OPERATING & 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 9.

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 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.

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 determine 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 important? 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 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 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 ensures 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.

Page 8 Crathco®5000 Series Manual

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

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 Lo

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 and start up procedures.

Product Tips

The 5000 Series 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.

Product 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).

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).

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).

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.

Consistenc

y Control - Overvie

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.

CAUTION: SHOCK HAZARD

THIS ADJUSTMENT REQUIRES REMOVAL OF THE ELECTRICAL BOX COVER AND SHOULD BE MADE BY A QUALIFIED SERVICE TECHNICIAN.

Crathco®5000 Series Manual Page 11

Consistency Control - Overview (cont.)

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.

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 "Standby" mode.

HOPPER (D2) - Illuminated when the hopper has achieved the pre-set temperature in the "Standby" 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.

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 clear 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° Fahrenheit (50° Centigrade) water to achieve a concentration 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 Z)

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 Figure AA & BB)

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 CC. Insert the larger front and smaller rear white plastic bearings into dasher, then slip in the stator rod. Attach scraper blades.

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 in Figure DD. 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 EE)

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.

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.

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.

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.

5. Slide filter into top of filter cover with removal clip up and the air flow arrows facing the existing panel.

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

until electrical power has been disconnected.

How to Clean Condenser

Note: Loss of refrigeration efficiency will result if condenser is allowed to become dirty. Excessive compressor run

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).



Crathco®5000 Series Manual Page 19

Ann

ual Maintenance (cont.)

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. Reinstall side and back panels.

9. Re-connect power supply.

Belt Adjustment

Check the belt tension. The proper belt deflection is 1/2" overall. 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 (#W038.0009). 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 motor cradle by two allen bolts on each bearing.

3) Loosen the allen bolts on each bearing. Do not loosen the set screws 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. Be sure the setscrew is tightened down flat on the motor shaft.

9) Return the unit back to service.

CAUTION: Unplug the machine before performing any adjustments. This procedure must be done by a qualified technician.
