Operation & Adjustments

How to Operate:

1) Sanitize unit following the cleaning instructions on page 12.

2) Fill hopper with product. Allow barrel to fill with product to the proper level, then install carb tube.

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 10.

Mix Considerations - General

Freezing characteristics are affected by the amount of sweeteners and solids in the mix. The amount of sweeteners and solids is 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. It is normal for output capacity to decrease when warm mix is added, or when the freezer is operated in a warm area

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 diary based shake mixes, the proper mix to air ratio is generally accepted to be two parts mix to one part 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. This 50% increase in volume from liquid to frozen product is referred to as OVERRUN.

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 the carb 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. Grindmaster Corporation’s 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 determine how much mix to add to the freezing cylinder at start-up. This can be done by watching the level of mix though 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.

Crathco®5512 Manual Page 7

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 frozen product volume. For example, if one gallon (1) (4.4 liters) of liquid mix is poured into a freezer and one and a half gallons (1/2) (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 important? The introduction of air into the finished frozen product is essential from two stand points...taste and profitability. Frozen product with a low percentage of overrun costs more to serve, 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 seems to be a good average. The ingredients in some mixes take on and hold air easier.

Overrun also effects profitability. For example, an increase from 25% to 50% overrun represents a mix savings of 17%.

Uniform overrun 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 with liquid mix, 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.

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 and a full cup of frozen product weighs 15-1/2 ounces, 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.

Standby Switch

The "STANDBY" 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 cylinders to proper serving consistency.

At the start of the “STANDBY” period:

1. Fill the hoppers with fresh mix.

2. Select the “STANDBY” mode...the front panel “STANDBY” lights will illuminate.

3. Turn the carburetor outer tubes to the OFF position (between any two holes). This will prevent any mix from flowing into the freezing cylinder and reducing overrun. NOTE: Loss of overrun is one of the main reasons for soft, wet looking frozen product.

At the end of the “STANDBY” period:

1. Turn the carburetor tubes back to their original setting.

2. Turn the switches to the “FREEZE” position. The FREEZE lights will illuminate.

3. When the freezer cycles off by reaching the desired temperature you are ready to start serving.

IMPORTANT: The STANDBY SWITCHES 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 12) and start up procedures (page 6).

Product Tips

The Model 5512 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 reIiability, it is recommended that product thickness not be set too thick.

Two types of white plastic dispensing valve plungers are available. One style, P/N W0480462, is used to serve thin to medium products such as cappuccino and cocktails. This plunger has one horizontal outlet slot. The other plunger, P/N W0480463, 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 and lemonade, have a tendency to separate, or stratify. Separation of product in the mix storage hopper can result in frozen product quality inconsistencies.

Crathco®5512 Manual Page 9

Product Tips (cont.)

Some 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 must be removed from the freezer. Contact your local health department regarding

their regulations regarding proper mix handling and storage.

Consistency Control - Overview

CAUTION: SHOCK HAZARD! THIS ADJUSTMENT REQUIRES REMOVAL OF THE ELECTRICAL BOX

COVER AND SHOULD BE MADE BY A QUALIFIED SERVICE TECHNICIAN.

An electronic circuit board, mounted inside the front electrical box, controls the consistency (thickness) of the frozen product in the “Freeze” setting, and controls the freezing cylinder and storage hopper temperature in the “StandBy” mode.

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 thermistor 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 restart 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.

In the “standby” mode, the control board senses the temperature of the product in the barrel. The drive 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 thermistor 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 thermistor 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.

CAUTION: SHOCK HAZARD! THIS ADJUSTMENT REQUIRES REMOVAL OF THE ELECTRICAL BOX

COVER AND SHOULD BE MADE BY A QUALIFIED SERVICE TECHNICIAN.

The electronic control has three adjusters; one to set the “Freeze” mode product consistency (thickness), one to set the “StandBy” mode cylinder temperature and one to set the “StandBy” mode hopper temperature. The “Freeze” mode consistency setting adjusts frozen product thickness. Always adjust this control to deliver a frozen product that is as thin (soft) as possible yet is still acceptable to the customer.

There are eleven (11) lights on the circuit board that indicate the following: (See Figure H )

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 "StandBy" mode.

Page 10 Crathco®5512 Manual

Consistency Control -Overview (cont.)

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

Product Consistency Adjustment

1. Remove the Front electrical box cover.

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, (see figure H) located at the right center of the circuit board, clockwise to achieve a colder setting (thicker product) or counterclockwise to achieve a less cold setting (less thick product).

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.

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.

Freezing Cylinder Temperature Adjustment

1. Remove the front electrical box cover.

2. For a colder setting, turn the “Barrel” control adjuster, located at the right top left of the circuit board, counter clock-

wise. (see figure H)

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 FREEZING CYLINDER PRODUCT TEMPERATURE. A RECOMMENDED SETTING IS 11:00.

Care & Cleaning

NOTE: Each time the freezer is disassembled, all internal freezer components must be thoroughly washed, scoured

and sanitized using procedures recommended by your 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 freezer is empty, proceed to Cleaning Following Complete Disassembly of Unit or Daily Cleaning Procedure. If the freezer is full of product, turn the mode switch to “CLEAN”.

2. On freezers using the optional electric pump and tank assembly and optional Remote Fill Control, turn the switch on the Remote Fill Control to “OFF” and unplug the pump.

3. On freezers using the optional Remote Fill Control and Proportioning Pump, turn off the water valve on the Proportioning pump, using the valve next to the inlet pressure regulator.

4. Open the front dispensing valve and drain all product from the freezer. Close the dispensing valve and turn freezer switches to “OFF”.

NOTE: Use approximately 2-1/2 gallons (10 liters) (per side) of cool water to rinse product out of the freezer.

5. Remove the carb tubes and pour water into the storage hopper. Allow the water to fill the freezing cylinders.

6. Turn the freezer panel switches to “CLEAN” for 5 minutes. Open the dispensing valves and drain the water from the freezer.

(See Figure T.)

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. (See Figure U).

NOTE: Carefully inspect the O-Rings and replace if necessary.

3. Remove the dasher assembly taking care to avoid damaging the rear seal assembly at the back of the freezing cylinder.

4. Remove stationary portion of the shaft seal assembly from the back end of the freezer cylinder. This is accomplished by reaching into the cylinder and pulling seal out with your index finger. (See Figure V).

5. Slide the rotary seal off the the auger shaft. Inspect both seal components 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. Wash all components in a detergent solution, sanitize and allow to air dry.

Cleaning Following Complete Disassembly of Unit (cont.)

IMPORTANT: After disassembly, thoroughly scour each part of the freezer in a warm mild detergent solution including the inside of the freezing cylinder and the mix storage hopper. Rinse each part with clean water. Prepare a minimum of 3 1/2 gallons (13 liters) of sanitizing solution (Divorsol CX or equivalent) following the manufacturer's instructions.

NOTE: Add 3 ounces (85.4 mg) of Divorsol CX to 3 1/2 gallons (13 liters) of 120°F

(50°C) water to achieve a concentrations of 200 parts per million. Dip or wipe each part in sanitizing solution and allow them to dry on clean paper toweling.

Reassembly

1. 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 FIRST, with the smooth sealing surface toward the back of the auger. (see figure W)

2. Insert the stationary portion of the seal into the grooved rubber boot with the polished surface facing out (forward). Lubricate the grooved exterior portion of the boot and insert it straight back into recess at the back of the freezing cylinder, RUBBER FIRST. (see Figures X & Y)

NOTE: If the circular portion of the seal is white, make sure that the groove is toward the rubber (back of freezer).

3. Reassemble the dasher assembly, as shown in Figure Z. 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.

4. Reassemble the dispensing valve assembly as shown on Figure AA. Thoroughly wash and sanitize all components, lubricate the inside bore of valve body with a thin film of food grade sanitary lubricant. Reinstall the O-Rings on the plunger assembly and lubricate the entire plunger. Reassemble the valve and replace the retainer pin. Inspect and lubricate 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.

5. Disassemble the carburetor assembly and remove the O-Rings. Wash and sanitize all parts.

6. Reinstall and lubricate the O-Rings and slip on the outer tube if equipped. (See Figure BB.) Repeat reassembly on the other side.

Sanitizing and Refilling

1. Prepare a minimum of 3-1/2 gallons (13 liters) of sanitizing solution (Divorsol CX or equivalent) following the manufacturer's instructions.

NOTE: Add sanitizer to 3-1/2 gallons of water (warm) to achieve a concentration of 200 parts per million.

2. Pour sanitizing solution into the mix storage hopper and allow the solution to fill freezing cylinder. Use a brush to clean the hopper sides and bottom. (Repeat steps 1 & 2 for opposite side.)

3. Turn panel switch to "CLEAN" and allow freezer to run for 5 minutes.

4. Open dispensing valve and drain solution. Turn freezer to "CLEAN" for a few seconds to allow the auger to push remaining sanitizer out of the freezing cylinder.

5. If you are using a concentrated product, mix the product according to the manufacturer's instructions.

6. Open dispensing valve. Pour product into the hopper and allow this product to chase out any remaining sanitizer. Watch the product flowing out of the dispensing valve and close the valve when the new mix has purged the sanitizer remaining in the cylinder.

7. Sanitize and install the carburetor. (Figure R). Refill mix hopper.

8. Turn front panel switch to "ON". Allow approximately 20 to 30 minutes for the freezer to reach proper

consistency. Repeat on other side.

Maintenance

WARNING!

Disconnect power for maintenance. Do not attempt to perform maintenance on the freezer

until electrical power has been disconnected.

Suggested Weekly Maintenance

1. Clean, lubricate and sanitize the freezer following guidelines in Care and Cleaning on page 11.

2. Clean the exterior of the freezer using a soft wet cloth.

Suggested Monthly Maintenance

How to Clean Exposed Filter:

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.

Page 16 Crathco®5512 Manual

How to Clean Concealed Filter:

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.

time or loss of capacity is 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 condenser opposite the fan motor.

4. Use compressed air or CO

to blow out dirt from the fan side of the condenser.

5. An alternate cleaning method is to use a condenser brush and a vacuum cleaner.

CAUTION: Procedure can create a loud noise.

Ann

ual Maintenance

1. Disconnect electrical power.

2. Clean condenser.

3. Remove dispensing valve assembly and replace all “O” Rings. (See Care and Cleaning)

4. Remove dasher assembly, inspect stator bearings and replace shaft seal set. (See Care and Cleaning)

5. Remove rear panel and inspect “V” belt.

6. Inspect the drive shaft square hole for wear (rounding out).

7. Check drive shaft and motor shaft bearings for excessive wear.

8. Replace side and back panels. Re-connect power supply.

Crathco®5512 Manual Page 17

Belt Adjustment

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.

1. Unplug the machine and remove both side and the rear panels.

2. Locate the motor flange bearings. These are the pillow block 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 motorcradle 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.

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, remove the setscrew from the motor pulley and move either in or out as needed.

8. Reinstall the setscrew. Use non-permanent loc-tite on the setscrew and tighten it back down on the motor shaft. Please be sure the setscrew is tightened down flat on the motor shaft.

9. Return the unit back to service.
