3) Turn power switch (toggle switch located underneath the electrical box) to "on" position.
4) Turn mode switch (rocker switch located next to power switch) to freeze position.
5) Allow product to freeze in barrel.
6) To dispense product pull down valve handle and release when done.
7) If product consistency is not as desired, adjust per the instructions on page 8.
Mix Considerations - General
Freezing characteristics are affected by the amount of sweeteners and solids in the mix, called BRIX. BRIX can be
measured with an instrument called a refractometer. A BRIX reading of between 11 and 14 will provide optimum
freezer operation. Mixes with this brix level will freeze down to a smooth, uniform consistency. Mixes with too high
a brix level will take longer to freeze down and will yield a soft, wet, frozen product. Mixes with too low a brix level
will have larger ice crystals and will have a tendency to dispense slowly. Note: Always take BRIX measurements
using mix that has been thoroughly blended, before it is frozen. Always allow frozen mix to thaw thoroughly before
taking a reading.
Alcohol content also affects product-freezing characteristics and may prevent the freezer from serving a product at
proper thickness.
For maximum output capacity always pre-chill mix before adding it to the freezer. Pre-chilled mix gives the freezer
a head start on the freezing process and will speed both initial freeze down and recovery time.
Figure H

Carburetor Assembly
Your new freezer uses a metering device, known as a carburetor, to feed the proper ratio of mix and air into the
freezing cylinder. For products such as dairy based shake mixes, the proper mix to air ratio is generally accepted
to be two parts mix to one par t air. This proportion yields a finished product that is both tasty and profitable. At this
ratio, one gallon of liquid mix will yield a volume of one and one-half gallons of frozen product.
The carburetor is a tube with a hole, or series of holes, bored through the side. It is located in the hopper and fits
in a hole that leads to the freezing cylinder. Air flows into the freezing cylinder through the top of the tube and mix
flows in through a smaller hole in the side of carburetor tube. The size of the mix inlet is balanced with the viscosity
(thickness) of the liquid mix and product draw rate, in such a way that the proper amount of mix is fed into the
freezer cylinder to blend with air at just the right ratio. Mix viscosity varies by mix type, mix temperature, and mix
age. Different serving rates also demand different feed rates. The Crathco carburetor has an outer sleeve that can
be rotated to line up with different hole sizes to provide ideal overrun under all operating conditions.
You will need to experiment to deter mine how much mix to add to the freezing cylinder at start-up. This can be
done by watching the level of mix through the clear plastic dispensing valve when filling the hopper. When the correct amount of mix feeds into the freezing cylinder install the carburetor tube in the "Off" position (outer sleeve set
between any two holes) and turn the freezer "ON" to freeze down to proper consistency.
Overrun
Overrun is the increase in product volume, expressed as a percentage, resulting from the entrapment of air in liquid
mix as it is frozen.
The rotating dasher blends air into the mix as it is frozen, resulting in increased product volume. For example, if
one gallon (4.4 liters) of liquid mix is poured into a freezer and one and a half gallons (6.6 liters) of frozen product
is drawn out, the result is a fifty percent volumetric increase, or a fifty (50%) percent “overrun”.
Why is overrun impor tant? The introduction of air into the finished frozen product is essential from two
standpoints...taste and profitability. Frozen product with a low percentage of overrun costs more to ser ve, appears
wet, and is heavy. The introduction of air makes the finished frozen product taste richer. Too much air causes the
finished product to be too light and fluffy, making it less satisfying and adversely affecting sales. The optimum
percentage of overrun varies from one type of mix to another, but 50% overrun is a good average. The ingredients
in some mixes take on and hold air easier than others. Overrun also affects profitability. For example, an increase
from 25% to 50% overrun represents a mix savings of 17%.
Uniform overruns insures consistent portion costs. If overrun is allowed to drop, it will cost more to serve a portion
of finished product.
Computing Overrun
1) Weigh an empty cup.
2) Weigh this cup filled to the top with liquid mix, and subtract the weight of the cup.
Note: Repeat this step only when changing mix sources, as mix weight will vary slightly from one supplier
to another.
Crathco®5311 & 5511 Manual Page 6
Crathco®5311 & 5511 Manual Page 7
Computing Overrun (cont.)
3) Draw a heaping cup of frozen product that contains no air pockets. Note: Use a spatula or other device to
help fill the cup completely. Avoid tamping the cup as this artificially reduces overrun.
4) Use a straight edge to scrape off excess product flush with the rim of the cup and weigh the cup.
5) Subtract the cup weight and use the overrun formula to determine overrun.
For Example:
If a full cup of liquid mix weighs 23 ounces (.652kg) and a full cup of frozen product weighs 15 1/2 ounces (.439kg),
then:
Note: Several companies manufacture scales that automatically read out the overrun for one-pint samples. A
scale of this type is a valuable tool and should be part of any well run operation. A trick is to place the empty cup
on the scale and zero it out first; this will then automatically eliminate the weight of the cup from the calculation.
Overrun has a major impact on the size of the finished frozen portion. As the percentage of overrun (air in the
frozen product) increases, the size of the finished portion also increases, yet the portion weight remains the same.
For example, an increase from 25% to 50% overrun will yield a 20% larger portion. Customers equate size with
perceived value so proper overrun will result in increased customer satisfaction. Experiment with carburetor
settings to achieve optimum overrun and product quality with each mix. Some products such as Cappuccino taste
better with low overrun. Experiment with different carburetor settings to find the ideal combination for each product.
Use of Stand-By Switc
h
The "STAND-BY" switch allows the operator to retain optimum product quality and conserve energy during
extended non-draw periods. The "Stand-by" mode keeps the mix in the hopper at a safe storage temperature
and allows the product in the freezing cylinder to return to a refrigerated liquid state. Switching back to "ON"
quickly returns the product in the freezing cylinder to proper serving consistency.
At the start of the "STAND-BY" period:
1) Select the "STAND-BY" mode by moving the mode switch to the middle position. The front panel
"STAND-BY" light will illuminate.
At the end of the "STAND-BY" period:
1) Turn the switch to the "FREEZE" position by moving the mode switch. The "FREEZE" light will illuminate.
2) When the freezer cycles off by reaching the desired temperatures you are ready to start serving.
IMPORTANT:
The STAND-BY SWITCH should not be used in lieu of cleaning and
sanitizing procedures specified by local regulatory agencies.
Mix Low Function
This model will sense when the mix is low in the hopper. The mix low light will illuminate continuously for 2 minutes. After 2 minutes the light will begin to blink off and on for the next 8 minutes.The buzzer in the mix out circuit is
2 minutes off and 5 seconds (or 5 beeps) on for a total of 10 minutes.At the end of the 10-minute time the

buzzer is out of the circuit and the light will illuminate fully again.After the 10-minute cycle the mix out safety function is activated making the unit inoperable. The machine is placed into the standby mode to prevent any damage to
the machine from running dry of product. The unit can be reset back to the freeze mode by simply adding mix into
the hopper.
1. If the unit is low in mix or the unit shuts down due to extended mix low condition (“Mix Low” safety function
has activated), refill hopper with fresh product. The unit will automatically revert back to its original operation
mode.
2. If the mix low safety function has activated disabling the unit, and the product has not been added for an
extended period of time - verify the product is okay for re-use. If it is not, use fresh product to restart the
unit. Empty the unit of old product and follow sanitizing (page 14) and start up procedures (page 5).
Product Tips
The Model 5311 & 5511 was designed to dispense a wide variety of frozen beverages including smoothies, frozen
cappuccino, shakes and frozen cocktails. These products can be served in consistencies ranging from thin to
fairly thick. For optimum long-term freezer reliability, it is recommended that product thickness not be set too thick.
Two types of white plastic dispensing valve plungers are available. One style, part W048.0462, is used to serve
these thin to medium products such as cappuccino and cocktails and has one horizontal outlet slot. The other
plunger, part W048.0463, is used to serve thicker product such as shakes and smoothies and has two horizontal
outlet slots. These plungers are interchangeable.
Over an extended period of time some products, such as frozen cocktails that contain alcohol, have a tendency to
separate, or stratify. Separation of product in the mix storage hopper can result in frozen product quality
inconsistency. Simply keeping the product stirred on a regular basis will eliminate this problem.
Some of cappuccino or latte' mixes contain dairy products which can spoil if not refrigerated. If the freezer is to be
turned off at night these products m
ust be removed from the freezer.
Contact your local health department
regarding its regulations for proper mix handling and storage.
Pr
oduct Consistency Adjustment (see Figure I)
1) Remove the front electrical box cover by removing the two screws.
(See figure C).
2) If the product in the cylinder has been frozen for more than 30
minutes, draw out 16 ounces (1/2 liter) before
checking consistency.
3) Turn the consistency control knob, located at the top center of the
circuit board, clockwise to achieve a colder setting or thicker
product or counter-clockwise to achieve a less cold setting or less
thick product. (
See Figure I, page 10).
CAUTION: This control setting is very sensitive so always make
small adjustments. If you visualize this control as a clock face,
with the adjuster set all the way counter-clockwise it would be 5:00.
A recommended setting is 7:00. This would be the warmest
setting the machine has. A one-hour change will make a noticeable
difference in product consistency.

Product Consistency Adjustment (cont.)
4) When making adjustments to a thicker (colder) setting, dispense approximately 16 ounces (1/2 liter) of
product and recheck consistency after the compressor has cycled off.
5) If the consistency is still not correct, repeat steps 2 and 3.
"Standby" - Freezing Cylinder Temperature Adjustment
1) Remove the front electrical box cover. (
See Figure C).
2) For a colder setting, turn the "Barrel" control adjuster, located at the top left of the circuit board,
counter
clockwise.(See Figure I, page 10).
CAUTION: This control setting is very sensitive so always make small adjustments. If you visualize
this control as a clock face, a one-hour change will make noticeable difference in freezing cylinder
product temperature. A recommended setting is 11:00.
Hopper
Temperature Adjustment
1) Remove the front electrical box cover.
2) For a colder setting, turn the "Hopper" control adjuster, located at the top left of the circuit board, counter
clockwise. (
See Figure I, page 10).
CAUTION: This control setting is very sensitive so always make small adjustments. If you visualize
this control as a clock face, a one-hour change will make a noticeable difference in hopper product
temperature. A recommended setting is 10:00.
Note: Some models will have a built in feature (in the freeze mode) that will make the machine inoperable if
the mix gets low and is not refilled after ten minutes. (The normal sequence is five beeps every two minutes
for a total of ten minutes, then shut down occurs until the unit is refilled). These same units will also have a
forty-five second dasher run time after the compressor turns off.
Consistency Control - Overview
The “freeze” mode consistency setting adjusts the frozen product thickness.In the “freeze” mode, as the liquid mix
in the cylinder freezes, it becomes harder for the motor to turn the dasher assembly.The control board senses the
amount of energy that the drive motor consumes as it rotates the dasher assembly through the product in the cylinder.The control board will turn the compressor and barrel solenoid valve off at the proper consistency.The drive
motor will continue to run for 45 seconds after the compressor is cycled off.This is called the blending cycle. After
the blending cycle is complete the drive motor also is shut off.The drive motor and compressor will run together at
any time refrigeration is required in the barrel.The compressor will run independently for the hopper if required.The
hopper is controlled by temperature.The thermister will signal the board and the board will start the compressor
and open the hopper solenoid valve.
The unit will remain off until either the timer in the control board (either 10 or 15 minutes dependent upon which
value is selected) restarts the drive motor.In this case the drive motor will run for 45 seconds and if no refrigeration
is required the drive motor will then shut off.If refrigeration in the barrel is required the freeze cycle is repeated as
well as the blending cycle.The unit will also restar t the drive motor if the plunger is raised. The plunger switch will
start the drive motor and remain on as long as it is held open. After the plunger is closed the drive motor will continue to run for 45 seconds.The compressor will start, and barrel solenoid valve will open.If refrigeration is required
during this time the freeze cycle and blend cycle will follow.
CAUTION: SHOCK HAZARD
THIS ADJUSTMENT REQUIRES REMOVAL OF THE ELECTRICAL BOX COVER AND SHOULD BE
MADE BY A QUALIFIED SERVICE TECHNICIAN.

Consistency Control - Overview (cont.)
In the “standby” mode the control board senses the temperature of the product in the barrel.The dr ive motor is
cycled on time only. It will operate for 2 minutes ON then 18 minutes OFF as long as it is in “standby”.The compressor and drive motor are cycled independently for the barrel in the “standby” mode. Once the barrel thermister
signals to the board, the board will start the compressor and the barrel solenoid valve will open as refrigeration is
required. It will continue to run until satisfied. The plunger switch is disabled and the drive motor will not start when
the plunger is opened.The hopper is still controlled by temperature. If the thermister signals a raise in temperature
the compressor will start and the hopper solenoid valve will be opened. It will continue to run until satisfied.
In the “clean” mode the drive motor will run continuously. (The compressor will not run in the “clean” mode.) This is
for emptying out product for cleaning purposes.
There are eleven (11) lights on the circuit board that indicate the following: (See Figure I)
BARREL (D1) - Illuminated when the freezing cylinder (barrel) has achieved the pre-set temperature in the
"Stand- by" mode.
HOPPER (D2) - Illuminated when the hopper has achieved the pre-set temperature in the "Stand by" mode.
WASH (D3) - Illuminated when the mode switch is in the wash or "Clean" position.
FREEZE (D4) - Illuminated when the mode switch is in the "Freeze" mode.
DISPENSE (D5) - Illuminated when the dispensing valve is open calling for both the compressor and drive
motor to operate.
GREEN CONSISTENCY (D6) - Off when the motor and compressor are off. Illuminated when the
compressor and dasher are bringing product to preset consistency. Blinks as preset consistency is
achieved and then goes out.
RED CONSISTENCY (D7) - Blinks as preset product consistency is approached. Glows steadily when
preset consistency is achieved and then goes out.
COIL (D8) - Compressor contactor energized
COIL (D9) - Drive motor coil energized
COIL (D10) - Hopper refrigeration solenoid coil energized
COIL (D11) - Freezing cylinder refrigeration solenoid coil energized
