 or damage to the machine may occur due to the voltage drop in the
extension cord.
DO NOT MODIFY THE POWER CORD OR PLUG IN ANY WAY OR SEVERE BODILY INJURY CAN OCCUR.
ONLY OPERATE THE MACHINE ON A 3 PRONG GROUNDED PLUG OR SERIOUS BODILY INJURY MAY OCCUR.
Running the XF124 on an inadequate power supply or otherwise not complying with the requirements of this section will
cause damage to the machine and will void the warranty.
6. Pour liquid mix into the hopper.
7. Insert the feed tube in the hopper hole (if desired).
8. Turn the power switch to the ON position to begin freezing the mix.
OPERATION AND ADJUSTMENTS
How to Operate
1. Sanitize unit before use.
2. Fill the mix storage hopper and
3. Turn power switch to “ON” position.
4. Allow product to freeze in barrel. Compressor will turn off when product reaches pre-set consistency.
5. To dispense product pull down valve handle and release when done.
6. If product consistency is not as desired, adjust per the instructions herein.
7. Refill mix storage hopper when “mix out” light is ON.
8. Clean the unit regularly following local health codes.
9. Perform maintenance when necessary to increase the life of the unit. See the chart in this manual for regular
maintenance schedule.
Mix Low Function
1. The XF124 senses when mix is low in hopper. When the mix level in the hopper is low, the RED mix low light
located in the front of the machine next to the valve block will illuminate red.
NOTE: Do not run the unit under mix low conditions for long periods of time. This can affect machine performance or
damage components of the machine.
Consistency Adjustment
From time to time, it may become necessary to readjust the consistency or thickness of the XF124 to
compensate for variation between different mixes or to switch from one type of product to another. This
adjustment is made as follows:
1.
Disconnect electrical powerto the machine .
WARNING: Do not attempt to adjust the machine until electrical power has been
disconnected.
2. Remove right side panel (facing the front of the machine, the right side panel)
3. Use the adjustment screw, situated on the front of the drive motor mounting bracket

to change product thickness. Turn the thumbscrew (3 full turns for red spring, 1 turn for
yellow spring) to make a noticeable change in consistency.
NOTE: Clockwise (when looking down at the top of the adjustment screw) is for thicker product consistency
and counter clockwise is for thinner product consistency.
4. Reinstall the side panel, reconnect power.
5. Turn machine to “ON” and allow it to freeze to desired consistency.
6. Check product. Repeat process until desired consistency is achieved.
NOTE: When making changes to a thicker setting, recheck consistency again after the compressor has stopped
cooling and has cycled off. When adjusting (counter-clockwise) to a thinner consistency, a large portion of product
must be drawn from the dispense valve to reduce the product thickness below the new set point, and then allow the
machine to refreeze product to the new setting, which may again be checked once the compressor has stopped
cooling and the machine has cycled off.
CARE AND CLEANING
Cleaning and sanitizing frequency must be followed according to state and local health department regulations.
NOTE: Each time the machine is fully disassembled, all food zone machine components (all parts of the machine
that come in contact with the product being dispensed) must be thoroughly washed and sanitized using procedures
recommended by the local health department. In lieu of local health department recommendations, use a three
compartment sink; one compartment to wash parts in detergent, one compartment to rinse, and one to sanitize.
Drain and Rinse
1. If the machine is empty, proceed to the Disassembly and Cleaning section below. If there is product in the
machine, turn the front panel switch to “CLEAN” and drain the remaining mix from the machine by dispensing the
product into a bucket from the dispensing nozzle.
2. Close the dispensing valve and turn machine to “OFF”.
3. Remove the feed tube and pour water into the storage hopper. Allow the water to fill the freezing cylinder.
4. Turn the panel switch to “CLEAN” for 5 minutes.
5. Open the dispensing valve and drain the water from the machine.
6. Turn the machine “OFF”.
7. Repeat steps 3-5 until the water drained from the machine is clear.

Preventative Maintenance Procedure (Every 6 to 12 Months)
A preventative maintenance visit should be performed every 6 to 12 months depending on the usage and environ-
ment where the unit is placed. (Ex. seasonal machines - once before season, year round machines - twice per year).
The following procedures should be performed during a preventative maintenance visit. This does not take the place
of daily care and cleaning procedures as described by local health codes and the manual. PM kit #W0890157 con-
tains the standard replacement parts needed for preventative maintenance including o-rings, standard seal kit stator
bearings and drive belt. Units with a coconut oil product seal should order all parts separately. Units with scraper
blade beater bar will require the scraper blades be ordered separately.
• Verify ventilation is adequate (Air-cooled units: 6” minimum on both sides, open at top, and as far as possible from
dust sources; Water-cooled units: 0” on both sides, 3-6” at rear of unit and open at top).
• Verify adequate water flow and drain connections on water-cooled versions.
• Check product temperature and consistency for proper setting (refer to product manufacturer’s recommendation) -
adjust if necessary. Where equipped be sure to check the temperature in both the hopper and cylinder.
• Ensure product is being mixed properly and is within specification (check brix - most products should be around
13% - refer to product manufacturer’s recommendations for exact recommended brix).
• Check for any leaks.
• Empty product from the unit. Disassemble unit completely (as if for cleaning).
• Clean and sanitize all disassembled parts following the cleaning instructions in the manual.
• Clean and sanitize hopper, freezing cylinder and splash zones on the machine.
• Check condition of all panels and lids - replace if necessary.
• Check beater bar scraper blades for wear if equipped - replace once per year minimum.
• Check beater bar for signs of wear - replace if necessary. Verify alignment when replacing.
• Check valve body gasket for wear - replace once per year minimum.
• Check valve body knobs (used to hold valve body in place) - replace if necessary.
• Check condition of shaft seals and stator bearings - replace once per year minimum.
• Inspect drip cup at back end of freezing cylinder for signs of seal leakage.
• Replace o-rings on hopper float (where necessary), dispense valves and feed tubes (lubricate).
• Lubricate parts where appropriate (dispense valve o-rings, feed tube o-rings, rubber boot of stationary shaft seal).
• Re-assemble unit and sanitize hopper and freezing cylinder by running CLEAN cycle.
• Clean and sanitize spinner if equipped.
• Check operation of merchandiser and mode lights - replace light bulbs if necessary.
• Clean reusable filter if equipped. Check condition of filter and replace if necessary.
• Clean condenser.
• Inspect the drive shaft and motor shaft bearings for excessive wear (drive shaft hole rounding out) - replace if
necessary. Verify alignment when replacing.
• Check V-belt tension (should be 1/2” - 5/8”) and verify all set screws are tightened - adjust if out of range. Replace
belt once per year minimum.
• Verify compressor operation and machine controller operation.
• Check electrical connections (outlet should be properly grounded with amperage capacity equal to or over the
amperage specified on the serial tag).
• Check fan operation (condenser fan) and clean fan blades if necessary.
• Review proper periodic care and cleaning instructions (disassembly, cleaning, sanitizing, lubrication, and
re-assembly) with store personnel. Train store personnel to follow proper procedures (stress importance of store
level maintenance ie. lubrication, filter cleaning, etc.).
• Make sure store personnel have appropriate supplies (lubricant, cleaning brushes and sanitizer) to care for
machine.

How to Clean Condenser (Air-Cooled Unit Only)
NOTE: Loss of refrigeration efficiency will result if condenser is allowed to become dirty. Excessive compressor run
time or loss of capacity are a good indication that the condenser needs to be cleaned.
1. Disconnect electrical power.
2. Remove side panels.
3. Place a damp towel over the side of the condenser opposite the fan motor.
4. Use compressed air or CO2 blow out dirt from the fan side of the condenser. An alternate cleaning method is to
use a condenser brush and vacuum cleaner.
& CAUTION: Procedure can create a loud noise.
How to Clean Exposed Filter (Air-Cooled Unit Only)
1. Slide exposed filter out of the rails by pulling forward on the filter. It is recommended to remove the filter by using
the palm of your hand and applying even pressure to the face of the filter.
2. Clean filter with liquid soap and water.
3. Soak filter for 15 minutes.
4. Rinse filter with heavy stream of water, opposite the direction of air flow. Allow filter to dry.
5. Slide the filter into the rails until the filter contacts the stop on the top rail.
How to Clean Concealed Filter (Air-Cooled Unit Only)
1. For concealed filters lift lid and pull up on filter tab to remove filter.
2. Clean filter with liquid soap and water.
3. Soak filter for 15 minutes.
4. Rinse filter with heavy stream of water, opposite the direction of air flow. Allow filter to dry.
5. Slide filter into top of filter cover with removal clip up and the air flow arrows facing the existing panel.
How to Adjust Belt
CAUTION: Unplug the machine before performing any adjustments. This procedure must be done by
a qualified technician.
Check the belt tension. The proper belt deflection is 1/2” over all. If the deflection
is more than 1/2” the motor will need to be lowered. If the deflection is less than
1/2”, the motor will need to be raised. Follow this procedure to adjust the motor to
achieve proper belt tension. (See Figure FF)
1. Unplug the machine and remove both side and rear panels.
2. Locate the motor flange bearings. These are the side mounted bearings that
hold the motor to the cradle. The motor is double shafted and the shaft
extends through a bearing on each end. The bearing is held to the motor
cradle by two allen bolts on each bearing.
3. Loosen the allen bolts on each bearing. Do not loosen the setscrews that hold
the bearing collar to the motor shaft.
4. Lower the motor or raise the motor as needed. The motor must be kept level
from front to back. Do not lower or
raise only one end of the motor. This will result in excessive belt wear and belt noise.
5. Tighten all four allen bolts down. Align the motor pulley with the top pulley if needed.
Figure FF
6. The motor pulley should be in alignment with the large (driven) top pulley. Use a straight edge along the
top pulley.
7. If the pulleys are not in alignment, loosen the setscrew on the motor pulley and move either in or out as needed.
8. Tighten the setscrew back down on the motor shaft (use of non-permanent loc-tite is recommended). Please be
sure the setscrew is tightened down on the flat surface of the motor shaft.
9. Return the unit back to service.
How to Change Back Lit Sign Merchandiser Bulb
1. Remove the two screws located on the top of either side of the sign.
2. Lower the metal enclosure that frames the merchandiser insert.
3. Pull merchandiser enclosure down and out.
4. Replace bulb inside by pulling bulb straight out of the socket. Firmly insert the new bulb into the socket.
5. Reassemble. For ease of assembly, put merchandiser and plastic lenses in light box before placing metal
enclosure back on.
